Boardman SLR Carbon
2025 · 700c wheels · 5 sizes
Boardman's current carbon SLR disc race frame (C7 carbon frame, C10 carbon fork, 12 mm thru-axles, hidden mudguard mounts), shared by the SLR 8.9, 9.0, 9.2, 9.4, 9.6 and 9.8 Carbon builds. Boardman publishes the same size table on every build page but does not give head tube length, wheelbase or fork offset. The SLR 8.9 Womens Carbon uses this same frame, labelling the XS, SM and MD frames as SM, MD and LG. Stem, bar and crank sizes are from the SLR 9.0 Carbon build. Boardman does not publish fork offset or trail for this bike. The offset used here (45 to 48 mm) is an estimate: the typical published offset of other bikes of the same type with a similar head angle. Stability and steering results for this bike depend on it, so treat them as approximate.
