I was at glentress a couple of weeks a go and I was really impressed with how they have adjusted their trails to force riders into bigger wheels, simply by adding rocks and steps on the climbs.
On the climb to the freeride area I was amazed at how many retro bikers there where stood like lemmings trying to figure out how to ride over them. It was only when I rode straight over them on my 29er they realised it was all about the angle of attack.
There was a couple of trail builders at the top and as I complimented them about the well maintained trails they showed me the 650b specific dirt they have imported for the upcoming enduro. It was so soft to touch, smelt funny though but anything with a small comtact area just can’t bite into it.
The downhill sections from spooky woods haven’t been modified yet so unfortunately I had to walk down most of it in case my wheels left the ground and exploded, or it got too steep and techy for a 29er’er
