Isaac Proton XC Hardtail Mountain Bike.
I am one of the latest additions of the Isaac program. I am different from all other models within the Isaac program, but I can furfill the expectations that you would have from an Isaac bike. I am built for pure speed and get on well with irregular surfaces. With my elegant look and good quality I am a perfect partner for every mountainbiker.

I am completely assembled with Shimano and available in sizes S, M, L and XL.
Besides the total bike I am also available as frame. Do we hit the road for a top performance?

I am Isaac Proton XC and I am ready for the battle!
