Can handlebar for ccm vandal xc 26" bicylce be raised? It seems as if stem is confined by top and bottom bearings. Doesn't make sense that seat can be raised but not handlebars.

The threadless stem style you have pre-supposes you chose the right height and reach when you bought the bike. As the steerer tube to which it clamps has to be below flush with the top surface to accomodate the top adjustment cap, the steerer had to be cut to a final length that can't be made longer. The stem CAN be flipped upside down to provide a different rise and reach, but most likely it would be lower and farther away.

One option is to replace the stem with one with an angle and length that would work for you. Have a bicycle shop asist you in choosing one as there are 4 parameters that must be considered.

Another is to get a threadless stem riser which effectively makes the steerer tube taller. Google "threadless stem riser".

Here's one on eBay...

Can you tell me who makes a threadless stem 25.4mm x130mm to suit a track bike?

Not exactly sure what distinguishes track-bike suitability from normal bike suitability?

Thomson, Profile, Ritchey, Easton, TTT....

A little Google search for "threadless stem 25.4mm x130mm" brings up a zillion stems.

How do I ad a spacer to extend the neck heighth on my Trek 7.6

Modern bicycle stems use the threadless headset system that is usually modified for proper fit (height & reach) once using a stem of suitable reach, angle and length and then tweaking it with spacers. The length of the steerer tube on which they mount can be shortened and cut to size but it can't be lengthened.

A new stem with a higher 'rise' might work for you.

How to fit a odyssey g3 gyro set

Hi MonkeyManTim

Firstly, remove the centre lock nut on the stem. This loosens the stem/headset. Pull the handlebars up and rest them next to the front wheel, make sure the brake cables aren't being stretched too much.

You'll see there is a locknut on the headset (at the top of the frame/top tube where you pulled the stem from) and loosen this (might need a massive spanner!).

Pull offthe toppart of the headset, ball races and lower part. Replace with the gyro bottom and top parts. Grease the ball bearing if they aren't already!

Slide it together, fit the stem and you'll notice the brake lines that come with it. Undo the rear brake, run the splitter cable from the front lever to the top half of the gyro, same with the bottom half. I found putting some padded stickytape on the bars helped here as the splitter cable would 'ting' off the bars.

Undo the front brake and run it through the stem hole, through the forks and cable tie it to one fork leg.

Test the brakes, adjust where necessary and on you go pulling bar-spins for fun. Please don't land a jump with the bars half spun, it hurts....a lot!!

Hi i have a futaba gy401 gyro with a s9254 tail servo, i had a crash and since then my tail servo constantly wags from left to right every time i switch on heli, i have tried putting the gyro on another...

If you put the gyro on another helicopter and have the same problem then you'll need to replace it. I've tried repairing these in my lab but just not worth the effort. Good luck

I can't fit back together my gyro brake system on my gt fly 2007. is there an instruction manual available please?

Try this link. I'm putting mine back together after stripping and repainting the frame. I consider myself mechanically inclined but this is a confusing set up! My problem is that the kid I bought the bike from had it set up incorrectly?? I hope. because from what I can tell, the bottom plate should directly contact the frame, thus i need to remove the headset, install the bottom plate (which says odyssey gyro) and then tap the headset back into place. from there, install top bearings and refer to the picture in the link. I'm doing some research to figgure out what the hell I am doing wrong, and why cant I figgure this thing out!! I think I have it, gonna try again tonight. SO if any of you ppl who have actually installed these things correctly notices that this is incorrect, please inform us! Hope this helps!
