I'm building up an old RC200 F2 frame which has sat in my shed for several years into a more road going bike in preparation for this years Dartmoor Classic ride in the summer and bought some lighter wheels to suit which came off of Ebay in new condition with Tiagra hubs on Mavic 717 rims with skinny Schwalbe slicks - all looked great until today I offered them up to the frame and then discovered the rear axle ends weren't even touching the sides of the dropouts. :?
Now I've found out that the Tiagra hubs are 130mm OD which is normal for a road hub but MTB frames are typically spaced for 135mm axles - :facepalm: !
However on measuring the gap it seems my Pace has a 140mm width and I don't fancy an aluminium frame can be persuaded that far without serious issue :shock:
I'm hoping I can get a replacement Shimano axle (146mm seems the common part) and simply replace the short one in the rear hub and then use a few spacers but this will only leave 2~3mm of axle end for each side.
Is that safe ? And why has my frame got such what seems to be an odd size - did Pace make them in this spec - and how best to fix this problem ?
Thanks.
