Wow, I'd love to fit a bunch of coloured LEDs in those holes.

Drilling!!!

Drilling brake levers had one important practical benefit; it made them grippier even when your hands were sweaty. In campag levers it had nothing to do with weight loss; the OEM drilled campag levers were made from thicker material (so that they were not unduly weakened once full of holes) and were actually heavier than the undrilled version.

LF hubs are still alive and well, relatively speaking.

This Kirk precision stands proudly in our dining room....

best place for it IMHO. As a bike frame it was rather flexy, and wasn't as light as first billed once the thing had been made anywhere near durable enough. Anyone who has seen or used a Black & Decker Workmate Mk1 will have a strange sense of deja vu when regarding the Kirk frame; the reason for this is that the early type of workmate was made in the same way, i.e. from die castings. The castings even look similar in overall design; am I right in thinking that Kirk was involved in that development too?



After a fairly short period of time the workmate was changed to steel pressings, which bent when overloaded instead of snapping like a carrot.
One these ...

The Kirk bike frame disappeared by 1995; not sure the UCI had anything to do with it?

Good on him for 'having a go' and all that but IMHO the design is inherently compromised by the limitations imposed by the method of manufacture, moreso than with most other methods of frame manufacture.

A bit of history here, about the Kirk bicycle.

Hi,
More on dead end stuff-
DD pedals explained.
Dura-Ace EX stuff which included DD pedals (Dyna Drive) were in the 81 catalogue.
Along with Deore DD pedals.
Shimano aero dynamics were also mentioned for the DD pedals.
AFAIK 82 catalogue launched AX series Dura Ace, 600, Adamas.

Offset Crank Arm?

FPD = Full Power Drive.. what else

My 60cm frame measures 583mm from centre of BB to top of seat tube.

You cannot beat a nice l/f hub imho. These have the spoke holes a bit to close to their edge,but the bearings as smooth as silk.

Just remembered the Fals pedals in the garage. Sort of Speed play on reverse. A plastic knob for a cleat that wore like hell and soon fell out of the pedal. My first clipless.

Surprised no one has mentioned belt drives, or even more so, shaft drive. Apols if I missed them

Belt drives are rare although they are still kicking about. I have a Moulton TSR2 (chain drive), I've considered converting to a belt drive but the kit seems to be as rare as rocking horse teeth.

Only shaft drive bikes I've ever seen is on the hire bikes in Liverpool.

Oh and bench saddles too like the ones made and sold by Mister Winkle

Campagnolo SGR -1 clipless pedals .A nightmare to disengage from as I rememeber .

Hi,

[nigelnightmare]

Those tyres you dont pump or can get punctures as they are in some sense solid. ANy one here ever rode on them?

Yep!
It's like riding uphill all the time!!!
Great for training, but put pneumatics back on for the event.
Also a bit skittish in the wet!
