Enduro? Piece of ****?

I got a new Enduro Trail today, or the green one. The first time i switched to my high gears or 1st gear the chain came off the crank and twisted itself and had to be replaced. Have any of you ever heard of this before? The bike shop said they had seen it happen before and it has to have time to break in but for $1700 i think it should not do this.

Operator error. You don't shift under pedal load.

Haha wow that was a good one huh. This happened with minimal stress on the crank on a paved road, on flat ground.

It wasn't the bike. As much as you want to blame it the fault doesn't belong there. It sounds like operator error, I get stories like this come into the shop about once a month. Heck I even did it myself on my hardtail. The fact of the matter is that you shifted a handful of gears under load and that's why you mangled your chain. It's not the bike's fault.

But you arentunderstanding there really was no pressure or load. There is no reason for me to lie here.

Perhaps there was an improper adjustment made by the shop. Regardless it's still not the bike's fault. Heck I'd defend a Walmart special on this one. Have them replace it with a SRAM PC 59 or better and have them double check their adjustments and run you thropugh the proper operation of the shifters while they're at it just to be safe

invest in an e.13 drs (if you got two rings up front). you'll probably never drop your chain again.

It definately was not the bike's fault. I imagine it was just poor adjustments of the derailleurs. Otherwise I would say it was rider error but you say there was not much stress so that pretty much rules out operator.

Maybe the operator was still used to his old coaster brakes and accidentally pedaled backwards throwing the chain.

I have not had my chain pop off but I'm curious as what is defined as proper shifting technique. Can we shift while pedaling? I have read references to not shift while standing on the pedals. Does this mean no shifting while literally standing on the pedals or does this mean no shifting while the pedal is on a downstroke (vertical positioning vs horizontal positioning)?

Does this mean I should be coasting and then shifting?

I have Deore components and have had no problems shifting up (tall to short rear sprocket) but when going the other way around I occasionally feel my cadence accelerate as if there is no load for a half second and then get re-adjusted to the cadence I was at before. Is this an indication of poor shifting technique or of an improperly adjusted derailleur?

By not shifting when standing it mainly means while applying a lot of pressure to the chain. It is best to kind of lighten up on the pedals while shifting. Always shift while pedaling though.

Good idea but not needed.

Enduro is a good bike, just needs to be broken in. Stop complaining and give it time.

Jeez..the guy only missed ONE space.

Is this true? Drivetrains need to be broken in? This does not seem to make sense considering it is all mechanical, shouldn't it be more precise when new and only loose it's precision as it wears. (although very slowly)

I understand other things needing to be "broken in" like break pads, or lubricated parts, but I don't see why a new drivetrain would need "breaking in"

I was just riding along and...

I don't see how its possible to twist a chain in ANY circumstance, unless force was involved, derailleurs properly adjusted or not. It sounds like operator error, maybe coupled with a derailleur adjustment, but force was definately involved if a chain twisted.

Anyhow, it's not the bike's fault. It's either a problem with the drivetrain (Shimano) or just bad adjustment or bad shifting technique.

I'd put my money on one of the two latter choices.

Drivetrains don't need "breaking in" the only thing that "breaks in" are the cables and that's more of a slight stretch issue that's easy to adjust out.

That's what I'm saying. That's how I screwed mine up a few years back. I did something dumb and it came back to bite me.

Ohhhhh, geeze a loo. So crappy components or not, don't shift under drive train load?

yeah when I'm climbing and standing I shift and the sound that accompanies this makes it sound like my bike is dying.

I've had chains do evil things when only shifting ONE gear under load

Eh? I can only shift one at a time...At least I think I can only shift that many at once.
