interesting read. damn, more stuff to spend money on...

[Tumbleweed]

electronic shifters on an mtb? interesting?

[dirtrider]

Can not see it lasting to long on some riders bikes .

[dirtrider]

There also certainly is no official word on weights or costs, though ?super light? and ?super expensive? are likely descriptors.

I think it'll be a while before we see electronic off-road shifters. SRAM will first have to drop a road electronic groupset in the market and let it run for a good couple of years before they'll take it over to the dark side.

 

But the article sure does make for some interesting reading. Exciting times ahead.

Well here what I think X.X will consist of:

 

Shifters:

10speed Double tap shifters offroad claimtised from the road flat bar kit.

there will be 2x9 specific front shifters in both Double tap and gripshift.

Front derailleur will derived from Road triple and adapted for MTB use to suit 2x9

 

Cranksets:

2x9 options in carbon with replaceable plastic end caps to protect the cranks from damage. 5 arm spider design compatible with 94mm BCD.

Pedal thread insert will be removable to adjust effective crank arm length by 2.5mm incrememt to achieve 167,5mm from 165mm, 172.5 from 170 and 177.5 from 175mm.

Q factor will be low to meet racers demands for matching q-factors on road, mtb and cross bikes.

 

There will be a power meter option developed in collaboraton with CinQ

All cranks will be BB30 compatible.

 

Brakes:

A new lighter weight radial master cyclinder is mated to a magnesium bodied caliper to create the lightest brake system on the planet when mated to reinforced carbon carbon disc brake rotors. these will be expensive but lighter, tougher and provide better braking across a wider temperature range. it will require a proprietry brake pad. Not cheap either.

 

Cassette:

Similar to road.

 

Hubs:

 

Now heres where it gets interesting.

Its here where i believe the most exciting stuff willbe availble. The light weight XC race stuff will be supplemented by a 10s Internal gearbox rear hub that weighs in the 500gr region. This is a lot lighter than Rohloff. Shimano is developing one and SRAM has a stunning 9s version already on the market in their city bike range.

Front hubs will be std QR, 15QR and 20mm bolt thru compatible in ISO 6bolt configuration. Expect ceramic bearings throughout.

 

Wheels/Rims:

 

Carbon rims of course in both clincher and Tubby.

Wider profile to improve tyre stability for sizes over 2.00 (50/50)

 

the finishing kit stuff from truvativ will use nanotube technology all carbon, all as light as Easton whom I believe will manufacture this kit.

 

Forks/Rear Shocks:

 

Not much more in the way of X.X branded stuff herebut the integration between the Shifters, brakes and suspension controls will be neater  via improved Matchmaker (carbon). I also see bars with mounting points moulded in to assist with removing the "is this tight eno.....snap oh crap" scenario.

 

I have not mentioned the rear derailleur because this will cary over from X.0 which will fall away in 2010 model year. X.X will replace X.0 with X.9 inheriting all it's bits for that model year.

 

 

There exciting stuff coming from Shimano as well. Mr Nicolai is feverishly busy designing his 2010 models to accomodate some of this exciting stuff

You should go work for bikeradar! Interesting thoughts.

I have offered to write for Bicycling but they seem to lack imagination..

[Iwan Kemp]

...and budget!

Agree but I think we will see the 20mm disappear and you will only find the 15mm . Had a look at the 15mm last week on an Fox equipped Elsworth . Very neat and easy to remove . Not that the 20mm is more difficult to remove , but u do need to have the allentool

they have enough "know-it-all types" working for them already

You don't need a tool for Rock Shox, Fox, Magura...Manitou and one or two others seem to be a bit behind.

 

But all the big players are tool free.

[dirtrider]

On the 20mm ? Only seen the 15mm that got the QR system .

[MintSauce]

Lefty....You mention Nicolai and you've mentioned being in contact with him before.

 

What's the deal with the 2x drive system they're developing? The system that's similar to the Hammerschmidt?

 

Also, a friend is a regular customer of theirs and when he recently changed his G-Boxx freeride bike for their Ion DH bike, they suggested he not get the G-Boxx II but rather get the standard derailleur type drivetrain and 'wait' before going to G-Boxx again.....found that rather interesting that they'd suggest a customer not get their own system, especially as he was a big fan of his previous G-Boxx?

 

What do you know?

Well how does a 12kg, 120mm travel marathon/trail bike with 2x9, 2x10 or 2x12 internal gearbox sound to you?

 

nuff said.
