Re: gt stem help (pics)

You would need a hollow bolt to rout your cable down it.  Keep in mind it will be wider than your existing bolt and you would have to drill out that washer for it to fit.  Also, your wedge bolt will have to fit similar to the existing one as well.

K.   I saw a pot t mod bolt on porkchop.  I wasnt sure if they made a washer designed for it or not.  But drilling it seems pretty easy.

Re: gt stem help (pics)

Yea, you just need to make sure the wedge bolt is like the one on your existing non hollow bolt.  I just put one on an old stem I had.  I had to drill the hole out a bit and luckily the wedge bolt on the pot's mod was the same.

Re: gt stem help (pics)

This same stem was used for freestyle and Race bikes. It is a 88-89 stem. The missing cap was just for looks and its made of plastic. It clips into that washer and they got lost all of the time. If you want to use it for freestyle you just need to get a potts mod blot for it and runs a Gyro... Or you can drill out that dimple on the top to run a cable through if you want to run an ACS style (UFO) rotor. If you do drill the hole out you will just need to make sure you can put a brake anchor or threaded brake hangar in that hole to hold the brake cable itself.

Re: gt stem help (pics)

Man,I hope that bolt and wedge work for you. The wedge has to fit the stem quil right or it won't grip well. I bought one from Porkchop and it didn't go with my Haro group 1 stem at all so I had to run it on a generic stem I had. Once I got it all set up on my rider after only a few stunt runs the whole stem twisted sideways because the wedge wasn't gripping.

The whole stem and wedge thing has to be just right or it won't work unless your not doing freestyle.

Hope it works out for you

I would order a stem bolt and wedge that come together. They have to be compatible with eachother. Threading and bolt diameters can all be different. Last time I checked Porkchop was out of the one you would need.

Once you get the bolt and wedge as I stated up top the wedge has to be compatible with the stem quil.The cut angle on the bottom. If your wedge isn't compatible with the stem quil and you absolutely have to keep that stem then take it to a machine shop and have them cut and adjust your stem to match the wedge and bolt. I have a machine shop down the road from me and one at my work and it's amazing what they've been able to do for me. They only charged me $10 to re knurl and pop a Haro Group 1 stem back together when it came lose once. Then I had them do all the others I had that came lose.

It may be easier for you to just get another stem thats designed for freestyle with the original Potts Mod bolt and all other hardware. I have found that racing stems sometimes have the smaller bolts than the freestyle stems. It also may hold up better.

Sorry for taking up so much of your thread. Good luck.

Re: gt stem help (pics)

BTW. I had an old basic stem once that didn't have the Potts Mod bolt like yours. I bought the bolt and wedge from Porkchop. The hole in the stem was too small fort the bolt so I took it to a machine shop and they made short work in drilling a bigger hole and setting it up for me just right. I brought it home and installed it in my 87 Master and did a few short stunt runs and my bars twisted sideways everytime I jerked the handlebars around. Junk.

I also had my machine shop at work drill a hole through a basic stem bolt that didn't have the hole cut out and they made it Potts Mod compatible for me. You could try that on the bolt you already have also. Then you dont have to buy another bolt. Either way make a friend at a machine shop.

Re: gt stem help (pics)

If you don't mind it being black, there's one on eBay right now. Item # 181028228293

I bought one of those bolts from Porkchop and the wedge cracked when I went to tighten it, so be careful if you end up going that route.

There's also a really nice black Tuf Neck with a potts mod bolt on eBay right now. It reminds me of the stem I have on my Redline. I only had to do a little filing to get this bolt to fit into my Pro Neck. No drilling needed.

http://i87.photobucket.com/albums/k124/lillare/BMX/86_rl-20_ps/121102_0051.jpg

Neither of those items are mine, so don't think I'm here to sell you something. Just trying to help you out. However, I do have that Porkchop bolt and spare wedges if you get desperate. wink lol
