by Lorenzo Z. on 29.03.2023 item: black/38-622 (700x38)

They are… OK. If you don’t want to go fast.

Ups:
—they look great (maybe not the most important thing but there’s also this)
—They are relatively light
—They are comfortable
— Actually also robust, taken the point above into consideration.

Meh’s:
— They wear out faster than I expected from some reviews, I rotated them after the first summer and that did help a lot, but I know rotating tyres is controversial on bikes that are ridden fast.

Downs:
— Grip* is lacking on asphalt and compacted gravel. It needs to be really beady these tyres to come into their own.
*Or, rather, they feel floaty and unstable: the grip may be actually there but you never have the confidence to corner as fast as you think you should be able to.
— Perishing after only 2.5 years.
