1984 Eddy Merckx pista SL 56cm

56cm (st) x 56.5cm (tt). Pearl white. Columbus SL tubing. Rare sloped fork crown. Something I think is typical on a Merckx pista, this bike has a lower bottom bracket height and slightly relaxed geometry, esp the seat tube angle which puts the rider more “behind” the pedals than over them. I’m guessing it’s 74deg head tube/72 seat tube). Bike’s cosmetic condition is a B+ but the bb was shot (and seized) and the headset may need to be replaced. I don’t think the bb had ever been pulled. Light, smooth and good power transfer. Nice lugs. Great paint.

This type of BB cover was used in EMC between 1984 and 1987 in Professional, Pro, Corsa Extra, Criterium and Corsa models; in Pista a bit longer...
If your frame is Z and 3 digits, the frame is from 1984
Yes, "riflings" inside these tubes mean SLX/SPX - with a bit of luck you will see them (a good flashlight is essential!) at the bottom of the seat tube...

EMC started using the SLX/SPX in 1984 - that doesn't mean that since that year the construction of frames with SL/SP has stopped... The Pista SL model was certainly built until the end of the 1980s (EMC catalogues 89,90,91).
"Crimped chainstays" did not mean Columbus SL - they were mostly used simultaneously with the "old" BB cover requiring "chainbridge support"; when new BB cover designs were introduced (without chainbridge - and used with SLX/SPX and SL/SP) "crimped chainstays" gradually disappeared
Nothing in the frame clearly defines the tube model
And just look at the ends of the tubes visible through the BB cover...it will explain the situation

Thank you for the informative explanation. This is why I appreciate Pedalroom. So, I would be looking for the internal helical reinforcements inside the downtube, seat tube and chainstays to indicate if it is SLX? I know SL tubesets did not have this reinforcement innovation. Also, are you saying the SLX bottom bracket shell does not use a bridge?

Why do you think it's SLX? What element distinguishes it from SL? What are the factory markings? The beautiful EM Pista...

That’s a really awesome question. The frame had the original Columbus tubing decal but it was illegible by the time I got it. Prior owner said it was SLX, which I believe, mostly based on cross-research and assumptions based on the tubesets Merckx was using on other models. Other Merckx pista and road frames dated around 1985 used SLX (Pista Mercato has an identical Merckx pista using SLX). SLX was introduced in the early 1980’s and Merckx would have had immediate access to it through his relationship with Columbus. This is a great reference database I use a lot:

Also, SL frames often used crimped chainstays, but SLX does not.
