Shimano Deore XT M771 10 Speed Cassette

The Deore XT M771 10 speed cassette is relatively light weight, shifts smooothly and is durable. It's compatible with Shimano10 speed MTB groupsets.

Light weight Dyna-Sys technology
This Dyna-Sys cassette consists out of 2 aluminium spiders which ensure a low weight and a large support area. The other cogs are placed separately onto the body. These cogs are made from steel, which improves their durability and resistance to wear.

Shimano Hyperglide technology: smooth shifting performance!
The HyperGlyde cogs ensure the best possible shifting performance. Hyperglide is the improved tooth profile design from Shimano. This retained-tooth profile drive system offers smooth shifting, efficient power transfer and good chain stability. The Hyperglide design ensures that you're always shifting smoothly, by constantly looking for the optimum shifting moment. Shifting response times are drastically reduced.

Don't forget the assembly grease!

How often should I wash my bike? Regular washing will keep your bike in good nick. It ensures that the parts on your bike last longer so that you can enjoy cycling happiness for longer. How often you should wash your bike is largely dependent on what sort of weather conditions you ride in. Are you always out there, come rain or shine? Or are you strictly a fair-weather cyclist? It all has an influence on the degree of wear on bike parts, and some of us have to wash our bikes more regularly than others. Refer to the plan below as a general guideline:

October to March:
• Wash every 200 km
• Rinse after every ride
• Dry and lube the chain after every ride
• Let the bike dry at room temperature

April to September:
• Wash every 300 km
• Rinse after a ride in the rain
• Dry and lube the chain after rinsing or washing
