WHEELS and WHEELSETS

Astuto Competition CX 35mm Carbon Tubular Discbrake

¥179,000

I've been building 'CX' wheelsets for years. What makes them any different? Generally speaking CX wheels will take a bit more 'hits' than your average road wheel so it needs to be tough enough to withstand the drops and smacks. At the same time you want a hub that is super easy to service with good geometry and superb resistance to the elements. Performancewise - keeping the weight down is critical as well as having a good footprint for the tire selections at low pressure.


Our CTX rimset provides the sole of this wheelset. Constructed from carefully matched and blended high-modulus and mid-modulus carbon with special ballistic fabric reinforcement, it's a tough rim and resilient towards heavier hits. It can handle wider spoke tension variations allowing greater tuneability for each rider's preference.


Of course this is a tubular (glue on) design because overall, that provides the best performance for serious cyclocross or pave racing.


Rims: GS ASTUTO CTX35-DB

Hubs: DT350SP

Spokes: Sapim CX-Ray

Profile: 35mm deep 26.6mm wide

Tires: Not included in price - but available!

Astuto Berd Edition ADB 36mm Discbrake Wheelset

¥280,000 - ¥320,000

The latest Astuto / Berd wheelset offers a new level in wheel performance and low weight. Our 36mm CFD designed rimset is perfectly matched to a special DT Swiss / Berd Polylite assembly. This yields the best overall performance possible in a tension spoked wheel with very low overall weight. Rim profile is highly aerodynamic and designed around 25C - 28C competition tubeless tires. Though you may run larger tire easily thanks to the ample inner dimension of the rim.


The Berd / DT System offers unheard of shock dampening and broader tension range than either steel or solid carbon spokes. This allows us to create a wheel that is very stiff and at the same time soak up road vibrations, reduce 'chatter' and stick like glue under any riding conditions.


Each wheelset is meticulously hand assembled by master wheelbuilder and tuned to each customer's individual preferences. Customizing of rim finish is also possible on this wheelset. (extra fee).
