I had problems with High Rollers until I learnt that under no circumstances can you apply any braking at all on the front wheel in corners.
Once I’d realised that, I got on fine and as a result learnt to ride a lot better.
YMMV
Nothing wrong with high rollers, they are a great all rounder.
They need to be lent over into corners hard, otherwise they are pretty vague.
Plus all the other similar replies.
So they punish poor technique with a smack in the face.
Poor design really, isn’t it? 🙂
There was an excellent discussion of the trade offs faced by tyre designers on the original On-One Smorgasbord thread here.
Basically, does a gap between central tread and edge tread lead to increased edge grip?
I’m not convinced it’s a necessary compromise, but then again I’m not a tyre designer. 😀
