Marco Pantani: RIP. I doubt anyone in the last 20 years could hang onto his wheel on long steep climbs.

His 1998 Bianchi featured a 9-speed Campagnolo drivetrain. 54-44 rings and a 11-23 cassette.

If you weigh 125 pounds and crank out big watts, then you don’t need low gears; you just go fast.

It featured whatever he wanted it to feature, and even for him, that wasn't always a 44T inner ring.

Right: when Pantani used a granny-gear up front (39 tooth) he switched to a 11-21 cassette (clipped in picture).

You presumably don't have a 16, though? I spend 90%+ of my riding time between the 14 and the 19, on both my bikes (one a compact with a 12-27 10 speed, the other a 53-39 with a 13-26 8 speed). I want more options in that part of the cassette, and failing that, more choice at the low end. I have no use for an 11.

A few riders usually run compacts for the climbs now, although typically not the GC contenders. The problem with a compact is that the riders run out of top-end gearing. In a fast pack, riders need to be putting down serious power at 35+ mph, so that really limits the use of a compact. If you get gapped from a pack because you ran out of gears, you're done, you're never getting back on. For a 50x11, even the pros are done at about 40 mph.

On the mountainous stages, for many of the riders, it's all about just making the time cut. They can run a compact, save their legs, and now worrying about loosing an hour.

My '73 Motobecane Grand Jubilee came with a Stronglight 52/42 and a five cog 13/24. Cute little Jubilee derailleur too. So when I went XC tour Seattle to New York '76 on went a 15/34 and a LA Suntour rear D (can't recall model). Sure made hills easier. Except in Winnipeg I put the 13/24 back on, sent the other home thinking there weren't many serious hills east...was that ever a mistake of course I was young & dumb & full of bs.

People forget that Tyler Hamilton's compact was a 52/36 anyway, so not that great of a difference from what everyone else was running.

mid-compact and 30T for easiest cog is really a nice combination. There isn't really much you can't climb with the drive train.

Climbing in the big ring you drop your lesser competitors faster.

Be fair, we had 7 cogs on our Sun Tour New Winner freewheels in the early '80s.

The 7-speed New Winner was introduced for the 1979 catalog, actually.

Even you can learn some neuromuscular things.

of course it does. EPO=increased hemocrit=increase ability to shift power generation away from muscular endurance to cardiovascular endurance.

Kind of a funny clip of Armstrong commenting on Froome's gearing.

***EDIT: After re-reading the OP's post, I think I just posted Armstrong's comments he was referring to....
