Ah |
The Grin V7 doesn't fit 14mm axles unfortunately. |
I'll likely continue to be annoyed about that until/unless they eventually make a 14mm-compatible one. lol |
Idk how I have missed these new designs tho |
Looks pretty epic |
Gonna buy a new hub just to be able to use that arm lol |
They were only just added to the site within the last month or two, and only have been in-stock (well, they go in and out lol) for a few weeks. |
I recall browsing not to long ago, and decided to ask here now |
I'm going to be picking up at least a V7 pretty soon, once I've got the money to throw at a bunch of small things I've been meaning to pick up from Grin for a while. |
I’m not because I just spent way too much on camera stuff |
Yeah, other recent expenses are why I haven't put the order in already. Was planning to grab it as soon as it was available, but that money went elsewhere. |
Instead of a pinching arm you can simply use 2 arms pre-torqued in opposite directions |
My current setup is that. I've still had issues with axle movement, and my dropouts are a bit ragged because of it. |
Not saying it can't work, or even that it can't work with my hardware. |
Just looking to minimize the potential for issues, regardless of root cause. |
You got a proper spot welder yes? How are your packs made with bare lipo holding up? |
I think you’re thinking of a different person |
What makes it specifically for regen braking systems |
Yea its just kinda sad 14mm didn't get a clamping dropout |
And why is v7 torque arm better than standard ones |
hopefully they release one if the 12mm clamping dropout sells well? |
It's going in and out of stock, so I think it's a safe guess that it's selling well so far. lol |
it physically clamps the axle, meaning part tolerances are no longer an issue |
During regen, the axle wants to rotate in the opposite direction to drive |
That's pretty nice |
Yea. Any axle wiggle tends to.. wear and bust things over time |
So this causes wobble/wear? |
If your torque arm is not perfect, and it never is, yea. |
Ahh |
Nice |
though I do wonder if the new V5/V6 are using hardened inserts that are going to wear a LOT less |
I would said some 4mm but sure lol |
Yep. |
Instead of pushing in one direction (during drive) and letting off (when you let off the throttle), with regen, it's pushing hard back and forth repeatedly. Much more stressful. |
that little bit of slip lets it gain speed and smash into things |
Yeah I can imagine especially seeing as these are DIY kits with variable tolerances |
Even a clamping mechanism isn’t perfect because it’s relying on bolts that can loosen with vibration |
Oh, I think that center bit actually has a slot down the side |
neat |
True, but a clamping mechanism is still better than *not* a clamping mechanism, at least when you're not in perfect control of the tolerances of all relevant parts (which you're absolutely not). |

grins intergrated torque arm motors look amazing though, gotta admit |
Like, trying to put all that torque through 14mm shaft is kinda crazy anyway. |
If I make a hub motor bicycle I'll probably go with a geared hub motor |
Grin has several geared hub motors now that can regen. |
It's actually why they developed the V7 torque arm. |
https://ebikes.ca/product-info/grin-products/all-axle-hub-motor.html this thing! |
That's my front hub. :D |
Can confirm, is good. |
Wow the all axle can be stub mounted too? neat |
I still want to move mine over to thru-axle. |
Going to pick up the thru-axle adapter when I put in my next Grin order, though I'm not sure when I'm getting the new fork. |
Apparently they already have a V2 of it since 2019. |
Off the top of my head, I forget if mine is a late V1 or an early V2 |
Looking at the timing of my order, probably V2 |
2 weeks |
Oh, yeah, the V1 had Andersons, so mine's definitely a V2. |
Yeah that sounds right |
didnt even realise until you said about v7 since i was away |
it still doesnt come up under the torque arm page |
only the main page |
Yeah they haven't updated the torque arm info page. |
It's been in the Torque Arms page of the shop since it came in stock though. |
Yeh I need a good torque arm |
Or at least a better mounting mechanism |

Found one!!!1!1 |
So I broke 7 spokes going to work today when my 10spd chain fell into the void between 1st and the spokes. I didn't have a spoke guard... |
Now am temporarily running this 7 speed rear wheel i quickly put on while working at the shop |
Sucks, but good lesson to properly adjust the stuff and use a spokeguard just in case |
Been there... 10 speed chain fits 7 speed? |
Is that a dork disc is another device? |
Yes from 8 speed onwards the chain is just thinner |
Also the chain shouldn't drop on the lowest gear of it was indexed correctly |
L limit screw got buggered over time |
Even riding down the staircase and then jumping off a 7 foot drop? |
well yes |
how else would mountainbikers and downhillers ride fine |
I wonder how many of them ride down in 1.st |
X |
well for one mountain bike derailleurs have a clutch |
to prevent the chain slapping |
and 2 if your Limit screws are correct you wont drop the chain going into lowest gear |
Dork discs are just a legal requirement to be included in purchased wheels/bikes |
most people dont use them |
@Oendaril @Aramož chances are my derailleur hook claw hanger, which can be bent with the mere push of a finger, is what's responsible |
with your bike on a stand can you downshift while pedaling and drop the chain |
I don't have a chain On atm |
Rather not damage stuff rn |
Which is technically not legal for an ebike |
it could be if it is bent too many times, there's a tool that lets you check hangers |
if you know which hanger it is i'd just buy one to be sure |
It's not just a hanger |
It's a hook claw dropout adapter |
^^^ |
And I ain't getting a stronger one out of fear of damaging my frame ree. |
The black metal protects the derailleur from getting bent all the time. Without it, this bike would be pretty useless. |
i dont get why u wouldnt just buy a stronger/better hanger |
"Damaging frame".... Hanger will snap before damaging ya frame |
Because there doesn't exist such a thing for what I need. Can't get this in a stronger aluminum. |
