As an avid biker, you know that when it comes to replacement parts you cannot do much better than a Shimano XTR cassette. The Shimano company began in the early part of the 1920s and the founder got his start building free wheel components. The free wheel screws onto the external threads of a hub. Cassettes updated the design by integrating all the parts into one. You can find a new 10 speed Shimano XTR cassette for your bike quickly and easily by visiting eBay. The many reliable sellers offer various bike components like cassettes, free wheels, tires, and cogs for any type of bike, whether it be a racer or just a casual cycle. If your racing bike is in tip-top shape but your mountain bike needs a bit of TLC, grab a Shimano XTR M900 cassette. Perfect for an 8-speed bike, the M900 will give you the smooth gear shifting you need on those back trails. And with all the convenient shipping options, you can get your Shimano XTR cassette sent to your door or to your favorite bike shop for the switch out.
