27.5” – Grips Bikes

Mafia Bomma TTO Purple

Matt Kyle — Sat, 07 Mar 2026 14:40:50 +0000

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.

BLAD Wheel 27.5″ Purple

Matt Kyle — Sat, 07 Feb 2026 13:48:51 +0000

Mafia’s new Blad wheelsets are the sickest wheels on the market! Whether you need to replace your current wheel set up or just fancy freshening up your ride they’ve got you covered. Fully sealed hubs will keep you rolling faster for longer to help unlock those new combos or just keep you swerving at high speed. Coupled with Mafia’s loud cassettes everyone will hear you coming, if they don’t see you first with all the crazy colourways to choose from. All their rear wheels come with a solid 10mm axle to let you throw some wheelie pegs straight on out of the box.

Snakeskin 2- Black Tyre (26″, 27.5″, 29″)

Matt Kyle — Sat, 13 Sep 2025 13:47:03 +0000

Building on the huge performance of the snakeskin tyre we decided to take the snakeskin 2 to the next level! Refining and tweaking the design to make the Snakeskin 2 the best wheelie specific tyre on the market.

Thicker material throughout the body of the tyre to aide with puncture resistance.

Deeper tread for a longer lasting tyre

Softer compound and a more aggressive knurl for more grip when you need it

Wider profile

Disclaimer – IMPORTANT:

Please note that the snakeskin 2 tyre is 65mm when inflated due to the improved tread depth and construction. This means that clearance is EXTREMELY tight on previous iterations of the Bomma 27.5 frame and rim combination. We therefore do not recommend using these tyres on Bomma 27.5 bikes bought before August 2021.
