I found 2 K's in the parking lot. I think you dropped them.

How about an aluminum 29er at 18.72 without pedals? Specialized Chisel and loving it. Just finished it today and a big shout out to the crew at OC Bicycle Garage in Lake Forest, CA.

World's lightest dutch style city bike?

Ok this was for fun. My girlfriend wanted an upright city bike style and I had some leftovers and didn't want it to be one of those 30+ lb junkers that would be a pain to haul around.

Breezer Beltway frame - only ~1400 grams, could not find a carbon step through frame but impressed with the weight of this one
Exotic carbon fork, alu steerer 770 g
Pacenti TL 29 rims, Sapim Race spokes, alu nipples, BHS 72 POE hubs cheap and light and durable 1400 g or so
Thunderburt on the rear, 575 g
Conti Race King front ~ 580 g
Kalloy Uno 7 120mm 117 g
Deore level hydraulic brakes
KCNC ti pedals 150g/pair
Sunlite Santa Cruz alu cruiserbars. These are quite light, but these dorks don't publish weights that I can find
Ashima rotors 180 and 160 mm, 91g and 116g
Old school square taper XT level cranks with hollow ti spiindle

That's what i threw together. I even ripped the cover off an old cushy Schwinn saddle and glued it onto an old normal saddle with carbon rails. Alas, kind of disappointing final total weight of 24.2 lbs. I thought it would be lighter, things like the handlebars and cranks are heavy. Curious of others who have ventured into trying to get a lightweight city bike going on.

 

[fdonavan]

Awesome--way to put those spare parts to work! What is the total weight?

 

[rumblytumbly]

Total weight kind of disappointing at 24.2 lbs but I'm not going to throw money at it. Still beats what we were finding at shops. It was a true pleasure being able to dig through the parts bin and make so many old parts functional again. Thanks!

20.9-lb FS 29er, M9007 Pro-Mance frame with ultralight T800/T1000 construction. Initial plan was to stay under 20 lbs, but the frame came back 200g heavier than expected, so I kind of gave up. I could still get it under 20 pounds by switching out Maxxis Ikons for Rocket Rons, going stingier on sealant, getting a boutique seatpost, and switching to eggbeaters. But at this point it's just a race machine with a few extra grams over 20 pounds.

I do not think Pro-mance can offer T1000. As far as I know they offer best T700/T800 frames combination and call them SuperLight.

Mind sharing the components you built up with? I just picked up the exact same bike (color and all) after having a chisel that I had sitting around 21.5lbs with 'real' and budget-minded components

Carbonda FM936

Mostly XTR 11sp

Still need to final trim the steerer tube once I get the cockpit config finalized.

Under 21.5 ready to ride with pedals, cage, mount & wireless speed sensor.
