I don't think I can get an oem groupset/wheelset cheap enough if I go with Chinese carbon.
Plus I don't want to have to explain everytime someone asks who makes my bike

In fact people rarely ask me which brand is my Chinese frankenstein but because it looks good people keep looking at it from all possible angles with faces like "where the heck is this bike from?" That's funny enough

I use my speedercycling to commute to work in London a couple of times a week - more often that not I get compliments on the bike, build and paint job. That said, answering the 'where did I get' question it is quite complicated when you don't have much time!!!

Great lightweight build, and props for using 26" knobbies.

Makes me wonder if you could cram small volume 650B/27.5" XC tires into that F-602 frame & fork, to make it a 650B "monster crosser".

If so, your BB height would increase 12mm from ~270mm to ~282 mm (possibly higher, based on tire volume), since the 650B/27.5" wheel has a 584mm rim diameter, compared to 26" wheel with 559mm rim diameter.

I don't think that my bike is among the lightest ones. However it is a disc brake bike so I feel that it would be good contribution to this thread as there aren't so many disc brake bikes yet. And they say disc braking is the future so here it goes. Pacman and Pinky likes the bike too.

Also you should note that my focus has been on practicality and durability rather than on weight. Also things like power meter bring in more weight. The ST-R785 / BR-R785 combo is also very heavy when compared to cantilever setup. Also the cockpit is aluminium because it is cheaper to crash :).

My bottom line is: disc brake CX bikes can be lighish too. Maybe not near the lighter end of 7 kg but almost.

My bike weighs 8.2 kg in total. Sorry for not weighing all the parts separately. EDIT 2014-10-17: updated pictures.

* Frameset: Ridley X-Fire (50), 1260g (with bottle cage bolts and seatpost collar)
* Fork: Ridley X-Fire/4ZR, 560g uncut
* Brake / shifter levers: Shimano ST-R785
* Crankset: Power2Max Type S Rotor 3D+, 110 BCD 172.5 mm, 610g (crankset + spacers + bolts + Power2Max spider)
* Chainrings: Rotor Q-Rings, 34/46 (will change to Q-Rings 36/46 as the 34 is too small)
* Front derailleur: Shimano Dura-Ace Di2, FD-9070
* Rear derailleur: Shimano Dura-Ace Di2, RD-9070
* Chain: Shimano Dura-Ace, CN-9000
* Brakes: Shimano BR-R785
* Brake rotors: Avid HS1, 160 mm
* Handlebar: Zipp Service Course SL-70 Ergo, 40 cm
* Stem: Zipp Service Course SL stem, 90 mm
* Seat post: Zipp SLSPEED, 20 mm setback
* Saddle: old Selle Italia SLR Kit Carbonio Flow
* Pedals: Crank Brothers Eggbeater 3
* Wheels: Stan's NoTubes Iron Cross Comp
* Tires: Schwalbe Rocket Ron (rear), Schwalbe Racing Ralph (front), both tubeless
* Tape: Zipp CX
* Bottle Cage: some cheap plastic Elite

Finally got my Lugi weighed on an a Park scale... 16.1 lbs with eggbeaters (not ti). I could still cut seatpost and steerer some, as well as add ti spindles and probably get sub 16 lbs. I'm still loving the bike though, and probably won't change a thing (other than cutting steerer down).

I wonder only how you managed to set up Bottom pull FD working with top-pull cabling… ?

I can be wrong, and have plenty of examples for that ;)

Felt F1X 2014 53
Ultegra 6800 running gear
TRP HyRd
Cannondale Si Carbon chainset (not light) 50/36
Mavic Askium Disc, Michelin Lithion training tires 700x25
3t Alu bars/stem, carbon post, Prologo saddle
XT pedals

That's running in right around 8kgs. I've got some Planet x cx 38mm tubular wheels on the way, that should drop things down to 7.6ish I reckon, we'll see....no real weightweenies parts on there.
