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 1X13 groupset with integrated power meter and Kleos RD 50 T.E. wheels — a single-chainring setup built for riders who want mechanical simplicity and the lowest possible weight, without giving up power data in training and racing. It's an increasingly common choice for anyone racing courses where a front derailleur just adds complexity without a real payoff.\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. In-store, this is the detail customers comment on most: first-time riders are consistently surprised by how natural the position feels despite the pronounced flare.\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
