Richard, remember if you have an A-headset, you have to adjust it with the cap and bolt on top.

This is how i replace my stem;

1: Remove the old stem and bar, both allen keys on the stem and topcap have to be undone

2: Fit the new bar and stem together, try to fit the controls later (if possible)
Tighten the bolt for the bar well but with care, especially when the parts are alu, build up tension slow.

3: Fit the stem to the stearer, first you tighten the top cap and check the headset; the barings have to be without space but not to tight
Your front wheel has to turn with less resistance, if you`re not sure about the adjustment, ask someone to feel the steering!

4: Tighten the two bolts on the stem just like the bar bolt.

5: finished!

Two notes; i find it easier to do this with the bike on the ground, because some forks may fall out of the frame tube if the topcap is released, this is nice if you have to clean the barings, but not with stem replacement

Don`t use to much coppergrease, because it will effect the bar/ stem link.

Take the time and patience, Rome wasn`t build in a day either :thumbup:
