1 [00:00:00,000 --> 00:00:00,260] A: 4,
2 [00:00:00,000 --> 00:00:21,840] E: three one ok antonio we have to replace the front inner tube in the mountain bike that is in front of you behind the column stand which is this white one with yellow writing and red shades so get closer to the
3 [00:00:00,920 --> 00:00:02,240] A: 3,
4 [00:00:03,120 --> 00:00:06,200] A: 2, 1
5 [00:00:24,559 --> 00:00:35,480] E: bicycle and the first operation to do in the meantime is to loosen the brakes to loosen the brakes you must locate the brake caliper in front
6 [00:00:32,000 --> 00:00:33,400] A: 4,
7 [00:00:36,060 --> 00:00:42,580] E: on the bike itself ok ok you have to take these two black levers
8 [00:00:43,139 --> 00:01:28,260] E: bring them closer with one hand then keep them pressed with one hand the black levers you can see the two black rods ok perfect you have to crush them with one hand and remove this silver tube from the metal guide ok perfect perfect now back to the workshop go to the chest of drawers the one with the orange edges exactly this one open the third drawer at the top there are the combination keys all on the left perfect you have to take the largest of all which is the 15 mm good perfect go back to the bicycle
9 [00:00:48,880 --> 00:00:54,279] A: 3 2 1
10 [00:01:16,400 --> 00:01:17,800] A: 4
11 [00:01:18,360 --> 00:01:29,980] A: 3 2 1
12 [00:01:30,779 --> 00:01:42,019] E: go down to the height of the hub you have to unscrew the two 15 mm bolts which are there, one on the right, one on the left, exactly these you can
13 [00:01:37,519 --> 00:01:38,559] A: 4
14 [00:01:39,080 --> 00:01:41,660] A: 3 2 1
15 [00:01:44,379 --> 00:02:08,289] E: remove them from the pin itself when they are loose you can also proceed with your hands once you hurry even before then on this side I think that's enough move on to the other side that's enough that's enough that's enough on the other side same operation
16 [00:02:14,559 --> 00:02:16,720] E: maybe a little harder ok perfect
17 [00:02:21,460 --> 00:02:38,240] E: once they're slow, I repeat, you can also unscrew them with your hands, it's the same, it's quite soft, ok, firm, that's enough, that's enough, now you should exactly move the two washers away from the fork, perfect both on the right and on the left.
18 [00:02:27,580 --> 00:02:29,979] A: 4 3 2 1
19 [00:02:39,100 --> 00:02:39,940] E: left
20 [00:02:39,919 --> 00:02:43,679] A: 4 3 2 3 2 1
21 [00:02:44,300 --> 00:03:07,960] E: perfect and now you simply have to remove the wheel from the fork then lift the bicycle ok you can place the bicycle on the ground with the tips of the fork and it will stand on its own very well now look for a support surface that is comfortable for you or it could be wherever you are most comfortable perfect
22 [00:02:58,899 --> 00:03:01,100] A: 3, 2,
23 [00:03:06,160 --> 00:03:07,559] A: 1
24 [00:03:09,460 --> 00:03:18,759] E: then you put this one back there then you can see the valve of the radio chamber the one that is on the rim that pin that comes out more often than the others
25 [00:03:09,839 --> 00:03:11,860] A: 3 1
26 [00:03:12,880 --> 00:03:14,279] A: 3
27 [00:03:19,000 --> 00:03:40,080] E: perfect then unscrew this cap not everything is enough so squeeze and let out the residual air in the inner tube if nothing comes out you have to unscrew more without counterclockwise so you are avoiding ok perfect let all the air out
28 [00:03:28,539 --> 00:03:29,960] A: 1 3
29 [00:03:36,720 --> 00:03:38,119] A: 1
30 [00:03:41,259 --> 00:04:17,140] E: pressing repeatedly while still keeping it unscrewed if nothing comes out anymore that is completely deflated air still comes out and continues even touching the tire with your hands you should realize how much air there is I think it's perfect then ok you can remove this cap completely now you also have to remove that washer that is at the base of the valve this one here
31 [00:03:43,399 --> 00:03:47,460] A: 3 2 1 3 2
32 [00:03:53,899 --> 00:03:54,600] A: 1

