Our MTB frames are designed to take a 90-130 mm travel fork. A useful tool to calculate frame geometry with a wide selection of forks, can be found at Bikegeo. Sirius and Scion geometry is based on an axle to crown length of 480mm.
The design is compact up front which gives great stand-over height. The top-tube is long enough to give you balance and stability going down and keep the front wheel planted going up.
- Compact frame – steeply sloping TT
- Traditional ‘A’ seatstays
- Double bent stays
- Disc specific (no V-brake bosses)
