Lets start by me telling you that I installed this ring on my Specialized 6fattie with 27.5+ tires. I went from a 28t round to a 30t oval.
Appearance wise, this thing is gorgeous. I loved it from the minute I took it out of the box. Fit and finish is awesome and its a breeze to install. Looking at this thing mounted on the bike with the AB bash guard is total bike porn.
Now for performance. Dont think that your gonna feel some huge difference. What you feel is that your drivetrain is smoother and your able to spin circles alittle easier. This will definitely help you on flat trails and long climbs. If you ride alot of XC or fire roads, I highly recommend adding this to your arsenal.
So here's the reason im giving this 4 stars and not 5. I cant seem to clean those short technical climbs like I did with a round chainring. Im finding myself spinning out on climbs I never had an issue with. It just seems like I cant control my power output on those sections of trail anymore and its a bit frustrating. Multiple rides on the same trails and I spin out on the same short climbs. Conditions havent been the best lately since its late winter and pretty slick but I will def report back when it dries up a bit.
So to sum it up, its a nice piece. Its amazing on some sections of trails, not on others. At least thats what im getting out of it so far.
*Update* So after a season of riding, I have to say, im really happy with the performance. In any conditions, once you get used to your power output, you will climb technical sections like you know what your doing. Its really just a matter of learning that you might need to be in a higher gear than your used to or you need to really control power output and maybe not mash the peddles so much as spin them! Def going from 4 to 5 stars!
