The Thomson X2 Road stem allows you to realise the benefits of stiffer forks and stiffer 31.8mm bars. X2 offers precise steering, tracking and more control while riding and is all wrapped up in a beautiful design. It features a lighter, 2-bolt handlebar clamp and the interlocking handlebar clamp makes it as torsionally strong as other 4-bolt designs while being lighter and narrower. The X2 also has a low 36mm stack height and is available in 2 rise options; 10 and 17 degree. Both the 10 and 17-degree stem can be run with a positive or negative rise and the reversible graphics look great in either direction. 10 degree stems work well for average riders/amateur racers while those who want a very aggressive aero position or who want a very upright position can use the 17-degree stem to meet their fit needs.
