    1.9 tire on narrow rim

    Just got in the 16" kinlin rims I'd ordered off aliexpress and I guess I should have asked for more specs.

    Got them in and they're a lot more narrow than I'd hoped. Internal width is 13mm, external width is 19mm.

    How much chance is there of these working with a 1.9 tire?

    How much does the rider weigh? Generally with kids bikes it's not going to greatly impact their experience because they don't weigh much.

    The biggest down side to me is that you'll have less room to work with when mounting the tire and trying to squeeze a 2.0 tube in a small rim space that is smaller than modern road bike rims. Other than that you'll probably be ok but more details about the application would help.

    Stop asking how much it weighs and just go ride it.

    He's about 40-45lbs.

    Rims are 24h and I bought a 24h hub.

    Working on a disc wheel for a Yoji 16 that I'm putting a 20" air fork on.

    I had considered trying tubeless: would that help or hurt the situation?

    As a note, I haven't bought spokes or built up the wheel yet. Trying to save time / effort before taking the step of building it myself or having the local bmx shop build it only to find that it doesn't work.

    Just a little discouraging since I already went down the rabbit hole of ordering vbrake adapters that turned out to be too small for the fork.

    Ah custom builds, they always go together the first time with no problems. You must be doing it wrong. (sorry, I had to)

    Anyone under 50 lbs isn't going to stress the rim/tire hard enough to make a difference in ride quality or rider experience.

    Would a wider rim be slightly easier to work with? Yeah. Is it worth it to you to source another rim? Up to you?

    I've never tried one that narrow. I'd think tubeless would help as you wound have to wedge a tube in there.

    If I could find a wider 24h 16" rim, I'd be willing to give it a try. So far I haven't had much luck.

    I don't know much about 16" rim options. Maybe try calling spawn or flow? This place had a 18.4mm id rim listed and will drill however many holes you want.

    Those are 349 rims (the other 16" size). Carbon also drives up the cost enough that I'd almost be tempted to just get a 20" disc wheelset and see how well a 16/20 pairing worked.

    Spawn is using 16h rims and Flow is using 36h rims for their 16" bikes.

    I have the current wheel from the Yoji, so that's an option if I were to shell out for another 32h hub. Had hoped to keep that stock in case I wanted to go back later, though.

    I also have some 20h rims from a jogging stroller, which would require either a different hub or some really odd lacing.

    Youll be fine I think. I got a Spawn loam star 16" onto an Islabike rim.

    Oh got it, didn't know there were different 16" sizes. Is 305 the other size? http://www.smcbike.com/products/carb...rim-wheel.html

    That velocity posted above looks like a great option.

    Correct:
    305 is decimal sizing and what most kids bikes (including the Yoji) use
    349 is fractional sizing, slightly larger and most commonly found on bmx race bikes

    The velocity rim is ~$100, though, so not particularly cost effective vs getting a different hub for the 16h rim from tr Yoji or the 20h rims I have sitting around. The SMC rims I think were even more.

    Right now I'm thinking it might make sense to get started me cheap spokes, try building the wheel myself on the narrow rim and start planning for a 20" front wheel in a few months as he grows. I'll admit that I'm somewhat tempted to try it now.

    Oh, test other small setback: the narrow rims are drilled for presta and no one in town seems to carry 16" presta tubes. I would consider just widening the hole if it wasn't such a narrow width already.
