Wilier Aerokit Rave SLR ID2 — Seat Tube Unit

Wilier built the Aerokit around a simple idea: fold hydration into the Rave SLR ID2's aero design instead of bolting it on as an afterthought. This is the rear unit, the one that mounts on the seat tube, and it includes a mounting base, bottle cage, and a 550 ml smoke-grey bottle.

One detail worth noting for anyone dialing in their drivetrain: the base is already set up to take a chain guide, no extra brackets or workarounds needed for double-chainring setups.

Worth knowing before you buy: this unit only covers the seat tube. For the full aero effect Wilier designed into the Rave SLR ID2, it needs to be paired with the matching down tube unit, sold separately. We always recommend buying both together — anyone going for the complete integrated look should also look at AEROKIT BOTTLE SEATTUBE RAVE ID2 - GREY as a companion purchase.

If you just need to replace or add the rear 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.

In the box:

• Seat tube base, chain guide-ready
• Bottle cage
• 550 ml smoke-grey bottle
