Really lovely wheelset, from a top name. May not have all the fancy "tech" of Zipps higher end wheels, but come backed with the same warrany. Made in Taiwan, by SRAM adds some measure of comfort about safety and reliability too. Clearly aimed to take back market share from value wheel brands where my money was going until a read up on these. At the end of the day, the replacement policy landed the sale. Sure, they could be another 2mm wider internally, but if you've ever done something stupid like close a car door on your fancy carbon wheels, you'll understand quickly why a liberal replacement policy is handy.

I was a bit skeptical about hookless rims, but as these are for my gravel bike I would be running much lower pressures than the stated maximum. They have been performing brilliantly for the months I have been using them, the hubs are smooth and the freezing sound is a nice happy medium. Not too loud but not silent by any means. A bit of grease in there could make them almost silent if that's your preference. The inner rim width is perfect for high volume tyres, which went on the rims easy with no levers. Tubeless set up was easy. Great looking and performing wheels. Very happy. Only negative would be that the engagement isn't instant and can be feel a little sloppy compared the the 54t Ratchet on my dtswiss hubs, but it's not really a massive issue for me.

I would struggle to recommend these wheels as an overall package. Initial tubeless install was tricky. Panaracer Gravel Kings just would not seat. In the end I needed to add another two layers of rim tape. Once that was done, they seated fine and held pressure well. My big issue is the hubs on these wheels. They're rubbish. Every time I take off the back wheel the hub just pops off! Yesterday it spat out all three pawls and I had to re-assemble the whole thing. Looking online and speaking with Sigma, this is a known issue. With some finesse it can be put back on with a very fine hex key. Worst case though, you have to take off the cassette to re-assemble. It's a shame as they're a really nice wheelset and a good price. I'm thinking it might be better value to have ... MoreI would struggle to recommend these wheels as an overall package.
