Hi all this is my first real post to the forum, I have a black water FS canyon mountain bike my friends mother had given me to get out of her yard. Me being me I like to take things apart and put them back together. I test drove the bike up and down my street to get back inthe swing of things and tk test out the gears, yeah the gears on the crankset are pretth much shot popped the chain a coiple of times on the test drive a good amount of the teeth are knarled. So my question is what would be a good and cheap upgrade to the same size gears (48-38-28) I looked around on line and I see a few shimino that spark my intrest theyre lighter and they aee the same gears 48-38-28, I know whag I wantto get but the real issue is the bb does not look like it is threaded is is originally a single piece. Would I have to tap new thread into the bb to get some of the 2 piece cranksets in? Sorry if this has been discussed I did try searching for it

I can't find any specs for a "black water FS canyon mountain bike". What brand is it? What's the model? Or can you post close-up pics of the crankset & bottom bracket?

It would help if I could see a picture of your bike.

1. "Knarled" teeth on the crankset sprockets may be normal. Find a knarled tooth and check the opposite side of the sprocket. If you find a tooth that looks exactly the same, that's a shifting aid that's designed into the crankset.

2. If your bike has a one piece crank, the bottom bracket cups are pressed into the frame. If that's the case, it's possible to replace them with a pressed in adapter to install a euro-style bottom bracket, but the whole conversion might not be very cost effective.
