I bought this item to put it on my vintage italien "Alpes" bike.I have chosen spindle lenght of only 115 mm. in order to bring front crank chainrings 42/34/24, as much in line with rear Freewheel(14-28T 6 speed) as possible.I must say that my bike, built in 1958 was monospeed one and I did not want to "kill" it, since it was part of my childhood memories.That means frame was not designed to accept easily all this modification.
But everything went well, ShimanoBB-UN55 BottomBracket 70 x 115 Italien thread (36 mm)with alloy left cup, fitted
perfectly.Both threads, left and right side are right hand ones.
I could have bought 118 mm. spindle instead of 115, wouldn't be any worse.Front 3 speed derailleur only had to be adjusted properly to new position of the crank.
Now, it works perfectly with no chain noise at all, shifting runs smoothly too.
So far I have made only 100 km, but it seems to me that this bottom bracket and entire system could last for ever, or at least another 5o years!Very happy.
