ScotchDave Posted June 21, 2005 Report Share Posted June 21, 2005 Good thing I run a shitec then. :D But wouldn't you expect roadie stems to be weaker, cos they don't have to be as strong so can be made lighter for weight saving? :P Quote Link to comment Share on other sites More sharing options...
iatola says Posted June 21, 2005 Author Report Share Posted June 21, 2005 I run it because of the geometry works and has improved the ride over the maasive, retro brisa stem i was running Trev Quote Link to comment Share on other sites More sharing options...
Tomm Posted June 21, 2005 Report Share Posted June 21, 2005 Guess Road Stem. Echo Control Trials Stem. Same thing :D ← Bloody hell :P I *hope* that's a massively overbuilt road stem. Quote Link to comment Share on other sites More sharing options...
Mark W Posted June 21, 2005 Report Share Posted June 21, 2005 Neil Tunnicliffe is the only person I've heard has snapped them. Thought it was you who told me Ad? :) Anyhoo, yeah, confused the tats off me when I saw someone running an upside down Guess road-stem at the Deej ride, but they too assured me it was also moon-lighting as an Echo Control stem. Little sketchy, but they seem to hold bars in front of you I guess so who's fussin'... Quote Link to comment Share on other sites More sharing options...

Thought it was you who told me Ad? :D Nope, definitely wasn't me :) As far as I'm aware, Neils never had a set of those. May be wrong about that though.

Had it for getting on for a year. Quote Link to comment Share on other sites More sharing options...
Siders77 Posted June 22, 2005 Report Share Posted June 22, 2005 I swear it was Dan Brisa that snapped a stem, doing a rail gap. :) Quote Link to comment Share on other sites More sharing options...
MSM Posted June 25, 2005 Report Share Posted June 25, 2005 Hi Iatola, the equation Force x Distance. If you aplly this to stress on bars, especially on high BB bikes where you ride over the front alot then the stress on the bars is far greater because you have 14/15" of leverage each side. Now a stem is much shorter than 15" at least on stocks. And stems can be made from Carbon Maybe I have missread your what you are trying to say here, apologies if this is the case, however it seems that you are suggesting that the stem has an easier job than the bars in terms of force transfer. Okay, the bars are longer than the stem, but how does all the force applied to the bars get transferred to the frame? The stem is the only route through which the forces you apply to the bar ends can be transferred to the bike itself, if you discount the forces that transfer through your body between your hands and the pedals. So when you suggest that each bar end has, say, 15" of leverage to work with, then surely the stem will be having to deal with the forces resulting from this leverage advantage multiplied by two bar ends, if that makes sense.

Bucky Posted June 26, 2005 Report Share Posted June 26, 2005 i snapped the monty urban stem last year. and have snapped about 4 sets of bars too. but at the mo in running a raceface prodigy stem (about 4 years old now) and having no problems with it.

Littleharrys Posted July 1, 2005 Report Share Posted July 1, 2005 That is EXACTLY what happened to mine on my DH bike, also last summer, apart from mine went from the bottom upwards when I did a 3 foot drop. It was truely confusing as to how it happened, considering the force was going downwards, and the stem broke upwards, held on by a slither of metal at the top of the stem, which suddenly went solid-feeling again in the new position. Hard to explain, but it was freaky. ← Yeah I was pulling up for a backhop, it was held on with same slither of metal as you, just the top flat bit. Harsh.

Hehe, that was probably Bigman? I used to run the same stem (well, a 100mm, not a 120). Had it for getting on for a year. ← And I believe that is the same stem which I still have and abused for several months afterwards? with the black tape over the Guess writing? Brilliant stem. No reason for it to be weaker becasue its a roadie stem, stems are stems, all properly made stems will be made to withstand the same forces. there is no such thing as an ultra strong 'trials' stem as far as i can tell? *(1) As for carbon stems... why not sounds good to me, I belive in carbons ability. seeing as i've spent so much of the last twelve months making and braking the stuff I have a fair idea of its capabilities. Im sure if the moeny and time was spent on it a good bondnig sytem could be found for the ally inserts. the technology alredy exists thats for sure. The real issue would be wether the right carbon weave and resin system was chosen by the manufacturer (they won't make it themselves from scratch), as if they got that wrong you could see some prototype snappage :( (1) by properly made I mean: not a crapily cast stem made from low quality aluminium alloys etc....

TrashZen Posted July 1, 2005 Report Share Posted July 1, 2005 Looks like Trials riding can be risky then? :( What about having amazing mental condition, if you can't trust any bike part? :P Oh, just have to pretend it never happened, like chains snappage that don't really help building confidence... :( Quote Link to comment Share on other sites More sharing options...

Plain crack through the entire tube. (Y) Quote Link to comment Share on other sites More sharing options...
