ditto for the RRs.
All year round, light despite being 2.4".
I have though recently built up a tubeless set of Rocket Rons on Crests for a laugh. My Everyday Wheels are Superstar hubs in Salsa rims with tubes, avid rotors and Racing ralph on the front and Ignitor on the back = 2,325g Rear and 2,225g Front (it's a swappable front hub)
The Crest & XTR wheels build up to 970g R and 800g F wheel weights and 1,720g & 1,580g respectively fully loaded with tyres/latex/rotors etc.
That's a weight saving of 605g at the back and 645g at the front (-30%!)
And the weather has just been too dire to test them yet
