The Core SL is BOSSI’s most advanced road wheelset to date. It’s light, responsive and built to last.

Key features are the new carbon lay-up, ceramic bearings and carbon spokes. This resulted in a wheelset with a weight at just 1.275 grams.

What sets the Core SL apart is its spoke system. For this wheelset, Bossi has developed new UD aero carbon spokes to improve lateral stiffness and significantly reduce weight at the same time. This would give an excellent tight and more reactive ride feel than using standard steel spokes. The 2:1 tangentially laced spokes ensure a consistent and evenly divided tension for more stability.

The wheelset features the new Bossi Core SL hubset equipped with TPI ceramic bearings and a 45-tooth ratchet system.

The UD marble finish of the rims is subtle, especially with the laser engraved logos. It gives the wheelset a unique and natural, minimalistic look.
