Getting my stem straight

[BigonaBianchi]

I can get my stem pretty much in line with my front wheel just by holding th ewheel between my knees and sighting along it...but is there a more accurate way to get it bang on straight?

Is that not good enough ? I'm sure there's a more accurate way but thats all I've ever done

get a young person to line it up for you

You could use a lazer to project a line along the top tube from the centre line of the saddle through the centre of the steerer cap bolt and line up the stem with that, but why bother ......... ?

Close one eye, line bars up with hub, then check with other eye.

No matter how careful I've been lining the stem up in the garage I can gaurantee that 100 yards down the road I'll have to stop and adjust it, it will always be a couple of mm out.

Which brings me onto one of my pet subjects, why can't manufacturers put a small mark on the steerer and a corresponding one on the stem so you can line them up without any problem?

Ditto frame and seatpost.

I have young eyes but mine never feels quite right. Just try and ignore it.

*Of course you must also make sure that the front wheel is perfectly in line with the top tube.
You might also tape a straight edge to the stem projecting forward over the front wheel, and use that to line up the stem with the wheel.

piece of straight wood, place across the fork, then place a set square on the wood and align with the stem.
