BIG BAD JUMBO

As Jimmi, the Founder of OMNIUM, has progressed more and more in to the world of Mountain Bikes, we thought it about time to try and make a small batch for our selves. And this once in a decade frame is not to be messed with. We give to you 5 different sizes of monster 29+ Hardtails (27.5 for S & XS), coated with a special crackle coating that will make your neighbour look twice.

BIG BAD JUMBO

NB! Frames only come with dropout inserts and thru axle – there is no headset, seatpost clamp, or fork.
