Klein Aeolus 57cm TT triathlon frame fork tri 650c cervelo quintana roo zipp

Hi folks,

This item has been relisted on ebay.com as there is no "triathlon" category on ebay.co.uk.

This bike was built up twice, first as a singlespeed. That didn't last long as I gave myself a knee injury riding it around Tenerife.
The second time it was built up as a TT bike as part of our rental fleet. It was only used ONCE in this configuration.
I have decided to sell this bike as it is just sitting there and really needs to be appreciated by another owner, either used on the street or in a proper 'retro' collection.
Note that there is no reserve on this auction.

The frame still looks like new, although wheels have been mounted so paint has flaked off at the rear dropouts (to be expected). No scratches.
I think it's one of the best remaining examples of a Klein Aeolus. It probably has only been ridden a total of 300km in 20 years, and it still looks like it was bought yesterday.
(note the yellow Vittoria tyres were originally installed on my Kestrel 500, that explains the wear discrepancy...)

This frame, or rather the company, deserves an adequate description. The aeolus comes from a time when Klein was at the pinnacle of aluminium frme technology. It uses multi-butted 'gradient' tubing thoughout.
After Trek bought out Klein, you started to see carbon being introduced on various Klein models, some have the view that this would not have happened without Trek invovled, as Mr Gary Klein was a big believer in aluminium. In fact he was the original one to make oversized alumium popular. Before that quality frames were all made of Reynolds 531 chromoly steel. Anyway, I am probably not the only one that thinks of these all-aluminium models are in fact superior to their newer full carbon counterparts. It probably wouldn't have been "the end of an era" if Klein simply had have gone straight to organic full carbon designs. Instead, they opted to introduce carbon on the seat stays, like everyone was doing at the time. The term "cookie cutter stays" come to mind. They were made by someone else and simply glued in place. The sharp junction between aluminum and carbon just didn't look right alongside the totally smooth lines to be found on the rest of the bike (note the totally smooth alloy welds for example).

This particular bike has some of the shortest chain stays ever seen on a bike, 37.4mm. Excellent power transfer!
I have included the full geometry table at the bottom of the listing...

I am including the Alpha Q fork and a 1" token headset in this auction.  The Chris King headset not included, I need that for another bike of mine... ;-)

The Alpha Q fork was also one of the most desirable & lightest forks on the market when full carbon forks became mainstream. This is a 1" model, full carbon steerer. The fork is a recent upgrade as this bike was originally sold with a matching painted steel fork.

I have included many photos, but you are bidding on just the frameset. A frameset consists of three parts: frame, fork and headset.
I'll be selling the blue-spoked spinergy xaero PBO wheelset in another, separate auction.

I have included a tonne of recent photos... note that the frame appears more blue in the last shots, this is because I used a flash in those pictures. The frame is actually more green, but shows up at some angles as blue. It's a two tone paint job, not chameleon paint.

Klein Bicycles really came to the fore in 1993 with its highly regarded (and mass produced), Quantum Pro aluminum frame.
The Quantum Pro had been specifically designed for road racing and boasted an integrated headset fork with threadless aluminum steering shaft for a head-set type stem.

Klein Bicycles led the way in the Cycling industry with many of their innovations.

Bicycle frames became cleaner and less cluttered with the emergence of the Klein Bicycle frame that saw the brake and shifting cables hidden inside the frame tubes.

All of Klein Bicycles frame technology were swiftly adopted by - and revolutionized - the the rest of the bicycle frame manufacturing industry.

In 1995 Klein Bicycles was bought out by the Trek Corporation.

Trek only continued to produce Klein branded bikes until 2005, and it is not clear whether the Klein Bikes name will be resurrected.
