Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Stem trouble

I went to transfer over the stem from my leader to my steamroller. i put the stem on and tightend down the stemcap screw, thats as far as i got before i realized my bars wont fit because the clamp size is different on this stem. So i tryed unscrewing the stem cap bolt and it just keeps spinning i think i might have stripped but it but i didnt even put it tight, how would i go about removing it?

star nut slipping? Just whack at the stem gently and see if you can pop it lose? Worth a try.

No need to wreck your stem. Try drilling out the bolt in the topcap. Even if you have to trash the bolt and cap you can likely replace them at little/no cost at a friendly LBS. If your star nut is stripped you can push it further down into the steerer and replace it with a new one.

All this assuming a threadless setup, of course. Let us know how it works out.

Edit: Just watched your video. Try loosening the stem so that it's easily moved. Then, as you turn that bolt in the top cap pull up on the stem to put some pressure on the top cap and bolt. You may be able to get the bolt to engage enough of the starnut thread so that it can be backed out. Otherwise drill away.

Good luck. You should be back on the road soon enough.

If anything, You can drop the wheel, And grab a tool to hold the starnut in place from the bottom assuming you have a hollow steerer, and then get someone to apply pressure on the stem and remove the bolt, If all goes wrong, drill out the bolt and slip the cap off like said above, From there life has carried on.

Flat Head screwdriver to coax out the bolt. With tape, so you don't scratch the cap.

It helps to be wearing under-armour shirt so you get maximum torque from muscles and dexterity for screwdriver place holding.

I paid my sister to drop it off at the shop while I was at work the guy said if im talking to ppl online that're fgss mechanic that there mostly hack and slash mechanics and but doesn't want to affend anyone lol....Or run hack and slash shops i forget what it was exactly. He also said the bolt was stuck on the headset starcap or something and there was really nothing i could have done to get it loose or some bs. He ran my sister threw the steps to fix it but it was a lot so she didn't remember them to tell me.

All the jokes aside, I think I would just use a Dremel cutting disk and cut down the top cap, which will allow you to get leverage on the bolt to pry it out. You can then use a long steel drift to hammer the bad star nut down into the steerer tube, so you can install a new good one. You can buy a new top cap, bolt and star nut combo for about $10.
