Shimano Pro Tharsis XC Stem + Battery Holder is named after the 15km-high volcanoes of Mars, Tharsis is synonymous with long days in the mountains and the spirit of discovery and adventure.
Tharsis components have the strength to tackle the most rugged terrain while retaining low weight because you have to ride up the mountain before you can come back down. We offer the Tharsis line-up in high-strength aluminum alloy which has a distinctive and stylish graphical treatment so that Tharsis parts look as good as they perform.
