Brand new bike and has this SRAM X1 on it - SRAM feels terribly cheap and nasty compared to XT - shifters feel utter bobbins and the last jump to the biggest cog appears to be hit and miss - to get the chain on without a massively forced push of the shifter, the chain jumps off into the spokes...adjusting the mech so it doesn't means it won't jump into the largest cog - so I need to make sure I don't push in haste or anger.
That isn't the real issue though - the rear mech will not drop down to the 11th cog...the limit screw has been backed right off and there appears to be slack in the cable so it isn't stopping the mech move - but it just won't go...is it because it is new and needing a stretch/bed in?
Loving the rest of the bike, but I'm already thinking the 1x11 and SRAM stuff was a major mistake!
X1 is super sensitive to b tension (with an added twist). Gears 3 > 11 are sensitive to the mech b position (a-la the 42T issue you have) whereas 2 into 1 has a different issue which is that the mech arm will foul the looping cable run at certain angles, meaning you have to set b-tension to avoid that... not as easy as it sounds when on an FS as the arm moves about. Once you get there though it will be good - different to Shimano for sure, but good.
Internal cable routing so no fouling of the cable...I talk about 11 as in smallest cog, 1 is largest. So when shifting into 1 (largest) it isn't a smooth shift and very capable of being thrown in to the spokes...11 just isn't going...I need to do some reading on how to set it up!
I'm calming down now...I'll get used to the feel and I'll spend some time working on the mech.
I'd be a bit annoyed if I got a brand new bike with the gears not set up properly - what about whoever you bought it from??
You miss understand DickBarton - the fouling is he mech fouling [i]itself[/i]. Look at it in 10T and you'll notice that likely the arm catches the loop that takes the cable from the pulley to the front of the mech. (Simple test - in 10T move the arm down and see if it clips). This means that when the arm is trying to tuck up to go from 2 > 1 it can catch that causing issues.
PS - I did actually get the gears you meant as both things you describe are common set up issues I find so it made sense. I just wrote my response with the terminology the other way round... doh.
Ok, the b-screw appears to be about 1-2mm away from touching anything in highest and lowest gear i.e. largest sprocket and second smallest. There doesn't appear to be any more movement in the mech and I can't work out what may be fouling the movement.
This clutch thing is also causing me issues as I've no idea how it actually work...I'm going to ride it into work tomorrow and see if things start working...otherwise I'll do some youtubing and see if I can find a how-to video guide!
Thanks for the info...however I'm stuck on what it actually means!
I'm thinking the bike was setup fine - no doubt on a workstand rather than having someone riding it around...it wouldn't have been allowed out the shop if it wasn't working - suspect it is me not knowing how SRAM works as I've been riding Shimano the last 20 years...also the new setup isn't familiar - 11sp...
no doubt on a workstand rather than having someone riding it around...
And therein lies the problem - on a workstand the mech is in a theoretical position it will rarely ever be in again so it needs setting up to be ridden not on the workstand, which is where the problems start. When I get the next X1 build in a stand I will take a picture of what can catch on what for you.
Nice one thanks...
The main part of the mech (that the cage attaches to) - doesn't seem to move...the b-screw is fully screwed in...no more room for screwing in further...so if the main body is needing to be moved away from the cassette, then I'm unsure how to do that now (for now!)...
Just read the installation instructions... The mech was setup as per the guide...so looks like it is maybe needing ridden and bedded in...will do that on way to work tomorrow.
If that fails, tomorrow evening will be spent working on it!
Think I've found the problem...mech appears to be hitting the frame.
Looking at the mech, the top part (horizontal piece where the parallelogram is) doesn't move...so I'm unsure what the b-screw will do if I can screw that in more. It looks like the mech needs to be adjusted to move the top jockey wheel down so it isn't fouling against the frame...
The chain also appears to be 'slack' when sitting in the smaller gears...almost like there isn't enough tension in the mech...
FIXED! It looks like I've somehow managed to bump the mech and rotate it forwards. Think I need a wee adjustment of the cable to get the gear changes sweet.
Sheesh. X1 is fitted to the bike I've been toying with buying, and I already had my reservations. Sounds like it's quite temperamental! Wonder when the new 11sp XT will be available.
2016 - according to the reports...so more like August this year!
I've recently built a bike with XO1 and was apprehensive as I've always fitted Shimano parts until now. However, it all went together easily. I got the shifting into the ball park on the stand and then tweaked it during a test ride. Once in the zone the shifting became precise and consistent. I was pleasantly surprised and now am impressed by the groupset. Stick at it!
Best shifting I've ever had and I've had them all, currently using xx1 shifter x01 mech and x1 cassette truly awesome. Now you've got it setup just use it you'll love it just remember a good clean and use a really good lube. Was advised by sram mechanic to use much off c3 ceramic dry.
According to MBR 1x11 XT will cost about 410 quid for the complete groupsets...which looks much better than the 240 quid just for the X1 cassette!
Gears are running sweet now, I need to double check the bolt on the dropout as the mech can still move forward and then stick...
I use Pedros Dry Ice chain wax...has been very good.
But it's more comparable in weight and price to GX. The X1 cassette is the best part of 100g lighter than XT.
And the XT cassette is almost 200 pounds cheaper...so it instantly makes XT seem the better option in terms of running costs...for the price of 2 x1 cassettes, you can have a full groupsets AND change.
However XT isn't out yet so isn't quite the same...will give SRAM time to hopefully drop the prices...
And for shimano to actually come up with a comparable product. Same number of gears not the same range.
And the XT cassette is almost 200 pounds cheaper...so it instantly makes XT seem the better option in terms of running costs...for the price of 2 x1 cassettes, you can have a full groupsets AND change.
You misunderstand my point. XT and X1 aren't comparable. X1 costs more and weighs a lot less. GX and XT are the comparable groups in price and weight. The SRAM hierarchy is a red herring. Don't think of GX as 4th tier, and therefore Deore. It's not.
ok...but why would it be a red herring? Or do you mean the different levels of groupset between the 2 manufacturers are comparable as like for like on a paper list of the names?
SRAM's hierarchy isn't as linear as Shimano's - people look at it and say 'aah, X1 is the 3rd tier groupset, it must be comparable to SLX, and it's really overpriced'. It's actually, in the main, lighter than XTR. X01 is lighter than XTR, then you've still got XX1. You're doing it here - X1 cassettes are expensive yes, but they're lighter than XTR which is a similar price. It's not an XT rival.
You can't draw a parallel between the two that neatly.
Interesting...I hadn't studied the differences to any real detail so had assumed a linear approach...hadn't known the weight savings...
Just back in from a ride...it works very well indeed and has been the quietest I've had in many years...someone was right - when it works, it works very well.
Like a said bud used them all including new shimano xtr 11 speed and my setup is definitely the best I've used perfect range for me as well. Enjoy
Glad you got it sorted. I'm still impressed with mine and am beginning to take its excellence for granted.
