currently running a three ring set up, ive been suffering with the chain getting intimate with the bb for far to long, its time to end this sorrid affair!

ive been weighting these up;

any one with any experiance of these or similar?

do you notice any extra drag?
are they high maintanence/ clog up with filth?

with losing the big ring i suppose it would make sense to run a higher gear set up to?

hmm, I was considering one of those but was thinking that it must be quite easy to spin-out a middle ring on long, fast descents?? How do DHers get away with only using a "middle" ring?

Don't really use a middle ring, Dan. It is on the middle ring tabs on the cranks, but most guys are running a 38 tooth with a road cassette. I'm using a 36t for extra ground clearance, as my BB is lower than a monkeys knuckles and that lets me use the smaller bash guard.
For a twin ring setup I'd go with a 36/24.


E-13 do a dual ring chain device, I've never used it but their single ring devices are amongst the best there is.
I dont see too many Blackspires around these days, though I have used them in the past and they were fine.
One problem I had with them was the Allen bolts are all Imperial, that may have changed now tho'.

e13 worth the extra 40 notes?

E-13 is worth every penny, was going to go for cheep option, but changed my mind. I run just a 34 tooth front and find that is fine for almost all riding

cheers all, will get the e13 drs when ive got some cash, and if it ever stops fookin raining..
