UPDATE II:
Well, ive just done 30 miles on them & A) I’m still alive & B) they haven’t exploded/melted/turned into a mobius strip etc.
They do roll smoothly, certainly feel like they accelerate quicker & i appear to have a new personal best on one of my long, meandering climbs (about 8 miles), an increase of 0.9mph. OK, there are so many variables that i cant say its the wheels but it made me happy!
I did notice that i felt the bumps more but i have new tyres on & i suspect i have them way to high a pressure (track pump gauge is bolloxed).
What i did notice is the front end felt lighter & i also noticed the side wind more – the bladed spokes make a nice sound when facing into the wind 🙂
Need to experiment with tyre pressure a bit to find the sweet spot but so far I’m happy.
grantyboy – website gives no official weight limit but I’m not sure I’d want to put a 16 stone rider on them! I’m 9 stone so not a problem for me. Check the website or give them a call.
