Hi Spamfish

The 110/100 18 is 110mm wide ( 11cm if your a girl ) and the 100 is a % ratio of the hieght of the tyre compared to the width, and the 18 is to fit an 18 inch wheel. so the 120/80 18 is 120mm wide and 80% of that tall making it a lower profile tyre to the 110/100 so the one you have fitted should be narrower than standard and a bit taller making it feel very slightly higher geared but not enough to notice. hope this helps.

Cheers Grum.

Thanks Guru.

Oh and for anyone else that needs a copy of the bashplate template I just sent it to admin as a GIF/JPEG. Probably best to mark one out in cardboard first and see how good the fit is, if the measurements arent quit right feel free to amend as necessary.

Over to you admin,

Bargos.

Here it is
Cheers Bargos

I'll get working on that this evening.
