Can anyone explain the differences between the Sugino 75, Sugino Messenger, and Sugino KyotoLoco cranksets? I've become fairly confused by all of it (especially after looking through the Sugino website).

thanks

sugino 75 are niiiiice

sal about en jay es

NJS is only worth it if u actually ride on the 'drome

Sugino Messenger is your basic road crank, but accepting only one chainring. (It's just like the RD crankset, but with a different ring.)

Sugino 75 is a track crank, being much stiffer along all axes than the Messenger, and nearly three times as expensive. (The Grand Mighty is a version of the 75 that is forged many more times over, compared to the base 75, making it even stronger. It, and the 7600 Dura Ace, are the preferred cranks of the Japanese Keirin riders.) For what it's worth, the 75's can bear the NJS stamp of approval.

KyotoLoco is a version of the Messenger crankset that Sugino made to commemorate a big messenger jamboree in Japan. It comes in many attractive colors.

or if you need a big internet penis

Ignorant.
NJS is worth it because its a stamp of quality. By buying NJS you know you are getting a quality part, just like people buy cars from reputable manufacturers and computers with good warranties. Sugino 75's arent any more expensive than a nice set of cranks that arent NJS, they are good cranks at a price they should be.

what exactly are the sugino comp's on '08 langsters? i can't find them on the sugino website or google.

as far as I know langsters come with RD's or the equivalent of. My guess would be they are renamed RD's

far from ignorant
just poor...im not about to spend 30 dollars on chainring bolts when i can get some for 5 at my LBS

haha, agreed, but chainring bolts and cranks are different things. Granted, I ride RD's and find them quite agreeable. I think in most cases buying NJS isnt all that much more expensive than non njs and you are getting very solid parts for the cash (case in point: cranks, hubs, bars etc.)

75s are machined instead of forged?

where would you get that idea? i cant imagine any crank still being made today that isn't forged..

it's possible i don't know what i'm talking about?

just read this. didn't know what i was talking about.

i thought "machined" because the insides of 75s are so smooth and the others have rougher splines on the back of the spider.

Half-right. The NJS stamp means two things: 1. A given particular component, in this case, cranks, is no better or worse than any other given component type of a different brand, thereby levelling the playing field. 2. Given normal and expected operating parameters, the given component is not likely to fail.

It means nothing in regards to performance and thanks to the cost of achieving the stamp of approval and the unexpected recent marketing power of that little mark, the cost is invariably higher.

You can buy Sugino 75's with and without the little stamp. They are the exact same cranks save for the stamp, but one is usually around twenty dollars cheaper.

To wit, do guys who really like NASCAR insist that their cars conform to the NASCAR Aerodynamic Chassis Template?

My commuter has RD cranks on them and they are perfectly fine, but one session on the track revealed how flexible they really were when sprinting. 75's are much stronger than I am, so they are perfect for on-track exploits but they would be just overkill on a street bike.

RD's for the street
75's for the track

unless you've got money to burn.

yes, RD's for the win.

in Japan the ones WITH the NJS stamp are a lot cheaper. the NJS'ers are silver, the non-NJS (well, rubbed out NJS mark) are the anodized ones in all the pretty colors that fashion demands. and they are about $50-80 more expensive.

Sorry to revive a dead thread.

I have those ****ty FSA vero track cranks on my bike right now, and they have deveoloped play becuase the spider bends from skidding.

Will the RD be a strong eneough crank to be ridden on the street?

my toe clips are enjayess.

i have a set of black suginos. on the inside of the spider it says RD2H TL and on the arm it says 165 Y G-11 forged.

what cranks do i have?
