Cyclocross/Gravel carbon rims are with relatively shallower profile but wider in width. Generally, it is something between Road and MTB rims. 

ProX gravel bike carbon rims are designed with 21mm inner width, which is suitable for gravel tires with size 700*30C-50C. 

Our gravel carbon rims are with 28/33/44mm height optional. 

Apart from bead hook gravel rims (PCX28, PCX33, PCX44), we also provide hookless gravel rims (PZX33, PZX44), whose feature is more similar to MTB rims.

For riders who plan to use gravel bikes more like a MTB hardtail bike, and will use tubeless tire at lower tire pressure (not exceed 50psi), hookless is a good option.

For riders who plan to use gravel bike more like a Road bike, and prefer higher tire pressure (max 90psi), bead hook is recommended.

According to our sales record, PCX33 (33mm height bead hook) gravel carbon rim is most popular with our customers.
