As above what's the difference between the two, Weight, performance?

I have some Pre 2008, Martas and Marta SLs. The difference is carbon lever blades on the SL and (I think) lighter rotors. I say think because I think I got the SL rotors on a set of Martas.

I think this is also true of post 2008 models and there is the SL Mag which has magnesium calipers.

From a performance perspective they work exactly the same.

So the Sl is really just for weight concious XC racers. Cheers, I will go for the standard marta's then!

Sorry about the multiple replies. STW hung on me.

I don't think there is a much weight saving on the SLs over the normal version. The standard Martas are pretty light as it is.
