Hello you silly cunt, just checking in to see if you have actually managed to get a life or if you continue to spend your days trawling this boring ass site. I see you now have a whopping 42k comments, your parents must be proud. You live a sad life remember that.

It is always a joy when someone returns to LFGSS and continues to share their useful insights and technical tips. Although we have been poorer without them, the option to fuck off permanently from a boring site has has clearly eluded him.

Hello you silly cunt, just checking in

My dearest Tyron
How your latest epistle brought joy to my heart, after such a long interlude! These three years I have much lamented that you had quite forgot me. 'Tis true that I have these past years lived a sad life, but no more, for my dearest beloved Tyron returns! I must update you with news of my family, as you are so keen to know. Sadly, I cannot say what my father thinks of my humble efforts on what you are pleased to call this boring ass site, for he departed this life almost exactly one year ago. Still, I take sustenance from the support I get on the maternal side, and mother's pride is as my daily bread.
Ever yours, with fondest regards,
Tester

Hah! There's a sizzle in that swizzle, fo shizzle.

Holy shit pics like this are what got me obsessed with track sprinting years ago! Is there a cooler pair of men alive? The full cinelli warm up suit is cool as

Maybe you should buy my mystery Castelli hooded skinsuit. I think it might be for winter time trials. It's got long sleeves and legs. It covers the whole body except hands and feet. The fabric is thin, similar to normal jersey fabric. The crotch isn't padded so maybe you're meant to wear shorts underneath. Or maybe it's not for cycling. Could be for luge or bobsled. It's quite old, from Castelli's previous life before it was bought by the Sportful people.

Are you by any chance the person recently accused of writhing in a gimp suit in public? Destroying evidence is bad enough, but selling on to some poor unfortunate is a serious moral lapse.

As they say on the web, photos or gtfo. (although a gimp suit may be too dark atwist for the bike-porn thread)

The evidence will be circumstantial if there is an additional suspect.

You're right, but I don't have the energy. (ME/CFS) I'll add it to the list of tasks to give my assistant when I win Euromillions.

This is a remarkable piece of engineering. Wonder why it never caught on 🙃

Used in the Kilo, an easier gear for starting. Those designs exploited a loophole in UCI rules and were banned right away.
I remember seeing Jocelyn Lovell on one he made himself, he might have been the first?

I think this particular one is merely a piece of artwork. For the two-gear system to work, both cranks need to attach to the same BB axle. This has separate axles.

This all begs the question: where lies the line between porn and art?

Imo the concept of the two gears for the kilo makes it porn. But I'm a kilophile.

Wonder why it never caught on

Because it solves a problem which doesn't exist, while introducing six new ones. It's not a feat of engineering, at best it's a folly which warns others against the consequences of falling for the delusion that shortening the wheelbase is a good thing.

where lies the line between porn and art?

It's not a line, it's a region of intersection on a Venn diagram

Except that bike wouldn't actually work for the kilo. You need a full BB axle for two fixed gears.

You need a full BB axle for two fixed gears.

No, if both gears are fixed and the same ratio, the split axle works. The "starting gear" kilo bikes had a low gear with a freewheel and a high fixed gear which was not fully threaded onto the hub at the start. After a couple of crank turns, the fixed sprocket wound onto the hub thread and bottomed out on the shoulder, engaging the high gear and causing the low gear to freewheel for the remainder of the race.

Yeah, but your left and right cranks would be rotating at different speeds with this bike. This one would only work with the same gear in both sides. (But Sean Wallace said this one was never ridden.)

Shaun Wallace's twin-gear kilo bike.

Shaun's description:

"A few people have asked how it works.
"The general concept was not original, Joclyn Lovell had used a 2-gear system beforehand, and I'll bet it goes back to those innovative years of the early 20th century.
"The main problem with the early systems were that on the starting line the cranks could so easily rotate backwards a few degrees, totally screwing up your crank angle and the point at which the larger gear kicked in.
"Plus there was no way to slow down as one side has a freewheel and the other side had a cog that unscrewed until it fell off. I believe that's why it ran afoul of the rules.
"What I did was to set up a hub with about 3 cm of thread, and screw a single freewheel on the outside. That left about 2 cm of thread inside of the freewheel for a 1 cm wide fixed cog.
"Each cog had its own chainring and chain.
"The fixed cog was initially set totally unscrewed untill it butted up against spacers inside of the freewheel.
"My starting effort was through the freewheel.
"For every rev of the crank the rear wheel would turn 3x and that small cog would turn about 3.6x. So the cog screwed inwards 0.6 of a thread per pedal rev.
"At some point the cog would hit the inner shoulder and would take over the drive, whereupon the freewheel would click as it slowly "coasted" the differential.
"By carefully sanding down the spacers between the cogs I could preset not just how many pedal strokes before the bigger gear kicked in, but I even got it to engage every time when the cranks were at TDC.
"So in the race I'd just count 10 pedal strokes and knew on the 11th it would be a bigger gear. I'd set it up a year beforehand on my Trinidadian friend Gene Samuel's bike.
"To start with I kept it covered as I figured it would be copied, and some tried. But they could never work out one crucial element: how to simultaneously tension two chains on the same side.
With the older method you could just twist the wheel a little and keep some worn chains (Jocelyn told me).
"I remember going through sheets of paper and formulas about calculating belt lengths (pre Google/www days !!)
"That mathematics and engineering I learned all those years earlier was finally being of use !
"I vividly recall on a bike ride having a "eureka!" moment when I suddenly worked out how to select pairs of gearings so the two chain lengths would differ by an exact number of half inch increments.
"I couldn't choose any gearing I wanted but I had some options.
"The system never failed or skipped a beat.
"I rather wish I'd kept it now, but at the time it was just a tool for a job. Just one of a bunch of things I came up with."

That's some proper kiloporn, TA

Anything before they started running the brake cables under the tape is so hard to date for me; could be mid 60s to early 80s AFAIK.

But the digital watch narrows it down a bit ;)
