I'm trying to help the local co-op price a frame that came in as a donation. It's a quite large time trial frame with a Reynolds 853 decal. Tubing is aero-shaped rather than perfectly round. Decals suggest it might have been made by Advanced Training Products in Oregon (Hanz and Alan Scholtz now of Bike Friday). I've contacted them to see if they did make it. It takes an unusual 30 mm OD press fit BB bearing similar to Merlins and Litespeeds of the 90's, which may or may not be a clue. It also has a pretty unusual seatstay/chainstay design. Also seems to be designed for a downtube shifter for the FD and bar-end for the rear (I'm assuming it had aero TT bars). I don't know if any of that helps clue who might have made it.

So, on the plus side, it's Reynolds 853.
On the minus side, there's that weird BB standard, and it's a pretty aggressive downward sloping top tube TT geometry, so not exactly comfortable for a lazy sunday ride, and I doubt many people are still interested in a steel TT bike for actual racing. It's also quite large - 64 cm to the top of the seat tube, 57 cm to the top tube (the big difference is due to the long seat tube extension)

Any thoughts on a ball-park ask for the frame alone if willing to ship nationally? (I've added a fork and wheels for one photo just to show the geometry, but just the frame is the item of interest. Fork isn't original to the frame.)

For TT bikes of that design, you can ignore the length of the seat tube. For sizing, measure the effective horizontal top tube length. It should be the same as or very close to that of a road bike that fits the rider correctly. If the TT bike is the right size, there should be no more than one or two inches of exposed seatpost.

As shown, the seat tube and head tube angles look very shallow and the there's not much BB drop. Consequently, I believer this is intended for a smaller diameter front wheel and matching fork. The lack of the proper fork would severely impact the value.

The vast majority of sloping tube TT frames that I've seen were intended for bullhorn handlebars. Consequently, the head tube is shortened and you do not you use an effective horizontal top tube for sizing. Most used an aero seat post, so they had a traditional amount of seat post showing and used traditional seat tube lengths for sizing.

Edit: The down and seat tubes are not aero along their entire length and appear round at the ends. This practice was pretty common in the early 1980s, when manufacturers wanted an aero frame but were still using lugs. However, it is atypical for what appears to be a TIG welded frame.

Looks like it needs a fork intended for a 650c front wheel

idk what its worth. but i love it

I am not an expert in this style of bike but I don’t think there is much value there. The only TT “funny bikes” that sell for anything appreciable are the well known names, fully, period-correct equipped. My guess, and this s only a semi-educated guess, is that it will sit for a long time and someone who wants to take on an unusual project will pay $25-50 for it. Maybe try it on eBay for awhile at $100 or $150 in case there’s someone out there looking for that exact frame.

Without the original fork and no historical information, it's a curiosity. That said, I'm interested in it, if you put it up for sale...Best regards, Eric

FWIW, I had an ATP "Red Cross" cx frame and have a Bike Friday. Both have the same one-piece rear triangle design as this frame, so it seems likely that this is indeed from ATP. Someone at BF could probably provide some background.

The ATP reminded me of a Mongoose IBOC from the mid-90's. Same looptail monostay design, though in 7005 alu instead of 853 steel.

Thanks for the input, all.

And an update: Alan Scholz from Bike Friday confirmed that they made the bike in the pre-Bike Friday years when they used the name "Advanced Training Products". It's a rare example of a TT bike from the Scholzes, but I realize that rare doesn't mean any more valuable, except maybe to a big Bike Friday fan.

His recollection is that it took a 700c front wheel, but I agree with the comments that the seat tube angle suggests 650 might be more appropriate.

I'm not so sure that fork was intended for 700c. As pictured there seems hardly enough room for a tire between rim and crown.

As wild guess would put value at $100-150 as is I know higher would be nicer on a great looking pro comp level frame.But finding a nice vintage Kenises allow or nice carbon 650 aero TT fork may be a tough find and may cost as much as the frame.
