niconj Posted February 27, 2014 Report Share Posted February 27, 2014 (edited) I am about to build a wheel with an Echo TR hub (129mm) which I'll be using with snail cams. I was just wondering to how many Nm the bolts will have to be tightened? As I've used the strong Hope Trials hub bolts until now, I'm a little afraid of stripping the threads of the Echo Hub since the bolts are so small in comparison. Also, does anyone know the max spoke tension for an Echo TR 24'' rim? So far I've build my wheels with a max. of 1100N but as the rim has holes in it, it might have to be lower. I dunno. Any suggestions? Thanks, Nico. Edited February 27, 2014 by niconj Quote Link to comment Share on other sites More sharing options...
FamilyBiker Posted February 27, 2014 Report Share Posted February 27, 2014 in my experience the echo tr are pretty beefy compared to other rims.the ones i laced so far took the usual spoke tension without issues. 1 Quote Link to comment Share on other sites More sharing options...

FamilyBiker Posted February 27, 2014 Report Share Posted February 27, 2014 go for like 1000 to 1050N,let the nipples bed in for a ride,then retension it to 1100.that kind of forges the nipple "seats",so you wont loose tension after that procedure anymore if you tension the spokes to 1100 right away theyll dig into the aluminium.

Blake Posted February 27, 2014 Report Share Posted February 27, 2014 Not sure on spike tension but maybe 15nm for axle? Quote Link to comment Share on other sites More sharing options...
FamilyBiker Posted February 27, 2014 Report Share Posted February 27, 2014 (edited) thats not much compared to the hope bolts.i tighten my hope with 35-40Nm. are the echo ones m6? Edited February 27, 2014 by FamilyBiker Quote Link to comment Share on other sites More sharing options...
niconj Posted February 27, 2014 Author Report Share Posted February 27, 2014 (edited) Not sure on spike tension but maybe 15nm for axle? That seems low especially for non serrated washers. thats not much compared to the hope bolts.i tighten my hope with 35-40Nm. are the echo ones m6? And this seems too much. Tarty (on here) wrote sth. about 27Nm. Edited February 27, 2014 by niconj Quote Link to comment Share on other sites More sharing options...
AdamR28 Posted February 27, 2014 Report Share Posted February 27, 2014 Hmmm, hopefully I didn't, haha. That's way too much for an M6 bolt. I would say no more than about 12Nm depending on the grade. Spoke tension, we go to about 900 usually. 1 Quote Link to comment Share on other sites More sharing options...

I would say no more than about 12Nm depending on the grade. Spoke tension, we go to about 900 usually. I was referring to the hope M10 bolts. So you're saying that the Echo Bolts should be tightened at arount 10-12 Nm? 900 is pretty low I'd say. I don't have any experience with trials wheels though. Sun Singletrack and Spank Stiffy for ex. have a max of 1100N (manufacturer information). To contact Hope is next to impossible. Quote Link to comment Share on other sites More sharing options...

Maximum tension isn't the same as good tension, and those rims are different to Echos... Quote Link to comment Share on other sites More sharing options...
niconj Posted February 28, 2014 Author Report Share Posted February 28, 2014 (edited) Alright. I'll go for 900 then. In MTB it's drive side to the max. (for the rim, spokes are always stronger) and none-drive side for centering the wheel, whatever the spoke tension, it'll always be lower than drive side. I meant the Echo hub. I'll go for 11Nm then. And I also meant contacting Hope is impossible. Edited February 28, 2014 by niconj Quote Link to comment Share on other sites More sharing options...
craigjames Posted February 28, 2014 Report Share Posted February 28, 2014 And I also meant contacting Hope is impossible. Have you actually tried? I've never had to wait more than 1 working day for an email back from Hope, excellent customer service from them. 1 Quote Link to comment Share on other sites More sharing options...
niconj Posted February 28, 2014 Author Report Share Posted February 28, 2014 I have but made a mistake in writing "HOPE" when I actually meant "Echo". Tried to contact them but never got an answer. Quote Link to comment Share on other sites More sharing options...
craigjames Posted February 28, 2014 Report Share Posted February 28, 2014 Not really surprised by you not getting a reply from Echo, that's assuming that they'd have the information to give you anyway! Quote Link to comment Share on other sites More sharing options...
niconj Posted February 28, 2014 Author Report Share Posted February 28, 2014 Not really surprised by you not getting a reply from Echo, that's assuming that they'd have the information to give you anyway! Well, normally you do have a max. spoke tension. These rims get tested before they sell them. Quote Link to comment Share on other sites More sharing options...

craigjames Posted February 28, 2014 Report Share Posted February 28, 2014 If half the stuff that trials manufacturers produced got tested properly before sale, then you'd never see them. Echo aren't exactly renowned for using any type of R&D or product testing. FEA, but that's about as far as it goes. Quote Link to comment Share on other sites More sharing options...
niconj Posted February 28, 2014 Author Report Share Posted February 28, 2014 How can they sell that stuff then? Is this an "only in America" thing? In Germany w/o testing things, you wouldn't even sell some toast. Quote Link to comment Share on other sites More sharing options...

Small companies, with low order numbers, getting items produced by factories in Asia; a lot of it coming out of catalogues. Quote Link to comment Share on other sites More sharing options...
niconj Posted February 28, 2014 Author Report Share Posted February 28, 2014 Well Echo are Chinese, America are no different to Germany or the rest of Europe Doesn't matter where you produce, as long as it's tested properly and this is the crux; in Germany at least there has to be some testing done, if not, you won't be allowed to sell anything.

niconj Posted February 28, 2014 Author Report Share Posted February 28, 2014 Just build the wheel. I have never had such a true rim. All and I mean ALL! the spokes have the exact same tension and the wheel is true. Wow! Quote Link to comment Share on other sites More sharing options...
