TECH

The WR38 was built with one goal in mind: the absolute best long distance gravel rim. The massive 25mm inner width provides a stable profile for even the widest gravel tires. At 38mm deep, you get an aerodynamic benefit without making it hard to control in crosswinds. With a 32 or 28 spoke hole count, the WR38 makes an excellent bike packing or touring rim.

Our Falcon Pro line of rims feature all of our latest manufacturing technologies. The scratch-resistant BlackTek (Paintless) finish will keep your rims looking sharp for miles and miles.

I need wheelset with 240 dt swiss hub, depth 50mm, disc break wheel.


LightBicycle 2020/12/22

Hi Pai, Are you looking for DT SWISS 240s or new 240 EXP hubs? For the 50mm deep rim, will the WR50 (25mm internal, 32mm outer width) road disc ok for you? What is your tire width? Thanks, Lightbicycle

How Can I specify in an online order a customized laced for Cannondale AI 6mm offset? is there any extra cost for this? Do I have to do it in the last step before payment?


LightBicycle 2020/10/01

Hi Pablo, Thanks for your inquiry! Yes, it is okay to build rear wheel with cannondale ai 6mm offset. You can list your wheelset specs here, we can work on invoice accordingly for you.Or you can place the order through our website, but leave a message on the order " rear wheel ai 6mm offset". Then we can see it and will double check with you to make sure everything is correct on your wheelset disc. Thanks, Lightbicycle

Can you build with SILVER Sapim CX Ray spokes and SILVER nipples? Best, C in Toronto


LightBicycle 2020/04/28

Hi Corwyn, 1. Yes, we do have Sapim CX-Ray spokes and Sapim Race spokes in silver. Could you be more specific about the configurations you want to have so we can calculate the spoke lengths and check with the spoke availability? Some lengths are hard to find. 2. Yes, we do have Sapim Polyax nipples in silver. 3. Since you are in Toronto, we can ship the wheelset from our Canada warehouse. Do you like spokes only or complete gravel wheelset? Thanks, Lightbicycle
