| Clip-on aerobars possible | Yes | Yes |
| Seatpost type | Canyon SP0077 carbon aero seatpost, 10 mm setback, clamp with independent tilt and fore/aft adjustment | Proprietary aero carbon seatpost |
| Fit notes | The PACE Bar adjusts 50 mm in width and 20 mm in height (12 positions); Canyon's feature text offers 370, 395 or 420 mm widths, its component table lists 390-440 mm. Classic Drops (130 mm drop) are standard on most builds, Compact and Race Drops are sold separately. MyCanyon lets CF SLX buyers choose crank length, stem length, drops and cassette. The seatpost gives 75 mm of saddle height range in 2XS and 100 mm in XS to 2XL. | The steerer is cut to length when the bike is built and comes with 30 mm of spacers, so the bars can be lowered but not raised later. |
| Aerodynamics | ||
| Manufacturer aero claims | Canyon quotes 204 W at 45 km/h for the CF SLX 8 Di2 in TOUR magazine's test, against 198 W for the Aeroad CFR LTD with the RACE Bar. | At launch: 11.6 W saved at 22 mph (average of 5 and 10 degrees yaw) against Ribble's Endurance SL Disc, about 75 seconds over 40 km. Ribble says the current Ultra-Aero bar has 2.1% less drag than its RI-2 integrated cockpit. |
