I’ve had one for a month or so.
I like it, it’s comfy (my first Brooks, long term Spoon user). Seems durable, although the areas around the studs have become a little ‘polished’, I expect it might take a pleasing patina, rather than look tatty over time.
The cloth finish holds dirt, so needs a stiff brush to clean it properly. The rubbery bits grip baggies, which is noticeable when getting over the back wheel, but hasn’t caused any real issue so far TBH. Not a deal breaker, but I imagine it depends on if you’ll find the grippyness a problem – it’s not noticeable when pedalling.
No regrets in buying it, but possibly better for a tourer rather than MTB.
