9Velo Ultralight Road Disc Carbon Spoke EXTREME C52 / C52 Plus Wheelset

Users report weights between 1013g and 1060g including rim tape. Without tape, some believe sub-999g is possible. One user reported 1022g with tape, another 1025g, and another 1060g with steel bearings and tape.

The limit has been inconsistent: initially 110kg, then updated to 100kg system weight. The rim supplier Zen states 90kg system weight. Some users report riding at 100kg system weight without issues, but the ambiguity is a concern.

Yes, the freehub is very loud. Adding grease can reduce noise temporarily, but it remains loud. Some users have tried different greases with limited success. A weaker spring might help, but it's not available.

Yes, you can order them without decals or with custom decals. Some users have debranded them successfully.

The standard bearings are steel; the ceramic upgrade costs about $100. The weight difference is minimal (1-2g), and ceramic bearings may not justify the price. The brand of bearings is not specified, but likely S&S or TPI.

Some users advise against racing or high-torque applications due to the lightweight construction. Others have used them in hard group rides and light gravel without issues. The weight limit and lack of official testing are concerns for racing.

Users report excellent stiffness and climbing performance, with a 'jump forward' effect out of the saddle. They feel lively and responsive, even for heavier riders.

Customer service is generally responsive and helpful. They have sent replacement parts and wheels quickly. However, some users had issues with emails going to spam, causing delays.

Adding grease can reduce noise temporarily, but it remains loud. Some users have tried different greases and ratchet kits with limited success. The noise is partly due to the lightweight rim resonating.

Yes, they are tubeless ready and come with rim tape pre-installed. The tape is thick and adds weight, but can be replaced with lighter tape.
