I recently acquired a 2012 cannondale trail sl3 and I love the bike. The one thing I would like to switch up is the crankset. Right now the bike is equipped with a Shimano FC-M430-8 octalink and a Shimano BB-ES25. I found a great deal on a SRAM x.9 crankset but its for a bb30 bottom bracket and I don’t know if it will fit or not. It also says its for a 10 speed cassette but my bike is equipped with a 9 speed which I also don’t know if it will be a problem or not. I have never dealt with cannondale before so if anyone can chime in and help me out that would be awesome! Im just trying to make sure I don’t screw up here thank you!!

Hi there bum!
Someone will come along and correct me if I’m wrong, but I did some research recently as I also found a good deal on a bb30 crankset and my research led me to the conclusion that a bb30 CS will only work on a bike with a bb30 bottom bracket, which mine(and yours) is not.
It’s almost comical that they call these ridiculous numbers of bottom bracket types "standards" when they’re anything but.

They aren’t a match to your existing setup. The 10 speed chain rings are spaced more tightly than the 9 speed set up you currently have so you’d need a new 10 speed front shifter and front derailleur, at the least, to keep shifting working somewhat properly. 10 speed systems and 9 speed systems use slightly different sized chains as well to make things shift smoothly but you could probably get away with using a 10 speed chain on a 9 speed cassette and rear derailleur without having ridiculous results. It still wouldn’t be as smooth as a proper, full 10 speed drivetrain.
Once you got a new front shifter and front derailleur, you’d also need to install BB30 sized external bottom bracket cups (~$30) into your frame to allow you to use the new crankset. This wouldn’t be hard though. Just pull your old crankset off and dump the existing octalink BB. Install the new BB30 cups and put the new crankset on. (Shwim, your setup is probably the same.)
IMO, it’s not worth it to buy the 10 speed crankset unless you really want to change the whole thing over to 10. If you just want to change the crankset that bad, find a 9 speed version. You’d still need to install BB30 cups but would not have to deal with changing out all the other equipment. 9 speed stuff can be found pretty cheap since the onslaught of 10 and now 11 speed systems.

+1 for this. IMO, 9 speed parts are more durable too.

How so?

Physics! The teeth are fatter, chains are burlier, and the shifters/derailleurs have fewer click points (though not the front D I guess).

+2 on how cheap the 9 speed parts are right now! Now if only they made clutch-style 9 spd derailleurs…

Right on bro!!! 😉 😄The push to 10-speed is a bummer but it seems we don’t have a lot of choice in the matter. I think what they’re both doing with 9-spd is total BS. The 9-spd is and always has been a workhorse that has been time proven to be very durable and more than adequate for most applications. For me, this is an effort on their behalf to force me/many into 10-spd. I’m sorry, but It seems Sram and Shimano want to move everyone into 10 & 11-spd chains and cassettes that cost more on the front end and wear out more quickly, which equals to fattening their pockets instead of making products that have been time proven over and over again.

You know what’s really time-proven? Singlespeeds.

Singlespeed is definitely the way to go if keeping maintenance low is your main priority. I think running 1-by is a good compromise; in fact I just swapped out my 2X10 spider for a 1X ring so I can run 1X10 (my other rig is 1X9). Will let you know how the two compare…
But yeah, I’m annoyed that it’s getting more difficult to find 9spd-compatible parts already.

It’s funny, I remember this same argument when 9 speeds came out! Soon they will be pushing a 12 and we will be looking back to the good old 10sp days! 😆 -

Actually, most people have found that 10spd chains last longer than 9spd. Credit is given mostly to improved design and materials. And the chain has to move/bend less for each shift up and down the cassette. BikeRumor actually did a test on that’s worth reading, wasn’t scientifically ideal, but still worth checking out. FYI the plates are the same thickness, just spaced a bit closer together. And derailleur a dont have click points, they’re just pulled around by the cable coming from the shifter, which is indexed.
And +1 to gar29’s comment. This argument has been done every time an extra gear was added!
All that said, I’m riding my 3×9 drivetrain till it dies!!

This is correct. A BB30 crank will not fit the OPs frame, which has a standard English threaded BB. Good news is its the most common BB around, so finding a better crank should be easy, tons of options.
FYI, a standard crank can be fitted to a bike with a BB30 BB shell with the use of adapters, but you can’t go the other way.

That is what I had read when researching. Thanks a bunch for the clarification.

Alright I was just wondering and I appreciate all the info! Looks like im just gonna be waiting for the right parts to come along and upgrade as I go.
