Kotavelo R21 Wheelset

Kotavelo R21, 21mm Full Alloy wheelset

Finally here after 2 years in design and testing, you asked us for a lighter, faster, more aero wheelset to improve on the Bracciano which was previously Australia's best selling wheelset.  New for 2017, designed for and tested in Australia is the Kotavelo R21.

We've made the rim wider & lighter so that it can accomodate wider tyres and has a better aero transition from rim to tyre, it has been tested to be faster than the old 27mm deep rim.  We kept the Japanese EZO bearings that are famous in our products, we kept standard, easy to find and replace spokes.  We removed some weight from the rim & hub by using better materials and machining.

The final outcome we are proud to say is one of the lightest, fastest wheels we have ever manufactured.

Heavier and more powerful riders have not been forgotten, those who need an an even stiffer, more robust option - we listened and made the Kotavelo R21HD "Heavy Duty" version, using exactly the same rim and hub but with an increased spoke count, heavier gauge spokes and brass nipples.  Heavier or more powerful riders chasing the ultimate mix between performance and reliability should consider the Kotavelo R21HD.

Good wheels, great value

Going from 10 speed to 11 speed meant new wheels were needed, so I'm comparing these to my old Shimano 7900 Dura Ace C24s. Straight out of the box these look good. Putting them on my scales showed they were a bit heavier than I expected, at 674g for the front and 871g for the rear. That compared to the C24s at 627g front and 809g rear. Maybe my scales are a bit off, so compared to the C24s, these are still light. After a few hundred ks on these, I'll say they are very similar to the DAs. They roll just as nicely, spin up the same and just work. The only differences I can tell are that the freehub is noisier (up to you whether that's an issue) and they actually feel stiffer. I certainly feel like they communicate the road surface more than the C24s did. I can't think of any other way they feel different to the C24s. Everyone knows how good Dura Ace wheels are, and these are right up there. Being half the price of the Shimanos makes these great value if you ask me. (Sep 14 2017, 21:50 pm)
