I have Enduro Sport tires on my bike and there is like 1 mm clearance between the front derailer and the tire and sometimes it rubs when I'm in first gear and I dont know what to do. A couple things I came up with are cut the derailer short so its not next to the tire anymore or cut the side tread down which I dont know is such a good idea and it probably would look pretty bad. If I cut the derailer down I would bridge the end of the derailer across the cut ends but the problem is I dont know what to use to attach the bridge part to the cut ends. Also the if I did that the bridge end part of the derailer would be about 3-4mm from the chain but, I could put a thin piece of rubber from the extra mounting hardware for my speedometer on the metal and keep the chain somewhat safe. So, what do you think I could do for this?

Thanks in advance, Greg


Edit: also How the hell do I take my tire off these damn rhino lites???? Cut the frickin thing?????????????????????!!!!!!!!!

Answering your edit - get some tyre levers (most good puncture repair kits will have some).

What? Your front derailleur? It's on the seat tube, which is nowhere near your tires... you mean the rear derailleur?

Edit:here is what the "setup" looks like on my bike, see how the derailleur is next to the wheel? p.s. wow Im surprised someone didnt yell at me for mis spelling derailleur. Another edit oh yea and here is a pic of my bike, in the pic its in 3rd gear but when its in 1st it goes down and in right near the tire.

Did you buy the bike new or used?
If you bought used then some one may have put the wrong derailleur on. If it is new then it may not be on stright.

Also, did you put larger tires on? That could be the problem as well.

When you are in the big ring up front there should be 1 or 2 mm between the derailleur and the top of the teeth and the cage should be inline with the ring. Check that.

One other thing, the limit screw may not be set properly allowing the derailleur to move inwards too far.

p.s. Most people do not spell derailleur correctly so it usually does not get noticed

I did get the bike new, and I did get 2.2 tires and the stock ones are 1.95 so thats gotta be the reason and I know its not anything else cuase when they installed the rear wheel they noticed it rubbed and the only thing he did was adjust the wire. And also what do you think of my idea? I think it seems ok as long as it would hold. or maybe I can get a shorter derailleur but I have no idea what would work.

As long as the derailleur moves far enough to push the chain onto the small ring then you should just need to adjust the limit screw to keep it from hitting. Should be no need to add anything under the clamp.

If the derailleur is to far from the chain you will end up with poor shifting.

As for cutting the tread on the tires, why not install the original size? Cutting the tread will just defeet the purpose of getting wider tires

Shift into the smallest chainring on the front and the largest sprocket in the back. Then check how much clearance you have between the inner edge of the derailleur cage and the chain...it should be around a mm or so. If it's more than that, then adjust the lower limit screw and it will pull the derailleur away from the tire.

Also, is your tire/wheel centered between the chainstays? The wheel could be in slightly crooked or the wheel may not be dished/trued properly (i.e., pulled slightly to the right side).

You may have to go back to a smaller tire to gain the clearance.

I just checked and I have at least 3mm clearance so I can adjust it but, which screw is the lower limit screw? And what does it do just limit how far the derailleur can go in that direction?

Thanks, Greg

Edit:I found a Front derailleur adjustment guide and I adjusted the lower limit screw so that I have about 1.5mm clearance instead of like 4mm and it should be good now, and I wonder why the guy at the bike shop didnt adjust it all he did was adjust the cable.
