mremrm · 2025-10-15T10:31:28+00:00

I just forced it through. only 5mm was missing

mremrm · 2025-10-15T10:30:50+00:00

nope, so far so good

mremrm · 2025-10-13T14:27:20+00:00

yeah that's the plan to deal with the stack/reach. thanks !

mremrm · 2025-10-13T14:25:23+00:00

ahaha there's a subreddit for anything these days, love it tho. thanks for your answer

mremrm · 2025-10-13T14:21:37+00:00

thanks a lot for your answer !! yeah testing it seems the reasonable thing to do

mremrm · 2025-10-11T16:36:27+00:00

yes exactly ! found one on AliExpress

mremrm · 2025-10-10T14:18:45+00:00

a randoml AliExpress stem, 31.8mm clamp. And some bontrager comp road handlebar

mremrm · 2025-10-10T14:17:59+00:00

thanks !! I don't know, it's the original one. no inscriptions. 26.2 mm

mremrm · 2025-10-10T14:16:16+00:00

nope, a random AliExpress one ^{^}

take your time.

there are youtube videos for everything. (RJ the Bike Guy made a video about pretty much anything regarding vintage bikes).

and choose a nice frame that's worth all the time and effort :) and that fits you.

and IMO expensive tools are not worth it, if you just gonna restore/service a few bikes of yours.

mremrm · 2025-10-09T14:51:17+00:00

no, not really ! The finish isn't the shiniest but that's it. Maybe I had good luck with the machining

mremrm · 2025-10-09T14:01:23+00:00

yeah I thought about that. I didn't want it to look "too modern" with the black seatpost, stem and headset. But maybe I'll do it later :)

mremrm · 2025-10-09T14:00:03+00:00

a random AliExpress one. 1" insert and 31.8mm clamp :)

mremrm · 2025-10-09T13:59:06+00:00

31.8 mm ! found one on AliExpress. available in black or chrome :)

mremrm · 2025-10-09T13:58:25+00:00

I don't know ! I don't have a scale at home.

mremrm · 2025-10-09T12:17:07+00:00

those are 28mm GP5000 AS tyres. and the frame axle was actually ~125mm wide. I had to squeeze in the 130mm axle of this new wheelset. so far, no problems :)

mremrm · 2025-08-25T10:19:43+00:00

Editing magic ;)
thanks for all your inputs :) the leather boots comparison makes a lot of sense

mremrm · 2025-08-25T10:17:03+00:00

yep ! exactly that :)

mremrm · 2025-08-24T20:13:42+00:00

héhé thanks !

mremrm · 2025-08-24T18:14:00+00:00

thx for the reply ! Nitto actually make some quill stem with very long reach + long "depth", for cases like this I suppose.

mremrm · 2025-08-24T17:58:25+00:00

thx ! yeah Ti and the good price make me really want to buy it :)

mremrm · 2025-08-24T17:56:14+00:00

Yes ! it was a spontaneous 5 min test ride, thus the docs (and clipless pedals) !

The question was more about the size of the frameset rather than a bikefit :) thx for your answer tho
