Kotavelo R21HD, 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.

Customer Reviews
I replaced my Shimano RS81 with the R21HD. I am very happy I made the change as they are a far superior wheelset. The build quality is excellent, they are a very fast , and also feel very stable cornering. Highly recommended.Mark Burgess (Aug 19 2020, 09:50 am)

Based on a recommendation, I bought a set of R21HDs to replace some ageing Fulcrum 1s for everyday use and after taking them for their first outing this morning I'm genuinely impressed. They feel rock solid yet they have made the overall ride far softer than with the old wheeset. I also found that they increased my confidence on fast descents thanks to the solid bit comfortable feel. Awesome wheels especially for the price. ThanksGavin Matheson (Aug 22 2017, 17:24 pm)
