Well, i need some lightweight alloy/carbon cranks -don't ask why
-ok for a micro bmx
-found some square taper 125mm -but steel and heavy -correct length tho
-anyway question, these hollow tech cranks -are the threaded bosses pressed in under a few tonnes?
-are they infact a boss pressed in? considering they are 'hollow'?
-ie can i get the threaded bosse, re-drill the cranks and press them in
-cos i have tried cutting down and re threading a few sets of cranks now, to no avail, heck, i even did a set and tapped them for a oversize helicoil -got the threads the right way around, they looked nice and straight, -BUT i then could't get the lh threaded helicoil
🙂
-oh well -
-the next set came out bad, then i gave up
are there 125mm alloy cranks available - off the shelf?
😄
