Sram Red BB386 Crankset with BB386 Bottom Bracket in BB386 Frame: Small Chainring touches Frame
Posted: Wed Jul 19, 2017 11:22 pm
Good evening,
I just got my new Red (eTap) Crankset which I ordered in the BB386 version (00.6118.446.002) because I have a BB386 Frameset (the new Lightweight Urgestalt Disc) and I also got a Kogel Bearings 30mm Bottom Bracket for BB386 Framesets.
So far so good - the Crankset does come with a wavy washer & a slightly thicker (maybe 3mm), black spacer on the non-drive side and an extra one of that 'thicker'/black spacer in the box (and also 2 or 3 of the very thin transparent washers).
Initially I just tried installing the crankset as is - meaning keeping that wavy washer + spacer on the non-drive side, stick it through the BB and place the drive side crank on, and tighten the bolt to the 54nm.
Now the thing is - one of the screw-heads of the smaller chainring rubs against the frame slightly, but noticeably.. which is obviously not a good thing
I double-checked the Sram installation manual (https://sram-cdn-pull-zone-gsdesign.net ... ackets.pdf) but it unfortunately has no extra entry for the BB386 version I have.. so I was wondering what's wrong & what to do?
Intuitively I'd try either sticking the extra black spacer or 2-3 of the transparent washers on the drive side.. but is that the right thing to do? And if not.. what would be?
I also double-checked whether the BB shells are flush & properly pressed in (which they are), whether the chainring-bolt(s) are tight (which they are) and the entire crankset has no wiggly play when tightened - but is it ok / the right thing to do here to simply stick on the spacer/washer on the drive side to get enough distance between the bolt/screw-head and the frame?
Cheers and thanks for any advice!
