Can someone explain wtf is going on with that rear wheel (blimey, altitude, bit of BD and a mahussiv wheel.. Moser was certainly determined :roll: )

Is it not a smaller 650c front wheel? I assume Fab will be going for the athletes hour, where you have to use the same equipment as Merkx did, so standard wheels, standard frame, drop bars etc.

Maybe... but did you get to 0:55 in?

I've always wondered if that huge wheel actually works, but it looks awesome.

Looks like he's riding a penny farthing backwards.

I remember pictures of a chain ring nearly that size with a guy breaking the manual bike speed record being paced behind a car screen on the salt flats.

There's quite a few of them:
This is from 1973


This one's from the 60s


And this from way back in the 40s


But this must be the winner - also from the 60s (same rider as the 2nd one)

Thanks Rich - shows I'm not senile yet. :?:

David Le Grys used a similar custom oversized ring to set the roller speed record on Record Breakers:

The bike he used on his attempt at the outright speed record (on the then-unopened M42 being paced behind a TWR Rover SD1 touring car, which turned out not to be fast enough due to the drag of the fairing) used a geartrain based on tandem components instead of a massive chainring:

What was that in aid of? The guy must have some sort of superhuman strength, remember these other guys are riding behind cars!

That photo is Nik Bowdler and he rides that all the time (at ~60rpm) Seems to work for him, he's won the BBAR using it....

Similar to this from earlier this year:

The actual world record bike is quite disappointing with only a 70t big ring!

There is only so big they could go before size became an obstacle and the double reduction system was an effective if inelegant solution.

This all takes me back to a picture I saw across a double page spread in a then new cycling magazine from the mid 80s of John Howard riding at 152mph on the salt flats. That image has stayed with me to this day as it was unimaginable to me at the time.

Was it from this video or a different occasion?

There aren't many details in the video's description.

Fair play, I think my knees would implode trying to push that gear!

Isn't Laura Trott doing some speed record thing with Guy Martin soon?

It was on Channel 4 tonight. Laura Trott was advising him on the training methods the track team use to get maximum endurance.

It was was an interesting programme, with the record attempt on Pendine Sands being motorpaced by a full-blown race truck and with a aerodynamicist involved to work out the best (and safest) way of generating the required slipstream. Dave Le Grys also reatured in the programme, and the bike Guy used was a steel frame built by Rourke using the same gear reduction design as the one Cliff Shrubb built for Le Grys:

Quite impressed at Guy getting up to that speed. Not a surface I would have chosen, but no motorway available...

ProCycling this month is suggesting Sir Brad is on for a go too. Now that would generate some publicity if both him and Spartacus manage to go for it at the same time. Bring it on.

Martin would be a bigger draw I suspect.

Wiggins is probably a much bigger name to non-cyclists though. I want to see all three simultaneously, or all three on the same track, one after the other so no-one could claim they had an altitude advantage.

For sure. No-one who isn't into cycling will have a scooby who TM is.

I've known Cliff Shrubb for years, he lives next door and still build the odd frame if you nag him into submission; he never did get paid for that frame!
