Hi all,

I’m looking at these CSC gravel wheels but I can’t decide whether to got the 40x30mm or 35x28mm rim. So basically 23 vs 21mm internal width.

I run 40mm wide tires but want to keep options open for tyre sizes between 28 and 45mm. I mostly ride smooth gravel with occasional rocky single tracks. Not looking for aero gains but some weight savings conpared to old Mavic Allroad alloy wheels.

The trend seems to favor wider rims but I feel like 21mm internal might be sufficient.

Any comments are appreciated! Also in general wrt these CSC wheels.

Here’s a picture of my finished bike. Steerer tube will be cut once I’m certain about the cockpit position. I’ve ridden around 500 km and am very pleased with the frame, no issues while building either. Mechanical Apex groupset and Mavic Allroad wheels came from my previous bike, rest of the parts are from Aliexpress.

Thank you for replies, that’s great news!

I noticed that Cwind now offers the GT20 with a T47 bottom bracket https://www.aliexpress.com/item/1005004927226677.html. I ordered one, expected to arrive in late Jan.
