I've got an '05 Norco A-Line and Im throwing a new chain guide system on it. However, I'm torn between an MRP World Cup 1 or 2, and an e.13 Single Ring System. Any requests? I can get them both for about the same price... [$82]

just wanted to point out another light weight model...sorry if you're not interested.

i have the e.13 too...however i was looking to expand my horizons. the e.13 has been great, but i was looking to lowcelize my new build a little.

the gamut is the lightest one out there. however, that does not come without cons. if you plan on bashing into and casing everything in sight, you might want to stick with the two you mentioned. if you are more of a finesse and calculating type rider with an occasional bump 'n grind who wants a solid derailment device, i think gamut could be for you as well.

e13 for sure, i have it, love it, and theyre industuctable

For a 38T chain ring would I get a 40T SRS system??

that should be fine

e13...

the other one I am planning to play with is blackspire. The system is SOLID!!!
