Deity Problems, Whose fault is it?
« on: July 22, 2008, 07:03:48 AM »

A few weeks back, when i first built up my Revell i bought a deity stem, a white 25.4mm one.
Now when i first got it, the bottom pinch bolt on the back wouldt quite tighten all the way, but enough that when used with the other bolt it would hold good.
When tightening it today, the bottom bolt wouldnt tighten at all, so i tried to tighten the top one enough to hold so i could get to the shop. But oh no! the top bolt has rounded aswell! so now it doesnt tighten at all.
Now, is it a warranty case as it is a manufacturing defect, or is it to take up with the shop?

Honestly, im not very happy, Surely making a stem that doesnt tighten is just retarded?!
Also, i think what the problem is with the stem, is that the bolts are so small, theyre a teeny allen key compared to all other stems ive used. And i think the little bolts has something to do with them rounding.

Whatever happens im going down to the shop today and showing them.

Whats the best way to go about it? And has anyone else had this problem?

I doubt they will warranty that, as they could think you where just hamfisted and rounded them off by doing it too tight..

Your going to struggle with getting that under warranty. What you should have done is taken the stem back straight away when it wasn't functioning properly.
The fact that you've rounded of both the bolts is never going to be a warranty issue, that is purely down to your ham fistedness. What size bolt do they use? M4?

Have you rounded the allen key socket, or stripped the threads?

Either way, unevenly tightening bolts is a massive no-no and you buggering something because of it isn't a manufacturing fault if you've knackered the stem where it could potentially have been sorted.

I'd go straight to the importers in this case, as a shop will probably tell you you're a numpty and ask you to buy a new stem or bugger off.  Explain what you did and see if they are kind enough to help you out

sounds to me like you have un evenly tightened the bolts causing the bottom one to lock on the stem and not allow tightening ....

sounds like you just need to replace the bolts? unless they are a really funky size it shouldnt cost more than a couple of £ for some M5's or whatever they are?

Ive stripped the threads, which is the problem.
My dad is a bit of a dab hand at this sort of thing, he is saying we can drill through and have a nut on the other side of the stem. it would be a decent enough solution, but id have to take the bars off every time i wanted to loosen/tighten the pinch bolts!


Well what im going to do, is go down to the shop, talk to them (i do know them quite well so they should be a bit better), and see what comes of it. The worst they are going to do is say no, they arent going to murder me or anything (i hope).

One was broken from the second i had it! but because it still worked fine i left it. But then it has got worse as both have done it.


Also, after having a proper look, it is a basic design flaw in the stem. It is an aluminium cast, with small bolts pulling on it on a short thread! So of course it will break.
What they should have done, is set a steel nut in the thread so it is steel pulling on steel.
Plus, after feeling the stem, it takes a hell of alot of force to even get the back piece to flex a tiny bit. So excessive stress is being put on the bolts.

It is a stupid design, and im never recommending a deity stem ever again.
When you tighten them, they turn to the left, which is just annoying!
They thread easily (i have spoken to friends and it has happened elsewhere)
And for the money you can get much better! (stem is £45)
Gusset stuff is just as good and is £15 cheaper!

The bars seem okay, but the cranks snap all the time and the BBs are s**t!

Deity stuff has got such a good reputation because it looks so good! Performance wise its no better, if not worse than alot of stuff!

What a load of crap

It's a knee-saving design which is a fantastic thing to have on jump bikes!  And of course you can't move the sodding thing by hand.  That's why the screws are there; mechanical advantage! 

And on what basis do you say the cranks always snap?  I've heard of a fault with one set, which was supposedly the first ever sent back to Deity.  The mk1 sets got rave reviews for being one of the finest, best executed cranksets on the market.  And anyone who buys stuff just because it looks pretty wouldn't appreciate that anyway.  I love mine to bits even if lighter, snazzier cranks are available.  They feel solid and I wouldn't question their reliability.

Deity are a decent, rider-oriented company.  See what they have can do for you, but don't start slagging off their entire range because you mashed a couple of stem bolts

If your going to do anything heli coil it don't put a nut on the other side. It will just look bad.

If your dad was a "dab hand" he would suggest something a bit neater than that...

What they should have done, is set a steel nut in the thread so it is steel pulling on steel.


Thats how 99% of stems are, its not a "design flaw" its you being hamfisted with an allen key.

A thomson seatpost has small bolts on a small thread, that must be a stupid design too. C'mon thomson owners, send 'em back!

drill the bugger out and tap it with a larger sized thread.

hahah timL you should be a design engineer .....

your ideas cause all sorts of problems during manufacture

like i said ...you state one bolt was broken before you started but

if you tighten bolt 1 as tight as it will go ....bolt 2 will not move as it is binding on the resess

and bolt 2 will be very tight

thats why you should tighten a bit at a time in a 1, 2 ,1,2 rotation

Fixed for you
The only flaw is with your logic.