36 [00:04:18,420 --> 00:04:19,480] E: exactly good
37 [00:04:29,880 --> 00:04:29,920] A: 1
38 [00:04:33,320 --> 00:04:45,140] E: good very well then exactly under you there is a row of drawers where you are where you are in this station you under you there is exactly the central drawer
39 [00:04:47,239 --> 00:04:48,420] A: 3 1
40 [00:04:48,420 --> 00:05:34,000] E: you see there are some red levers yes take those the exact two of these one and another no this is the flat one use the other yes exact ok and given that if you also take the inner tube this one yes perfect that will be used for replacement then these levers that in your hand hunt tires if you see they have a flat side a flat side like a paddle perfect this flat side you have to insert now between the tire and the exact rim in this direction on the contrary on the contrary sorry I'm perfect insert it well and you have to pry you have to pry to pull the tire off
41 [00:04:49,559 --> 00:04:51,880] A: 3 2 1 3 2
42 [00:04:52,859 --> 00:04:54,420] A: 1 3 2
43 [00:05:00,359 --> 00:05:01,440] A: 1

46 [00:05:31,720 --> 00:05:32,519] A: 2,
47 [00:05:34,260 --> 00:05:39,100] E: from the circle you will probably need both
48 [00:05:40,579 --> 00:05:42,200] E: in the meantime hook one up
49 [00:05:45,779 --> 00:05:49,839] E: see if you can peg just the edge of the tire rim
50 [00:05:52,579 --> 00:05:54,839] E: you can get it
51 [00:05:52,959 --> 00:05:53,779] A: 1 3
52 [00:05:57,459 --> 00:06:02,600] E: then crush the tire with your fingers to make room
53 [00:05:57,579 --> 00:05:58,140] A: 1
54 [00:06:05,920 --> 00:06:10,220] E: Be strong, don't worry, the inner tube needs to be changed
55 [00:06:12,739 --> 00:06:13,299] A: 3
56 [00:06:14,179 --> 00:06:48,299] E: now you have to lever towards you this bead must come away from the tire from the rim so it's perfect perfect pull maybe you took both edges pay attention exactly take just one perfect edge and pull away towards you perfect so now if you can also insert the other key yes you will need it to increase the leverage and squeeze make sure that this bead is perfect but help yourself with your hand by also pulling
57 [00:06:15,820 --> 00:06:16,839] A: 2 1 3 2 1 3
58 [00:06:17,140 --> 00:06:17,700] A: 2

61 [00:06:47,619 --> 00:06:47,679] A: 3 2
62 [00:06:48,420 --> 00:06:55,440] E: perfect perfect now if you can if you can slide these levers
63 [00:06:56,940 --> 00:07:34,799] E: following the circumference of the rim and always lever like this you are leveraging to retract the tire the tire must come out so you have to lever with your hand on the contrary look with your right hand you are pressing downwards you have to pull upwards perfect perfect perfect perfect the meaning is then by using manual skills you will personalize the operation perfect yes yes yes yes yes perfect okay okay
64 [00:07:14,320 --> 00:07:15,239] A: 3 2 1 3
65 [00:07:15,720 --> 00:07:17,359] A: 2, 1 3, 2, 1
66 [00:07:29,239 --> 00:07:30,320] A: 3 2

68 [00:07:37,760 --> 00:07:39,399] A: 3 2 1
69 [00:07:41,040 --> 00:07:50,000] E: ok, remove the lever, you don't care about removing the whole tire but the inner tube, so now that one bead is detached from the rim and you have
70 [00:07:42,299 --> 00:07:43,700] A: 3
71 [00:07:43,839 --> 00:07:44,540] A: 2,

