I've always liked the legendary Trek Y Foil, not only do they look so damn cool 'still' they actually ride really nice. Of course getting banned for being to fast for the competition soon after their launch back in the 90's they're now quite rare.
However they are getting quite long in the tooth so why not rebuild one and I mean a massive 'rebuild'.
Add lots of new swanky components carbon bars, stem, seat post all the usual. That's easy, go deeper than that get into the core rework the frame. Rebuild and modify the very heart of the thing, build it as light as possible and bring it bang up to date. Sit back and enjoy as this long term build unfolds :-)

Here's where it all starts your regular everyday if somewhat played with Trek Y Foil.

Just a taster, I'm putting some pics together :D
Image

Image

You'll just have to flick through the thread to see what stage its at....
Image

Image

Image



As this build continues major changes in design diminish. Its down to detail now, little tweaks here and there thats where refinement occurs.
Stealth coloured Dura ace Di2 front and rear mechs, integrated carbon rear light mount, handmade carbon integrated stem/bars.
Image

Image

Image

Stripped of parts... and so to work.
Image

Paint removal
Image

Back to naked carbon...
Image

Custom made pieces...
Image
To be continued... :D

Can't wait, I had 2 of these back in the day. Loved them, even climbed Mt. Evans on one.

Heres a quick pic of how my Y Foil arrived from the States to UK. Well used and obviously set up as a TT complete with disconnected brifters and bar end shifters only.
Full Dura Ace which was nice.
I almost s@@t a lung getting it out of the box, it weighed in at a hefty 10.23kilo

Image

Most parts came off easily until time to remove front forks. I tried every trick in the book, heating, WD40 upside down overnight, leverage with bars, googled it, Youtube'd it. Nothing worked, steel steerer tube and alloy stem had become one after years of being dripped in sweat. Eventually brute force was the only option.
Image

Finally stripped down the frame weighs 1.851kilo. Still quite hefty, these things were built to last they are actually a hugely strong frame. When riding its almost like having two frames beneath you, whilst sitting you are cushioned from road vibration and bumps by the slight flex offered by that beam. Stand up and push and you instantly feel rigid feedback, the Bottom bracket area and entire rear triangle is renowned for being immensely strong.
Image

Removing paint brought weight down to a surprising 1.652 kilo, still no lightweight.
Image

Bottle cage holder made of cast alloy 44g.. gone
Image

Front mech hanger 46g.. gone. I have some plans for a replacement.
Image

Original English screw in Bottom bracket 88g.. gone. This didn't want to come out easily, I also have plans for this area of the build.
Image

Rear dropouts 131g .. surely not.. yep gone.
Image

Having removed bottle cage holder, front mech and also the rear brake mounting stud gives an opportunity to further reduce weight and modify that whole frame area. Fortunately Treks original frame construction method aids this. Well it leans in the right direction to help with modification at least.
These original 3D conception drawings from way back in the early days of this frame design show how it all went together. And what goes together can also come apart again.
Image

Time to build a 'new' lightweight upper carbon seat stay section complete with moulded in front mech hanger.
First stage is to shape a mech hanger
Image

Stick it in place and create a plug ready to form a mould.
Image

Image

Image

Carbon part straight from the mould ready to clean up
Image

Initial dropout plug
Image

Image

Image

Image

Straight from the mould
Image
Image

Dropouts will become an integral part of the rear forks
Image

All new PF30 carbon BB ready for final bonding
Image

Heres an indication of where its heading. That hideous piece of metal tube bonded to the BB area is temporary, its my point of reference for the front mech hanger and will be removed once everything is in place.

To be continued.

Subscribed... because this is insane!

Although you're (rightly) obsessed with losing and then mount an Ulegra Di2 front mech on??

I know I know, I was on the verge of upgrading to a newer traditional Dura Ace and do have the parts to go down that route.
Then I rode a Di2 equipped bike! wow just phenomenal, Im just waiting for a Di2 battery to arrive then i'll compare the two options and make the decision which way to go its looking 90% Di2 though.
Im building this to enjoy riding it and I just like the idea of Di2 for this build. Im aiming for sub 6.8kilo finished weight, if I can reach that with Di2 I will be happy :D

I will make them smaller from now on, Im quite new to this posting thing. Cant seem to edit what I've already posted once someone has replied. Is there anyway to do this?

Ha ha, thanks.
I'd rather build something a bit nuts rather than just screw a load of components together.
I hope it all works out now I've posted it for the World to see :lol: :roll:

Reckon you've just destroyed a nice old frame. Why didn't you just make one from scratch?

I guess thats one way of looking at it. The way I see it yes it is a nice old bike and yes it could be preserved in every authentic detail and maintain it as it was on its first ride. But then where's the fun in that i'd rather do something different. They were built at a point in time and at that time were at the very top of the Cycling tree in terms of design and technology (carbon bikes.) But they are now old hat, I dont see them as sacred there are still lots of Y Foil's on various forums (this one included in original form) many now have lightweight forks, wheels etc all the usual modifications and upgrades. Well why not go a stage further? try something that hasnt been done before. I probably could build a frame from scratch and it would actually be easier, but for this project I would rather 'Hot Rod' an existing Y Foil.
If I get this one to work as i'd like and enough people said "Build me one" I would make some moulds and build a few, who knows.
With the correct geometry and a few tweeks this frame design would still make an ideal TT bike.

Im not a total bike butcher though, I do love this era of bike from Trek and own other examples. I have a standard Y Foil frame hanging up, also a few Trek Y22/Y33 Mtb's. I must admit though this isnt my first offence. I have a previous conviction for attacking a Trek YSL200. That was their flagship super lightweight mtb at the time. Foiled only by the utterly useless rear suspension setup which they marketed as technologically advanced when in fact it only worked when seated. Standing up on the pedals transfered all your weight to the unsprung side of the suspension, not much use on a mtb!
My conviction was for cutting one of these frames up and starting again with all modern suspension and components etc. It now has modern geometry with 150mm travel front and rear, due to the lightweight frame even by todays standards it still weighs under 12kilo.

I can't wait to see what you have for a finished product. I love these builds where someone takes something and improves on the original design.

This is getting very exciting, exactly like reading a suspense novel! Darn the cliff hanger.
