| Fit notes | 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. | A conventional stem and bar can be fitted with a transition spacer (Ridley code SPAAER4ZA012) to round spacers, or with a Deda Superbox stem. Ridley uses a steeper seat angle and lower bottom bracket than before, and a lower head tube with the integrated cockpit for a lower front end. |
