Short version: You probably can not fix it/convert to 8/9-speed for less than $150 even if you do not need to replace the chainrings.serval said:Short Version: Klein Pulse Comp with 7 gear rear casset looking to move up to 8 or 9 speed rear cassette because need to replace old worn parts (including the rear cassette, front cassette, chain, cables, front derailuer). Which parts should I get to make the change? Aim under $150 for all parts to make the change/update/replacement?
Chainrings, not a cassette. The "torn" or worn looking teeth are probably normal. They are contoured to shift easier. Does not mean your rings are not worn out and in need of replacing.Longer Version: So I have a worn Klein Pulse Comp (1996) and I think I need to replace some of the parts, some have already been replaced. I'm looking for recommendations of which parts to buy (and where if you like) to replace the following worn parts:
(1) The middle gear of the front cassette is sheared, by four of the gears the metal is torn between some of the gears. The top of some teeth are missing. The tops of some of the largest front gear teeth are also missing/knocked off.
If you convert to 8/9-speed you have to replace the rings and maybe the cranks, too.
No worries. the chain should be replaced often anyway.(2) The chain is an SRAM (I think) with a Power Link ... but the power link was improperly removed by a friend (punched out with a chain tool rather than removed w/o tools as it should be) and is prone to coming undone (usually when late for something important).
New cables and housing may fix it.(3) The front derailed is, well, funky ... it barely reached the largest gear and not because it's limited by the adjustment screw. It's physically hard to get it to shift up to the largest gear. After disassembaling and cleaning it's just barely okay to keep doing its job.
See #2(4) The rear cassette is a 7 gear version, not this new 8/9 speed stuff that has become the norm I suppose. I'm not sure my chain (SRAM with a power link) is compatible with this rear cassette, any ideas? Has worked okay for about 300 miles.
Replace the housings and cables.(5) My cables are dirty, loose at the ends, and the encasements around them, while doing okay, are probably also quite dirty inside.
To convert to 8/9-speed will you need to replace at least:So I want to replace these parts but I'm not sure what else I'll need ... if I change to the new 8/9 speed rear cassette, what will I need and which specific models/parts should I buy (new shifters at least, right?)?
- rear hub
- rear derailleur
- middle and large chainring
- cables and housing
- front derailleur
- bottom bracket
Not likely.I'm looking to do all this for under $150 if possible, so budget is a concern if you have recommendations.
Keep it as a 7-speed and you can fix it on budget.
New cassette, chain (not an 8/9-speed), cables and housing, maybe one or two chainrings and you should be good to go. You do not need 8 or 9-speed.
