Cyfac Piste Max

Would be interested to hear what type of threading is on yours! Thanks in advance!
@gaston is there some way of findig out whether the hub is french threaded? Judging by the fact that a plated cheapo generic cog went on fine, I think the problem is with the EAI cog and the threads are actually ita or british.

Maybe I should just go with 3/32 and the original 50t mavic ring + 17t cog. It would also save me the hassle of finding the special chainrings as explained on the last page.

3/32 is lighter too

I know and it served me well so far. As a matter of principle I wanted 1/8 on my vanity tarck bike but I'm not sure if it's worth the hassle.

try Miche

Well, I tried with these two cogs and they went in nicely:

Then I tried with another eai cog I have (3/32) and it's the same problem, it wont engage after a few threads.. I don't have a recent hub to thread it onto.

I think you have a BSC threaded hub as mine and you're stuck with older cogs unless you force newer cogs onto it, turning it into ISO..

ps: another way of getting around the ratio issue would be trying smaller chainrings on your 631 or getting a 632 which has smaller spider arms.. ;)

Wow, thanks a lot for your efforts, that is really helpful. I'll keep looking for a matching cog and see if I can use the EAI cog on a different bike.
@Gaston I'll consider that but I'm not a miche fand tbh, thanks for the tip though :)

My Max is build...

Pics please!

no sun : /

drops, stem, and seatpost ITM millenium, SMP, CXP33 and Campag 10s...

fair enough :)

so good!

If anybody has a 1inch quill Look ergostem in silver which he/she is willing to part with, please let me know. Having second thoughts about a black one, silver would be preferable :)

It's TI time :) thanks to @kgrev for posting the seatpost!

It arrived! I'm glad it all worked out

Cheers, quite a relief that it was resolved quickly :)

nice!

how's the cog hunt coming along?

I didn't sell my Cyfac in the end and Bernburg is so flat that it would be rude not to bring it over at Christmas with some cheapo wheels for cutting about campus on...

Nice seatpost but saddle squashed like many flite of the 90...You can fix that with leaving a tshirt hardly stuck between sit and rails during 4 months...

Haven't done much hunting tbh, I think I'll get a 3/32 17t when I order a chain and some other bits once I got all the other parts together. Good call on not selling the cyfac! Would have been a shame to sell it before you even got to enjoy it and if you need the money at some point you'll probably get more for it if you sell it in germany (prices for track stuff are rather high due to scarcity).

In other news: I found a starfish in better condition which is nice cause the one I had was more suitable for a beater bike.
The Mavic Bars I found on here are really nice but the base bar is a bit wide (42c-c/ 44 from side to side) for my taste so if anybody has a narrower one and is interested in a swap, please let me know!
And I'm still negotiating and weighing my options for stems.

3/32 makes most sense tbh, unless you've the thighs of Forstemann I don't think it makes much difference so long as your drivertrain is set up well.

Cycled once in Germany so far, been shouted at once for using the road when there was a path. A path that was closed for construction work. Arschlochs are not unique to any one nation, are they?
