The Blackset Race® rim is undeniably, irrefutably, positively light weight, averaging a feathery 395g each. A close inspection of this rim will highlight the attractive aero profile, both angular and curvaceous as the sidewall approaches the rim’s apex. This purposeful use of shape is engineered to create an extra thick triangular section of aluminum to support each nipple, and allows for high levels of consistent spoke tension. In short, these wheels feel exceptionally light, inspire confidence from their stiffness in deep turns and while pedaling out of the saddle, and are simply phenomenal.
These rims are approximately 24mm tall by 19.5mm wide and make use of a maturely pronounced bead hook design facilitating the use of a wide range of tires. The BWW Race rims use welded seams and boast CNC machined sidewalls, for superior braking performance.
Strengths: Exceptional value. Compare them with others' weights and prices and you will see.
Weaknesses: I haven't found one yet.
I've now done 1.25 seasons on these fine wheels. They arrived perfectly true and stress-relived and they have remained that way. They have endured pot holes, dirt roads, railroad tracks and many hard hill sprints. Mine are an earlier set as the progress has gone from Blackset Race to BSR-10 and now to BSR-11. I understand the newer ones have a slightly heavier rim than mine to increase brake track longevity.
These are the best deal going for mailorder wheelsets of Asian sourced parts. They are perfect for those who prefer value over blingy decals and slick magazine ads.
BWW builds their wheels in California; they are not assembled in the Orient. They use the finest European spokes - DT, or in the case of my wheels, the top-rated Sapim CX-Ray aero spokes.
You can find many wheelsets that are similar but they will always be heavier and more expensive. Plus they will be heavier with LESS spokes too. BWW will never sacrifice wheelset strength for the sake of trendy low spoke numbers. You will spend up around $1000 (and above) before you find wheels of comparable weight and strength.
