Introduced last December, the TOGS (Thumb Over Grip System) added a hand position to relieve fatigue on long rides while adding virtually nothing to the scale. For endurance racers (think PMBAR, Wilderness 101, etc.), it could mean the difference between your hands going numb and maintaining your sanity. Heck, they even come in handy if you normally ride paved paths or roads to get to and from the trail.
But, if you had lightweight foam grips like those from ESI, Red Monkey or Lizard Skins, you may be a little hesitant to rip them off just to add a thumb rest. TOGS felt your pain, so they developed the new hinged clamp, letting you quickly install and remove them without touching your grips. Available soon on their website.
