Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer?

Sram S100 1.1 Single ring crankset. Anybody know anything about it?

I am looking to get a new crank for my SS build-up and am considering several cranks. Can anybody can give me a review or tell me if they heard anything about this one?
Sram website has very little information about it.
Thanks.
-G

I'd looked into getting the S300 at one point, and the only information I could find was in regards to the 2-ring version. I went off the assumption that they would be of similar quality and performance. Other than that they seem to be a pretty unknown piece of equipment. Perhaps I'll have to pick one up in the new year and write about it.

The S-300? It's around 100-125, but Google is turning up almost no online shops with it in stock. I hope they didn't stop making it. I really wanted an external BB!

This may help. I recently got some Eighth Inch square taper cranks, which I like, but if you can get the SRAM cranks for $57, jump on that.

Truvativ powerspline = garbage. Their bottom brackets also = garbage + low variety/availability. As far as non square taper track cranks and proprietary interfaces go, this is probably the worst quality of them all.

How is that a touro . Touro is a double while the S100 has provisions for no more than 1 chainring.

well, i suppose it's slightly modified, innit? you'll also noticed that they printed a different name on it. still looks like the same crank. SRAM owns truvativ. i could be wrong, but it doesn't take a whiz kid to connect the dots.

check it.

also, the touro is quite commonly sold as a single - as i said, on a lot of budget SS/FGs. many years of the bianchi pista, KHS flite, and others too, no doubt.

the SRAM S100 uses the same "PowerSpline." coincidence?

Thanks everyone. I couldn't find too much info on it. There is one listed on the SRAM website as a 2010 product so maybe they will post up some more info after the new year. Powerspline huh? I haven't heard good things about it. Too bad. I thought it was a cool looking crank for the money. Guess I'll keep looking for now.

i was thinking about buying those since i wanted the omniums and can't afford them.
http://cgi.ebay.com/SRAM-S300-TRACK-...item5637e05393 i found um on ebay for a good deal. I am tempted to jump the gun on these.

That's interesting. I didn't know the S300 came as a single ring. So I guess the difference between he S100 & S300 is the bottom bracket and it's ability to take a 1/8" chain?

the 300 comes in 2 versions, there is the powerspline, and the gxp. the 100 could take a 1/8" chain too, they're both 3/32".

the 100 is the same as the truvativ touro and the 300 is the same as the truvativ elita.....I use the elita on my winter bike and it's fine....ben's has both models in stock in all the popular arm lengths here: http://www.benscycle.net/index.php?m...h=188_193_1356
the 300 is mos def. worth the small amount of extra cash over the 100 due to it's more durable finish and superior bottom bracket (which will be WAY easier to find a replacement when the time comes than the 100's powerspline)...can't speak to the SRAM chainring's durability since I use a blackspire ring but I'm sure it'll be okay...

EDIT: Sorry, my apologies. I am speaking on behalf of the S300 Track, not the S100. The S300 costs a little more, and is also outfitted for fixed gear/singlespeed/track use. Example. This is actually where I purchased mine from. -- I'm also surprised to see the price having gone up. I purchased mine for 65 dollars with shipping earlier this year.


Eh, sure. Unless you plan on hitting the velodrome, you really won't notice a difference. The bottom bracket is actually readily available (I've looked into it already, that is at least what it looks like). I haven't had any issues with the GXP (Giga-X-Pipe -- this is what the S100 and S300 both incorporate) and I am a big fan of their ease of maintenance. Especially considering that they come by pretty cheap. I'm not sure how you can have a bad quality interface between the crank and spindle, but if it helps, the drive crank is glued to the spindle, and the other half uses the 'powerspline.' Granted, I'm no expert, but I'm not sure that quality is that bad. It's not like it's something you have to mess with on a daily or even monthly basis anyways, it's a sealed bottom bracket, there is no need for it.

Regardless, the only issue with the S100, is it offers 41mm chainline, as opposed to the regular 42mm chainline. And, also, for conversions (like myself) it only offers the use of one side of the crank arm spider. Given it's price, you can't really ask for more.

I have an S300 and really like it. I have never ridden a super high end bottum bracket or crank but it feels really solid and smooth. The quality when looking at it in the packages before I installed it seemed awesome and the tolerences are super tight. I wanted an external bearing bottum bracket and feel like it makes a difference over my friends internal bearing bb's.

Giga-x-pipe and powerspline are pure garbage. The OP would be better off with a converted square taper double.

No.

You're wrong. Completely different cranks.

Thanks, I think I am starting to lean toward the S300. I was looking at the Omnium, but it is a bit pricey and might be a bit overkill for a townie bike; although it is a sexy crank.

Hey Operator, what specifically goes wrong with the GXP BB? Is it an issue with a dodgy bearing or a poor interface or what?

Bearing life is short if you ride year round, the interface can be questionable.

So then I assume an Omnium will have the same issues?

Depends on the bottom bracket used. The higher end GXP is good on the durability scale.
