New XTR for 2003
...more than just a makeover

XTR has remained fundamentally unchanged for years now. And that time has
seen loads of new development in lower groups: nine speed throughout,
splined bottom bracket axles, introduction of disc brakes, etc. But XTR,
formerly the king of the innovation castle, was left on the development
shelf. Until now... The new 2003 XTR groupset gets much more than a
makeover. There are new: cranks, disc brakes, hubs, mechs and shifters.
Cranks
The big story with the completely new, four arm, fully anodised finish
cranks is the bottom bracket and fixing system. Shimano have gone for a
massively oversized bottom bracket axle which will be permanantly fitted to
the right hand crank. The left arm looses the traditional crank bolts in
favour of a pinch bolt over the end of the crank. When you think about it
this makes loads of sense. Splined bottom bracket axles don't need much
tension to keep them in place. Indeed most problems are caused by
over-tightening.

Shifters
Road bikes have long had dual control brake/gear levers for years now but
they've never been introduced mtbs. Until, sounds familiar, now... Imagine
a road STI lever turned through 90deg, okay? Swap the lever for an mtb one.
Braking remains the same. But your shifting is done by moving the lever up
or down. Sounds like a neat idea. It'll leave more room on the bar and allow
you to shift under heavy braking.

Disc brakes
XTR is your racing groupset so Shimano have gone for a lightweight, fully
hydraulic disc system. Fully active two-pot calipers grip onto a
super-light, or so we're told, disc. They've got the weight of the disc down
by making an aluminium spider (the bit in the middle of the brake disc) with
a small steel brake disc. The spider is intergrated with the rotor and
mounted onto the hub with a spline fitting - a move away from the current
'standard'.

Mechs
The rear mechs, long and short cage, have been given a makeover, sort of
Shimano steroids. The only real technical change is the top jockey wheel has
been raised slightly in relation to the pivot point. Shimano claim that this
makes shifting a bit tighter. Hopefully we'll see later this year when we
get our hands on a groupset to tell you how well it all works.
That just leaves the bad news... It probably won't be available in the shops
until the end of 2002. |
Nik, Shimano do actually rule the Road bike world, only a small minority of riders actually use Campag now, due apparently to the fact Campag had a few problems about 5 years ago, what they were I don't know as I only started riding again last year, (Marco may know more), and now most use Shimano, I am a dura ace man myself, and very nice it is to.
I have only seen pic's of the new XTR group and I must say in Gold "YUK". I think they must have changed it for people like me who like nice shiney new things, well sorry but I will stick to my old grey XTR thankyou.
I didn't even like the polished vesion on the Cannondale Good Boy I saw either, it just does not look right anything other than Grey.
