Hey all,

After 2+ years of flawless service my 150mm 34.9mm KS Lev Integra finally gave up on me and needs a rebuild. Plan on doing that and either keeping as a spare or selling as I'd like to get back up and running more quickly and also use the opportunity for a possible weight improvement.

I was planning on going with a KS Lev CI as I had good luck with the Integra, but was also considering Bikeyoke given all the great reviews. That said, neither is offered in a 34.9mm diameter, so I would have to shim my seat tube.

Couple questions relating to that:

1 - No worries with a quality shim and proper torque correct?
2 - Anyone have experience with smaller diameter posts offering reduced reliability?

If reliability isn't notably reduced I would probably go smaller (30.9 vs 31.6) just because of some (minimal) additional weight savings and flex for my stiffass carbon Honzo. Plus I figure I won't find myself with a new frame that has a 30.9 tube that my 31.6 dropper doesn't fit in.

Any big flaws to this logic?

Appreciate any thoughts,

Chase

I used a problemsolver shim on my carbon frame. 31.6 shimmed down to 30.9 with no issues. If carbon frame just remeber carbon fiber paste

BikeYoke does have the Revive MAX with 34.9mm, and 125/160/185mm drop.

Also, you can swap the lowers between the 30.9 and the 31.6 versions on the Revive. You just need to get the new lower you want and swap them.

Some manufacturers might void the warranty, if I’m not mistaken.
