I built a new SolarisMax a couple of months ago & the new 1x Shimano crankset seemed really tight to fit through the external Shimano BB. The BB is from my previous bike & its cranks went through it easily, the BB is still in good nick. On the Solaris it needed some big wallops with a mallet to get the shaft all the way in & also to remove them. I've just started to replace the 1x crankset with a new 2x crankset & it is tight too, the last 12mm or so, so maybe not quite as tight as the first crankset but I've not forced it in fully yet.
Is a tight BB a sign of the BB needing faced maybe?
Thanks.
Pretty normal to have to whack them through with a mallet ime, think it might even mention it in the manual
A bit of a tap seems OK, but the first crankset in the Solaris seemed to take excessive wallops than any other I've installed.
Thanks, I'll have a look for a manual.
I've just taken the cups out & they are tight on the axle still. So nothing to do with the frame.
I've also tried pushing a spare new BB onto the shaft, and it was even tighter. Immediately at the end of the splines there's a step in the shaft diameter making it tight.
Mallet time it is then.
Do you still have the old cranks, just to see if they offer up as they did when the BB was in your old frame? I must say, when I read your OP the first thing that sprang to mind was BB squareness.
No, I sold the old crankset & the old frame. I've only got the old BB, plus two new cranksets & a new BB also. The old 3x crankset was pretty old though, so maybe it had gotten slacker through the years.
I distorted a centre tube assembling a BB and it caused a similar problem.
The centre tube isn't distorted. I've booked the frame in to get the BB faced next week.