73 [00:07:50,619 --> 00:07:55,700] E: access with your hand you have to fish no the other one you don't have to remove it with your hand
74 [00:07:51,440 --> 00:07:53,279] A: 3 2 1
75 [00:07:57,160 --> 00:08:03,500] E: lift the edge of the tire a little and try to pull the inner tube away
76 [00:08:00,679 --> 00:08:02,079] A: 3,
77 [00:08:02,519 --> 00:08:03,920] A: 2,
78 [00:08:04,260 --> 00:08:08,140] E: old you should also see it
79 [00:08:11,779 --> 00:08:15,540] E: perfect literally pulls away by force
80 [00:08:15,339 --> 00:08:15,380] A: 1
81 [00:08:16,320 --> 00:08:16,459] A: 3 2 1 3 2
82 [00:08:16,959 --> 00:08:21,440] E: there's the valve there so first you should get out exactly you better start from here
83 [00:08:18,119 --> 00:08:18,200] A: 1 3 2
84 [00:08:23,220 --> 00:08:24,739] E: exactly perfect
85 [00:08:29,339 --> 00:08:29,579] A: 1 3 2 1 3 2
86 [00:08:30,239 --> 00:08:30,299] A: 1 3
87 [00:08:33,960 --> 00:08:34,000] A: 2,
88 [00:08:44,400 --> 00:08:59,500] E: ok now always helping yourself with your hands by lifting the tire you have to remove the valve from the rim and definitively remove the old inner tube perfect place it where you think best so it will then be removed like this too
89 [00:08:44,900 --> 00:08:46,299] A: 1
90 [00:08:59,799 --> 00:09:06,239] E: wherever you want ok now take the new inner tube found in the box
91 [00:09:02,580 --> 00:09:03,979] A: 3,
92 [00:09:11,799 --> 00:09:38,479] E: perfect unrolls ok locate the valve ok first operation wait you can't mount it you have to do a couple of operations first in the meantime remove the washer that is on the inner tube the one that the silver washer no no no is on the you have to remove the one that is already there it's perfect then take the
93 [00:09:32,559 --> 00:09:33,960] A: 121345678
94 [00:09:38,219 --> 00:09:38,359] A: 9
95 [00:09:38,799 --> 00:09:58,340] E: cover this one ok perfect this is the old one exactly always on the valve there is the usual cover you see it perfect you have to remove it in the meantime now press press it serves to unlock the valve tac perfect now I'll remove some
96 [00:09:50,299 --> 00:09:50,440] A: 11
97 [00:09:59,859 --> 00:10:32,309] E: everything stopped like this now on the right side when the table the bench ends at there is a floor pump you see it no exactly this one here perfect take it take the head with the small hole insert perfect now insert well squeeze the low one that lever perfect now give it a couple of pumps
98 [00:10:03,599 --> 00:10:03,940] A: 12 13 14 15 16 17
99 [00:10:06,940 --> 00:10:07,640] A: 19
100 [00:10:10,940 --> 00:10:12,340] A: 20
101 [00:10:15,840 --> 00:10:16,539] A: 21
102 [00:10:17,239 --> 00:10:18,260] A: 22
103 [00:10:32,440 --> 00:10:33,919] A: 23 24 25 26
104 [00:10:35,109 --> 00:11:07,429] E: then wait a second you have to grab it no no no it's in good shape don't worry you have to do something try now no no grab it by the valve hold it hold it perfect hold it like this and inflate it now ok that's enough that's enough this operation is used to ensure that when inserted into the chamber inside the tire the chamber does not bend so now remove the inner tube from the from the pump
105 [00:10:39,280 --> 00:10:40,700] A: 27 28
106 [00:10:47,659 --> 00:10:50,280] A: 29 30
107 [00:10:51,159 --> 00:10:56,500] A: 31 32 33
108 [00:10:58,119 --> 00:10:59,520] A: 34
109 [00:11:00,960 --> 00:11:03,880] A: 35 36 37 38 39
110 [00:11:10,109 --> 00:11:29,330] E: perfect, put the cap back on for safety because these tend to leak, don't worry if the air has leaked fine, now take the rim, the wheel and identify the hole and the valve ok insert the valve
111 [00:11:17,659 --> 00:11:19,059] A: 40
112 [00:11:23,859 --> 00:11:23,900] A: 41
113 [00:11:24,940 --> 00:11:24,979] A: 42
114 [00:11:40,429 --> 00:11:52,049] E: very well now take the washer that was removed before wait wait antonio take and insert the and screw it three quarters up to three quarters of its length
115 [00:11:48,880 --> 00:11:49,039] A: 43 44 45 46 47 48 49
116 [00:11:55,250 --> 00:11:59,390] E: even a little more perfect
117 [00:12:04,729 --> 00:12:24,489] E: a little more ok it may be enough now progressively as you are doing first you have to insert the inner tube inside the rim and the tire you can help yourself with one hand by holding up the side of the tire
118 [00:12:08,599 --> 00:12:10,239] A: 50 61
119 [00:12:10,580 --> 00:12:11,700] A: 62

123 [00:12:40,820 --> 00:12:40,880] A: 71 72
124 [00:12:43,309 --> 00:14:00,409] E: perfect squeeze well with your hands at the bottom ok at this point you should do a very simple operation i.e. deflate the inner tube a little because at this moment it is a little too inflated and could give you problems when inserting the tire air comes out of it ok I think it will be enough now progressively you will have to insert the bead of the tire inside the rim basically the reverse operation that we did at the beginning so you have to be perfect exactly exactly this the final part will be harder you will have to do a little more come on so it's better to help with two hands exactly perfect now do one thing make sure it's well inserted check with your hands even shaking it give it a little help to stay inserted properly perfect good at this point you can take the pump again and inflate the tire then unscrew the valve
125 [00:12:48,880 --> 00:12:49,000] A: 73 74 75 76 77
126 [00:13:08,239 --> 00:13:08,320] A: 78

