Even if the shop isn't helpful, how hard is it to look up the product page, find it uses M447 calipers and google for compatible pads?

A bike my have faults, but you've at least got to be fair.

I am being fair. Ive had the bike for 12 months. The spec of the bike for the money is great.
But all the niggley faults due to poor build.
Having to replace the crank at my own cost. (Even though l've got a 2010 Cube HT on it's original crank even though it's had a tougher life to date).
Popping into the shop to buy parts only to find that I've wasted my time.

My personal experience of owning my Bossnut will differ from yours.

I can see what you are saying, and I do actually understand the frustration but a poor build is not the fault of the manufacturer but the mechanic who built it. A frame defect would be different...
Staff not knowing much about the products they sell is nothing new for any store, some staff will inevitably be more knowledgeable than others (also take into account what time of the day/week you go in, an hour before closing time may only be part time student staff whereas lunchtime on a Saturday may be much better).
Also you do need to remember what Go Outdoors is, it isn't a specialist mtb or even cycle shop, its an outdoor superstore. Not stocking parts that the vast majority of their customers wont go in to buy (and fir themselves) is not a surprise. Plus if you know you need them you can get them online for instore pickup.

To be fair to Go Outdoors, they do carry a reasonable stock of consumable bits that I wouldn't associate with every store that sells bikes. They don't have as good a range as Halfords, but still not bad. Don't know if the Bossnut uses brakes / pads different from the other Calibre bikes they sell, if it uses the same as the Two-Two etc it would surprise me that they didn't carry them.

BOSSNUT.DAVE

why is everyone focusing on the brake pad issue. That is just the last thing to have happened. I'll get some pictures together of my failed crank with some measurements and you can decide. I have a test go with this one.

Was the crank faulty or just came loose? As with all these 'big brand' shops, you have to be aware of these things. Owning a Boardman, I'm fully aware some people have had bad experiences with certain Halfords stores. But it's an issue with the stores, not the bikes.

On my first ride out the rear wheel dropped out of it's mounting. I simply refitted and tightened up the QR a bit. After this I checked the tightness rest of the bike. Everything seemed fine.
Soon after this I went up my local woods, which I know extremely well. Bearing in mind that I have checked the tightness of bolts! As I was getting into the swing of things and started to push the pace on, the handle bars give way as I loaded they up with "normal amount of" force as I rode over the tree root. Pictures will help.

I'm not new to this, I know exactly how to ride over this. but the bars just broke their gripping force. I was completely caught out and fell on to the rear mech with my shin.

Go Outdoors were unsympathetic, The cause of the bars letting go was due to grease between the stem and fork tube. They didn't replace parts, but simply bent the rear mech back into line. I still think the mech hanger is bent out of alignment.

Then the pedal arm.
The first time it just drifted left, it didn't go wobbly. The preload cap just fell off at the same time.

I took it back to Go Outdoors only for the tech to refit it back on.

It came off again on the second ride, so it only stayed on for about 15-20 miles.

I took it to LBS who said it was strange, They refitted it but weren't optimistic that it would stay on.

Then the GO shop had lack of components parts.

Here are the dimensions of the failing crank.

how the end looks at the above spacing, how does the reload cap reach to screw into the crank threads?

There you go it only uses the end thread.

Forgot that the rear shox has just failed also. rebound adjuster + - has locked up.

Parts fail, but ffs Dislike the Bossnut,
The Cube in the back ground has been bullet proof, for 7 years.

I'm still not understanding the problem. It's a Shimano HTII crank. I have the same thing on four bikes (Deore, SLX, XT and a slightly older LX) plus a few Deores lying around, because it's pretty much as cheap to buy a new Deore crank with BB as to replace the chainrings.

I've been using them for years, and have never, ever had one come loose.

The preload cap is just that, once the pinch bolts are done up properly (alternative bolts, bit by bit), it's pretty much impossible for the crank to loosen. It even has a little plastic thingy for added security, or so they say.

So either the wrong spacers have been used for the BB size, or someone doesn't know how to tighten pinch bolts.

The cranks themselves are about as bombproof as you can get. And are used on millions of bikes.

Edit as you've posted since I typed, you seem to have problems with components, that loads of other bikes use as well.

BOSSNUT.DAVE

I completely agree Cool Dad.

I thought the same about fitment of the crank/pinch bolts thats why I took it to a MTB shop that sell Santa Cruz, Cube Nukeproof etc.
They said the Deore crank looked fine. Fitted it and said "there you go you'll have no problems now." Wow it slid off to the left. No wobble just Bam it's off under load.
It's the only cycle/motor bike that I've ever had so much trouble with.

It does seem odd as CD says these are decent quality, branded parts used on a million bikes. But I must admit the Bossnuts seem to have an issue with particular things. The cranks and shocks especially.

I'm of the opinion (because i can't believe two shops can be wrong ) that these Bossnuts are cheap because they are made up of parts which have a more relaxed quality tolerance.

I've made contact with Mike Sanderson on Calibre's face book page, he was helpful in respect to finding where to source a rear mech hanger at £34. But once I started talking about my crank problem, he stopped replying, but you never know he might be busy doing other things and out of internet connection.

Shimano aren't going to supply branded sub standard parts. It's just not happening.

So it's down to the original build?

BOSSNUT.DAVE

I've made contact with Madison Uk Shimano agent. They are wanting the item returned so they can understand why it's not staying on the bike.
Only problem is i can't send it back, LBS said they are happy to teturn it on my behalf. But I'll give Go one last try to help out.

Could the crank issue be stripped threads on the two pinch bolts so they are working loose? Would tie in with it working loose but the crank and the spindle looking OK?

Like your thinking, but the pinch bolts seem fine and are still tight. The arm can not be put back on until they have been undone.

Not had any more luck. When i went round Llandgela I had a turn of speed and got air over some table top jumps. The rear tyre rubbed the frame on landing. Rear shox is set to 25% sag and rebound mid way.
Few days later I went up Eastridge in Shropshire and the fork lock out function failed, i can no longer lock the forks for the fire road climbs.
I contacted M i k e Sander son via message from calibre s FaceB page. He offered to give a full refund so after all the niggly problems I'm more than happy to take him up on the offer.
