I have a E-thirteen Lg1 chain guide on my DH bike (flatline) but I'm not so happy with it, I broke twice the little piece that holds the pulley and a few days ago I snatched both lower parts...
So my question is what chain guide is stronger or better enginered ?
Of the two you have shown I would take the blackspire for toughness , one of the gamuts selling points is it's very low wieght as you can see from the skinny back plate. If you can get hold of the older E-13 devices with the full bash ring they are tough as hell.
One more question, will this blackspire fit to my flatline, with a saint crank ? I readed somewhere that I have to watchout that it s compatible, is it ?
