Difficult to identify the correct size,
Amazon Verified Purchase(What is this?)
This review is from: SKS chainboard hub/chain Universal (Sports)Replacement chain-guards are not easy items to source, even in the days of the Internet. Bought this from Amazon, and it arrived reasonably quickly, given it had an interesting trip around Europe to get to my front door! The main problem is the size guide only relates to the number of teeth on the drive cog, which is not all that helpful. Even the company's website (search for SKS Germany) does not readily reveal the maximum and minimum dimensions the guard adjusts to; a problem to know therefore which of the 3 sizes of guard they make to purchase.
It does have a clever sliding mechanism that allows for the front to back dimension to be altered by a couple of cms. When fitting it to my city bike, I found it to be larger than expected, and the supplied adapters to attach the rear of the guard did not suit my bike. To get the best possible result, I fabricated a bracket myself out of aluminium strip, and this worked well, but is clearly not something everyone would wish to do. It would also help those less familiar with bike maintenance if the description emphasised that in order to fit the guard the pedals and bottom bracket need to be removed, and this requires specialist tools.
Overall, I am pleased with the appearance on my bike: it just fits the available space, looks smart, avoids looking incompatible in terms of style, and works well as a chain-guard. Only time will tell its durability, but at least it isn't all plastic like the original guard that failed after about 10 years.
