Anybody know about bike cranksets?
I want to change the gearing on my bike to raise the gear rations up. I know very little about bike mechanics and was hoping someone can clear some questions up for me. Its a Trek Hybrid, currently stock 48/38/28 crank on it with 13/34 7 speed cassette. I want to put a 52 or bigger crank on it in the low to mid 50s if its possible.
1. Is this something I can do myself having little background knowledge or would i have to pay a shop to do it? Are there compatibility issues i need to worry about, or are they pretty universal (do i just buy any old crank, pop the old one off and the new one on?)
2. Will I need a new front deraillur? do you have to adjustments on the current one? the stock is a Shimano C102 right now
3. anything else I should know about doing this?
Alright… Looks to me like you are looking to put a road crank on the bike.
If you want to do it at home, you’ll need a crank puller, and BB tool if you want to go to a two piece crank. The shop will most likely install it with purchase. A new crankset will almost certainly be cheaper than replacing each of the rings on your current crank set. If you replace just one ring (outer), your gear ratio’s will be nuts…
You will need to adjust the fr derailler, but not replace it.
Again, because of the required tools, and adjustments, I’d just bring it into a shop.
