IMO you might want to stay away from track bike geometry if you are seeking increased downhill stability. Look for frames that have a longer wheelbase (longer chain stays) and a more relaxed head tube angle (less steep). Read up on head tube angle, fork rake, and trail. Understanding how those interact with one another and jointly affect steering and stability will help you find a frame/fork that meets your needs.

How will any of that help him get his feet back on the pedals why they get kicked off? Maybe he should look for a frame with good clearances for Ted shredding.

It won't.

He completely understands that his pedal choice is less than optimum, and within that context is also inquiring about frame geometry for an increased feeling of downhill safety.

He specifically said to ignore that pedal issue when answering his question about downhill handling.

He couldn't have been more clear.

Different frames will have different levels of stability whether one's feet are on or off the pedals.

I understood his question so I thought I'd offer an answer.

Velodromes do not have hills to either climb or descend, bicycles designed for use on velodromes are called Track Bikes.
These machines are strictly fixed gear and are not equipped with brakes, but require proper foot retention.
Track bikes do go round and round on Velodrome bankings quite well indeed. On open public roads with hills, stop lights and rough surfaces not so much.

Road bikes are designed for use on open public roads, some are fixed gear and are equipped with brake(s) and proper foot retention.
Road bikes go up and down hills with little drama if the rider is competent, absorb road irregularities and provide convenient stopping capability.

Each design has a required set of design characteristics to make it suitable for it's intended environment, google Track and Road bike design to elucidate.

For maximum street cred an old abused imported track bike purportedly used in Japanese Kerin track racing is most suitable.
For safe-ish riding downhill a road bike, with whatever drivetrain one prefers, equipped with proper foot retention, good tires and well set-up brakes in the correct frame size may suffice.

What is the best kind of spoiler to put on my car if I want to feel safe in my car with no seatbelts?

Thanks, looks like my not too short wheelbase and not very high BB work fine for me. The seep seat tube is compensated with offset seat stem and the seat is pushed back. I switched the 1" raiser with a moustache that is flipped over, slightly inclined and raised a little higher than the seat. Interestingly, the pressure on my arms noticeably decreases with more pressure on pedals-much more than when I've used the raisers. For now I have one TT brake, thinking of second one. I always apply little pressure on pedals when going downhill, since reading in these forums that it is the right thing to do, even though during this time I whish to slow down. Does somebody know if two bikes have the same trail but different combinations of front tube angle and offset, what is the difference?
When I need a quick reaction to stop or swirl to avoid collision or a hole, my feet can go off the pedals and from there the situation will deteriorate. So, I would like to increase my chances to recover from these situations through frame geometry and fit set-up. Speed and long distances are not so much of interest of mine.

Only experience and confidence will help you recover from loosing your footing. Getting a new frame is an expensive way to get around this problem when something like $10 straps will actually solve the problem 6KU Pedal Straps

From your description, it sounds like you want a touring bike frame, doesn't get more slow and stable than that on road bikes.

Frame anything has nothing to do with:

Once again Proper Foot Retention does, period end.

I'm really curious, do you have a phobia about using foot retention? You're making things much more difficult for yourself. Frame geo is not the answer.

I made calzones from scratch yesterday with spinach, summer squash and shiitake mushrooms with fresh mozzarella as filling, together with artichoke heart tomato sauce.

That sounds delicious.

I am a big fan of food retention!!!

And, I really like my Langster.

By the way guys, thanks for leaving the food joke for me, a good Fuji beats a Honeycrisp, and any Italian blood in our calzone maker???

Every person I know that rides fixed rides with some sort of foot retention. I have ridden SPD's for the last 8 years or so and will continue to do so, on all of my bikes. 2 "track", a fat bike and whatever else I decide to get. OP is creating all kinds of problems to solve but has the answer right in front of him/her. They choose to ignore the suggestions made by MULTIPLE people here from new to senior members. You cannot help those that do not want to help themselves.

Problem is that OP is comparing geo of 55 kilo to 54 purefix when he should be comparing to 53 kilo. Should have started a thread on kilo tt sizing first noob the end

I am not naming any names, but some of the questions asked in the SS/FG forum seem to indicate a very low standard of intelligence among the user group.

Just occurred to me that maybe OP is contemplating some kind of stunt like going down Mont Ventoux with feet on the top tube.
