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

How to Mount The Bashguard:

Taco bashguard can be mounted without the need of crank removal thanks to its open construction. Place Taco behind the crank arm. Try to establish how far the plastic plate is away from the chainring. If it is more than 5-6mm then use provided spacers to bring taco closer to the chainring. Ideally taco should be positioned as close as possible to the chainring itself, but do not use all the spacers to do so. Use no more than 4mm of spacers under each bolt. Once you have established the distance, mount the bolts loosely and position taco in middle of the bolt slots as a starting point or change it to your needs. Tighten bolts with 5-6Nm force.
