Knocking / vibration

Ok folks, quick one.



I was riding around Castleford last night (yea rough side oftown ) and i noticed a repeated knocking through the pegs. This seemed to ebat low speeds and most evident at 4k rpm regardless of speed (say 20mph at 4kand 30mph at 4k is more noticeable than 20mph at 6k) nowthen i took a look atmy front tyre and its got a large piece of swarf in it. (looked like a nail onfirst inspection.) So got home and pulled this out (tyre ok) but im stillgetting the vibration (all be it reduced) Im thinking

a) Damaged tyre, replace

b) Stiff chain link possibly , replace

c) Rider that worried too much, replace



Whats the orgs opinion?

Tyre structure maybe damaged if cords cut. Get someone to pull bike over on stand and spin wheel to see if there are any bulges. Same for chain on rear, just turn gently feeling for tight spots and watch chain links as they leave sprocket to see if they stick. Would not have thought it was your chain unless you park it up wet and unlubed and just leave it to rust. You sure there is nowt in back tyre? lol

yea back tyre looks clean

no bulges in either :/

chain is well lubed. has one stiff link.

btw stiff link is still movable just feels a tad notchy compared to the silky smooth others.
