Velocite launch tubeless carbon clincher wheels

Bike manufacturer adds deep-section carbon Road Tubeless wheels to range

by David Arthur   March 8, 2013  

Velocite have branched out from producing bikes and have launched the RT50, a carbon fibre 50mm wheelset designed for Road Tubeless clincher tyres. They weigh 1,630g and will cost £1,499.

Road Tubeless was created by French tyre manufacturer Hutchinson a handful of years ago, but despite showing much promise, it’s fair to say the demand hasn’t matched that potential. That’s slowly starting to change though, and at Eurobike last year we spotted Schwalbe’s Ultremo ZX tubeless tyre. In testing they found it to be faster than any tyre they’ve produced before, and also reckoned they had solved the big problem facing tubeless adoption, the ease (or lack) of fitting the tyres to the rims.

Tubeless promises to be more puncture resistant, as there’s no inner tube to be pierced by glass. Mountain bikers have been using tubeless already for many years and the technology is well proven there. Another benefit is an improved ride quality, generally being described as more supple. And you can also run the tyres a little softer as well. The downsides are a current lack of choice and availability, extra maintenance and they take more time to fit the tyres than clinchers (but a lot less than gluing tubs), and the sealant needed to fix any punctures while you ride is just messy.

And there’s now a few more rims on the market. But carbon fibre deep-sections? Nope, you don’t see many of them about. Hutchinson produced the RT1, the first ever deep-section Road Tubeless wheel. But the Hutchinson website doesn’t show them anymore.

So we reckon it’s safe to say these are very rare wheels. The feature a 50mm deep rim with a 23mm cross section, and are finished with a 3K carbon fibre and are clear coated with a matte finish. The decals are removable, should you want to save a bit more weight. They’re also reflective. The rims are constructed using a high glass transition temperature resin, to ensure they can cope with the high temperatures produced by braking forces. They tested them up to 192  deg on their lab machines.

The hubs are their own design, they call them the Velocite Gram. Spokes are 20 front, 24 rear, radial on the front wheel and rear wheel non-driveside, two-cross on the driveside.

Here's a video showing the wheels being tested.

They’re due in the UK this month (which means they’re still on the water) and pre-orders are currently being taken. Interested? You can contact Velocite directly via their UK distributor on

So, if you get a small puncture with this type of wheel, how long does is take to be back cycling (7min for me to swap an innertube), what is the weight+size of the fix stuff, how long does the fix last, are the tyres as puncture resistant as Continental Gator Hardskins? What is the milage like - my previous gatorskins lasted ~2500 miles. Nerd

if you get a small puncture the sealant fills the hole and you don't have to stop at all. that's one of the major advantages.

Apparently each puncture equates to a 10 psi pressure drop, so although you don't have to stop it's advisable to do so - to give'em some gas/air. There a stans YouTube video that shows the effectiveness of the sealant, if going tubeless is not an option putting sealant in your in your inner tubes may be!.

...or buy some Campagnolo Shamal 2 way fits, saving 190g and £500.

Admittedly the Campags are not deep rims but it would be interesting to know if the lower weight off-set the (lack of) deep profile.

Velotastic !

Too many hills, but too little time.
