Description
Anyone who follows La Plaga’s Instagram knows he is all about grass-roots and encouraging riders to get into bikelife. With that in mind, he insisted we made an entry level bike, branded with his name to help encourage up and coming riders to get into the scene.
Bomma La Plaga st is a 27.5 hi-tensile steel framed bike with single speed drive train, optimised for wheelies. The frames geometry is based on the well proven alloy 27.5 Bomma series. The frame features our awesome peg mounts which allow you to bolt your pegs directly to the drop-outs, saving frustrating bent axles, but also allowing you to remove the rear wheel without a socket set!
We have introduced 2 amazing new colourways for these bikes, which also feature a bespoke signature La Plaga aftermarket spec wheelie seat and pad set.
Pushing boundaries to make sure this bike is super-easy to control on the back wheel, we included a Shimano MT200 hydraulic rear brake and our Snakeskin Stickies tyres (which are designed for swerving).
To sum it up, an entry level bike with some incredible aftermarket level parts which will get you rolling and popping wheelies like La Plaga without having to spend a fortune on upgrades.
