Mr. Harry comes loaded with features to enhance your ride:

Ability to fit an MTB suspension fork with up to 100mm of travel or a 29er rigid fork for extra clearance

Why a 29er?

The design of Mr. Harry was heavily influenced by rider feedback, with tyre clearance being a top priority. Running 29er wheels gives you the flexibility to tackle any trail with ease. You can fit both 700c and MTB tyres, offering a wide range of options depending on your adventure. Plus, Mr. Harry allows you to install a full 29er suspension fork if you're looking to add more comfort and control to your ride.
