Do any of you have problems with 'play' in the crank arms? There doesn't seem to be any way of adjusting it out according to this .... http://www.sram.com/_media/techdocs/95-6115-007-00...
I've got mine fully torque'd up and chucked all the grease I can at it. Anyone got any tips how to eliminate it or is it something I'm gonna have to live with?

Sorry, couldn't be faffed with reading all that, where is the play? In the BB bearings or in the crank/spindle interface?
I have no real suggestions to make for either but am interested as a mate has just had to sue for a refund on one of these due to continual chain shipping problems and I'm wondering if this might have been the cause. What symptoms are you getting?

If you hold both the crank arms you can feel the play in both of them so I suspect the movement is between the axle and the bearings.
I very much doubt that the chain slip your friend is getting is anything other than poor set-up. Unfortunately, as good value as the Boardman bikes are, Halfords let them down IMHO by offering poor assembly / after sales service.

Mine and my wife's are solid. Mine has only had six months use but my wife's is over a year old and has had a lot of use. Its not right or normal if you have BB play.
I suspect this is related to the quality of your local store and their willingness to sort out problems. There are plenty of good stores out there. Shop around if you are getting the right quality of service. Also, the Boardman customer services chap (Andy) is very helpful. Just mail Halfords with Boardman in the message title.
It might also be worth emailing SRAM about the problem. I have heard SRAM are also very helpful.

Sadly it wasn't set up, there was something seriously adrift with the thing as it would be absolutely fine and quiet in low pedal pressure situations but as soon as my mate got out the saddle (say), the chain would be straight off whatever chain ring was engaged. It's history now as they eventually paid up (not until a full contested small claims hearing had occurred however), but was a total shame as it was otherwise a lovely bike. CerbitonFlyer said:

built my halfords special myself straight from the box at home....no problems whatsoever...I very much doubt that the chain slip your friend is getting is anything other than poor set-up.

Try going to a real bikestore instead.. you may have to pay a little, but you may actually get better service there..
A quick search around the internet will throw up loads of horror stories from people that did just that. You aren't safe anywhere. The key word is "may". Just keep looking around until you find a good shop/store but don't assume all Halfords bad, all LBS good.

yeah because the teenage spanner monkey in your local bike shop on £6/hour can be trusted with £2k of bike cant he!....as i always say, if you order the bike online from halfords, it will be boxed awaiting collection at the store, take it home, build it yourself and enjoy....

If not, do you have any cycling pals who would be able to watch over / lend a hand?

Hopefully all that monkey does is place your 2k bike in the store room next to their bike, probably worth at least the same as yours, and then go back to staring at their tools, it's not like they know what to do with them, they're only teenage spanner monkeys after all.
Believe it or not, there are actually a number of good mechanics who are still teenagers out there. Yes there's a number who aren't but go talk to them, find out if they know how to do what you require, you may be surprised.

LBS don't have the monopoly of good youngsters. There are plenty of them working for Halford's stores too.Both have their share of spanner monkeys too.

I've had problems with play in SRAM cranks, purely due to my own mechanical incompetence.
The key thing is that the cranks are bolted to each other in such a way that the distance between properly torqued cranks is fixed, a bit like a one piece crank.
If the bearings are not properly spaced with respect to the cranks, then you will either get play (if bearings are too close) or binding (if bearings are too far apart).
So you can get play if the bearings are not correctly spaced or if the bearing shields are not fitted in the correct place and in the correct orientation.
Also, some of the SRAM cranks use a crinkle washer and others don't.
The SRAM bottom bracket documentation is a bit confusing, particularly regarding the use of spacers (which depends on the width of the bottom bracket shell).

And I think this is the issue. Having taken it all apart it appears to be missing the spacer that sits between the outside edge of the bearing and the inside of the left crank arm. I can't understand how it can come out of the factory like this. Can any other of you BTC riders confirm if this spacer is presant on yours?I'm not blaming Halfords for this at all (my comments above where in relation to the guy who was having probs with slipping gears - who I assumed had the bike built by Halfords). I got mine in the box, so take full responsibility for any build related issues (none besides this - and to be fair this isn't something that requires assembly when you remove from the box). I did check the crank bolts were tight, and they were.
Careful on terminology.
The spacers are thick plastic rings (a bit like o-rings) which sit between the bearings and the BB shell. AFAIK they are not required for road cranks on a road bike, I think they're included for MTB installations.
The thinner, smaller black and red things are bearing shields.
