MadNick1.2 Posted July 19, 2009 Report Share Posted July 19, 2009 (edited) Hi All,I have a problem!!I have bought these from a friend for £50.http://www.tartybikes.co.uk/product.php?pr...;category_id=40Please take a look.As you can see, a bargain i though, now here is the annoying problem.The steerer tube is cut to fit my friends frame and is 15mm too short when on mine. This means the top of the forks is 15mm too far away for the top cap to screw in.Their are a few ideas which i have come up with to solve this:1. Buy a new stem with a clamp size of around 35 - 40mm (the one at the moment is 55mm and around a 19 degree rise and 90mm long).2. Buy a new internal headset in an effort to save 15mm of fork tubing, means getting rid of the old standard chris king.Has anyone got any other ideas and would it be possible to save 15mm in the stack heights of a standard headset to an internal one.Please help!!!!

Ciguena_dreamer Posted July 19, 2009 Report Share Posted July 19, 2009 My forks are like this, I'm running a star nut instead. If you can, try and wack a star nut in there and run a longer Top cap bolt. I've been running mine for about 2 weeks now and it's been fine Quote Link to comment Share on other sites More sharing options...
Muel Posted July 19, 2009 Report Share Posted July 19, 2009 I have this exact problem with a set I am currently trying to buy.I am going to make an adapter that screws into the fork using the thread designed for the top cap thing, and has an M5 thread so you can use a normal topcap and bolt.If I can get it made, I will see if I have enough material to make two, and if I can I could make one for you aswell?If not I'll send you the design and you could get someone like Edd Potts to make it for you. It may be a week or two before I get it sorted out though I'm afraid, will keep you posted though. Quote Link to comment Share on other sites More sharing options...
N.Wood Posted July 19, 2009 Report Share Posted July 19, 2009 I made a ghetto star nut thang when I wanted to use a Try-All sloping stem on my trialtechs. I cut the 'mushroom' top off the screw in bolt, found an M5 nut with a small ridge around the bottom on Porter's dashboard, screwed the threaded bit into my forks with the nut on the bottom, put in a normal top cap and bolt and there we are.All info courtesy of Mr. Tarty Adam.

Ciguena_dreamer Posted July 19, 2009 Report Share Posted July 19, 2009 You won't get a internal headset in, only some frames are made for internal headsets. Quote Link to comment Share on other sites More sharing options...
MadNick1.2 Posted July 19, 2009 Author Report Share Posted July 19, 2009 Only other option is a new stem.Need one around 100mm long, 20degree and 35-40mm steerer clamp.Any suggestions?? Quote Link to comment Share on other sites More sharing options...

Revolver Posted July 20, 2009 Report Share Posted July 20, 2009 Basically, picture a steerer tube with a huuuuge bolt in it, that goes through your top cap, and a nut that you can tighten, which presses on the outside of the forks - thus pulling the topcap- and everything underneath it - into the forks.You know what, f**k picturing it, look at this: Quote Link to comment Share on other sites More sharing options...
Mark W Posted July 20, 2009 Report Share Posted July 20, 2009 I'd be more concerned with having my steerer being dangerously low in my stem's clamp. Ideally it shouldn't go below the half-way line of the top-bolt of your stem, let alone being over 15mm away from the top of your stem! Asking for trouble, especially with the use they get when you ride trials... Quote Link to comment Share on other sites More sharing options...
jim-p Posted July 20, 2009 Report Share Posted July 20, 2009 (edited) I was browsing on Tarty for a solution to this and i found quite a cheap solution in a form of a new stem:First stemThis stem only offers one length (120mm) with 6 Degree riseSecond StemOn the other hand this stem offers a variety of Lengths that you can pick from best to suit you style and the geometry of you bike, but again only 6 degree rise only : /Third StemIf your willing to 'splash the cash' a bit then heres another option, the shorter version of the echo SL stem has pretty much the same rise (18 degrees) as what you have on your current stem; but is also 40mm longer than your current stem. The steerer stack height on this stem for the shorter version is 38mm, so this abolishes your problem Overall all of these stems offer what you need the most; 35 - 40mm steerer stack height. This solves your problem in short, lol. Although some maybe rather more expensive than others Hope i have helped mate Jamie Edited July 20, 2009 by jim-p Quote Link to comment Share on other sites More sharing options...
Muel Posted July 20, 2009 Report Share Posted July 20, 2009 Designing my adapter thing up now, just let me know if you want one making and I'll see if I've got enough spare material. Quote Link to comment Share on other sites More sharing options...
MadNick1.2 Posted July 20, 2009 Author Report Share Posted July 20, 2009 Sorted i think!!I emailed Tarty last night about a stem which i liked the look of on thier site.A TrialTech one by coincidencehttp://www.tartybikes.co.uk/product.php?pr...;category_id=41As your can see from the spec this has no info on the clamp stack height.This is why i emailed them and an amazing stroke of look it is 40mm. Now i can have a matching stem for my forks, althought 30mm longer and 2degree less rise.Thanks to all the ideas i got thier in the end..Thanks again Quote Link to comment Share on other sites More sharing options...

ogre Posted July 20, 2009 Report Share Posted July 20, 2009 i ran forks with to short a steerer, it made my stem snap at the clamp Quote Link to comment Share on other sites More sharing options...
durkie Posted July 21, 2009 Report Share Posted July 21, 2009 I dont mind buying a new headset as the chris king is neary dead.seriously? isn't the whole point of buying a chris king cause it has a freaking 10 year warranty on it? Quote Link to comment Share on other sites More sharing options...
MadNick1.2 Posted July 22, 2009 Author Report Share Posted July 22, 2009 The chris king headset come with the bike and i dont think they will carry the warrenty over to the new owner.They would probably want proof of purchase or somethin.Anyway got my new TrialTedch forged stem now and have put it on and it fits perfect.Looks pretty good now as well.Although i come to adjust the stem today becuase i did the top cap up too tight to try and stop my king headset from rocking and the stupid "special" top cap they come with has rounded off Have emailed Tarty and TrialTech to see if i can get a replcement.Feels loads lighter on the front which is always nice!!

Comedy bails every time, just end up sitting there with your bars in your hands. Quote Link to comment Share on other sites More sharing options...

Tom Booth Posted July 24, 2009 Report Share Posted July 24, 2009 Muel, just fit the topcap type thing, grind flush with the forks then finish it smooth, drill it, helicoil? Quote Link to comment Share on other sites More sharing options...
JonMack Posted July 24, 2009 Report Share Posted July 24, 2009 Unfortunately the hole is pretty big, but Muels adapter would sell pretty well I reckon. Quote Link to comment Share on other sites More sharing options...
MadNick1.2 Posted July 24, 2009 Author Report Share Posted July 24, 2009 Tarty bikes sell a replacement top cap for these forks. £8 incl postage. So will probably get one soon. Will get the old one off somehow.Did the top cap up tightish to stop the headset from moving back and forth and it seems to have bedded down now so hopefully won't need a new headset.
