E*thirteen Guidering M chainrings boast a revolutionary dual width tooth design keeping your chain locked on your ring allowing you to pedal through the rough stuff without fear. Precision tooth chamfers help chain engagement even at extreme angles.
A basic shake and bake blend of 8 special herbs and spices (Silicon, Iron, Copper, Manganese, Magnesium, Chromium, Zinc, and Aluminum.) It comes in three different performance blends: EXAr, EXA+ and basic EXA.
Chainrings are fitted to the crank arms and come in single, double or triple configuration. Most geared bikes use a 3/32 inch width, whereas 1/8 inch is the popular choice for track bikes and some single speeds due to its increased strength which is needed when riding a fixed wheel. Chainrings are available in a number of formats, these are known as PCD's (Pitch Circle Diameter) or BCD's (Bolt Circle Diameter), this is the spacing of the bolts that secure the rings to the crank arms. Common sizes are 74mm inner ring Shimano MTB, 110mm middle and outer for Shimano MTB, 110mm for most compact chainsets to allow for the smaller ring combo's, 130mm for Standard Shimano Road and 135mm for Standard Campagnolo road chainsets.