134 [00:14:06,250 --> 00:14:09,210] E: take the pump head
135 [00:14:07,320 --> 00:14:07,359] A: 100
136 [00:14:11,909 --> 00:14:24,580] E: the same operation I did before with the bare inner tube small valve small hole sorry perfect lock the lever lock the lever if otherwise it runs away
137 [00:14:24,840 --> 00:14:24,880] A: 101
138 [00:14:32,049 --> 00:14:38,510] E: wait Antonio you have to lock the lever the lever is still loose the lever this one here is perfect
139 [00:14:37,140 --> 00:14:38,119] A: 102 103 104 105 106 17 18 19 20
140 [00:14:39,739 --> 00:14:40,440] A: 21
141 [00:14:40,090 --> 00:14:44,729] E: perfect, now it shouldn't run away anymore so you can place the wheel on the table
142 [00:14:43,200 --> 00:14:44,599] A: 22
143 [00:14:46,270 --> 00:14:48,929] E: and with two swollen hands it is easier for you
144 [00:14:52,169 --> 00:14:57,229] E: if you turn the pump you see there is a pressure gauge with a graduated scale
145 [00:14:56,739 --> 00:14:58,239] A: 23 28
146 [00:14:58,229 --> 00:15:01,309] E: yes, turn it, turn it, it looks even better, ok
147 [00:15:02,330 --> 00:15:08,489] E: you can move yourself so that the orange hand is on the number 2
148 [00:15:09,340 --> 00:15:10,739] A: 29
149 [00:15:11,169 --> 00:15:16,030] E: which means that in that way the pressure is around two bars
150 [00:15:15,479 --> 00:15:16,880] A: 31
151 [00:15:19,280 --> 00:15:20,679] A: 32
152 [00:15:23,190 --> 00:15:27,890] E: can be enough can be enough
153 [00:15:26,739 --> 00:15:28,219] A: 33 34 35 36 37
154 [00:15:28,390 --> 00:15:32,250] E: unlock the pump unlock the head sorry remove it
155 [00:15:34,070 --> 00:15:42,469] E: perfect screws perfect perfect and puts the cap back on
156 [00:15:36,340 --> 00:15:36,400] A: 38 39
157 [00:15:47,789 --> 00:15:48,849] E: Perfect
158 [00:15:55,320 --> 00:16:01,570] E: and now we have to reinsert the tire, the whole wheel, sorry, inside the bicycle
159 [00:15:55,719 --> 00:15:55,760] A: 40

162 [00:16:02,289 --> 00:16:16,710] E: so lift the fork with one hand, that's right, you can help with that so your wheel hurts, now you have to move both washers, that's right, both, move them all outside first
163 [00:16:10,940 --> 00:16:14,580] A: 47 49 50
164 [00:16:15,320 --> 00:16:16,900] A: 51 52 54
165 [00:16:26,909 --> 00:16:50,530] E: perfect as you will have noticed when dismantling those hooks they must be inserted inside the so maybe it will help you and progressively if you insert one it will be better for you then start screwing with your hands if you can frame it a little lower I am grateful
166 [00:16:33,820 --> 00:16:35,000] A: 55 58 61 62

169 [00:16:53,650 --> 00:16:59,229] E: then wait calmly move all the washers outwards the one on the right
170 [00:17:00,690 --> 00:17:37,390] E: perfect, move them all outwards, there is no need for them to stand up, turn them later so you can leave them, the important thing is that they are on the outside so they don't get in your way, they are both out now with your hands you can turn them over if necessary you can also unscrew the whole bolt and reinsert them ok perfect fantastic perfect same operation I should do it again on the other side it's a bit unpleasant it tends to run away
171 [00:17:11,719 --> 00:17:13,020] A: 66 67 68 69
172 [00:17:16,180 --> 00:17:16,859] A: 70 71 72

176 [00:17:56,369 --> 00:17:57,170] E: Perfect
177 [00:18:00,869 --> 00:18:05,369] E: clearly now you have to take back key 15 which is on the desk
178 [00:18:02,040 --> 00:18:02,079] A: 82
179 [00:18:08,770 --> 00:18:17,469] E: perfect and tighten the two nuts firmly because it must not unscrew in a clearly clockwise direction
180 [00:18:16,640 --> 00:18:16,819] A: 83 84 85 86 87 88 89 90
181 [00:18:30,469 --> 00:18:31,310] E: Perfect
182 [00:18:31,709 --> 00:18:41,869] E: perfect now the last operation we have to do can exactly close the brake caliper place the key somewhere perfect
183 [00:18:45,170 --> 00:18:57,010] E: grab the two arms with one hand to keep them more compressed and possible it is better to grab them with only one hand so you have the other free to reinsert the perfect tube
184 [00:18:45,939 --> 00:18:45,979] A: 91
185 [00:18:46,680 --> 00:18:48,800] A: 92 93 94 95 96 97
