Great chainguide option

Rating: Featured Member Review
The Good:

easy setup, cost, function

The Bad:

nothing after 2 years

Overall Review:

As is the case with many things, sometimes the best products are the ones you think the least about. This is the case for One Up's chain-guide which has been on a couple of bikes over two years and hasn't drawn attention to itself in any kind of negative way.

Remember those days when you had to remove your crank arm to get the chainguide on?Thankfully One Up has made a point to simplify the installation process with this product. Additionally, they have a shim system which helps you dial in the sweet spot for your chainring that is done at the top of the guide.  Gone are the days of chasing multiple spacers and trying to line them up with the ISCG tab holes.  Once you have fine tuned the guide, you won't need to remove it if replacing a new chainring, just flip up the guide and you have some extra room to wiggle, nice.

Here's what has me really stoked on the product: it's lightweight yet tough enough to do the job. I've had no issues with it and I don’t recall ever dropping a chain. The bonus after all this is that it is reasonably priced. It wasn't too many years ago when I was building up a bike and ended up paying more for the chainguide than I did for the crankset and bottom bracket.  All these features and under $50 seals the deal for me.  

Keep on ridin'

The Good:

Keeps your chain, cost effective, simple

The Bad:

Doesn't come in blue, pink or that new Bronson color of the year

Overall Review:

Long story short, when racing I have (had) a tendency to drop the chain; like a lot, even with a narrow-wide. A worn chain and sprockets more than likely didn't help my cause, but I bought one of these puppies and have been handsomely rewarded for my efforts. Through two normal riding days (which I rarely ever dropped chains anyway), a race practice day and the actual race; I can report no dropped chains. The guide came with everything needed to get up and running. Set up was supereasy; I didn't need any of the spacer for the chain line. My only problem was that my bike only came with 2 ISCG tabs, so I ran the guide with only the lower mounting bolt. Magically, the one bolt has done a great job of not allowing the guide to move at all. In all honesty, along with new grips and a tubeless conversion, this is one the best under $50 purchases you could make.
