Hey folks,

First time poster. I’ve always been a weight weenie, and the great “style guy” from Bicycling magazine was/is my hero. RIP. It’s not about HOW you ride, it’s about WHAT you ride, and how you look while riding it! 😉

Anyway, I’m looking to build a gravel/cx bike to ride on the rural gravel backroads of my county in Virginia. I wish I could outright buy a complete featherweight machine, but alas, I do not have the funds. So I’m looking for recommendations on some of the lightest frames available, and I’ll build the rest with parts from my current anchor of a cx bike. I’m looking for a frame that will weight in under 1000g. I’d be riding a 52cm (+/- 1cm), so I know its possible. I’ve been drooling over the Specialized Crux S-Works, but dang that $2,800 price tag has me sweatin’!

I’ll end up using this bike as a road/gravel/cross combo. In a perfect world, I’d have enough money to buy another set of wheels to swap out when I want to ride the road, but for now, I’ll have to swap the tires only.

Thanks in advance for your input!

The entire crux line uses the same frame which is around 925g for a 54cm. So you can get a used 2018 full bike for ~1000 less than the price of the sworks frame.

Caveat though - max tire clearance job on the rear with 4mm of room is 700x38 slick and 700x35 knobby. 650b adds only about 4mm on top of that but drops the BB a ton.

If you don’t mind the funky cable routing and don’t weigh a lot the first gen Exploro is a decent cheaper WW option. So is the Open U.P. But that tends to be pricier than either the Exploro or crux.

For a budget option either go Chinese open mold or the Diamondback Haanjo. The Haanjo supposedly has about a 1050g frame weight in a 54 so the smaller size might dip around that 1kg mark.

My 56cm Cannondale SuperX is 1030grams, so a 52cm should be under 1000grams. If you can find the previous generation SuperX, pre 2017, they were even lighter. Quick release dropouts, external cable routing, steeper head angle etc.

A Parlee??? I don’t wanna have to give up my first born! (Although sometimes it’s tempting...)

I have recently been looking at a Scott addict CX. Frame weight listed at 970g. (Probably for a 56cm.) I bet the 52cm is closer to 900g

My Open U.P.P.E.R. frame in size M was 880g for the frame and another 380g for the fork with uncut steerer. It comes with nice light minimalist Carbon-Ti thru axles, a Cane Creek 110 headset, seatpost clamp and a spare derailleur hanger.

For weight Weenie purposes, r2-bike conveniently provide photos of the frame and fork on their digital scales.

Ibis Hakka MX frame should be around the 1000g mark if I remember correctly for a size M. Fork on the newer ones are Enve Gravel Fork

The Scott Addict CX or Gravel 10 (the HMX carbon frame) sits at around 890 grams for a size 56 and I think the fork is listed at 360 grams. The Specialized Crux is just a wee touch heavier than that.

If you're budget concerned I would look for a (used) Focus Mares.
Or for for the open mold discussion.

I think Louis is hitting it, a cx racer that happens to hit the big tire clearance mark would help you get low weight and budget ( since you can find them used...heavily used).

Norco Threshold Sl is, reportedly, a 990g frame.

Focus Mares CX is also a sub 1000g frame in a medium.
