Why replace derailleur pulley wheel
Firstly, porous spring position limit could adjust back tension largely, improve the weakness of original weak stretch, and make the up and down chain tension between guide wheel and cogs much more adequately.
Secondly, the contact tooth number or control tooth number between chain and cogs of rear derailleur 17T is more during gear shifting, it just like to pinch the middle and two sides of some sticks, the larger the control lever, the stronger the control power.
Lastly, after redesign the cage’s rotation curve, the distance between upper guide wheel and the cogs is improved.
