Surly Ogre Frame Set 2027

Thanks to its compatibility with 27.5, 28 and 29-inch wheels, it offers maximum flexibility for city riding, trail riding and touring.

Pairs perfectly with in-hub gear systems (Rohloff or Shimano) and SON or Shimano in-hub dynamos

Sizes: S, M, L, XL

 Update 2027:
Malot’s Earwax will be released in 2027 as a modernised version of Ockerton – a warm, yellow-brown colour profile with a slightly matt, organic finish. The shade now appears clearer, more harmonious and contemporary, whilst remaining true to its characteristic ‘earthy mustard yellow’.
