I have a 21 speed (3 front, 7 rear) NEXT bicycle ( model number 8568-49, year 2007.12.06) sitting in my back yard at the moment a few missing parts and I was hoping to get some help on what to get and whats compatible with what because my knowledge of bicycles is limited. Ok so here it is...
Bent rear axle 3/8 thread 165mm... I found it hard to find a 165mm would a 170 or 175mm be alright?
Missing rear derailleur... I no model number to go off of here so I was thinking a Shimano Tourney SIS TY22? The cassette is a 7 speed Shimano MF-T207 and the front derailleur is a Shimano FD TY18.
The twist shifters are bad I noticed they were SRAM so here I though... SRAM MRX Twist Shifters? Will they work with what I have and what I'm proposing in terms of derailleurs?
And finally chain, here I have no clue... something that wont snap as soon as I start to peddle.
I'm looking to complete my bike and hope to enjoy in soon, I'm very open to suggesting and thank you for any help.
