and for high tech & well designed, look at Syntace’s carbon P6. it’s won every test it’s been in. weight sub 200g for a road bike.

thanks for a lovely blog.

I won a 3ttt seat post in a race in 1974, two separate bolts, one to tilt, one to secure fore and aft, and light, but almost impossible to find another.

Today, I am a bit puzzled by the stem headset, fork constructions out today. Trek for example suggests 5mm spacing between the headset and the stem to avoid point loading and breakage…One has to get the info from a tech guy here. Hello?

Typical stems are easier to change in length often today, compared to yesteryear where complete “treading” through the bars was required, but where did the common sense go?

I have another cool application for can shims, for protect the chainstay, with your favourite drink out side. Warhol touch for your ride!.

You should place this on one extrem on the groove area to avoid slipping between seatpost and saddle, just a bit is enough, a tighten the bolt a bit more than usual.

Easiest solution is make this with a old can of beer or soda, cutting a small piece. I know is a botched job, but it´s a past-midnight solution-I-want-to-go-to-bed for a beater bike.
