Hoping Im posting in correct area. New to posting in general. I sincerely apologize if I'm doing this wrong. I have a Lemond Classic Revmaster Spin Bike that i bought off Craigslist for $300 when I lived in NV back in 2008. The right crank arm is broken and needs to be replaced. My pedal broke off mid spin . It either needs to be re-threaded (i think) or I need to purchase a new right crank arm. Both cost approximately the same - around $125+ plus $12 shipping. I'm in Northern California. My question is, does anyone know anyone in the Northern California area that would have a right crank arm spare part for cheaper or anything I can do to repair this one for cheaper? My 9 year old son and I like to spin together for exercise (he spins on our $120 awesome spin bike from Fry's Electronics we bought a few years ago - hard to believe that the Lemond crank arm is more expensive than his bike!) (right now we are just taking turns til we can get a crank arm for the Lemond)

Thanks! Kari

You're not clear, but if the issue is simply that the pedal mounting thread is stripped, then repairing (if possible) shouldn't be that pricey.

There are threaded inserts that can be fitted, but they require retapping the stripped hole oversize to accommodate them. Not all damaged arms can be repaired this way, it depends on the arm itself, and the nature and extent of the damage. But IF it can be repaired this way, I'd expect it cost something in the range of $25.00 or so.

Look for a bike co-op (aka bike kitchen), and bring them either the whole bike if you can, or at least a good closeup photo of the damage. (take a bunch from different angles). If you can't bring the arm, you might be able to arrange a house call for an additional fee, but it still shouldn't be that costly (if it can be repaired this way).

BTW- if dragging this around isn't practical, call a few shops and co-ops and ask for a rough estimate of the cost of fitting a "helicoil" or thread insert into the right crank. Of course it's rough working blind, and may not even be possible, but at least this will help you create a short list of shops you might bring it in to.

I did a Google search and came up with a picture of that "bike". The right side crank appears to be a special item unique to the design and can't be replaced with any standard crank so if the arm is broken an OEM part is probably the only fix. If it's only a stripped pedal thread, the arm looks like that should be repairable with a "Heli-coil" type of thread insert and many bike shops are equipped to do this.

I took a look, and according to the maintenance instructions, you can remove the crank arm with a couple of allen keys and a standard bicycle crank puller. You will need to do that to replace it anyway, so I would suggest getting (or borrowing) a crank puller, and remove the crank arm to bring it to a coop or shop.

The bottom bracket used doesn't look standard to me, probably so that it limits the possibilities of finding a replacement elsewhere, or you could be able to look at other possible replacements.

I found different photos, where it seems to be a standard 5 pin aluminum crank arm (the rest is unique) and if so it's replaceable with something you might match from the used crank bin at a co-op. In any case, if it's an aluminum crank as it appears to be, it's usually repairable with an insert, and this could be done in your home, saving you the effort of hauling it to a shop if that's an issue.

One of the places you might try is the bike kitchen in Sacramento. One of their volunteer/staffers is Mike Larmer who is a regular on this forum. I know they fit inserts on a regular basis (or used to) and I'm sure Mike or someone else there has the skills and knowledge to do this within budget constraints.

That's only one possibility which you can use for a base line, depending on where you live, I'm pretty sure you can find someone comparable much closer to home.

I have one of these bikes, too. The cranks are proprietary, yes, but as others have said, you can shoot a helicoil into it pretty cheap. The company's website has every part available to order, if it comes down to that.
