Urgent! Shimano RX100 won't fit on UN54!
On my friend's Bertoni road bike, I replaced a Stronglight bottom bracket with a Shimano UN54 (70x113), thinking that the Shimano RX100 crankset that I bought would fit.
It doesn't seem to fit properly. Unlike the other bike I put together, the right crank does not go all the way in the BB shaft and the left crank doesn't seem to go in as much either.
None of the bike shops around carry Italian bottom brackets, so I would have to order it. My friend is leaving on Friday, so I would have to order the right one ASAP.
Edit: I double checked and tried to make it work. It seems to work, but ---> see bolded sentence above.
The problem was that the crank did not go in far enough for room to shift to the big chainring.
