strange temporary wheel build. will it hold?
 

The rear wheel on my daily rider broke 4 spokes in the last 2 weeks. I replaced them when they broke.
After all the bs I'm planning to get all new spokes and start over but I had a crazy idea for a temporary wheel.

I went digging threw my spare parts and found that the only extra 700 rim I have is a 20h and I also found that i have a 20h coaster brake hub. So I laced it up and trued it but I'm not sure if it will hold up ok and was looking for any thoughts on it. I have a front hand brake on the bike and use it more than the coaster so that might help

The rim is a Reynolds alta comp - deep v style rim
The hub is some unknown brand

If the wheel's well built, I don't see any reason why it shouldn't hold up fine.

Don't forget to secure the brake reaction arm well lest it get loose and wreak havoc on your frame.

This is like asking if your car will crash. It all depends on how the wheel was built (spoke tension evenness) and how you ride. Andy.

It's laces up and tention is very close all around.

Mostly I wondering is it will hold because I've never seen less than 32spoke coaster except on 16" and a few 20"
So the 20 spoke 700 coaster kind of makes me worry.

And no worries ill hook up the brake arm. The bike had a coaster to start with.

20 spoke 700c rear wheels are near the lower limit of what's workable, but they're made and succeed in the market, otherwise there wouldn't be 20h 700c rims.

While a coaster brake has the potential to create high torque loads in the wheel, it isn't great compared to the torque produced in hard sprinting or hill climbing. Braking torque is limited by the tire's skid traction, which because of weight transfer is usually less then the maximum possible driving torque.

Thanks this makes me feel better. I do use the coaster from time to time but I try not to do hard stops but some times I do.

I'm going to get a new tube (need one with a presta for this rim) in the next few days (when I get by the bike store) and get it on my bike see how it goes.

I rode on a 16h radially-laced front wheel for over a year. It was built on old 27" single-section Araya rim. Used it for training for over a year, put in over 10k miles and it only died because I rear-ended a parked car while oogling sorority chics playing volleyball on the beach...

Rear wheel does face more stress, I suspect you'll be fine if you've got optimum tension towards the high end of the recommended range for that rim.

Test---- Where you ogling enough that you knew which sorority?

I wouldn't go blazing down any winding downhills. I'm not a fan of low spoke count wheels, but then I'm a larger rider and ride some less than ideal rural roads. It might hold up OK for some general riding until you can get your other wheel reworked.

Thanks everybody.

I got a tube and put the tire on and rode easy about a mile. Didn't try the coaster out of fear that it tweak it. But seemed to ride ok.

I'm hopeing it will hold ok untill I get my other wheel fixed.

On a side note is it common that deep v style rims make a whistle/howl sound?
This wheel does it and so does the set on my other bike. Only seems to happen when cross wind hits just right.

Heh, heh... but of course!!! Well worth the road-rash and mangled equipment. I even posted some photos from a different ride past that same spot where I crashed here: Santa Barbara II Ride Report & Pics.
