Steel X-Sync Rings from SRAM for Under $20

 I agree with the brakes and chainring but I really don't see anything better about the new lyrik. I would still prefer the old one, just my opinion though.

 My drama brakes are junk

 I was in whistler renting a v10 which had the Sram guide RSC. had the bike 4 days had to replace two brakes. It was no big deal as the bike shop swapped them out asap. I was ticked off because I had purchased the guides for my new build and was hopeing I would love them. Made the switch back to my XTs yesterday. Better brake at half the price.

 You know you did a good job the first time when you release the new version and change almost nothing in order to stay competitive. The XT brakes are one of the most solid components for the money in the mountain bike world. You can get a set for barely more than what some flat pedals cost.

 If you think this is for you, then you just admitted to fitting their profiling. Considering they only made it in 28-32t, they must think that those interested in a cheap chainring can't push a larger gear.

 @ninjatarian: until the Pistons crack

 Was curious about the weight of them until I saw no 104. Doesn't matter now.

 Haha they aren't going to let people with the top groupset cheap out on them

 XX1 has a removable spider so the DM works. You just have to remove the crankset to put it on so you will lose the advantage of swapping rings quickly.

 @Lastpikd : but the only one size available in DM is 28t!

 @rrsport - X01 is BARELY cheaper than XX1 and they make a ring for it (94bcd)

@Lastpikd - yes but who the hell wants a 28T? At least make the most common sizes (30 and 32) also. 28 is so unnecessary with the 42 cog on the cassette, that's a lower ratio than most 2x10 setups offer.

 @Alias530 Hardly unnecessary, in places with steep hills particularly riders on 29ers, there are a lot of 28t chain rings on bikes

 I don't know about you guys. But I think you guys are strong. Either I'm not strong enough or I'm doing something wrong. My setup is 28t and a 42T oneup [1x10]. I used to have 32t but it was too painful. It was hard to sustain more than 1200m (about 4000feet) a day, everyday non-stop like for an enduro trans-alp adventure. One the 3rd day, my legs get fatigued out and I won't be able to continue.

For one day tours, I could mange with the 32t up to 2000m of climbing. But if it went to consecutive days non-stop for more than 4 days, my legs died. I bought the wolftooth 28t direct mount gxp (even considered their 26t) and so far I'm very happy. I have to admit on one day rides or first day of a long multi-day tour, I hardly use the 28t x 42t combination or maybe not at all. In the succeeding days where muscle fatigue starts setting in, I find the lowest combination very handy as it allows me to just keep pushing on. Btw, my bike is a Canyon Torque. It's rather heavy for an enduro bike, almost 16kg.

 Chainrings aren't covered by warranty (unless it's a massive failure that can be proved was the manufacturers fault) SRAM say that no wear and tear parts are covered by warranty - this includes stanchions just to give some perspective on how comprehensive the ts and cs are

 I'm interested to see how they stamp a narrow tooth.

 Not too complicated to stamp something with varying thicknesses, nor would it be hard to do a quick machining operation at the end to finish the teeth.

I'm curious what this will do to a chain, sure the chainring will last longer, but what about wear on my $60 chain which in turn wears on my $200 cassette. I think for the time being ill stick to race face or one up, cheap enough not to worry too much about replacing them every now and again.

 Interesting that aluminium is cheaper to make and cheaper to work than steel, but these are being marketed as the budget option. The margin must be low on the steel one, and I bet they hardly sell any. I would not buy one with so many well priced alternatives on the market from smaller brands. Spread the wealth.

 Steel chain rings should elongate the life of the chain. The primary reason for chain wear is that the sprocket wears out, which in turn puts more stress on the links of the chain.

 Relatively soft steels are also typically used in the stamping process, so don't be surprised if the durability isn't really much better than a 7075-T6 or T651 ring. Would be at least better than untempered 7075...

 They won't work with your crank because of different BCD. Your crank have 104BCD but these are 94BCD. You can pick from Hope, Race Face, Wolf Tooth Components, e-thirteen, Aerozine, etc.

 I don't recall the BCD of X1 but X01 is 94bcd so these will fit it and the direct mount 28T fits anything with a removable spider. Too bad they aren't making a 30 and 32 direct mount version.
