Who makes the least expensive sub 20 lb. bike that will handle at least 32mm but preferably slightly wider 700c tires. Just wondering if anything is out there even direct consumer that I am not aware of. I am less interested in group set than overall weight. I have no problem assembling a bike.

You can get almost any bike down to sub-20 with enough $€ĄŁ in proper component selection.

My steel CX bike with discs that accepts 700x38's weighs 16lbs with pedals, power meter & bottle cages. It wasn't cheap. My steel disc mixte weighs 3 pounds more (19 with pedals, Powermeter and bottle cages, too) & cost 1/3 as much (partly because I had a healthy spare parts bin). Any carbon bike could easily beat this.

You might sharpen your question as it is so broad as to be unanswerable.

I am asking about something that can be purchased as a complete bike and assembled, not what can be assembled when buying separate parts from different sources.

WABI Thunder if you can get by with 1 speed. Fits 700x50c.

If you are OK with 35s, endurance bikes like the Giant Defy Adv are alleged to be about 17lbs.

17-19 Lbs. is what I am looking for. Just wondering the least expensive way to get there other than finding a used deal. I have an 18 lb. race bike but 25mm tires is the widest it will fit. I have several heavier bikes that will fit wider tires.

I think the stock Cannondale Topstone carbons are under 20 lbs. They are a few pounds lighter than the aluminum’s, my ALU is 22-1/2 lbs. I would imagine with some light carbon wheels you would see 18. Also pay attention to the tires to get something light.

Forgot to mention, I ride a 58cm.

Lowest weight for lowest price: there are probably other choices now, such as Canyon, but I bought my last two bikes from BikesDirect and have been happy with both. (I used to manage bike stores and got used to employee discounts for bikes. BikesDirect's bikes were the closest to that pricing I was able to find.)

Yes, their "Save 63%!!" banner reeks of hucksterism, but the bikes I bought genuinely were great values. As long as you know enough about bikes to install the handlebars and pedals and tune the brakes and gears, any bike you buy from them should be fine. Or just pay a shop to tune it up.

No weight listed, but might be under 20 lbs. You can always email them and ask which of their cross/gravel bikes are under 20 lbs.

I think that finding a sub-20lb bike with bikesdirect is going to be a tough search, and their gravity line is of cheaper quality and heavier weight that the motobecane line from what I've experienced. I fully enjoy my motobecane UNO and agree they can be a good value for the cost, but even the Ti bikes of theirs that I've built and weighted were fairly stout.

OP, least expensive is going to be a loaded question. With a modern hydraulic disc brake, scraping under that 20lb mark isn't always cheap or easy. Cross bikes are generally heavier to begin with being built with sturdier parts, but in the last few years a lot of brands have either moved to gravel with different less performance oriented geometry or bumped their complete bikes to ridiculous prices. Although it isn't what you're looking for, buying a frameset and building what you want might be the better way. Not certain what company has the lightest, but I'm guessing you'll clear 3k to get the under 20lb weight.

with some creative component swaps - my alum Topstone is 20.2 lbs … with original wheelset / Conti 700x40 Terra Speed tires and tpu tubes … ( it’s a XS size though )

With carbon wheels, some light tires, carbon bar, stem, seatpost and crank, you can get this bike near light enough to a standard carbon road bike. You have to shell out maybe $2000 or so over the cost of the bike though.

Probably Canyon (among the more well-known brands)?

But my first criteria would be fit / geometry.

Decathlon in Europe sell the VanRysel RCX cyclecross bike with a 1x11 GRX drivetrain that accepts 38mm tires and sells for 1600€ or about $1860. Claimed weight is 8.5kg or 18.7lb.
