RollerBoys 11-Teeth Derailleur Pulley
Take your road cycling up a gear with the RollerBoys 11-Teeth Derailleur Pulley. Designed for road bikes and urban bikes, these jockey wheel pulleys take your ride from steady to unbelievably smooth with frictionless gear changes thanks to the special 11-teeth pattern. This means fewer wasted watts as you pedal, giving you more speed and efficiency
Equipped with sealed CrMo bearings, these bike derailleur pulleys are not only incredibly durable but also stealthily silent, allowing you to shift gears smoothly and quietly. The durability also comes from the EMS Grivory, a nylon composite material offering significant strength compared to regular nylon.
The RollerBoys 11-Teeth Pulleys are incredibly versatile, being suitable for a wide range of Campagnolo, Shimano, and SRAM chains: 9-speed, 10-speed, and 11-speed, Campagnolo 9-speed, 10-speed and 11-speed, and SRAM 2x11-speed.

Le ho prese per sostituire le pulegge originali del cambio shimano sora 9v, ottima compatibilità, controllate il verso prima di installarle. Al momento ho notato che la pedalata è più silenziosa. Vedremo con il tempo e l usura. Di sicuro molto meglio dell'originale di settore su un cambio entry level.

If you have a derailleur with jockey wheels which are mounted with bushings rather than actual bearings these are an essential upgrade for smoother gear changes.You can often tell by spinning the pedals backwards and if the derailleur moves backward and forwards with the chain snagging a little, the bushings are probably binding.Brilliant kit.

シマノ純正より安いですがトラブルなどはありません。7900のプーリーと比較して変速のショックがダイレクトに感じます。しっかりディレイラーの調整がしてあればバシバシ変速できます。チェーン落ちや変速不具合はありません。
