These are an extremely versatile wheels. I use them for road, gravel, and cyclocross. Strong and light. Very happy with my purchase. Was a huge bonus to get them on sale. Sierra Bicycle Supply is fantastic!
Moved from Crux 4 to Crux 5. Amazing gravel bike. Not a CX bike, but the perfect weapon for gravel races and road training. Two wheel sets and you have the only bike. you need.
Tool was exactly how described and packaging was nice. It did take a few days to ship so unfortunately I didn’t receive it in time for the trip I ordered it for which is the reason for 3 stars but I received it the week after and it’s coming in handy.
