Derby Wheels with Shimano Hubs

Gravel in depth

Derby Carbon BX 25i wheels on Shimano 105 R7070 hubs

Our gravel pick from the Derby and Shimano parts we build with. The Derby Carbon BX 25i is a hookless carbon rim, 25mm inside, 32.5mm deep, about 415 grams in 650b, sized for about 35 to 50mm tires. We lace it to Shimano 105 R7070 hubs in 32 hole.

• Ridges that hold the bead. A retention ridge forms a channel for the tire bead, which Derby says secures tubed and tubeless tires and prevents burping. A deep center channel eases mounting, and Derby says tubeless tires air up with a floor pump.
• Cup and cone on the road hubs. Shimano says this construction lets a mechanic fine-tune the bearing and stays smooth under cornering and sprint loads, and that Dura-Ace uses it on purpose. The 105 hubs add internal O-rings and a grease sleeve for durability.

Derby Carbon DH 40i wheels on Shimano XT M8210 B hubs

Our mountain pick from the Derby and Shimano parts we build with. The Derby Carbon DH 40i is a hookless carbon rim, 39.5mm inside, 31mm deep, about 565 grams in 29 inch, sized for about 2.8 to 3.0 inch plus tires. We lace it to Shimano XT M8210 B hubs in 32 hole.

• The same shape in different layups. The 29 x 35i comes in a trail layup at about 515 grams with a 225 pound rider limit, and a downhill layup at about 630 grams with a 300 pound limit. You choose how much strength to carry for how you ride.
• Quick engagement off the line. The XT and XTR rears engage within 3.5 degrees. Shimano says that helps you get moving quickly, while the seal design and smooth bearings mean less drag when you coast.
