Good tyre at a good price

- Hem 4 July 2025

As the tyre is really flat on delivery, unlike other tyres that already have some shape, the first fitting requires a lot of patience to get it to sit around the rim for further fitting. Watch instruction video and keep trying. Once everything is on the rim, you won't bother with it at all later on, in case of a puncture or id. Been riding with them for years, function well and look good.

Pros & Cons

Good dry and wet traction

Don't start this band

- Sebastian 8 January 2025

It's really not as top tyre as you might expect for the price and what you read. Instaltion is a huge hell that makes you lose all the fun in cycling. It cost me several tubes and tyre levers. Skinwall was quickly broken, unfortunately this was solved well by Mantel and I got a new tyre, this meant I had to go through installation hell again.

Pros & Cons

No
Fun in cycling disappears with installation of the tyre
Skinwall always dirty after one mud run
Skinwall broken after only a few races

It looks nice because of the brown sidewall.
