Agile Gravel Geometry
- DN6 Chromoly Custom Drawn Steel
- Full Bottle / Mudguard / Pannier Mounts
- Tyre Clearance 700c x 43mm
The core geometry of a fast and agile gravel fun machine. 71 degree head angle offers a trail figure that tackles singletrack with ease, yet sprints and climbs as capably as a racer. Road inspired reach figure keeps things fast, whilst the large front triangle adds frame bag capability and timeless looks. The 70mm BB drop keeps the rider planted like a road bike. Steeper seat tube creates efficient seated climbing position. Shortened 425mm chainstays keeps the back end agile. 700c x 43mm / 650B x 2.1-inch tyre clearance gives limitless exploration capabilities.
Triple Butted DN6 custom drawn steel results in a frame that is strong, responsive, and comfortable whilst shaving off excess weight. Tube wall thickness is strictly controlled to offer strength at welds and lightness. Arched seat stay bridge reduces harsh feedback and further increasing tyre clearance. Hourglass shape seatstays and chainstays reduce road buzz and add spring. A 28.6mm diameter toptube and 34.9mm diameter downtube offer sprightliness and strength alongside a 27.2mm seat post for comfort. 29.8mm seat clamp is required. A custom profile head tube allows for a large weld platform and bigger bearings. Resulting in a stronger, less flexible, and better handling front end without excess stiffness.
3 sets of bottle cage bosses, full mudguard, pannier bosses, and top tube bag mounts. Ready for multiday gravel adventures. Pannier mounts and full mudguard capability make it perfectly suited to commuters and off-road tourers. Down tube has triple water bosses for frame bag clearance.
The BSA 68mm threaded bottom bracket is ultra-durable, creak free and easily serviceable.
Smooth and confidence inspiring. The frame geometry has been designed in tandem to ensure fast and confident tracking and avoid toe overlap, even with mudguards. Frame Weight: Large 2.4kg
