Introduction On the road, riding wider wheels equate to a faster roll, a more subdued and smoother ride quality, and noticeably improved cornering grip with a more confident feel at the limit. This is why more and more cyclists are opting for wider wheels. As market demand continues to expand, we have developed the ARX series carbon fiber road rims, which are wider than the CRX series, to meet the riding needs of more road bike enthusiasts. We made 8 types of ARX rims in a variety of depths to adapt to different usage environments, 29mm, 34mm, 39mm 44mm 49mm, 54mm, 60mm and 65mm, in style of clincher hookless version and hook version. All of these rims are tubeless-compatible. You may use these rims for road, triathlon, cyclocross, dirt, gravel, and adventure riding. Quality is what we have always guaranteed. Rigidity and deflection control are the most important factors in measuring the quality of a road bike rim. Because of the use of better carbon fiber materials, Toray T700+T800, and the latest manufacturing technologies, we are able to control the rigidity and deflection of premium edition road carbon rims within 0.2mm. This is a very high accuracy. The weight of NXT29ARX is only 370g. Hook and hookless versions are both available. The profile drawing is as below. The tire size for this model of rim is recommended at 28 ~ 60mm. The tire pressure is recommended at 60 ~ 95psi.
