Good to know: Integrated cockpit · From the frame’s tech sheet · Configurable build
Integrated cockpit (a one-piece bar and stem) on at least one build. Changing the length means replacing the whole cockpit, and not every length exists. Check which length the bike actually ships with before you buy.
From the frame’s tech sheet. BB86 bottom bracket, tyres up to 34 mm and electronic groupsets only: Shimano Di2 and SRAM AXS 1× and 2×, Campagnolo EPS 2× only. The D-shaped aero seatpost (AER10) is 350 mm on sizes XXS to M and 400 mm on L, and needs at least 100 mm in the frame. Headset IS42/28.6 top and IS52/40 bottom.
Configurable build (at least partly: the cockpit or bar width, for example). The stock build below is only one of the options.

Corrected values: bar width
M bar width 400 → 360 mm, XXS bar width 400 → 360 mm, XS bar width 400 → 360 mm, S bar width 400 → 360 mm, L bar width 400 → 360 mm. The manufacturer gives two widths for these bars: at the hoods and at the drops (the bars are flared). I’d entered the width at the drops by mistake. It’s now the width at the hoods, as for every other bike on sedimi.bike. The bar position isn’t affected. Corrections

Ridley doesn’t give a stem length and angle for this cockpit. Instead it says how far the cockpit moves the bars from the frame: SR (stem reach) forward and SS (stem stack) up, both from the point where frame stack and reach are measured. It comes in 5 SR lengths (85–145 mm) and 3 SS heights (55, 75, 100 mm). That keeps the maths simple: SR alone sets how far out the bars are, SS alone how high.
| Size | X, horizontal, by SR | Y, vertical, by SS | ||||||
|---|---|---|---|---|---|---|---|---|
| SR 85 | SR 100 | SR 115 | SR 130 | SR 145 | SS 55 | SS 75 | SS 100 | |

Bar position (bar centre plus bar reach) from the bottom bracket in mm, with the stock 25 mm of spacers. Pick one number on the left and one on the right, for example size M with SR 115 and SS 75. The stock cockpit is in bold (size L comes with SR 115 and SS 75 mm; the manufacturer doesn’t list it for the other sizes).
The bike comes with 25 mm of spacers under the cockpit. Every 10 mm of spacers raises the bars by about 10 mm and brings them 3 mm closer, so with no spacers the bars are 24 mm lower and 7 mm further out. For comparison with a conventional cockpit, size M with SR 115 mm: SS 55 is like a 123 mm stem at −4°, SS 75 is like a 129 mm stem at +4°, SS 100 is like a 140 mm stem at +14° (no cover).
Bars: reach 75 mm and drop 125 mm, 400 mm wide at the drops and 360 mm at the hoods (centre to centre), with 5° of flare. Ridley measures SS to the top of the bar, as in its drawing. I work from the bar centre, about 10 mm lower. Source: Ridley Frame Passport (frame data sheet, PDF), section “Handlebar parts”.
