question about rule #45

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

question about rule #45

SLAM YOUR STEM DOWN.

They mention A maximum stack height of 2cm is allowed below the stem and a single 5mm spacer must always be stacked above.

When they mention the 5mm spacer stacked above, do they mean stacked above the 2cm below the stem or 5mm spacer on top of the stem?

On top of the stem.

A lot of people believe believe the spacer on top of the stem (and under the cap) will relieve pressure on the steerer tube.

Others disagree.

I've seen different rules for the spacer above the stem - IIRC the manual that came with my bike specifically said not to put any spacers above, whereas at least some Specialized frames/headsets specifically require a spacer above the stem.

Naah - IMHO there's no technical reason for rule 45, it's just a cool-factor. According to the book-of-coolness, bad-assed bikes have flipped stems with spacers above. Whimps and old guys don't.





(Don't look at my bike - and don't you call me a whimp or an old guy! )

I don't think you really have to take "The Rules" literally... I believe they are more of a tongue-in-cheek guidelines on looking cool. BUT, having a 5mm above the stem (on carbon steerers) can't hurt anything.

What you really should be asking regarding rule #45:

I put a spacer above. It makes sense to me, just thinking about the forces involved, that you would want to keep some steering tube above the stem.

Especially with carbon steerers.

A single 5 mm spacer above was my mechanics minimum recommendation due to the varying stack height of stems.

Be an adult. You bought the stuff and can use it or abuse it however you want.

But once you do get your stem set up in a way that you like if there is some steerer left above using a small spacer in lieu of cutting the steerer will leave some flexibility if you ever sell the bike or decide to change it for yourself.

The mechanics at my LBS say spacers above the stem aren't necessary. Which is good, because a 90 mm stem doesn't give me quite enough room to mount the Garmin on, if I have a column rising up from the rear.

A few of them are good rules, but there should be a rule to not take all of the rules seriously.
