For Sale: Titanium seatpost

...hmm.... well my take is in-line seat posts are only useful for Track bikes for sprinters, where you need to get the saddle over the bottom bracket to spin

I don't possess and never have had an in-line seat post.

The in-line ones I've seen on road bikes have made the riders crap at hill climbing, as there you do need the layback for the power stroke

There is of course a "horses for courses" rule, but relies on a person knowing the ins & outs of where they want to be.

I saw a racing bike on Saturday with layback post plus the Fizik at the end of its range, and reckon the rider would be having probs with the front wheel lifting off the ground there was so much weight so far back.

From my understanding each cyclist has an optimum BB-to-saddle nose distance. This depends on the length of certain bits (I forget which are most critical but it's not your toes).

I've bee told I need to have my saddle nose about 4cm behind the BB which with some bike/saddle combos an inline post is best.
