[RBW] Re: 40-ish mm Tires on Thinner Rims?

The ISO (int'l standards org) has crystal clear recommendations for inner rim width and tire width, but they're not regulations. A couple of years ago I posted them in some form somewhere--and we had an internal talk about them--and all of us here and tons of you there have had the

[RBW] Re: 40-ish mm Tires on Thinner Rims?

Thanks guys! As always, great info. I think I'll just run them on my Open Pros for now. And when I have a bit of spare change, I'll upgrade to a 23mm rim so they can run a bit truer to size. Eric On Thursday, December 1, 2016 at 12:53:48 AM UTC-5, Benz, Sunnyvale, CA wrote: > > No one has

[RBW] Re: 40-ish mm Tires on Thinner Rims?

No one has mentioned this yet, but for some types of brakes, having a big difference between the rim width and tire width will cause problems with wheel removal, simply because the brakes can't open wide enough for the tires to pass through, even with the QR actuated. For example, on my

Re: [RBW] Re: 40-ish mm Tires on Thinner Rims?

It may be the same BQ article where Jan stated that rim width is not critical when riding supple tires. Regards, Richard On Tuesday, November 29, 2016 at 1:27:09 PM UTC-5, lum gim fong wrote: > > One of the recent bicycle quarterly magazine is had a article about rims > and tire wits. --

Yup. Thanks for point that out Steve. Sheldon's site is still the standard reference point. Cheers, Bill in Roswell, GA On Tuesday, November 29, 2016 at 1:23:59 PM UTC-5, Steve Palincsar wrote: > > > > On 11/29/2016 11:37 AM, Scott Henry wrote: > > Please remember the source for your info. >

Paul, Any Cyclocross racer that raced as Scott said "back in Sheldon's day" ran tires marked as 35mm but measured 32mm on Open Pro rims. That was a standard CX racing setup. I still run the same setup on my classic steel CX bike. I did try running Pasela 35s on Open Pros and they were OK as

True, sheldon's site does get updated.Once a month, its almost as if they figured out how to stay on the top half of the page for search results on the web. The bearded one was very bike savvy (albeit very cautious and traditional), the new webmaster... we'll just say the updates are very QBP

Re: [RBW] Re: 40-ish mm Tires on Thinner Rims?

Thanks for the clarification y'all. Seems like, as is the case with most bike things, a few mm doesn't make much difference. Sheldon hasn't steered my wrong yet, but I do try to find a second source usually. Here's another, slightly less conservative chart from

You are better off with rims that "match" the tires; Sheldon Brown had ideas about this and a chart for them. But it's not *necessary.* With wider rims you'll get slightly wider tires and less sidewall flop at lower pressures; you'll also find that your sidewalls don't flex as much for comfort at

Re: [RBW] Re: 40-ish mm Tires on Thinner Rims?

Well, now I'm confused a bit. How much wiggle room do rims have on the max tire size, or does it depend on the rim shape? Have any wide tires ever popped off any narrow rims? I've been wheel shopping. I want to use mostly 38mm tires. The Open Pro is 15mm wide on the inside and is rated for up

Re: [RBW] Re: 40-ish mm Tires on Thinner Rims?

You are good to upsize on those rims, look at a mountainbike someday. Tires can easily triple the rim width. As for tire, I actually recommend these from Pmart http://www.performancebike.com/webapp/wcs/stores/servlet/Product_10052_10551_1168230_-1_400904__400904 Cheap as all get out, not too

I have that exact set up, Mavic Open Pro's with 40mm Clement MSO's. I run them at 60psi and they have been great with out any squirliness at all and no flats with 1500 miles on them. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group. To
