That's a sweet bike and the only example I've seen in "Bronze", as Lotus describes it. It's probably an 83-84 model according to the Lotus specification sheet. That model Eclair (pronounced AY-klair) was discontinued sometime in the mid 80's and returned in 1987.

We think the original racks were made by Vetta, pumps were Primus and the water bottle and cages were OKG, for the most part. The OKG cage with the plastic base is past it's prime, put it on the collector shelf. I think it's cool how "loaded" that bike came from the factory and how much brazed on equipment it had for the time.

Someone added the extension levers as they weren't standard on that model. Does it have Gyromaster hubs?

While most of the 1983 era upper-end Lotus bikes were using Columbus tubing, the ever popular Excelle, Unique and Eclair all used Mangaloy 2001. The Classique was the only bike in 1983 to continue using Tange Champion. Lotus was getting up to speed by 1983 and I feel the mid 1980's were their best bikes all-around.
