The "L" means long top tube. For a while they were using this in their serial numbers, but it seems like all of them from those years had the "L" in there.

As Keith mentioned, earlier in the decade Serotta offered different top tube lengths on their steel frames. For example the standard geometry 58 cm frame had a 57 cm top tube, the long (58L) had a 58 cm TT, and the extra long (58X) had a 59 cm TT. In 1995 Serotta dropped the optional lengths and the L lengths became standard on 53 to 62 cm stock frames. The stock Ti frames were all built with the L geometry.

The rest of the code follows the modern 'rules' -- the second grouping is the size (59) and the third I assume is the number made (003)

Great bike, a keeper.

I recently acquired CU 59 005. Indeed a great bike for my gravel riding adventures. I did change the brakes from TRP 8.4 mini-v’s to polished Paul MiniMotos. Thought you’d like to see it.
