Fort 1.25DB Track and the rollers it lives on

Excuse my complete ignorance about how rollers and turbos work, this idea is coming purely form my head.

Would it be possible to get the turbo part of a turbo trainer hooked up to the roller? Maybe by making rubber strip on the rear roller to which the roller from a turbo could rest against, adding extra resistance. I'm guessing it's not quite that simple as there doesn't seem to be any such thing as a set of rollers with mechanical resistance, and I guess there is a demand for such a thing.

lol tester, have you been ghostin' ya whip?

Not exactly, but there are add-on resistance units for some rollers, e.g. Tacx Speedmatic, Kreitler Headwind

So why have you gone for the overbuilt heavy wheel option over one of those? Does it give a more realistic ride, or are you just flexing your mad scientist muscle? (I'd probably do the same1) :)

are you just flexing your mad scientist muscle?

Love it!

Also, magnetic brakes (Tacx) give a P=kv² curve, and I eventually want the curve to be dominated by P=kv³, per real life, and just adding a resistance unit adds very little inertia, again an issue with rollers (and even more so with turbos) which I aim eventually to address.

Tester, is this you?

Yup.

Don't that saddle cut in with the skirt?

Rapha?

Rapha?

That's a big skirt!

;0)

It has a lot to cover

My eventual aims are

1: lower rolling resistance by using larger rollers
2: add aerodynamic drag using a fluid dynamic brake
3: add inertia by a combination of the above

4: Exercise more?
5: Eat less?

Tester, I'm only pulling your leg. From your picture, I guess I'm about the same age and I was the same build as you. Now I'm a flying machine. If I don't make cat 2 racer this year, you will be the first to know. You can give me a plate full of ribbing!

Thanks for the post and I really like your bike. It shouldn't be indoors on rollers. ;-)

Those too. Obviously that pic is me full of a generous club dinner just after Christmas, so there's about 10kg to come off to get to my racing weight target.

And me.......

I was thinking about this project and how you could get more resistance. (Also just thinking about stupid engineering ideas). Could you make a compond drive?

one of these on the seatube

plus various chainsets with the crank arms chopped off? Chain line could be a little tricky I guess.

Compound drive would certainly have comedy value, but really my problem was not a lack of resistance per se (with the 56/9 gearing I was well short of running out of cadence head room on my 4 minute intervals), but the P/v curve of the resistance. Just driving the wheels faster doesn't change that.

Er, something missing?

Fort will be acting as crash test dummy for the T3 over winter, starting with this Fizik Tritone super cheap from Bike24. If it works, it's nice that the proper version comes in a good colour for the T3 and has integrated bottle carriage, if it doesn't it's no great loss.

Have you ruled-out an Adamo and SMP, or was this just a bargain?

With a narrow pelvis and big thighs, I don't fancy anything with a wide nose, so I'd need persuading that ISM was for me. The Fizik looks more like an SLR in plan than the others, which seemed like a good thing as I'm happy with the SLR in most respects. I really got fed up with waiting for the Selle Italia Iron, which would have been my first option, I might get one anyway when they eventually arrive for comparison. I nearly jumped on the half price Iron Tekno Flow , but in theory I can get the metal railed Iron and the Fizik for less than that.

Does 6.5 and 5.5 refer to the width of the nose? It's not clear from Fizik's blurb what the difference between he two is.

Have tried out Selle Italia's IDMatch, or are you going on what you already know?

That Selle is impressively ugly, even for a tri saddle.
