Having been associated closely with Trek during his racing career, Lance Armstrong has tweeted that he now has a new Parlee Z-Zero road bike.

Lance said, “Down @mellowjohnnys building up my new @parlee_z1. What a beauty!! Right at 15 lbs.”

Mellow Johnny’s is a bike store in Austin, Texas, owned by Armstrong. The name comes from maillot jaune – French for ‘yellow jersey’.

Mellow Johnny's is a Trek dealership. Whereas usually Trek might not be too pleased with an ex-pro and current dealer showing off a bike other than a Trek, in this case they're probably fairly relaxed about the situation.

The Parlee race bike brand was established by Bob Parlee in Massachusetts about a decade ago.

The Z-Zero is custom-made to order in 16 semi-custom sizes, or in a full-custom geometry. Parlee say that they can tune the ride characteristics to each rider's exact requirements.

Armstrong has gone for a Shimano Dura-Ace 9070 groupset here. Previously, he had a contract with SRAM but the US component brand terminated it last year in the light of revelations about Armstrong’s doping during his race career – you might have heard about that!
