BETD Cycle components. I phoned the guys there, gave them my measurements and they told me what bike I had!!

I find that it is best to keep the same set of rubber on until it wears out as you learn as you go how much grip they offer on different surfaces.

Isn’t that part of the fun. If everything was dead easy to ride then what is the point?

I would go for the Stumpy for that type of riding. The pitch is too much bike and the XC is probably a bit racy.

Which part can’t you figure out? I guess it id the spoke pattern. If so input 3 cross pattern as that is what most disc wheels are built up as.

Did you invert the bottle of gloop and hold your finger over the spout to allow the sealing particles to gather at the bottom before putting the sealant into the tyre? If not you might not of got enough particles into the tyre. Again watching the video shows this
