Their recall issues have now spread to include quick releases

Not sure I'd like to go back to any SRAM gruppo

They're having a bad run of late........surely, after all this drama they have implemented more robust testing procedures and stricter quality control checks

as for myself
very happy with DA 9000 and XT 2 x 10
1 by is definitely of interest.......leaves more room for the dropper post & lock out levers

I have a better idea. There is plenty of chatter about these 1X systems suffering from chain drop, and needing chain guides, not to mention limited range, big gaps between ratios and the comically sized sprockets at the back.

Why not have a moveable chain guide just behind the top of the front chainring? Control it with a lever incorporated into the left-hand brake lever. What you could then do, is have a smaller secondary chainring inside the main one that you could deliberately de-rail the chain onto for climbs and such. With the smaller, secondary chainring (and perhaps even a smaller-still tertiary chainring inside that one) you'd get away from having to have a very large sprockets at the back, as well as having far more gearing options than are possible, even with 12 sprockets at the back. A wide range, and close spaced ratios. Wow. Your rear derailleur also wouldn't have to be as extreme in terms of geometry and cage length either. Cheaper, lighter and probably shift better too. It'd be great. Nah, it would never catch on.

1x for MTB makes sense, but this is getting silly. One of the major pluses of 1x was running a short RD cage which kept it clear of obstacles, that Eagle cage looks as long as Shimano long cage.

People are saying this will be great as you can run a 36-38T up front and still maintain the low gear range. Sorry, but if you can spin up a 38x10 you need find some proper MTB trails as you're riding downhill on a fire road.

I think spam does this for 2 reasons..

they can't make a front der and this will reduce future recalls..

ANOTHER in season intro that makes any and all 1by11 bikes on shop floors..obsolete..

 

[JackRabbitSlims]

the comments section under the article is a funny read

for example: -
Wrong, I am 41 and run a 11-28 on my 29er with a 36t chainring and I feel like I need a tampon for not running a 40t. If I leave the piedmont and ride in the blue ridge I put on an 11-34 and call myself a pussy. Everyone needs to ponder rule V before buying this crap.

Before I bought my new bike in October, I tested 1x to see if I wanted to go that route, and it just didn't work for my needs like 2x. Also, the chain lines created by 1x are pretty extreme which does lead to some drops/ghost shifting, and has to add to chain wear. SRAM has moved the second chainring to the cog set.

Agree with most of what you say - although 1 X is definitely suited to certain types of riders.....I've just started riding with a new crowd on Tuesday nights at our local MTB park (with full lights from 6pm) most are hauling 1 X....unsure why TBH?.....the trend is definitely swinging that way and minimal /simplicity is attractive....as for myself and the type of riding I'm doing right now...I actually need 2 X 10 and use both chain rings a lot!!

Hard not to get caught up in the hype and "fashion" of mtb riding....it used to be super simple and real straight forward.....nowadays, it's getting quite complicated with loads of options (perhaps too many).....the last thing we need is suit-marketing-sales-douche-dudes making the decisions on where mtbing is heading.

Please remember that guys and and gals used to / and still rip it on 26", Alu Hardtails & Rigids.

I have fond memories of all of my dirt rigs (dating back to '87), but that doesn't mean that I want to ride them now!

If your bike park is like ours, a 1x is fine because you only need three gears. The cool part is my 2x11 has those three gears on it, but I can also cover every other terrain that I ride with out compromise. Two guys who I ride with frequently have 1x and there is compromise. As long as Shimano keeps making what I need I don't care what anyone else rides!

This, I can agree with.

the trickle down effect..... http://www.bicycling.com/bikes-gear/news/first-look-shimano-xt-di2-electronic-group-with-wireless-connectivity

i come off my MTB way too much these days to think about spending all that $$ on shifting

happy with XT Mechanical and 2X - suits my needs and budget for the time being.

SRAM's new cogset is 10-50! A 50 tooth cog?!

Re:

12s, XD driver, makes a lot of 11s obsolete..and it ain't cheap either. Not surprised, as I've mentioned, front ders and sram are a contradiction.

Re:

Less range of gears with bigger gaps. Isn't technology great

Saw an overweight 50 something riding an S-Works Allez with a SRAM single chainring setup on the weekend (complete with about 30mm of spacers and a riser stem). Poor guy looked like he had no idea what was going on, he was obviously a very new rider.

Whoever sold it needs to be slapped.

2 X 11 or 2 X 10 no single ring mtbs for me. I often ride the road to the trails so I need a range that goes from road to steep. A 10 or 11 wears out fast leaving the cassette worn out for 1 or 2 cogs. Spacing is too wide for the road or trails. then there is that pie plate.
Maybe if I only rode the bike on trails

I see a lot of that here. I think its awesome when people with money buy $10K bikes even if they don't ride them much because that's more money in the till at my LBS. They change out a lot of 1X for 2X: sometimes before the bike leaves, and other times after the rider realizes that the shop was correct that the 1X gearing is tough on some of the grunts.

I've also noticed an increasing tend of $10K bikes with DH/BMX flat pedal, and people wearing their jogging shoes. Again, more power to 'em. These people are why my LBS can afford to give me discounts!
