Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Trek compact only

2020 Treks all compact crank. I wonder how many are rim brakes?

Says the guy running DA DI2 53/39 12/25 rim.

The world changed. Old bikes still work though.

I like my 53/39 and if I were shopping for a new bike, I'd be disappointed if only 50/34 combos were available. OTOH, SRAM now has a 10 tooth cog on its 12 speed cassette....

I guess they figure they'll have the wrong spec for a certain percentage of buyers anyway. This probably ticks off the smallest number of potential customers. If the customers want compact, give them compact. (And if they want 52/36 or 53/39, they know how to solve the problem.)

Especially since Trek is the only bike manufacturer on the planet.

I remember grinding up Mt Evans, The Tour de Gila, Tour of Utah, etc 53/39 and 11-25 on steep days and 11-23 most days. I even thought I was "spinning". Turns out I was just young and strong.

I ride 50/34 x 12-30 now. I'm slower but it's not because of the bike. I really would like to take the gears I've got now and apply to the fitness I had at 25.

Yes, I'd regularly hit 50's. I think the most I recorded was 58. Pretty sure I wasn't pedaling any of those times.

Trek aren't dummies. How many top pro's are riding sustained speeds where 50x11 just doesn't cut it?

The reason I hate compacts isn't about top speed... a 34 or 36 runs out right in the middle of typical cruising speed, which is just dumb. And the smaller the ring, the bigger the gaps between gears, not to mention higher drivetrain friction.

34x14 is good for about 20mph. If I need more speed than that, it really isn't much of a climb.

Why would you try to cruise in the small ring anyway?

Exactly
With rear cassettes typically having a 28 or larger you can cruise on the big ring around the middle of the cassette. In fact you can virtually treat it as a 1x11 and just drop it down to the small ring when you get to a proper hill.
I like the 50/34 set up.

Right, which is why Trek's bikes should really come stock with 44-28 subcompacts.

In street clothes, a 39 is good for everything except downhill and tailwinds.

Yeah, that works with a standard, where you hang out on the small ring at low speeds until you're going fast enough to shift up.

You have to think differently with a compact. I use mine exactly like @Dean V -- stay on the big ring preferentially, shift down to the small ring (practically a granny) only when you need to climb a steep or long hill.

Does that include P-1 builds also? I know you can get rim brake Madones in a frame set.

Just looking at recent mountain stages of the Tour it was obvious that they are using lower gears as their cadence is much higher than the days of Jan Ulrich grinding his way.

Maybe, but these days, they don't eat as many donuts as Jan did.

Plenty of Shimano 11 speed cranksets on Ebay in various sizes and combos. Get a backup and rotate them as you see fit.

Weird days when roadies gush over a bike because it fits 38 mm tires, claim that 30 mm wide rims are the "Sweet spot" and one of the biggest bike manufacturers on the planet doesn't even offer a full sized crankset on their top of the line road bikes.

I guess gravel is the new road.

Even funnier is back in the day, that is what the standard sport tourer from said companies was. You want a gravel bike, get you a French bike from the 60s/70s or before. They knew how to make bikes for crappy roads.

Definitely some weirdness there but I wouldn't say compact cranks was one of them. Your so called "standard" crankset was really just a blip the time line as well.
54/42 was common too. 52/39 as well. Plus others. Usually coupled with a rear cassette that didn't get smaller than 14 or 13t.

Gravel is a subset of road. I mean we're talking about gravel roads, and drop bar bikes.
