Anyone done Crr measurements on Fusion X-Guard or RBCC (what's RBCC?).
Ah, this is RBCC "rice bran ceramic compound" dafuq?!
http://www.velodistribution.co.uk/product/irc-formula-pro-rbcc-tubeless-road-tyres-28mm/
25mm tyre 275g (20g heavier than Pro One, 50g heavier than GP4000Sii)
28mm tyre 320g (heeeeeaaaavy!)
RRP £50 (spendy)
No point using long lasting tyres if they're slow though. I could just ride Duranos or Marathons for 20,000k. I assume Pro Ones are faster than RBCC tyres? The rolling resistance site has only tested an XC IRC tyre.
I'm 88.8kg. Bike is ~18kg. I had no issues with tubes last year.
