SRAM s300 cranks

Anyone riding them? They look pretty solid, and i like the idea of the external bearings, but can't find anything on the chainline on tinternet. Anyone know anything about these things?

awakening the dead here: no one knows nothing about these cranks? s300 or s100

Been looking at these too - priced about mid range and they look great. Anyone riding?

I dont think so.

A quick google and these appear like road cranks to me.

I've recently got and fitted the truativ omniums which are mid(ish) priced track cranks with external bb.

They seem nice and stiff so far, were easy to fit and spin nicely, the chainline seems fine with both on one and bontrager track hubs (so I assume 42mm) but without measuring it the q factor is a lot bigger than my campag record pista cranks.

A friend of mine has the s300's on his mash frame, not sure on the exact chainline measurement but the clearance is super tight.

This is the problem with external bb's, you are stuck with the axle length of the crankset.

It shouldn't matter as it gives a correct track chainline...

^that was exactly my concern...but they do come with a single ring. they have a 1.1 version of the s300. I might get it to see how it goes with my primato hubs

I have these cranks on my Nelson Pista. The chainline is 42 mm, and they are made for one chainring. It's only 3/32" though, so you might want to change chainring.

^your refering to the s300 1.1?

Yes, that's right.

brilliant! thats all I needed to hear!

post a pic please! thanks

Not exactly light though.

the road one (with 2 chainrings) weights 900grs, with BB. the omniums weight 825grs.

All I have is this old photo from when I built the bike last summer

The cranks weights 860 grams with BB on my scale. Pretty light for the price I guess.

cool! wanna sell me yours? ;)

just got mine! switched to cheap smaller chainring until I have funds for a 42t one.

Factory fitment on lemond filmores, nice cranks. Nicer than srams imo.

Hey everyone, sorry to revive a dead thread but I'm trying to upgrade my bike and I'm very confused. I bought a pair of Mavic Ellipses, not knowing they had a weird hub spacing. I can't even figure for sure what the spacing is (44 or 46?) over the internet - haven't received them yet. I've also been considering the S300 cranks, and again I'm getting conflicting answers (41 or 42mm?). I just want to know if I can set up Ellipses and S300's to work together properly. Or should I consider a different crankset? I don't have a head for mechanical things, so if someone could bail me out on this I'd be thankful!

...I bought a pair of Mavic Ellipses,...

I think to have bought Mavic Ellipses in the first place, shows some particular and technical knowledge.

Here are some examples of crankset combinations with Mavic Ellipses.

Example 1
Example 2
Example 3
Example 4

Its up to you to decide if you continue with SRAM 300, or maybe something else.

There's lots of options.

Thanks! At this point I'm just going to try the S300's and see if they work out. From what I've been able to gather they are similar in setup to the SRAM Omniums, which seem to work fine with Ellipses.

Internet searching has only confused me. According to various sources, the Ellipses are either 44 or 46, the S300's are 41, 42, or 43, and how much of a difference in width is acceptable/unnoticeable varies wildly. It's insane that this info isn't easily available on the manufacturer's product websites.

46 sounds a bit large for a track wheelset seeing the 'standard' is 42.

Best bet would be to measure the chainline on the rear wheel as you physically have the wheel then you would know for definite.

Chainline Measurement-Rear (For bikes that do not use derailer gearing)

To measure rear chainline:

• Measure the frame spacing (or the over-lock-nut dimension of the hub , which should be the same.) (Example: 120 mm)
  
• Divide the result in half. (Example: 60 mm)
  
• Measure the distance from the inside of the rear fork end (or the outside of the axle locknut) to the middle of the sprocket. (Example: 18 mm)
  
• Subtract the dropout-to-sprocket spacing (Example: 18 mm) from the half-over-lock-nut dimension (Example: 60 mm) to determine the actual rear chainline (Example: 42 mm)

i've got the s 300 1.1 crankset on one of my bikes - 42 mm chainline
