Crank Arms Only?(8 posts)

Crank Arms Only?Tarzan
Sep 14, 2001 9:40 PM
Can I purchase crank arms separately? I have a 175 RSX triple and believe that, at 5'3" with a 28" inseam, I should have 165. Occasionally, I get pains in the front of my knees and with a compact frame with 700C wheels, I also experience toe/wheel overlap. BUT, I do do a lot of hill climbing. Do you agree I should go for the 165's? Is it possible to buy just the crank arms or do you have to buy the whole crank set? Where might I be able to get these? Thanks!

I know you can get Campy arms, I would assume you could Shimano also.

It's more expensive than just buying a new crankset. Check the prices here at Branford Bike and you'll see what I mean.

I'm suprised your bike was assembled with 175mm cranks. Smaller frames normally come with 165mm cranks, so it sounds like yours got swapped at some point prior to your buying it.

Your LBS will be able to get a new RSX crankset for you, but it might be cheaper for you to get a 105 or Ultegra crankset via mail order and pay your LBS to install it if you can't perform the work yourself. Excel has good prices and service.

Thanks for the quick reply. I discovered after I posted my message that crank arms only were available but were just as costly as the whole set. Go figure!! You're very right about the shop making a mistake. I bought this bike used from them and I didn't even notice the crank arm length until I had it for several months. When I approached the shop about it, they just shrugged their shoulders and said, "Hey, you got more power with 175's." Needless to say, I am a little perturbed by their unsensitive approach. Unfortunately, being on Maui, I have little options. Thanks again.

So any statements the shop might make are largely irrelevant. You may want to evaluate their labor cost versus the cost of buying a crank puller and a pedal wrench and doing the work of installing the new crankset yourself. Me, I have a tool fetish...

Yep! I have some tools so we'll see. Thanks!

check here for prices of individual crank arms.

i agree with the other posters that a new crankset might be the best way to go. if your chain rings are anywhere near replacement time you will come out ahead when you add the cost of cranks+rings. also check the classified and ebay. tons of good used cranks out there. good luck

Thanks for the link to The Third Hand. I checked 'em out. Their prices are better but didn't find any triples or even anything smaller than 170. Am I reading it wrong?
