Anyone here into old TT tech? Great if you can post pics.

Talk to Quang, he has some amazing older bikes.

This should be the appropriate topic:

Yeah I know about his collection. Seen them in person.

Mostly TT bikes from early 1980s to early 2000s

Time trials originated in England back in 1895, but when did they become specific bikes, different from the road bikes of the era? While I have an early 80s frame made of Tange aero tubing, I don't think it would have been a TT bike, rather than part of the aero fad at the time.

Gitane USA claim to have made the first TT bike in 1981 with aero tubing, backward mounted front brake.

Things certainly got a whole lot more radical in the mid to late 80s.

The first bicycle to designed around those new fangled aero bars (note the 80 degree seat tube) in the late 1980s was the Quintana Roo 'Superform' introduced in 1989.
This example belongs to me.

TT specific bikes were around at least as early as the 60s, though of course they weren't as different from road bikes as they are these days.

Light weight was the main focus then, the usual method being to drill the hell out of everything.

Cheers ld, drillium handlebars ? I'll pass thanks


Obviously took a while for aero to catch on though - I'm not aware of TdF riders using different time trial bikes until the 80s when they started to experiment with bars & disc wheels.

Scott aero bars came out in 86 or 87 so marc's Qunintana roo was an early adopter

1986, Ukrainian 50km ITT championship. Riding the kickass Takhion. No water bottle, of course. 28-spoke Campagnolo hubs laced to Soviet-made 'aero' rims. 100km TTT the next day, and then the road race. These were the days.

Here is my mid 1980s Rossin Cronos TT bicycle. These used a sloping top tube and smaller 650c front wheels. These type of bikes had many names, Profile bikes, Funny bikes, and Low Profile or Lopro bikes. They began making their appearance in TT and Triathlon competition from the early 1980s. This big wheel/small wheel configuration was banned by the UCI in 1996.
Mixed groupset; Shimano 600 ax aero delta brakes, and levers (aero meant internal cabling back then). Campagnolo 180mm cranks and Record 7-speed rear derailleur (friction not indexed; indexing was introduced by Shimano in '85 or so). Front derailleur and pedals are period Dura Ace. Cinelli Domino (extremely rare) stem but will replace this with a period correct high riser MTB stem soon (that's what they did back then!). Saddle is a rather unusual Iscaselle with a strange miniscule speedometer or timer (?) mounted into the saddle nose!
650c Wolber Profil front wheel and Zipp 1150 rear disc 700c wheel.
Italian-made Rossin frame all the way from Sweden. New Old Stock. Frame never been used apart from me (approx. 50km). I have since been told this batch of frames were specially commissioned (purple and pink) by a bicycle shop in Sweden owned by the 60s and early 70s pro Gosta Pederson and his brothers, a contemporary of Merckx. (p.s. I know those Scott TT aero bars are around 1989 or 90 and are not period correct, but I like them)
This bike is hardly ridden. Hangs on my wall as art. Annoys the wife and kids but I think they are beginning to understand it is rather special especially since it was used in a NSW government Bike Week display last month. One needs to be a contortionist to ride it for any length of time, so this 54 year old tries not to.

Shimano DX brakes, funky & very "aero" 80s style

These 37 year old aero brakes from SHimano demand around $300 for a front and rear set nowadays. Crazy money.

Really, I have a set on an old Shimano road bike.

Darn, I really should have found that out before Foo heard how stupidly priced they currently are. I have a pair of levers that need hoods, but I am currently using late 80s 105s, ie the double pivot design that actually works. What really gets me is that the only thing aero about the components was the name.

Think of it as an off grid super account

...and it was AX not DX, but I never know if people are joking because it looks a bit like DX. Not to mention Adamas/Sewepe.
