RiderRace Posted January 20, 2011 Report Share Posted January 20, 2011 Looking to get a chain tensioner for my Echo hub, but I'm not sure how to determine if it's the TR (10mm) or the SL (12mm) version. The outer diameter of the actual axle measures about 15mm, whereas the axle bolt measures 10mm... Any help? Thanks Quote Link to comment Share on other sites More sharing options...
monkeyseemonkeydo Posted January 20, 2011 Report Share Posted January 20, 2011 Does it look like this Or does it look like that ? They're quite different... Or am I missing the question? Quote Link to comment Share on other sites More sharing options...
RiderRace Posted January 20, 2011 Author Report Share Posted January 20, 2011 (edited) It's quite different than both, and it's splined. I have absolutely no idea how old it is... Edited January 20, 2011 by RiderRace Quote Link to comment Share on other sites More sharing options...
Ben John - Hynes Posted January 20, 2011 Report Share Posted January 20, 2011 Neither. It's just a standard echo fixed one from a few years ago Quote Link to comment Share on other sites More sharing options...
monkeyseemonkeydo Posted January 20, 2011 Report Share Posted January 20, 2011 It looks kinda like one of the fixed '07's with the 'integrated' tensioner, after the tensioner's been removed and replaced with a plain spacer. Quote Link to comment Share on other sites More sharing options...

I believe hes right. Quite few riders used to do this if they had horizontal drop outs, as they didn't need the tensioner. Maybe ask the prvious owner if you can see if they still have the tensioner? assuming you purchased it second hand. Quote Link to comment Share on other sites More sharing options...

Failing that I have a spare one in the garage from when I did exactly that. Quote Link to comment Share on other sites More sharing options...

I have absolutely no idea how old it is... 07 as said, you can't fit an integrated tensioner to that hub, sorry! Edit: Well, you could, but Echo don't make one to fit.

RiderRace Posted January 20, 2011 Author Report Share Posted January 20, 2011 Alright, so I've got this particular wheel to which a tensioner can't beattached. It's on a vertical dropout echo pure frame... How would I go about adding a tensioner then? I don't feel like dropping the dough for a new hub, but is that my only option?

N.Wood Posted January 20, 2011 Report Share Posted January 20, 2011 Not sure if a 2 wheeled tensioner will line up with that hub or not? If not, then a 74Kingz style one will work. Quote Link to comment Share on other sites More sharing options...
RiderRace Posted January 20, 2011 Author Report Share Posted January 20, 2011 Are you guys sure this isn't the same as my hub? Looks very similar to me (but I'm new to this as well). Quote Link to comment Share on other sites More sharing options...
monkeyseemonkeydo Posted January 20, 2011 Report Share Posted January 20, 2011 That's what I think it is and it's one of those tensioners I have in the garage. Quote Link to comment Share on other sites More sharing options...
ghostrider88 Posted January 20, 2011 Report Share Posted January 20, 2011 If the hub bolts are hollow,10mm diameter,you have different type of echo hub than the one on the picture and you won´t be able to fit this type of tensioner. Quote Link to comment Share on other sites More sharing options...
RiderRace Posted January 21, 2011 Author Report Share Posted January 21, 2011 (edited) This is where I get all confused with this hub lingo... Let me lay it out straight, as I would really like to buy the tensioner off of this guy if it'll fit my sweet gold hub: The allen head bolts that are used to tighten the hub to the frame are 10mm in diameter and not hollow. The axle itself (that rides on the hub bearings) is 15mm in diameter (and is hollow to accommodate the allen head bolt). In this case the tensioner I need has an ID of 15mm with the key to fit into my vertical dropout, if it exists. Soooo, Monkey, if the tensioner in you garage has an inner diameter of 15mm, I'll buy it off of you (depending on the price of shipping to get that little thing over the pond). (pm me if so, so we don't turn this into a FS thread... ) Edited January 21, 2011 by RiderRace Quote Link to comment Share on other sites More sharing options...

The later ones were like that, but the one RiderRace has is a slightly older version which has a 15mm OD female axle, with 10mm male bolts (like a Pro2). You can fit a tensioner to the derailleur hanger (http://www.tartybikes.co.uk/images/custom/bikes26/large_purebuild5.jpg), something like the Trialtech/Try-All/Tensile will work great.

RiderRace Posted January 21, 2011 Author Report Share Posted January 21, 2011 Adam, :bow: :bow: :bow: :bow: Are you familiar enough with the dimensions of these tensioners that there would be enough material to machine that 12mm hole to a 15mm hole? I was leaning towards the simplicity of a spoke tensioner, as it's much easier on the college budget, but would like to get something a little neater on there.
