On-One Summer Season Steel Hardtail Frame 2011
456 Summer Season = Super Slack Steel Steed.
Slacker head angle for pointing Long Travel Forks downhill. ISCG BB mount to keep that chain under control on Burms, Drops, Hucks, Air ETC...FAST. A 65.5 degree head angle places your centre of gravity a bit further back than on a regular 456, the difference being more guts and bigger balls on the knarly stuff.
Super subtle and soft, the 456 Summer Season has become one of our most popular rides. On tough all mountain terrain the custom butted DN6 steel frame rides steady and lets you go faster than just about any other hardtail I have ridden.
3 colour choices. None of them understated. But then again it is Summer and this is On-One...
Yorkshire rose headbadge makes it unsuitable for sale or use in lancashire.
