  • OneUp Components Underbash, ISCG05

    Lower chainring protection without the upper chain retention. If your bike already has built-in chain retention or you simply do not need it and want to protect your chainring, this is your winner!

    As the trend for lower and slacker bikes continues, chainring protection is becoming even more important. The OneUp underbash uses the same simple, one tool installation and adjustment as the best-selling ISCG05 Chain Guide, but adds more strength where you need it.

    The OneUp Bash Guide was developed with input from EWS World Champions, Richie Rude and Jared Graves. Reinforced Nylon bash guards and a back plate cut from 8mm thick 7075-T6 aluminum, ensure that the OneUp Bash Guide can handle the biggest hits, but at a weight of only 68g (32-34t) you may forget it’s even there. The first chain guide designed to be both Oval and Boost compatible

      • Designed for frames with 2 ISCG05 tabs only (Evil, Rocky Mountain, etc). Should not be used on frames with 3 ISCG05 tabs
      • 2.5mm chainline adjustment
      • Includes 3 different sizes of bash plate for compatibility with chainrings from 28-36t - Oval chainring and Boost compatible
      • Mount: 2 ISCG05 mounts (see first bullet point)
      • Reinforced nylon bash guard and a back plate cut from 8mm thick 7075-T6 aluminum
      • Weight: 68g (32-34T)
