my new to me gt arrette has an old (ugly altus c90 derailures), the jockey wheels feel rough even after taking them apart and greasing them
the front is an e type
can I just use a "clamp on" of the right diameter clamp (or with shims if needed) the seat post is a 26.8 so it would be a smaller size clamp
Would I need to remove the e type clamp?
Can I just cut it off with a dremel?
do I need to remove the BB?
the rear derailleur looks like it has a long hanger. "or maybe the pivot is not part of the hanger" it does bolt directly to the frame but the only current shimano that looks like this is the tourney
even the altus's hole look like it is shorter or the bole for the hanger is through the pivot. can the be used instead
or can I not see the pivot an I am only seeing the mount
