FAT BIKE Author SU-MO with double-butted tubes and steel fork.
Few bikes attract so much attention, but also very few bikes offer so unexpected possibilities and entertainment as Author SU-MO. Enjoy it literally in every season. Best of all bikes it feels on the snow, but you won’t lose any experiences or sport performance even after the snow melts. You will need to learn new habits when adjusting the pressure in his huge, four-inch Maxxis Mammoth tires and as revenge it gives you the ability to break your way through the snow-covered plains. But surprisingly playful geometry of chrome-molybden frame set will support you on more technical trails during summer trips. Functionality and resistance to extreme conditions are also completed by thought-out components like SHIMANO Deore shifters and SAMOX cranks with two chain wheels, which offer the ideal range, in combination with ten gears freewheel operated by SHIMANO Deore derailleur. Enough power and low maintenance requirements are then the advantages of disc brakes TEKTRO Aries.
