Component of the Year Winner
2020's
Component of the Year nominees includes BikeYoke's 213mm-travel Revive 2.0 dropper post, Specialized's wildly light Roval Control SL Team Issue wheels, TRP's e-bike inspired DH-R EVO four-piston stoppers, and this year's winner, Shimano's Deore 12-speed drivetrain that brings impressive performance to a near-entry level pricepoint.
Shimano Deore 12-Speed Drivetrain
Do you know what I'd love to drive around? A white McLaren 720S. And I'd park it inside my Whistler house after picking up a Tim Hortons sandwich with Wagyu beef, naturally. But here in the real world, I drive a sketchy car, live in a tight-fitting basement suite, and eat Tim's sandwiches without any meat in them at all. And if I had to go buy a 12-speed drivetrain tomorrow, it certainly wouldn't be a flashy (and lightweight) XTR system... Unless I had that fancy McLaren, of course.
Instead, Shimano's M6100 Deore drivetrain offers essentially all of XTR's performance for a fraction of the price, and it does it without any of the cheap, plastic-y bits that you might expect to see on a drivetrain that costs around $300 USD. That's right, you can pick up a Deore crankset, derailleur and shifter, and the 10-51 tooth cassette for only $40 USD more than just an XTR derailleur on its own, making it the obvious pick for the Component of the Year.
How does it do it?
The Deore cassette and chain employ the same Hyperglide+ technology used on XTR that's designed to allow for smooth shifting under load; it essentially comes down to the shape of the shift ramps on the cassette, the shape of the chain plates, and how those two interact with each other. The result lets you grab a different gear while you're pushing hard on the pedals without it feeling (and sounding) like the drivetrain is tearing itself apart when you're just trying to get to the top of some steep-ass wall. Other drivetrains ask you to ease up when shifting, just as you would in a car with a manual transmission, but it's almost like Hyperglide+ lets you flat-shift under power like a race car's sequential gearbox. That means you can think less about shifting and more about just getting to the top.
Deore isn't perfect - the cranks and cassette are boat anchors, and the shifter is only single-release - but the budget 12-speed drivetrain simply makes too much sense to not recommend.
"An apparatus (a) that switches gear when a finger presses on it" ?
``The Shimano CS-M5100 is the suitable cassette for the new DEORE 11-speed group.
The distinctively designed HYPERGLIDE ´´
The clutch on my SLX derailleur went to shit after one wet day at Revolution bike park. Rusted to f*ck internally. The problem was not so much the clutch itself but the shaft that the sprags catch on. It’s actually a metal on metal bushing that needs oiling. It’s open to the elements pretty much at the back in the spring recess.
I am going to try GX eagle next I think. I know I will miss the double shift ability of Shimano though.
The pressure on the shifter is light, maybe too light. There isn't that SRAM "chunk" with each shift, which I like. The other issue I have is a vagueness (not sure that is the right word) on what gear you are in when you do rapid upshifts.
I use Rockshox PM600 military grease instead directly on the clutch and the sealing of the housing.
Works really good and PM600 has way better water resistance than Shimanos grease.
Just my 2 cents
I have used now for 3 weeks and over 400km in snow, mud and salt water conditions.
Zero problems. The clutch just works smooth and there is no water, or dirt inside.
I will test that further, but so far I'm quite happy how good it works.
I have not tried it since but I have heard some people say the 12 speed stuff swings both ways.
Gonna throw GX in the garbage as soon as I can actually get my hands on a full XT set
Good work Shimano
Single front suspension component “look at my forks I’ve got for sale”
The same way an mtb fork is called 'forks' by most...
On his Christmas Day test ride out in the street he crashed and scuffed up the derailleur. Happy to say cosmetic damage aside it’s fine, surprised there are not shifting issues. Really does seem like a great product.
Jaguwire housing makes 12 speed feel terrible. It’s made for 1.1 mm cables not 1.2 and causes a terrible feel on 12 speed Shimano shift levers
You can run shimano derailleur with sram shifter in 11s real nice. Idk about 12s but probably
Want 12? Microspline. Oops.
I'm thinking the e13 12spd kit is more impressive.
Are you worried about the cost of the freehub on an inexpensive complete bike?
