    carbon wheelset weight limits...

    hey guys!

    well i guess i belong to the clydesdale class...i am 6'3 and 215 pounds.

    I ride road bikes every weekend with the wife, we've been averaging 30 miles each ride but trying to gradually increase for a Metric Century ride coming up in August.


    Anywho, i am building up a titanium road frameset because we both love riding and have gradually become more and more into going on long rides and doing more organized rides...maybe even races down the line.

    I am looking into some carbon wheelsets, and this is where my question lies for the heavier road cyclists out there like me:
    How strict is the weight limit for some carbon wheelsets? because i notice quite a few have a 200 pound weight limit. is it instant death if i ride a 200 pound weight limit carbon wheelset? or should i be fine? actual experience is what im looking for...

    or are there carbon wheelsets out there made for larger riders? basically i want a light weight wheelset with a taller profile rim for aerodynamics


    ok any help is appreciated! thanks

    Seen plenty of them with 230 too...pretty sure I just read the zipp page and they were 220 or 230. Pro wheel builder dot com lets you put in your weight and it will suggest rims based on that

    So there are plenty of choices if you really want carbon at your weight.

    Some of the bigger carbon wheel makers have some input in this article. The notable exception from the article is Zipp who have clearly posted weight limits and also sell clydesdale versions of some of their more popular wheels.

    Edit: I just noticed that Zipp did away with the clydesdale version of their wheels but the firecrest shaped wheels have higher weight limits than the standard non firecrest shaped ones.

    The 303 fire rest are rated at 225 and the 404 fire crest at 250

    I'd give two thumbs up to Mad Fiber wheelsets. No weight limit. Utilizing the tensile strength of carbon into the whole structure of the wheel. So sweet. Best wheelset i've owned.

    Carbon wheels seem to be very expensive. Is the performance difference really that drastic to warrant spending over $1000 on wheels? Not trying to crap on anyone, just honestly curious. I've never ridden a bike with carbon wheels.

    Deep cross-section (>50mm) wheels provide a noticeable benefit when trying to maintain speeds in excess of 18-20mph. Whether the benefit is worth spending $1000+ probably depends on how much money you have in your wallet and which race you're trying to win...

    It depends on what you expect out of them. They have a couple of advantages over regular wheels
    1st. They faster than regular wheels. The faster you go, the bigger the advantage. Speed benefits below 20mph+/- are negligible. The deeper the rim depth the more benefit you get. The table below will give you an idea of the wattage/drag differences of various wheels (at 30mph). It's from 2007 but it'll give you a good idea. I don't have numbers for std. box section rims with 32+/- spokes but I would imagine they are higher. I took out a bunch in the middle for brevity.
    Not all aero wheels are created equal: You can see the whole test at this link

    2nd. The deep section rims tend to make for stronger wheels for obvious reasons. My Zipp 404's are 18 spoke wheels and have held up under my fat butt since 2006.

    3rd, they can be made very light which greatly improves how your bike handles and overall ride quality.

    Finally, they aren't magic and they aren't going to make you the next TDF champion (that's what steroids are for) but, if getting the maximum aerodynamic advantage with minimum weight is your goal, then a carbon fibre wheel will likely be a good choice for you, just as it is for most professional cyclists and triathletes.
    It doesn't get harder, you just go slower.
