    Kinlin XR-300, Wheelbuilder says I'm too light.

    Preface: 5'8", ~150lbs

    I'm looking for some new wheels now that one of my stock shimano RS-10s on my CAAD9 looks like a taco shell from a recent mishap. I asked a wheel builder for suggestions on a new set of Kinlins with a PT. He/she says that the XR-300 is overkill for my weight and suggested I look into the XR-270 for weight savings, while preserving aerodynamics. Opinions?


    P.S. Psimet, please answer my email. I would like the opportunity to give money to you.

    Either XR-270 or XR-300 will work for you. How many spokes are you planning on using? There is nothing wrong with overbuilding a wheel, you just don't want it underbuilt.

    The xr300 is 3mm deeper and 20g heavier. Frankly the aero/weight tradeoff is close enough that it probably doesn't make a heck of a lot of difference which one you get. They are close enough that I'm not even sure why they make two different rims that similar. Seems an odd thing to really have a strong preference about. Maybe Rob could expand on that though.

    Too light? I just got my Psimet wheelset, built with the XR-300 front and rear. I'm 5'5" and 125 lbs. They're great. I have no idea what could possibly be problematic about a 150 lb person riding those rims.

    How can you ever be too light for a wheel? I have Kinlin XR200s and weigh 136 pounds, btw.

    Yeah, there isn't such thing as too light. It's true that you can get away with a pretty low spoke count on those, and the XR-270 would save you some weight, but if you want XR-300, this guy shouldn't turn you down on it either.

    either rim will do for you.
    at your weight, you can go with 20/24 with XR-300 or 24/28 with the XR-270.
    Food for thought: if you aren't dead by 2050, you and your entire family will be within a few years from starvation. Now that is a cruel gift to leave for your offspring. ;)

    Find a new wheel builder.

    Some sort of pithy irrelevant one-liner should go here.

    I'm taller than you, lighter than you, and I ride 300s.
    This isn't a problem, either I'm missing part of the conversation between you and your wheelbuilder, or you should find yourself a new wheelbuilder (and it looks like you have good taste :-)

    Which would make the difference in weight basically a wash, or even tilted in favor of the XR-300. But I don't think the 270 would require an increased spoke count.

    You can always drop the tire psi a few pounds from your usual setting if the XR-300 proves to be stiffer than you need, if that's what the builder is concerned about.

    It really depends on what you want out of these wheels. If you're looking for the lightest possible build, then yes, the 300's are overkill. FWIW, I am 190 lbs and have been riding with the 32 spoke xr-200's for a couple seasons now.

    It's safe to say that the phrase "too light" should not enter a cyclists vocabulary. Unless you are Andy Schleck. Otherwise you are too heavy.

    I don't know if Psimet got back to you or not, but I believe on his website he says Kinlan rims vary in weight and he has measured enough 270s that weighed more than 300s that he would not recommend 270s just for weight savings.

    Doing some quotes tonight - pm me the email address you used

    FWIW - 270-300 they are honestly so close it's kind of sad. The 270 is usually a little lighter. Not much of a difference. To say that one is "too light" for a 300 is a little silly.

    Common you people! Would you have this guy get a wheel set that is tandem rated? There is no reason to overbuild a wheel, just as there is no reason to underbuild either. Build it for what you are going to use it for.

    Oh dear God tell me you're talking about something other than the difference between a 270 and a 300. A 300 is hardly "tandem rated". Pull out a ruler and look at 3 mm in real life. It's not like someone was recommending going to a B43 rim.....geez....

    Rob, just out of curiosity do you have any idea why Kinlin makes both the 270 and 300? It seems so redundant...
