MTB-Idle in reply to @scultura

not quite. It does look short yes but that is the non-drive side (left) with the BB inserted the wrong way around (you can see the R on the BB sticker).

I'm assuming whichever cowboy did this bought a modern threaded BB and then realised that the frame is threaded the opposite way so just flipped the BB over.

undoubtedly this is leading to creaking on the drive side

the frame is threaded the opposite way

How the hell did that happen? Unless they've put a BSA BB in an Italian threaded frame. Which would be very loose and the wrong length

The numbers on the label indicate it’s ISO/BSA.

There’s no BB standard with a left hand threaded NDS, so my guess would be it’s been boshed in both sides with brute force.

(Or the frame was threaded the wrong way round…)
