2 X 10 - why?

I've been wondering about this fangled 2 X 10 malarky, convinced it's just a gimmick designed to get us buying new stuff, but then I came across this marketing mumbo jumbo, I fell asleep halfway through but I am sure if I had made it to the end I would be on my way to being brainwashed. I say feck them, you'll have to prise the granny ring out of my cold dead hands!

"Through Dynamic Systems Engineering, Dyna-Sys brings together the rider, the bike and the trail. Intuitive gear combinations account for how riders deliver power through the drivetrain; optimization around the 32-tooth Primary Driving Gear lets riders get the most out of modern suspension designs, and even the roughest, rockiest, muddiest trails can’t shake Shimano’s most stable off-road drivetrain to date.

Wha?

Dyna-Sys technology makes shifting seamless and intuitive, enabling riders to deliver consistent, efficient power while maintaining that delicate balance of traction and momentum control. Take a rider accustomed to a traditional 3×9 drivetrain and put them on a 3×10 Dyna-Sys drivetrain in a blind test, and that rider will be faster and more efficient around the same test track. Dyna-Sys delivers a more efficient gear, more of the time.

Yaaaaawn

A wider-range 11-36 10-speed HG cassette means riders can climb further in their Primary Driving Gear—the 32-tooth chainring. When other riders have pulled the ripcord and drop into their granny gear, the Dyna-Sys equipped rider will still be motoring along in a more efficient gear without sacrificing momentum or traction. Furthermore, CloseStep front chainring gear ratios—42-32-24—make shifting smoother and faster. With Dyna-Sys, getting from the 24-tooth ring back into the middle ring—the Primary Driving Gear—is easier and more intuitive. Plus, a 42-tooth big-ring is more appropriate for the needs of today’s trail riders.

Jesus..

Traditionally, triple-ring riders have had to get used to making two to three recovery shifts in the rear every time they drop into their 22-tooth granny gear, complicating the downshift and killing momentum. With Dyna-Sys, the 36-tooth rear cog means the riders can stay in their Primary Driving Gear longer on the same climb, and when they do have to drop into granny, the system only requires one recovery shift, making the entire downshift process smoother and more efficient.

zzzzzzzzzz

Suspension designers are well aware that riders spend the majority of their time in their 32-tooth Primary Driving Gear, and they have optimized their designs to work best in that gear. Dyna-Sys drivetrains squeeze every drop of traction out of today’s active suspension designs."

The Solution
I feel i must admit to all you, the long suffering members of this forum, that due to a tiny ***** and an inability to satisfy a beautiful,sexy , intelligent wife, I have become a drearily boring technophile. For this I heartily apologise for constantly dragging this forum down to a miasma of self pity. However i will continue to do so because I have nothing else and respectfully beg your understanding for this continued drivel
Thank you Don........ I needed that hahhahahahahaha.

On a serious note I've been running 2 x 9 for a n of weeks now and find it very good not that i didnt find 3 x 9 bad you understand. Unlike you I have a big ***** and find it gets in the way when im in granny (not in a granny) and I am a goober so i tried it. I like the 42 big ring and the fact i can run big big because I'm big (not fat) just big. hope this helps you make up your mind to spend your hard earned cash on stuff you dont really need RL and Llandai are great at this. See you later at the races you funny (little man) you.
I take that back, I am in fact , FAT, there I've finally admitted it, I have to because how else am I going to fit in to my wedding Dungarees ..?
Yeah Don, just a load of splutter to get us all thinking 'yeah I need that' and yeah some people will be thinking having seen it in a magazine - I need that, it is better.

But why, as Shimano say, if the middle ring is so efficient, provide a granny - basically they waffle on & on ad naseum to state - you wont need the granny & here's why & then they give you a granny ring anyway.

Sram haven't bothered with one on their new system simply a 2 x 10. I wonder is that why Shimano is much better value?

The thing is - how long will it be before we have no choice - before the shops are only stocking 10 spd chains & the drive trains to go with them? Months, years?
Well seeing as though i am from Corck and can't speak De Valeras English, what the hell do I know !!

Not to worry there are EU laws to protect us good consumers against this kinda thing so it could be years before it all gets pulled from production.
I love you Byrner, not as much as I love Buggsy but almost as much as I love Lynchy
But what they didn't mention was that when it rains a 10 speed cassette will just be a ball of mud and become a 0 speed cassette!
That's what I was thinking, and if your mech hanger gets a gust of wind your indexing will be banjoed. All the tolerances are going to be too fine for our cruddy winters.
Listen to me..
2 x 10 is alright if you are a flaming savage..
I never use my granny ring in my XC bike..I run a 44 -32-22
On my Reign I do be glad of my granny ring !
A mountainbike has 26" wheels 2" tyres and 3 Chainrings..simple.
People who are Cyclists first will like to batter the rest of us with double chainrings..
As the most experienced Spin leader on the planet , I can tell you for nothing, there are way more people out there using their Granny ring than their big ring..way more..
And muck and **** will make any rear block 0 speed..
its just like 29urs..
the people making the money out if the sport are not happy the rest of us are happy with what we have and insist on re inventing the wheel ( pun intended )
Don..you are n exceptionally talented rider on the Downhills..exceptional..be happy with that, you would be a deadly descender on a fully rigid piece of crap..
Cop on to yourself, enjoy your strengths and blame genetics on your weaknesses !
Richie
10 speed gives more gear chioce, so sounds great.
but closer gears and a thinner chain in Irish mud?
Hmmmm
