I’ve got a MK3, originally I had it setup with 120mm bouncy forks and 27.5″+, because I thought it wouldn’t be capable enough rigid. It’s an absolute riot with the bouncy forks. Far more capable than me.
I’ve now put the rigid forks on and it’s no less capable. It’s fast, agile, comfortable, and made my biking far more enjoyable than anything I’ve had in the last 20 years.
I rode the MK4 at the Steel is Real Demo day at the FOD in October. It’s a different beast to the MK3. It’s a big, slack, lunatic of a bike. Surprisingly light and agile for a 29+ monster truck, but nimble and confident in the tight twisty stuff. Head downwards and it just inspires confidence, point it where you want it and it’ll scream for more than you can throw at it.
The only thing it didn’t excel at was the pump track. It’s just a bit too long for that. But if you are riding pump tracks then a fit for purpose bike is going to win all day long.
Do it. Come join the revolution.
