Here is the Bomma TTO. “The Take over” is the new benchmark 27.5” single speed street-bike for those who demand an all-round performer for combos and traffic work but find the 29” bikes just a little too big. .. With an emphasis on “buy it and ride-it” (no upgrades needed), We took our tried and tested geometry/know-how and packaged it into a lighter stiffer machine. We then wrapped that up in a selection of exciting new colourways to form the basis of your next individual creation. TTO starts life as a lightweight single speed bike, but has been cleverly designed for you to easily switch to gears down-the-line. Simply change-out the rear wheel, rear dropout insert, adding a mech and shifter and you now have a geared bike like BOMMA THRUST. All cable routing is pre-installed and we offer the mech insert as an additional part.
Featuring Shimano Hydro (MT200), hollow tech sealed BB, hydro-formed 6061 alloy frame with CNC machined components and peg mounts as standard, SnakeskinS (Sticky) tyres and 29” alloy double wall rims. To name but a few of the impressive features.
