Having ridden on the wheels now for a few weeks I have to say they are well worth the investment.
Due to the reduced weight the "spin up" speed is fantastic, whilst the strength of the rims is astounding. I have pushed them way beyond the 'comfort' zone of previous rims and they just keep performing. If you are searching for a worth while upgrade, these rims are the ones.
Took a chance on a relatively new brand of carbon rims for my custom build Santa Cruz and chose Pure C33 rims on Hope Pro4 hubs. Well I made the right choice, rim quality is superb. Easy tubeless set up. The few rides I have done on these wheels have been amazing really stiff and direct feel to the wheels, superb. The weight drop is noticeable compared to my other alloy rimmed wheels and spin nicely on the climbs and out of corners. Great stuff.
I have thrown everything at the c33 wheels on various trails in nsw from xc to enduro and they have been faultless.They are also dead quite when you hit roots and rocksquality build by pure components
Had these on my Yeti SB6c for a few weeks, then I went to Malaga and rode the rockiest trails I have ever done. Bearing in mind I am 46 and weigh over 200lbs they were not treated kindly!! I was bombing down rocky trails, jumping off of rocks and jumping into and onto rocks. I must admit for the first couple of runs I was a bit nervous of how they would hold up but then I just forgot about them. I had 2 mates who seriously bent their wheels one being completely destroyed but I just kept riding, I didn't even need to true them!!
Amazing workmanship, great customer service and communication, I was a little demanding with the colour matching, highly recommended.
