Trek Y foil 66D?(4 posts)

I've been mountain biking for a few years, but I'm looking to do some more road riding. I've tooled around on some better bikes enough to know a good road bike makes a huge difference, but my budget is around $800, and it will be a few months until I can even come up with that, so I have not been looking too hard.

Then today, a woman I ride with said she had a very nice bike she picked up for a killer price last year, but it was too big for her. It is a Trek Y Foil 66. I think it is a 66D because it has a double chain ring. I think it is a `99, but I thought I read somewhere that the `99 had a threadless steer tube and this has a threaded. Is this correct? It has all Ultegra stuff on it, and has about 1,200 miles on it. She is letting me ride it to see if the fit is right. It is a 54, and I am 5'10" with a 30" inseam (pants, that is). If it fits I think I can get it for about $1,000, and she will work with me on payments.

It seems like a pretty sweet bike (sure looks crazy) but I'm really not familiar with road bikes. Is this a good bike? Why don't they make it anymore? Also, what is the difference between a Race bike and a Triathelon bike? The description in the review section said this bike was for both. Any comments on this would be appreciated.

I have the same bike, except with Dura Ace. The Y-Foil did not offer a threadless version. While the looks are unique, at least for a road bike, the frame angles are similar to a standard road design. Typically, a tri-bike would have a somewhat steeper seat angle to place the rider in a more forward position for aero bar usage.

In terms of sizing, the 54cm model will have the following measurements:

- 54.5cm Top Tube
- 41.0cm Chainstay
- 73.0 Head angle
- 73.5 Seat angle
- 97.9cm Wheelbase
- 29.3" standover

The first time you ride it, you'll probably notice some vertical flex with the frame design. However, within a few miles, you won't notice anymore. It's kind of like using Speedplay pedals for the first time where your feet laterally rotate all over the place. After a few miles, you find a comfortable position and your feet pretty much stay positioned.

For $1000, it's a decent price as I've seen that price being asked for the Ultegra version. I've also seen it for less but I don't know about the specifics on those particular postings.

Good luck.

You can read more about y-foils here:

It will explain why they were discontinued, and give you a sense of what brand-new leftover stock sold for.

Boomerang bikes, a new unbuilt blue 56? was at the LBS for $600 this past spring. Some can be noisy, sort of a hollow hum, or snapping sound when hitting rough pavement although that could be cable housings rattling against the frame. I had the hots for one earlier this year but decided I did not need another bike
