Can these wheels handle a Load...(10 posts)

Can these wheels handle a Load...t-moore

At 6'4" 245lbs, can I put 200 miles per week on these wheels. Or will I kill'em....

revos are a bad idea for you.collinsc

I have no idea what it is like being 245 lbs, but I wouldn't do the revos.

You might hear suggestions for 36 holes.

Otherwise, thats basically the defacto standard training wheel suggestion around here.

I'm 6'0" 240 lbs. and ride on Open Pro's with 14-15 db DT spokes, laced 3 cross, 32 hole. The only trouble I've had is when I hit a small speed bump a little too hard with the back rim, now I have the well documented "click" from the rear open pro. This can easily be fixed as you can read about in the review section here on the site. The other rim I'd suggest is the Mavic CXP 33. A litle heavier but as strong as an Open Pro and more aero.

P.S. Big guys belong on brass nipples instead of aluminum,IMHO. The weight gain is negligable.

Good luck, Bob

The wheel as built would be ok up to 200 maybe 210#. Over that you may have problems. As the previous poster mentioned, go to 36 spokes in the back at a minimum.

Best idea would be to go to 36 spokes front and rear. Theory suggest the combined DT Rev spokes in the front and non-drive side would be ok. But some practioners would go DT Competition double butted all way round.

I have heard some wheel builders that specialize in wheels for heavy people going to Sapim Cx-Ray spokes. These spokes are very expensive, adding about $200 to the price of a set of wheels. They are known to be very, very strong though. These spokes are hard to find in the US. Some wheel builders, notably zip use them on their wheels and they do make wheels for 'clydesdale's'.

I did hear from one wheel builder in the UK that was having a problem with a customer that was 260+#. He was always braking spokes. The builder switched to the CX-Ray and the problem disappeared.

Spokes are only one component of a good wheel. The strength of the rim and skill of the builder are probably more important. Also I have noted that wheel builders like certain spokes and are reluctant to change spoke brands. Building with fancy spokes introduces new issues for a builder. It is probably best to avoid getting a 'DT' builder to try something different.

I think you will also find that some wheel builders will suggest that the OpenPro rim may not be as strong as you need. A lot of it will come down to how easy or hard you are on your equipment. Smooth roads and an easy touch will be easier on the wheels than the typical roads we find in NA.

Best suggestion would be to find a wheel builder that will give you a 2 year warranty on the build. I also suggest that you look at www.peterwhitecycles.com . He offers a lifetime warranty on his wheels and will only build something that will work.
stouter build advisable...C-40

Kind of silly for someone who weighs 245 to worry about a few ounces of weight. The front wheel might be OK, but the back should not include any 14/17 spokes. I would also not use alloy nips. Trivial weight savings and much greater risk of failure. These are training wheels. Better for them to be stout than light. As others mentioned, a stouter rim like a CXP-33 would also be advisable. It should be able to handle higher spoke tension. A high spoke tension is required to avoid detensioning the spokes under a heavy load.

I would go with the CXP 33's, 36 hole back, 32 on the front. 14/15 double butted on the spokes. I am on CXP's (188lbs) 32 hole and have really enjoyed them. They have stayed true as can be. I dont really see them in the catalogs like other wheels.

32hole 3X 14Ga straights laced to Velocity Aeroheads. I'm 6'4, 230 in season and ride 3000 miles a year on these. They are simply reliable and quite reasonably priced from Colorado Cyclist. I never have wheel problems in the 2 1/2 seasons on these. I did on my Open Pro's laced to 105's with the same spoke. Those kept breaking spokes at the hub flange end after 6 months of riding.

Simliar wheels on the MTB (XThub 3X to Aeroheat) and those have 4 years.

I built up a front 32 hole 3x Open SUP rims with 15/16ga spokes a few years ago... JRA it was fine, but sprinting on it made me realize that it wasn't the stiffest wheel around. It almost but not quite rubbed the brakes when sprinting ...and I weigh 60# less than you do!

MY $.02: Stick with 14/15 butted spokes the whole way 'round, brass nipples, and stay 3x.

If you ride lightly on your wheels, you may be OK with the 32 hole rear wheel, but for your weight, I'd go 36 spokes in the rear.

Once (if) you ever get to the 200# range, THEN start looking for lighter wheels.
