[求助]求助，关于我的超级不爽的前拨链器！

lain910

<p>我的车车的前拨器最近一直不爽，从中间片变回最小片牙盘时很不顺畅！有时要转将近两圈才能勉强变下来！而且链条和拨链器的摩擦声音很大！感觉像是在锯东西！我用prowheel的牙盘，好像是22－32－44&nbsp;的！我自己看了看，好像是每次从32齿变回22齿的时候，拨链器突起的部分把链条总是压下去，使得链条不能顺利的和32齿的牙盘脱离！也就发出了很大的摩擦的声音（我的拨链器已经装得很低了，装高的话拨链器突起的部分拨不到链条）！</p><p>想问问大家有什么办法解决吗？？难道要换拨链器，还是我的车架结构或者中轴长短（好像就是113mm的长度）有问题！！晕啊！</p><p>变速的时候就像下面几张照片画圈区域一样，拨链器突起的部分把链条脱离牙盘时的升高的运动趋势阻挡了！！链条和32齿的牙盘脱离不了！！</p><p>这几个图都是已经开始向最小片牙盘拨链条，但是拨不下来的状态，突起部分刚好压住了链条！！</p><img src="attachments/dvbbs/2007-1/20071241132525049.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2007-1/20071241132525049.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><img src="attachments/dvbbs/2007-1/20071241138035207.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2007-1/20071241138035207.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br/><img src="attachments/dvbbs/2007-1/200712411381740880.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2007-1/200712411381740880.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br/><br/>

是不是C050前拨也有针对牙盘齿数的区别啊！！？？？

<p>谢谢楼上回帖的各位高人们啊！！我降低后拨就是会摩擦到最大盘！我想可能就是拨链器和牙盘齿数不兼容的问题！！</p><p>实在不行我去换个后拨，快过年了，祝大家新年快乐！</p>

我的前拨已经很低了，再低就碰到最大盘了！！
