Bridgestone was making highly regarded bikes, mass produced or not. Example, a state-of-the-art rig would be a Ritchey P-23 (c. ~1990), so named because it was a project to make a 23lb bike, which was a Big Enough Deal to name the bike after the project. I feel like the bikes[0] I[1] raced[2] at the time ($1800 - $2600, not adjusted) were in the 25-26lb range (19.5 - 20.5&quot; frames). The very light bikes (like a P-23) were contraindicated for heavy, non-expert riding. Working at a high-end bike shop around that time, I saw them[3] come back in pieces.<p>[0] <a href="http:&#x2F;&#x2F;www.retrobike.co.uk&#x2F;forum&#x2F;download&#x2F;file.php?id=35724" rel="nofollow">http:&#x2F;&#x2F;www.retrobike.co.uk&#x2F;forum&#x2F;download&#x2F;file.php?id=35724</a><p>[1] <a href="http:&#x2F;&#x2F;www.retrobike.co.uk&#x2F;forum&#x2F;download&#x2F;file.php?id=258229" rel="nofollow">http:&#x2F;&#x2F;www.retrobike.co.uk&#x2F;forum&#x2F;download&#x2F;file.php?id=258229</a><p>[2] <a href="http:&#x2F;&#x2F;i41.tinypic.com&#x2F;j9y5ug.jpg" rel="nofollow">http:&#x2F;&#x2F;i41.tinypic.com&#x2F;j9y5ug.jpg</a><p>[3] <a href="http:&#x2F;&#x2F;fcdn.mtbr.com&#x2F;attachments&#x2F;vintage-retro-classic&#x2F;125402d1134938352-first-gen-rocky-mountain-wedge-89wedge.jpg" rel="nofollow">http:&#x2F;&#x2F;fcdn.mtbr.com&#x2F;attachments&#x2F;vintage-retro-classic&#x2F;12540...</a>
