forteh Posted September 8, 2009 Report Share Posted September 8, 2009 (edited) it is a pro2...but i said i want a king lockring on it as i already have one lol King threads are quite likely to be imperial where as the hope is almost guaranteed to be metric. When you say you have a king lockring I presume you mean one of these?It might well be worth sending an email over to chris king in the states to ask what thread it is, if you state that you want to use it in another application then they might tell you, Ive found them to be very helpfull Edited September 8, 2009 by forteh Quote Link to comment Share on other sites More sharing options...
Muel Posted September 8, 2009 Report Share Posted September 8, 2009 Just to clarify...there is no room to have a thread put on the inside as the bearing is there, the bearing cant be moved else there will be too much stress on the freehub body and nothing to stop it pulling when putting pressure on it...faceplant jobby!It has to be cut onto the outside.Looks like im gonna have to get a lockring made with some threads in. Will the fact that king is american? affect the thread size?that may be a stupid question lol.There is? Just get the bearing race moved 5mm further down the inside of the hub, that'll give you space for a proper lockring and you still keep all the bearings.Just get the race machined out when you get the thread cut into it.

Try phoning King they might be able to help, failing that a machine shop will be able to tell you what thread you need and then use a die to cut the outside of the hub shell.

forteh Posted September 8, 2009 Report Share Posted September 8, 2009 Think jardo probably means UNF @matt, its not a standard pipe thread, if anything it will be BSC (same thread form as screw on sprockets/threaded axles/BB shells).

What you have quoted is AF Spanner sizes where AF is also used to abbreviate Across Flats as a measure of the spanner. I know, I've got hundreds of AF spanners...Don't you boys know anything about the old school ? Edited September 8, 2009 by Pashley26 Quote Link to comment Share on other sites More sharing options...
PaRtZ Posted September 8, 2009 Report Share Posted September 8, 2009 great two letters, who cares that much.This is seeming like a lot more work than originally I thought. It started out about asking about the thread being cut, but now its involving bearings moving and pushing and other stuff I probably didnt read....A profile hub is pretty damn good + cheap for mod you know? Not meaning to be cocky but, are you sure its worth it? I know its the feel good factor of having it on your bike like, but still might cost loads more Quote Link to comment Share on other sites More sharing options...

What you have quoted is AF Spanner sizes where AF is also used to abbreviate Across Flats as a measure of the spanner. I know, I've got hundreds of AF spanners...Don't you boys know anything about the old school ?AF is the spanner size."American fine" thread is UNF GE gas turbines are full of UNC and UNF threads so, yes, I am familiar with the old school- I looked into doing this recently but gave up not because it was too difficult but because it isn't worth the hassle.I cant remember the actual measurements but the best way I could come up with was as follows:-Get hold of a Pro 2 trials hubSell the hub shell, axle, bolts.Get hold of a pro 2 cassette hubshell and axle.Put the Trials drive shell on the pro2 cassette hub without the QR end bits in place.You now have exactly 116mm across from one side of the hubshell to the other side of the drive shell and obviously too much axle.Machine 6-8mm off the hubshell on the disc side.Machine the bearing recess 6-8mm deeper.You now have a 110mm hub with too much axle.Now here is the bit that I got stuck on.I would guess you need a bolt through axle to go through the quick release hollow axle both machined to length and some snail cams/spacers on there to preload the bearing so you would have to machine a bit off the ends of the hollow axle so you have a total axle length of about 115mm so the cams/spacers press against the drop outs.Chuck it in the bin and:A: Buy a Chris King BMX hubB: Buy A screw on hub and a tensile 96 click freewheelC: Winge at hope because they are really missing a trick not making BMX hubs both in the trials market and the ever growing BMX market, ferf**ksake shimano are making BMX shit now what are hope thinking/not thinking.Or something like that.My main point is that with a pro2 cassette hubshell you can loose alot of width without too much machining or any machining of the drive shell You would have alot of dish in the wheel though Matt Edited September 8, 2009 by Matt Vandart Quote Link to comment Share on other sites More sharing options...
jambo Posted September 8, 2009 Report Share Posted September 8, 2009 Well after having a read at what everyone's chat was on this thread i decided to email hope bumming how good the pro 2 is kidded on i rode a mod and asked if it was possible for them to modify the hub to fit a 116mm spacing. This is the reply i got.Hello james,there is no way modifying your current hub but we are working on a model of hub to suit what you require but have no idea when it will be available so hopefully sometime will be able to get it onto the market. many thanksnick Let the waiting commence but if your 10 years old i think you may well have a beard buy the time you get a chance to buy one.

Revolver Posted September 8, 2009 Report Share Posted September 8, 2009 I really don't think a 116 proIIt would be hard to make, from the angle of making it from scratch. Modifying... well, AFAIK there's only two knocking around. Although there may be a 3rd one that's a genuine hope prototype. Quote Link to comment Share on other sites More sharing options...
