converting non-interchangeability crank into interchangeability?
 

Someone know a way to convert non-interchangeability crank into interchangeability for shimano FC-TS38? http://bikeforums.net/attachment.php...hmentid=352989http://bikeforums.net/attachment.php...hmentid=352992

need a 44T for nexus 7 and I like the arms desingn and I use with them...

thanks

You can't do it. That crank has the chainrings spot-welded in place and there is no practical way to remove them non-destructively and, even if you did cut them off, standard bolt-on chainrings won't mate up with that spider. You need a different crank.

thank you for the answer.

Along with another crank, you'll likely need a new bottom bracket. Even if the new crank is also square-taper, the existing bottom bracket spindle length is likely to be different.

that's not a good news for sure... hopefully will work with the one I have, if not i'll buy second hand both cranks and bottom bracket.

It keeps getting harder.

Since you're buying a second hand crankset I was going to say just try to buy the bottom bracket that originally came with it. Unfortunately there are two common bottom bracket shell widths so you have to find the one that matches your bike frame.

Everything on a bicycle works together so it's rare to be able to replace just one component without having to do something else to make it work.

thanks for clue
