Borrowed some scales and mine weighs 21 lb, assuming the scales are correct

I thought it might have weighed less, are the standard Jake frames a bit heavy?

Fulcrum Racing 7 wheels
Maxxis raze
Forks are some older Planet X carbon (but they aint crazy light actually)
Campag Centaur 10 speed
Ritchey Bars & WCS stem
Carbon post, cheap but pretty light
Tektro CR520 brakes
Shimano 540 pedals
Rocket V saddle (I know I could get lighter here but it seems to be the only saddle I get on with)

No idea about mine but sure it weighs a fair bit more than that (Crosslight Kinesis 4), my pompino certainly does.

This is mine, weighs 20.4lb on the shop digital scales.
Admittedly I could drop 1-2lb off it by changing the chainset and BB, it's just a heavy generic Shimano square taper on a cheapish Stronglight.

Edit: Phone pic so sorry about the quality

I seem to remember mine was about 18.5 or something, Kinesis Crosslight Evo, full Ultegra 10 speed, Bonty Race X Lite wheels etc.

Racing 7s are heavy as hell (and a horrible, dull ride too).

my columbus xwing weighed 18 pound but my new surly xcheck weighs a ton 😉

18.4, for however much it matters (58cm). Trek XO2 – Bonty Race X lite wheelset, decent groupset and a smattering of carbon helps. Bonty's ride lovely too.
Newest one weighs even less I think. Pack it up with mud and it don't matter too much though.

23 or 24lbs I reckon. It's not light but then neither am I 🙂

Giant TCX – 18.75lbs
Ultegra compact g/set, Mavic ksyrium wheels, Ritchey WCS carbon post stem & bars, Spec. Phenom SL saddle and Kenda small block 8 tyres. Frame weighs 1420g.

I thought it might have weighed less, are the standard Jake frames a bit heavy?

Well yours weighs a pound less than a stock Jake, even with a fairly unremarkable wheelset and some beefy forks. The frames are pretty unflashy for a CX bike and my GF's Jake the Snake is a bit lighter, but they are tough and not that heavy in the grand scheme of things.

all good points

on the plus side its 7 lbs lighter than my Inbred 🙂

Mine's 21lb with heavy wheels.
Scott CX Comp.

More than my full-sus MTB 🙄 Never actually been on a scale, but I'd guess 22-23lbs on that basis.

My Major Jake is 23lb with mtb hubs and cable disc's although the scales are a bit suspect

About 17 lbs. Ridley X-Night frame, Ultegra compact chainset, Dura Ace bits, Thompson post, USE stem, Ksyrium ES wheels.

As has been said above, nearer 27 lbs when muddy no doubt.
