A Guide to Bash Rings

In recent years bashring designs have evolved massively, now being much lighter in weight. They still prevent chain being damaged during accidental knocks, but they are not designed as an aid in mounting obstacles. Some models, such as the Middleburn Pro Trials, are still super strong but carry a slight weight penalty.

There are two main types of bashring available on our website: those with a 12-spline hole in the centre are to fit Middleburn cranks, those with a plain hole in the centre are for screw-on cranks (for use with a screw on sprocket or freewheel). The Tensile bashring is a slight anomaly, it has a 6 spline fitment for use with Tensile UCI cranks but this bashring will still fit all standard 1.37" x 24tpi threaded cranks too.

Some bashrings are cut away completely on one side to remove any excess weight and these should be set up to correspond with your leading foot. When the sprocket/freewheel is tightening down onto your crank this can sometimes cause the bashring to spin a little, leaving it out of alignment with your leading foot. We find that a small amount of grease between the bashring and sprocket/freewheel helps to reduce this effect, and starting the bashring around 30-45 degrees away from it's planned final position will allow the crank arm to 'catch up' once everything has been fully tightened down.
