COMPLETE HIGH-END 29ER WHEELBUILDING KIT
This kit combines a lightweight modern 29er carbon rim with one of DT Swiss' premium MTB hubsets.
The H25-W35 rim is only 25 mm deep and weighs approximately 380 grams. Its 35 mm external and 29 mm internal width make it ideal for modern XC, marathon and lightweight trail tyres.
An asymmetric 3.85 mm offset helps improve the balance in spoke bracing angles and spoke tension between both sides of the wheel.
Combined with DT Swiss 240 Boost Straight Pull hubs, Alpina Ultralite Aero spokes and lightweight aluminium ABT nipples, the complete wheelset is expected to weigh approximately 1,350 grams.
