I came across a good deal on a mt bike upgrade package to go from 9 to 10 speed including cranks, chain, cassette....anyone try it and will it save me weight? All for under $300.

A link or part number or something might help decipher what you are talking about.

What do you expect to accomplish by going from 9 speeds to 10? One more rear cog will be barely noticeable, the chain life will likely be reduced and the adjustments will be a little more finicky. I cannot see how adding an additional cog can be reasonably expected to reduce any weight, it will likely add a little.

I could personally find better ways to spend $300, but not knowing what you are asking about it's all a guess.

"Cranks, chain, cassette". I didn't see shifter on that list and shifters are generally the most expensive single component.

Saving weight depends on what exactly you have now and the exact weight of the replacement parts. You might save a few ounces but I doubt it'll be enough to notice.

If your bike works well now I would just leave it alone, unless you just have a bunch of money to waste. If it doesn't work well now, I would just concentrate on tuning it up (or getting a different bike if not repairable). Buying that XT stuff won't add $300 of value or enjoyment to your bike. IMHO

That's for a 2x10 upgrade from when you already have 10 speed, not a 9 to 10 speed upgrade.

If you were looking using that as a 9 to 10 speed upgrade, you need to add the RH shifter & rear derailleur, which would give you a complete 2x10 setup, front derailleur are 9/10 speed compatible.

OUCH!
I did not even notice that part??? I was excited. Is there such a thing for 9speeds?

I am in a quandary....bored with the bike not sure what to do Also I have no $ to upgrade to new bigger better....I have been riding my SS 1993 steel rigid bike and having more fun. Debating how to improve the fun factor with out breaking the bank and or making the bike to limited. ie: going SS I need to gears to be a competitive rider here in the great NWNJ area to many hills

XT is a nice crankset, but this isn't a "kit" for converting from 9 to 10 speed, it is a drivetrain rebuild/upgrade package for someone who already has a 10 speed drivetrain. In addition to shifters, you may also want to look at derailleurs. You might be able to use your existing derailleurs but shifting may be sloppy. I had that problem when I upgraded from a 3 x 7 drivetrain to 3 x 9. I swapped the RD but not the 7 sp Altus FD and it worked, just not quite right, until I popped for a new Deore 9 sp FD, now shifts like a dream.

A full conversion like this isn't cheap. Unless you have a great frameset you don't want to part with, or a very specific idea of what you want that isn't available commercially, you might even be better off (money and performance) just to get a new bike. There really isn't anything wrong with a decent 3 x 9 setup and parts in several grades are still readily available.

How about looking for a really good deal on an older, quality road or mtn bike that needs some work (be willing to be a little patient). Buy it and restore, make it your goal to keep the cost down under whatever value it will be worth when you've restored it. It will be a lot of fun, you might learn a lot, and it will essentially be free entertainment (the time spent working on the bike and riding the bike) as you can always get your money back by reselling it. You will have a lot of pride in the bike and want to ride it after its fixed up. Just be realistic about what it will be worth and make sure all the parts are already there and don't looked bent or cracked etc. Make sure its something that you will want to ride and that it fits. Especially try and keep the cost down if it's your first time restoring a bike in case you make a mistake and the bike get damaged beyond repair. This is how I stay interested in my bikes, they essentially cost me nothing, I learn something new with every bike, and I get to try lots of different ones.

10 speed Shimano mtb drivetrains absolutely require a Dyna Sys 10 speed rear derailleur.

Need better info - what do you mean by bored - you just want to change for the sake of changing? Don't know what bold part above means - there is an Edit function that can be used to make your post more understandable. What you need to be competitive is a good training program and lots of miles. You can get lower gears without adding a cog in the rear, but may well need a different derailleur and longer chain. Resist going to an 11 tooth cog on a wider range if possible - just too high a gear to be useful.

I brought my bike (a road bike not a mountain btw) into a shop to get some bars and was wondering about "upgrading" to 10 spd from 9 spd. The sales guy, who was in a position to sell me new crap, told me I already have the upgrade. This shop is a bit unusual in that they build frames and cater to practical folks, but they went out of their way to acquire 9 speed gear when it was phased out in favor of 10 and 11 speed. They still use 9 speed on new builds. It lasts way longer and works better.

"Blue sky" more than ever.

Myosmith

Good to know, thanks.

Even switching from 7 to 9 speed, my RD had to be swapped and the old FD left a lot to be desired until it too was swapped out. I assumed the derailleurs in the OPs conversion would be an issue, but couldn't say absolutely.

What does "Blue sky" mean please?

fietsbob

It's not grey and Raining.. of course .. some people only ride their bikes in fair weather.

I guess the internet has made research impossible. OK, I'm up to the challenge of doing both your critical thinking and your homework. Don't blame me for reducing your IQ.

According to Merriam-Webster, "blue sky":

1 : having little or no value
2 : not grounded in the realities of the present

turky lurkey

Really! So you want to come into this friendly conversation and insult me? Like I'm not capable of critical thinking, or looking something up. You don't know me. "Blue Sky" also refers to a literal weather condition. Why should I do research trying to find out what your silly insult means?

Hahahahahahahahahahahahaha. I'm guessing this is Aaron's. The place that has made themselves famous on the internet for Luddite alarmism and general numbskullery. The place that people laugh at from 3000 miles away.

nope wrong guess, but I think the retrogrouch attitude runs strong in Seattle ;-) I can relate, but hey different strokes for different folks. I do think that the gearing issue has reached a limit though for practical purposes. I think it's pretty well known the skinnier 10 speed and even more so 11 speed stuff wears out a lot faster than 8 and 9 speed stuff. So you have to ask yourself, do a really need that 10th cog? Why? Especially if I was running a mountain bike with a triple crank up front there's really no extra useful gearing you get by going to 10 speed. Also in the gritty off road environment everything is subject to more wear, or in the case of cassettes, clogging, so thicker chains and cogs and more widely spaced cassettes of the 9 speed could actually be described as an advantage. Hence the comment to my 9 speed drivetrain "you already have the upgrade".

AnkleWork

Sorry, I can't help you with your reading comprehension or literal mindedness. I don't know what you are not capable of, only what you've asked and written. See, I'm still helping you with critical thinking . . . you're welcome.
