SHIMANOAltus FC-M311 7/8 Speed Mountain for Bikes - Black

Fit well works perfectly

Bike shop said chain, wheelset, and cassette were worn, but wanted $250 for parts and labor. I already had the tools, done this exactly once before. Got everything I needed for under $80, just a matter of time (and park tools youtube channel) and my commuter is back and ready for the road. No chain guard, which is how it is described; if you are okay with that, the part is perfect.

lo malo que en la foto cuando lo vas a comprar aparece la guarda cubre cadena . y no lo trae

Bent the crank on my 1998 GT Palomar. It's a low end bike that I used for all types of riding. The bike really got punished when I took up MTB'ing and that's how I bent the crank. I bought a new Kona but wanted to keep the GT as a 2nd bike. I did not want to spend a ton of $$ upgrading the bike and the price of this crankset was right. Just wanted to make the bike rideable as least for non-MTB rides. After installing the crankset (needed to swap out the BB as well) I took it on the road and was very pleased with the ride and the smoothness of the shifting. This past week I took the bike on a few MTB rides and boy was I impressed! I was able to make climbs with the new crankset that I was never able to make before on this bike. The pedaling efficiency with the extra low gears was very noticeable and allowed me to keep my cadence high. I also love having the ring protector to prevent any damage to the chainring on any logrolls or jumps. In short, this was a GREAT upgrade to a low level hybrid bike. The only downside I see is that because the large ring is only 42 cogs the bike doesn't have those higher gears to really push on descents (road). But all-in-all, a great inexpensive upgrade.

First thing, BEWARE, the product you will receive is silver, not black like in the picture, till amazon updates the image, read product descriptions thoroughly. With all that being said, this is a fantastic shimano crankset. Installs easily, comes with new bolts too. The chainguard can easily be removed using a Philips head screwdriver.I bought this to replace an ageing and bent cyclone crankset and so far am not disappointed.Amazon offers an amazing deal, bike shops sell this for $45+, for that you can save money even with buying a crankset puller.
