i am riding 2x9 ( suffer when unfit though) 40-27 Rotor ring on a 11-34 cassette and loving it.

After much mulling it about, I built my 29'er with old school gears and haven't been sorry yet. Good old 44/32/22 with 11x36. Can ride up the side of a house if it comes down to it, and with a 44x11 on a 29'er, you got some serious speed when its needed.

Hehe. I can climb pretty much anything in the big blade so wondering what's the point of small blade

 

You and Philippe Gilbert maybe ... come play in Sabie some time and then we will talk. The Mamba awaits you.

I'm about to go from a 1x10 on my AM bike (34 / 11-36) to a 2x10 (34/24) as climbing some trails with a 14kg bike is occasionally rather tough on these old legs.

 

What cranks are you guys riding that you can get such kif blade sizes?

I can't find anything for X9 10 speed cranks , I want 24t small blade...

I have a Middleburn crank on at the moment with a custom made 34t blade.

 

I'm going to put on Blackspire blades on a XTR 960 (34/24)

Eeish that's my dream blade setup but it'll probably cost about R2k for the 2 blades alone?

Thanks - lots of useful feedback there

 

General consensus seems the 3 rings up front come in handy for Joe Average in the big mountains, which is what my intuition was telling me. Although it should be said I am Joe Below Average, consistently finish in the last 1/3 of the field. Well at least I am consistent. And finish.

 

In terms of FD: seems they are specific, either 2x10 or 3x10, which adds to the commitment.

Running with a XTR 40/28 crank on my 26er with 11/36 cassette. Don't see the point of a granny if I can run faster with the bike on my shoulder

[Icycling]

I am not a MTB rider - but for the life of me I cannot understand why people who change to a 29er also now want to change to a 2 x10 when on a 26" bike they were running a 3 x 10. The size of the wheel changes the gearing completely ( a bigger wheel makes a heavier gear).

 

I would suspect that the only cyclist racing nearer the front of the pack are actually able to successfully ride these gears! It was completely by co-incidence that 2 x10 came out at the same time as 29ers from what other suppliers have told me!

 

As per the comment above (Moridin) I think the 2 x 10 was actually designed for 26" bike

[Ranga]

I had my first ride with 2x10 yesterday. I thought it was fantastic!

More usable gears per chainring, so much less worrying about crosschaining etc

 

I have 38-24 rings with 11-36 cassette on a 29'er

It's almost the same as 22x32x44 with 11-34 on my 26" bike (well, on the climbs anyway...)

 

I went from a 26" to a 29er with the same ratios as yours and in my opinion there ie hardly any difference between the two on the climbs.

I much prefer them 2x10. For me the 2x10 ratios are perfect.

I maybe would have prefered a 39t instead of the 38t on the big ring.

What crank comes with a 24 small blade?

that is the ultimate small blade for 2x10 , but the ratio of your small to your big blade is a bit big

Most cranks come with something like a 26 or 29 small blade which is not kif

 

I got a standard 38-26 XT crankset and replaced the 26 with a Shimano XT M770 10sp 24t ring.

It is quite a jump between rings, but it seemed to work fine.

 

Sram has some sort of conversion kit for their 2x10 cranks where you buy a new spider and smaller rings with bashring. Some Specialized bikes came out with Sram 38-24 and even 22 rings, but there were no after market replacements, so when they wore out, there were problems.

For 2013, Shimano are supplying 38-24 cranks on some bikes and are becoming available to the public bit by bit.

Stoked , thanks for that , ja early 2x10 setups didn't offer many smaller blade options

It's nice they are now wising up to what the market wants.

 

I noticed I prefer the ratios across the cassette with something around 38-24 blades , which is pretty much what I had when riding 2x9

And with a 24 blade to a 36t on the cassette you pretty much get your ultra granny gear back

Anyone gone to 1x10? I rode entire k2c in bug blade.

 

Depends what you big blade is. A 36 is not as impressive as a 42.

You've got it in one. Do we ride for fun and to enjoy trail riding spinning comfortable ratios when we want to? Or is it all about telling everyone else how hard we are?

 

The facts are with a 44/32/22 and 11-36 you get the same bottom end as on any 26er which is about 6 kph at 90 cadence but the top end is like a road bike at about 48 kph at 90 cadence. Perfect for 100% of the riding I do.

24x36 on a 29er gives you 19.05" per pedal turn. The old 22 on a 3x9 on a 26er gives you 16.73" per pedal stroke, about 14% easier than the replacement on a 29er. So not quite the ultra granny, or as Shimano called it for a while "Mega-Drive".
