• Long timer lurker, never posted...

    Couple of general questions, thinking of up building my son's 26er Trek mtb, it's quite a nice old F&F made of True Temper, V/canti mounts only...

    Was wondering if I could get 27.5s in there, anyone got a ruler to hand to tell me what kind of fork/stays height from axles I'd need to get full mudguards & a medium width rim & tyre in there? The axle-crown on this fork is around 370mm... rear more like 360mm.

    Also: what're my options don't mind V or Canti) for rasing rim brake height from brake bosses position down at 26" level?

    Any help gratefully recieved.

    Will post progress once I've started assembling parts. The frame's a cracker! Thinking of dynamo, rack, touring set up, mabe compact drops or swept-backs, probably with bar-end or thumbie 8sp, maybe single ring as I have a pair of midbleburns doing nothing. Think the kid needs proper full length cranks, going to get rid of his hybrid style Isla soon.

  • Why 650b? surely the original 26" will be perfectly fine, and got lots of tyres choice.

    My sincere opinion is to stick with 26", it worth it if the frame take narrow 700c tyres, but since you got 26", make it less complicated by sticking with it.
