Speed Tuned Wheels Delta 38 Carbon

From Speedtunedwheels.com:

“What we like most about the Delta 38 Carbon wheel set is how well it performs compared to some of the most popular brands in cycling. The Delta 38 is a high quality, semi aero, tubeless ready wheel set that can be ridden at an attainable price. Our goal was to create a responsive wheel with reliable braking that slices through the air and the Delta 38 is the result. This wheel set is perfect for everyday riders looking for an edge, Crit specialist looking for added responsiveness and riders looking to summit their most challenging climbs.  For the TT and Tri rider, consider pairing the Delta 38 front with a Delta 50 rear rim for the best of both worlds (please use the contact us page for this option). This wheel set is built with the S70 (70 grams) and S241 (240 grams) hubs, and is compatible with Shimano/SRAM 11 speed or Campy freehub bodies. *We recommend Swiss Stop Yellow Carbon Brake Pads for best overall performance and carbon rim longevity.”


More Wheel Facts:

-Delta 38 Carbon tubeless ready clincher rims are 38mm tall, 25mm outer width, and a 17mm tubeless ready inner,  weigh approx. 430-435g/ea.  You can run inner tubes if you’d like.  The rims come taped with tubeless tape, which acts like a rim tape if you plan on using inner tubes.

-These wheels are built with internal stainless steel washers

-The overall rim profile has a bit of a disc shape, its 25mm outer width is mid way up the side of the rim wall.  The rim has an outer width of about 23mm at the brake track.

-Wheel set weights vary slightly due to the carbon rim, and do not include the weight of QR levers, 11 speed spacer, nor the installed rim tape.
