Lower BB on Uzzi...the easy way?

658 Views 8 Replies 6 Participants Last post by  hankthespacecowboy
Has anyone tried to just relace a 24" rim on back? That would effectively lower the BB quite a bit without changing the wheelbase for maybe $100-150. Anyone tried this yet? I'm sorta tempted, but, don't know how much the difference in ride quality would be from a 26" to a 24"? Anyone have experience on this or using a 24" rear wheel?

24" rear

I did this back in 2002 on my Large Bullit which I rode in my local trails.
I wanted a slacker feel because I felt I was "on top" of the bike. It sort of felt like a 45 pound XC bike (geometry wise).

So, I put a 24" rear wheel on it and the geometry was transformed! It felt great for taking drops and hitting steep DH sections of my local trails.

One issue though was pedaling. It just makes the bike much slower.
If you are putting miles in the saddle, don't bother with the 24.

If you are shuttling DH runs, the 24 rear could be an inexpensive way to change the way your bike feels.

Oh yeah...you may find some issues where your 24 won't roll over obstacles as easy as the 26.
I think there are posts on ride quality if you search hard enough.

good luck!

"supposely" ....yes supposely Intense is making the rear drop out for the M-3 that will lower the bottom bracket...if they start full production you might want to ask them about it.

Bottom Line call up Intense and ask them if they can make a drop out for your bike that will lower the bottom bracket

I figure my Uzzi will be at 64.5 - 65 deg. HA and ~14" BB with my Boxxer and 2.5 Minions... Should make for a great Keystone/Shuttle bike... it's currently 66 and 14.5, which I think works well, hopefully the new drops won't make it feel too slow.

A lower BB and slacker HA is going to make your bike feel faster.
I picked up a Rock Shox Peal for $200 in a slightly shorter stroke and it has made an amazing difference. The bb dropped by about inch, and the HA slacked out significantly. Running about 33% percent sag gives a much more "in the bike" feel - it is more nimble and more stable at the same time. I've still got about 6 inches of travel in the rear and have yet to bottom out the shock. I'm running a Domain 160 U-turn up front. It's great to crank down the front for dirt jump/4x style stuff, then have full extension for slopestyle/freeride/downhill. Don't think I would want to run a longer fork.
