Before you buy
- Pick your size: XS (27.5″ wheels) for riders about 145–155 cm · S 155–165 cm · M 165–175 cm · L 175–185 cm (29″ wheels). Full geometry is below.
- Used condition: these are second-hand bikes. Photos on this page show the model; message us for photos of the bike in your size.
- 1x gearing: one 36T chainring and an 11–46T cassette, so there is no front derailleur to adjust.
- Black options on this page are the previous Cascade 4 with 27.5-inch wheels; this description covers the current Charcoal model.
