Im putting together my old morewood shova for the mrs, buying one of those £16 deore ST cranksets off of chainreaction and now coming to look at the bb.
what size spindle will i be looking at I'm assuming 73 shell 113mm spindle would give me 50mm chainline..but not sure...?

anyone shed any light on that please?

@IHN i found this [url= http://techdocs.shimano.com/media/techdocs/content/cycle/SI/FC/SI-0086A-001/SI-0086A-001-ENG_v1_m56577569830657937.pdf ]pdf here[/url]

which i think has the info on it but its not too clear, by the look of it i need a UN26-E 113mm to give me a 50mm chainline (which im assuming is right for the frame as i can't find any details anywhere!!)

so after all that i reckon the UN55 crc have in a 73mm x 113mm spindle should be ok........

i hope.

Smashing, ta.

Actually, how do I know what chainline I need? I'm assuming it's 50mm, but how can I be sure?

you'll need to check the frame manufacturers data, i can't find any on my morewood, as they no longer do any archive data...so im guessing !
