In real terms, that's 14.15 W saved at 40 km\/h, and 1'45\" gained over 70 km at the same power output — a margin that matters on race day.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThis build spec pairs the SRAM Red AXS 2X12 groupset with integrated power meter (48-35T crankset) and Kleos RD 52 T.E. wheels, built for riders who want maximum aero performance without giving up power data in training and racing.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe F-Bar ID2 cockpit, developed with the same World Tour athletes, introduces the O.E.F. (Optimized Ergonomic Flare) design: a 3 cm flare between the hoods and drops that, unlike other variable-width bars, keeps hood ergonomics unchanged. All mounting hardware is fully hidden — a first for a Wilier product — while staying within UCI regulations.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe frame also integrates the Aerokit hydration system, co-developed with Elite Cycling: 1100 ml of total capacity split between the down tube and seat tube, cutting aero drag by more than two-thirds versus a traditional cage setup. Riders who still prefer standard round bottles can fit them too — up to 550 ml on the down tube and 750 ml on the seat tube.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eCompared to the \u003cstrong\u003e\u003ca href=\"\/collections\/road-bikes-wilier-verticale-slr\" target=\"_blank\" rel=\"noopener\"\u003eWilier Verticale SLR\u003c\/a\u003e\u003c\/strong\u003e, built for pure climbing, the Filante SLR ID2 is the choice for mixed or flatter courses where aero gains outweigh saving a few grams.
