Post knobby knife?
Hey just wondering if getting a knobby knife is worthwhile? I know ideally you should just replace tyres more regularly but i dont make that much money. so do I:
A) get a knife and start sharpening my tread.
or
B) Ride it until I can afford to replace it, harden up, and deal with the lack of traction?

I flip the rear tyre so it wears evenly on both sides. Get yourself some tyre levers (If you dont already have them) and get onto youtube, There are so many short step by step vids on how to remove and refit dirt-bike tyres. Its good practice if you have a flat on the side of the trail.

thats good advice. Ive got a heavy duty tube that ive had sitting there waiting to for me to get around to putting it in for months now, i could do them both at once, kill 2 birds with one stone so to speak.

Only problem doing that is you dont have sweat stuff all breaking on the rear it just skids along rather then hooking up


just my thought :headbang

Yep I agree, and you dont get a good square edge hook up, only used the knife once so far but is pretty good!!

Here is something for you to read Saff viewtopic.php?f=341&t=3440&hilit=knobby+knife

I made my own to try. They do work OK. The sharper they are and hotter they are the easier they are to use. It takes me about 20mins to do the rear. I usually wait until the tyre is down to the last 40% and then hack into it. It does help with traction. I only get two or so more rides out of a cut type. They seem to destroy themselves quite quickly.


As Rocket said rotating a rear and you will loose a lot of braking.

Post Re: knobby knife?
so basically the gist of what im getting is knoby knifes are a waste of time, just deal with the decrease in traction as it wears and get new tyres when you can?
