GMBN's First Ride On The New Shimano XTR | 12 Speed MTB Drivetrain

Shimano invited Neil out to the Italian dolomites to take a look at the new XTR 12 speed groupset, and it wouldn't be complete without taking it out for a spin. The new drivechain has an all new look, but the feel is even better, with larger gear ratios and a newly designed and extra powerful 4 piston brake calliper.

In association with Shimano

Shimano have redesigned their classic freehub body to a 'Micro Spline' version which accepts this new 10-51, 12 speed cassette.
Its a smaller freehub body which has incredible engagement but also runs completely silently as it doesn't make use of a ratchet and pawl system.
Other big news is the addition of a 4 piston brake calliper for that extra power. The brakes also receive cooling fins and the levers get an extra point of contact on the bar to increase lever stiffness.

Holy cow this is a good vid thanks guys for providing good mountain bike content for everyone!

[markonikolic]

Anyone here thinking like: in 15 years when this becomes very old technology i might get it because curently my bike costs much less than this drivetrain.

[MaverickNA]

It's a pleasure to see Neil riding, great skills!

[johngraham]

Fisheye lens, ummm, needs to go! Like throw it away and never use it again...

[danielhuggins]

U guys are legendary I can’t even wheelie a bike but I love what u guys do

[lukenukem]

Like the look of this 12 speed, doesn't look like a mashup of different bits on the cassette.
Love that bike btw. :)

[DanielDunn]

Thanks Neil, always enjoy you reviews. You don’t fluff it too much and I know you can ride.

[stradric]

The engagement on the scylence hub is really impressive. Everything else in this groupset is pretty impressive, but the hub I think is the real major innovation here.

[riggermortisfpv]

It's good to see Shimano's new offering lives up to what I generally expect from Shimano components.

[DueLosGaming]

placing the 360 cam on the riders helmet can give a cool 3rd person view!

[ronaldtartaglia]

Fish eye camera is brutal.making me dizzy.

[ZOB]

All that 360 camera stuff makes the video very disorienting, almost nauseating.

[moragcormack]

I always enjoy your vids, and they always put a smile on my face.

[albertmanzo]

Guys great product tech review and ride !! thank i will be using xtr on my new chameleon frame!

[agaloosjosh]

Actually with the new hubs of XTR, you can hear the good sound of speed⚡🔥

[pierrebroccoli.]

Next bike, when I can afford it, will most likely have 12 speed groupset. Like Shimano but I've not ridden alternatives.

For the haters of the on bike cam work, I thought it was funny. Seems like the camera guy with GMBN got a new toy to play with and was having fun with the background in the process.

[floppydisk]

Man the now gopro camera makes this video so great

[shbnc]

I don't know for you guys, but for me the Canyon Spectral is most beautiful mountain bike ever made.

[alienorgabriel]

The new xtr’s silent hub is a little bit weird for me. Because here the philippines the majority of our mountain biking community prefers a louder hub. Ride safe everyone ✌️
