OneUp Expands Chain Guide Range

Building on the success of the ISCG-05 Chain Guide, OneUp Components have added two new guides to their line: The OneUp Bash Guide ($79 USD) and the ultra-light OneUp Low Direct Mount Guide ($32 USD). At OneUp Components, we believe chain guides don't need to be expensive, heavy or difficult to set-up.

OneUp Expands Chain Guide Range

​OneUp Components expands their line of simple, yet well-thought-out chainguides with the addition of two new guides, the Bash Guide and the Low Direct Mount Chain Guide.

Vital MTB - 8 April 2016


OneUp elevates chain retention with new lightweight chain guides, with or without bash guards

Chain retention on most 1x chainrings is usually enough to keep the chain from dropping. Usually. For those who can’t afford a dropped chain or just want more peace of mind, chain guides are making a comeback. But they’re also undergoing constant improvements to make them lighter, more compact, and drag free. The new guides from OneUp will help keep your chain in place and may just save your chainring…

OneUp Shark 50T Sprocket Kit - Review

The Shark Cog and Shark Cage allow a rider to greatly increase their gearing spread, and not only their low range but also their high range if they decide to go with a suitably larger chainring. This could be a real benefit to a rider with greatly varied terrain.

OneUp Goes 10-50T - Shark is Here and its Big

I headed up to Squamish earlier this week to jump the Shark myself and came away impressed – and with a 50T cogset on my Nomad, as well as a chainring jump from 30 to 34 teeth. Does everyone need 50 in the back? Hell no. But if your terrain goes up steeply in places and you’d like to be able to reach decent speeds on roads or wide open spaces of trail, then this represents a huge opportunity. - 21 March 2016


First Look / First Ride: OneUp Components Shark 10-50T System

Looking for the ultimate in range with your 1x setup? OneUp Components announces the release of their Shark 10-50T modular upgrades for the current Shimano 11-speed cassettes.

Vital MTB - 21 March 2016


First Impressions: OneUp Shark jumps Shimano 11 speed cassettes to 10-50

So who is the ideal customer for the Shark? As an upgrade, the system makes a lot of sense for anyone wanting more range out of their current Shimano 11 speed 1x drivetrain (or anyone who may buy a complete bike with Shimano 1x in the near future). The Shark kit also seems like a real option for anyone trying to gain the widest range 1x drivetrain on a budget.
