This is the new and strongest rims I ever tryed EN931/Sapim Cx-Ray/Hope Pro 4 Evo Boost), very stif and fast roling, great acceleration and torsion in cornering, more than 40% stronger than any other strongest Alu rims, no any movement in any milimeter of long riding and races, light and cool looking on the bike, perfect angle of the tire in the cornering with 31mm width! Highly recommend this rims!
We have built my test wheelset with the proven Tune KING Kong Boost hub and light, stiff Sapim "D-Light" spokes.
First you notice:: The rims are really cleanly worked have and a valuable appearance. In additon, they are not exactly thin, which indicates stiffness and a long service life. With 478gr. HR and 506 gr. VR the rims are exactly in the manufacturer's specification. Our test rims are 38 millimeters wide and have an inner diameter of 31mm. This lets the tire work nicely and provides decent grip. Tubeless mounting with the Maxxis DHL DHF combi went smoothly and during the last three weeks I have tested, they held the air very well. The tire always had a perfect fit.
In terms of handling, it is noticeable: The rim is enormously stiff. I have found this to be very pleasant. The low rotating mass is also positively noticeable: The rims have a nice concentricity and respond very directly.
Conclusion: if you're looking for a carbon rim that won't plunge you into financial ruin, you can get a really good deal with the Carbonal. I have completely discarded my reservations and am totally satisfied. In any case, a tip for individualists.
