Shimano Gears

[A Yeung]

Good Day All I have been curious and wanted to know about the differences in models of Shimano
shifter, derailleurs etc. like, Atlus, Decore, LX, XT, XTR and others, Is the highest model get a
better shift than the other or just the weight , costruction material that made the difference. It
seems the highest the model,the more you have to pay. As I am thinking of changing my bike's gears
and it is worth it ? Many thanks for your comments and advice.

I think you will find that different models are/were built for different purposes; racing,
kmart/target/toysRus, touring, mtb, etc.

Being a tourer, I prefer steel with the longest cage (allows widest gear range) on the rear. Fronts
can either pull to highest or lowest amd I again like long cage and widest swing.

YMMV

> It seems the highest the model,the more you have to pay.

As previously mentioned, you could be paying for the image associated with the name. If you do buy
top of the range, please let me know it the high quality parts really do attract the chics {.
OTOH, its probably not worth the effort.

Higher-end parts tend to shift more smoothly and precisely than the low end ones, and they do so
with less weight, and generally better durability. At some points on the line, you get better
features, too (9 cogs on the rear, etc).

Yes, the higher-quality stuff costs more to make, and is probably made in smaller quantities, too.

It would depend a lot on the age of the bike, how much you are prepared to spend (drivetrain
upgrades can be very expensive), and whether you really need the upgrade (could your money be better
spent on other things?). It may well be better to replace the bike outright, there isn't much point
in upgrading a low end bike with high end parts. YMMV, of course.

According to my Shimano 2003 catalogue the XTR front derailleur, crankset and rapid-fire shifters
are heavier than the XT versions.

I didn't know that. But as a general rule, the higher you go, the less weight you get.

Some possible explanations. The new XTR cranks include their new BB design with BB axle as part of
the crank. This adds weight that in XT is probably measured separately as the BB.

XTR shifters are built into the brake levers for STI style braking and shifting with one lever. Thus
the heavier weight may include the brake lever also.

Not sure about the bottom bracket but the XT levers also includes the brake lever and is 2 grams
lighter. XT is 410 grams and XTR is 412 grams.

fairly comprehensive guide on component weights can be found at http://weightweenies.starbike.com

I still reckon if I could lose that 5kg spare tire it'd be cheaper than an xtr grouppo

I agree. Money spent at Jenny Craig would be money far better spent Perhaps the next Shimano upgrade
will be a Shimano Calorie Counter! (Get the Carbon model).

That covers half the range! Altus, Acera, Alivio. The mechanic is a gear snob. Maybe he doesnt like
them because they are cheaper to replace than to repair??
