Wilier Aerokit Rave SLR ID2 — Down Tube Unit

This is the second half of the integrated hydration system Wilier built for the Rave SLR ID2: the unit that mounts on the frame's down tube, designed to work alongside the rear unit to complete the aero effect the brand engineered into the bike. It includes a mounting base, bottle cage, and a 550 ml smoke-grey bottle.

Unlike the seat tube unit, this base is built purely for the bottle mount, with no extra fittings — its position on the down tube is all about keeping the front of the frame clean aerodynamically.

Worth knowing before you buy: this unit only covers the down tube. For the complete Aerokit as Wilier designed it for the Rave SLR ID2, it needs to be paired with the matching seat tube unit, sold separately — we always recommend buying both together. Anyone going for the full integrated setup should also look at Aerokit Bottle Downtube Rave ID2 - Grey Fumè as a companion purchase.

If you just need to replace or add the front support on its own, this unit works fine standalone too, since it still takes standard round bottles up to 550 ml with no restriction to the included one.
