Check before you buy
- Check before you buywarning · Front RotorFront rotor: 203mm exceeds the fork max of 185mm. A post-mount adapter is the part that steps a caliper up to a bigger rotor, sold in the maker’s own discrete size steps (commonly +20mm, e.g. 160 to 180mm or 180 to 200mm) rather than for any gap - and not every step is offered for every caliper model, so check the maker’s own fitment before buying. On 40 of the 177 verified rotors in this catalog. Applies to all 4 variants.
- Check before you buywarning · FrameSteerer mismatch: Fork is Straight 1.125 (single-crown) but Frame headset is Straight 1.125 (dual-crown). Both are the same straight 1-1/8in steerer, so the headset itself is not the question. Check that this frame is rated for a dual-crown fork (head tube length and total headset stack) before you build it. On 17 of the 258 verified frames in this catalog. Applies to 2 of 4 variants.
