New Schwalbe monstercross tire

[Fred Blasdel]

"Thunder Burt" is a completely ridiculous name even by their standards, but it should be a great performer:

In Schwalbe sizing, 2.1" means it will probably be around 48mm wide

If your bike fits Hetres with fenders it should fit these with the fenders off

It looks like it uses the same super-supple casing as the Rocket Ron so rolling resistance will be insanely great, but cornering at super low pressures will be vague and durability in unweathered rocks will be poor.
