mountain bikers

i am in need of some parts... i need a rear cassette for my mountain bike.. the bike is a 21 speed the one i have on there is wore out on the smaller dia sprockets and i just put a new chain today and it "jumps"....

i also could use a new rear derailleur is someone has one they don't need anymore... the ones on there are shimano...

I might have something in the "box of leftover stuff" in the garage, I'll root around out there and see if I can come up with something
You might also check the rear derailleur hanger, if they're even slightly out of true, the chain will jump or pop in the lower gears when you're really torquing the pedals

the guy at the bike shop told me the same thing... if you have one of those layin around it would help... *(i bought this bike for $150 ~3 years ago) it is a "iron horse" aluminum framed 26" mb i have put ~200 more into it *(90$ today for chain front crank assembly and brake pads)... its a nice bike... disk brakes etc... but i don't wanna put any more big money into it... i just wanna patch it one more time then when it dies the next time i will buy a new one.... *(saving now for above said new one)...

i really need to get into good shape again... i am strong as a ox but i don't have the stamina like i did pre 40... i rode 5 miles today and thought i was gonna die....lol.... on flat ground/city streets....

If you do mostly city commutes you may want to spring for some non-knobby tires. Makes all the difference in the world on streets. If you don't ride them down to the threads, you can transfer them to the next bike.

There is a decent motobecane on Ebay. Brand new old stock stuff. For 600 bones you would be rolling with 27spd with a mountain mix of components including an XTR der and a SID fork. Those two parts alone are worth the price of the bike.

With a new chain you really want a new cassette and probably a new small front and maybe a new middle front. The chain and sprockets sort of wear together and you'll have some problems replacing any one piece without the others. I have lots of worn out sprockets but they won't help you with a new chain.

Trust me. I've been into mountain bikes for ~20 years. Have you checked Nashbar? They often have decent store brand stuff for older bikes for cheap prices.

Check out this website. They are a great place to deal with and the website has just about everything under the sun. Plus, they have new Shimano cassettes starting at $18. The altus isn't listed and I don't know where it falls in the quality.

I use performancebikes and greenfishsports when I order online. I use JensonUSA every now and then. Nashbar is decent, but never seem to have what i want.

I let the bike shop talk me into a new chain early this fall.
One ride with a new chain & old chainrings / rear cassette had the chain skippin' so bad on climbs that I picked up the whole bike & threw it at a tree in a fit of rage ...
Now, in addition to the new chain, I also have a new rear cassette, a newer rear derailleur (a take-off I bought from the shop mechanic for $10) AND a whole new rear wheel since the old one sustained an irrepairable bend to the rim.

Go to nashbar or performance. The stuff you need is pretty common and cheap if you shop around. The other trick is the tool you need to actually change the cassette. Local bike shop may loan tool & let you do the work. If your derailer hanger is straight, leave it alone. I have the same Ironhorse frame you have (betting) as a back up bike. If the hanger is bent just use a big crescent wrench and tweak it back. It will move a little but too much will crack it. As far as the derailer goes if it's just dirty take it off ,scrub it good (soak it in simple green for an hour) then scrub it. Check all the derailer pivots. If you have no slop in pivots the part should still be good. As mentioned by the others it is a good idea to replace chain with new cassette.

Oh yea. unless you are a racer you dont's need XTR, or even XT. Old LX works just fine if you keep it clean and adjusted. These are levels of Shimano components. Good luck.

thanks... hopefully the new cassette will be in monday... i am on pretty good terms with the local bike shop.. i already have a new chain on there *(which is what started the popping).... i had to replace the front crank assembly because zack had gotten hit by a car on this bike *(low speed) and it bent the frt sprockets just enough to make life miserable....

anyway now i have new front crank assm new chain new disk brake caliper and cassettes on the way........

now all i need is a new front fork and i have a new bike... ...lol... btw fork is NOT bent it either needs rebuild or replace because its not made for someone my size/weight...

matt *(local bike store owner and all around good/trustworthy guy) said rear derailluer has a bit of slop in it but will still work fine unless i really want ultra precission shifts... *(remember it will be a city bike and most the time i will ride around the local cemetary *2.5 miles per revolution all paved*..

i really do appreciate all you guys quick answers... as usually wt's are the best...

Not sure what type of "headset" is on your bike (threaded or not). Check this out. Nashbar Rigid Mountain Fork, Part #NS-CMF $59.00. This would work great for your type of use.

Yes, a picture will help.

It will more than likely be a 1 1/8" headset.... and most are "Threadless" but some intro models are still threaded.

The difference at a glance... can you put a wrench on it and tighten it? If the asnswer is threaded.

Ok, that looks to be a threadless system or what has been referred to as "Aheadset". Right where those ring spacers are below your stem a threaded system would have a big nut. I believe the fork mentioned in previous post will work.

U are right. No mountains here...I always have to correct myself and try to call this "All terrain bicycling". I did however grow up in western PA. Have ridden the Black Hills, Winter Park, Buena Vista, West Virginia as well as numerous other places on Mountain Bike to include the cobbles of Belgium. All offer a distinct challenge, some with great beer after the ride.
