- 27.5 Forks on 26 Frame
Thinking of upgrading forks onmy Cotic Rocket 26 from 150mm revs to 160mm Lyrics.Posted 2 years ago
If I try to future proof a little by going 27.5 will this lower the bb even more than just with the extra fork length?
You’re Axle to Crown height is going to increase by at least 40mm, possibly upto 70mm) as the Lyricks, for a similar travel, have a longer A2C. Moving to a 650b will add around 20mm A2C on it’s own. You’re likely to raise your BB height by 20-30mm.Posted 2 years ago
Surely if you go longer and 27.7 you’ll be raising the BB and slackening the head angle?
I run 160mm forks on my 26″ Rocket and they’re fine; I reckon the extra height from the 27.5 forks won’t make too much difference over that.

I’ve got some brand new Lyrik R 26 forks you can have for £250 posted.
See classifieds if interested.Posted 2 years ago
Whats the offset on the new lyriks?Posted 2 years ago
As others have pointed out, fitting longer forks will lift your bottom bracket. I don’t know how feasible it is to fit an offset bushing to compensate, but even then you may end up with a taller BB than you started out with.Posted 2 years ago

makes very little differencePosted 2 years ago
When I looked (Pikes rather than Lyriks though) going from 26 to 27.5 only changed A-C by 10mm i.e A-C on a 140mm 27.5 Pike was the same as on a 150mm 26″ fork.Posted 2 years ago
