High quality bicycles with conventional wheels use spokes ofstainless steel, while cheaper bicycles may usegalvanized(also called "rustless") orchrome platedspokes. While a good quality spoke is capable of supporting about 225kgf(c. 500pounds-forceor 2,200newtons) of tension, they are used at a fraction of this load to avoid suffering fatigue failures. Since bicycle and wheelchair wheel spokes are only in tension, flexible and strong materials such as synthetic fibers, are also occasionally used.[3]Metal spokes can also be…

buy electric bike bar ends

2018-03-16 خبر بدون نظر

In cycling, bar ends are extensions typically fitted to the ends of straight handlebars.They extend away from the handlebars and allow the rider to vary the type of grip and posture that they use during a ride. They are especially effective when climbing out of the saddle, because they increase leverage. Bar ends can also improve comfort for the rider due to the neutral position of the hands (palms inward) which places marginally less stress upon the musculature,and by providing more than one place to rest hands on a long journey.
