8/31/2023 0 Comments Rockhopper rigid fork![]() With multiple wheel diameters being offered, the key geometry figures below are for both 27.5in and 29in models in a size Medium for comparison. The bicycle industry seems to be turning back in favour of threaded bottom brackets too, which is no bad thing, because they tend to be easier to service and replace than press fit BBs – and threaded is what you get on the Rockhopper. The frames all feature internal cable routing (where the brake and gear cables run inside the frame’s main tubes), as well as routing for a dropper post, should you want to fit one at a later date. Walls can be thinner away from welds because, generally, strength here isn’t an issue.Ī double-butted tube will present two wall thicknesses, while a triple-butted tube may have three wall-thicknesses along its length (potentially with different thicknesses at either end). This allows the tube to be lighter (because there’s less material) and can also help improve the ‘feel’ of the frame. This means at either end of the tube the wall thickness is thicker, which can help make a strong join between tubes.Īway from the tube ends, the wall thickness is decreased. A tube that is butted has varying wall thickness along its length.
