At local tri this weekend, someone rode by me on a bike that had a solid frame save for rear triangle. This is a crude drawing but you might get the idea. It looked old, anyone have an idea what it was?
A Trimble? But I thought they had a filled-in rear triangle as well…
No, Brider is right, I remember seeing that Trimble name on it. I thought it said Nimble at first but Trimble is right.
Best bike I ever had.

The only bikes I know of that ever compared favorably with the Hooker aerodynamically were the Softrides, the old Zipps, and the Lotus. The Cervelos and Softrides today probably come closest, and may exceed the Hooker in certain respects, especially in variable winds (this is John Cobb’s opinion). There was one bike that was only very sporadically produced that actually “beat” a Hooker in the wind tunnel, and that was the monocoque made by Brent Trimble. This bike was of carbon and had an entirely solid main triangle, like a disc wheel.

Definately not a bike for Kona…kj

A guy around these parts rides one on our Tuesday TT series. Its a pretty cool bike except in a cross wind!!
Yup. That’s one OLD bike! And because of the configuration of the frame (the pump was INSIDE the monocoque), the behind-the-seat bottle holder was necessary – Trimble was the first behind-the-seat bottle launcher! I’ve still got one of those. Haven’t used it in years – ever since I started riding Softride (won’t work with the beam).
one of the heads of a local coaching service here in Hawaii has a trimble. we’ve been pimping it out lately, it’s bright red with huge decals on it, he’s got a Zipp 909 wheelset now with custom decals, an Oval aero fork and he’s so stretched out on it it kills his back. It’s pretty funny but it sure does get noticed.
Best part is one of the local bike shops had it for sale used for years, frame only. We have this bike swap meet twice a year and every time I went the owner would try to talk me, or anyone else, into buying it. Then last year my friend calls me up after the swap meet all excited, “Guess what I just bought!” I guessed before he could finish, guessed and groaned;)
I have posted about this before…
What’s to keep someone, like me, from fabricating a solid frame using a cover material? Similar to a home made disc cover - simply use mylar or heat shrink plastic on the main fram and part of the right side rear triangle and all of left side rear triangle(?).
(My answer - I would lfeel very silly riding such a frame unless I was able to push over 25mph for a 40k.)

Hmmm. how did you guys modify the headset to get a threadless one to fit?
I guess he would be quit stretched out on it. It had a long top tube and the seat tube angle was 72 degrees.
I liked the disc wheel rumble it made even when you weren’t using the disc.
Great bike we have to get Brent to start making them again.
That would be considered a fairing, something added to the bike for the express purpose of reducing drag, and not serving any structural purpose. With the Trimble, the “fairing” IS the frame. Now with wheel covers, though they are added for drag reduction, since they approximate a disc wheel (which is commercially available), they are waived from the fairing rule.
