I'm trying to rehab my nephew's 8-speed Mongoose & I think that the front derailleur is bent. I noticed that while shifting the front der moves up & over which didn't seem right. On my bikes it's moves left or right. The housing where the adjustment screws are located seems like the 2 halfs don't meet exactly. The componets are Mongoose TD-Pro so I imagine that their not the best quality. I'm wondering if the frt der is hosed, can I replace it with Shimano & leave the rear der & shifters alone (for now). Also, is a 9speed frt der an option?
With regard to upgrading to 9-speed, this bike has an 8-speed freewheel. Would a rear wheel rebuild/replacement be required?
The last item concerns replacing the rear der. Do you have to replace the shifters with the rear der? Thanks in advance & have fun riding!!
