Well it my wife's 40th this month so to celebrate I am building her a dream bike.

I have started with a frame and fork from Speeder cycles in China. yes the name is terrible but the frame isn't. It is Carbon fibre for disc brakes. Frame weight is 1060g and fork weight is 388g. The aero post is 200g. So quite light for money I paid.

I will update this thread as I build up the bike. I started tonight with the rear wheel. The rims I have chosen a 28H 38mm deep carbon tubular rim from the same supplier. I ask for them with no brake track and what they did is to not apply the surface coating to where the brake track would be, I am fine with that and it look good for a disc brake build now.

I picked the DT Swiss 240 28 spoke straight pull hubs because they are brilliant. Spokes are DT Swiss Competition with black alloy nipples. I have fitted an 11 speed body to it and the OLD has changed to 136mm in other words no real world change.
Rim weight is 330g.
Rear hub weight 232g
Wheel weight 736g

The rear disc rotor is SM-RT99 XTR 160mm because it is the best weight 124g with lock ring.

I have mounted the 11 speed ultegra cassette and the 22mm Continental GP4000 tub and the wheel weight is a shade under 1450g for the rear with a Shimano XT skewer. Not bad really.

If you are wondering what the rim is like to build with well it is excellent. It has built into a very stiff wheel and it took 1 hour in total. Tension is even to within +/-5% and radial runout is less than 0.2mm and lateral runout is of a similar magitude. When I stressed it the wheel did not budge. It is a good rim and wheel.

More to come! I love my wife I do not have a bike that will be a good as this.

Look like it will be a good build, looking forward to seeing the finished result :-)

DT Swiss 28H front hub stright pull 126g
38mm deep carbon rim 332g
Dt comp spokes + alloy nipples 189g
Total 647g

So wheelset weight is a mere 1383g! Light weight and very stiff

Front XTR 160mm rotor 124g
Pro Sleath EVO bar/stem 404g for 42cm width and 110mm length (claimed 350g so a bit over weight).
Cane creek IS42/28.6 upper assmebly (carbon) 36g
Cane Creek lower assembly IS52/40 42g
3 spacers 6g

That's it for tonight

More done
DT Swiss 28H front hub stright pull 126g
38mm deep carbon rim 332g
Dt comp spokes + alloy nipples 189g
Total 647g

So wheelset weight is a mere 1383g! Light weight and very stiff.
With both rotors, tubs, XT Skewers and cassette (no glue yet they are stretching) weight is 2523g not too bad.

Individual part weights might as well weigh everything.
Front XT skewer 53g
Front XTR 160mm rotor 124g
Pro Sleath EVO bar/stem 404g for 42cm width and 110mm length (claimed 350g so a bit over weight).
Cane creek IS42/28.6 upper assmebly (carbon) 36g
Cane Creek lower assembly IS52/40 42g
3 spacers 6g
Rear Conti GP4000s 22mm tub 267g

I got the r785 calipers fitted and the hoses mounted. I had to do a small modification to the BB shell area with a small file to allow the hose to pass through the internal routing guide there as it was only meant for 5mm casing not fat hydraulic line hose!

I have also positioned the seat selle Italia Flyte flow and the handlebar to centre line of seat post is spot on for my wife, phew otherwise that would have been allot of wasted money on the bar stem combo.

It's getting better and better.

I'm curious about final build.

Frame size?
Angle between fork blades and steerer tube looks a bit slaggy.

Final weight is 7.7kg but the shifter are over 500g so they are a bit porky to be honest.

Spec list
Speeder cycling framsetand seat post 52cm with 53.7cm virtual TT
Selle Italia Flyte Flow saddle
Pro Stealth Evo bar/stem 110mm 42cm
Shimano R785 STI and calipers
Wheels 38mm tubular carbon rims with no brake track, DT Swiss comp spokes, 28 spoke DT Swiss 240 straight pull hubs with a 11 speed body
Ultegra 6870 Di2 with 11-25T cassette. This is my only gripe such a poor choice of cassesttes as I wanted a 12-27T for this bike.
Chain is campagnolo record as Madison are out of stock of the DA 11 speed chain at present.
22mm Conti GP4000 tubs.
Shimano A600 pedals

The angle you ask about I do not know but in this link dimension G is 43mm.

I am planning my own version but given I am campagnolo man I have the Super record RS shifters and mech anf the Overtorque chainset with BSA cups which will be mated to this frame and I will use the same wheels. Brake will the tektro Spyre when the hit the shelves. Unless of course Campagnolo release there hydro brakes later this year.
The brakes bleed up O.K but the lever is not hard it is very progressive

I like it - wheels are lovely. The hoods seem a long stretch, is it the angle or the Di2? Also at 420mm the bars seem pretty wide for a lady?

My wife has broad shoulders she needs bars that wide. The hoods are long, I am not sure why maybe it is the braking system as Di2 can be made very compact if Shimano wanted it to be. In fact if you think how long a MTB brake body is and turn it lengthways it makes sense that the shifter are a long as they. The future will be one of long hoods.

Then it´s the angle of photo, because my road frame has also 43mm and it´s OK.
But my CX bike has 50mm and the steering is very slow.

Have you ridden the bike? How is the steering and overall feel, stiffness, comfort?
Will the frame take 140mm rotors?

It may have taken an internal battery but I was not sure if it would fit poperly in a aero post so I played it safe.

The frame is too small for me to ride for any distance, I need a 58cm. This is for my wife remember but it feels fine, stable stiff just right really. It would take 140mm rotors but I think that is a bad idea. Disc brakes can get hot and the bigger the heat sink the better. 140mm rotors on the front could be overwhelmed anywhere that is not flat.

I will be able to a better write up when I build mine which is coming very soon once I sell a few bits to help pay for it.

I would double check on the rotors. I have the CX version of this bike from Speeder and it is minimum 160mm at rear.

I may be 160mm size but since I would never fit a 140mm rotor to any bike it does not really matter to me. The is being a weight weenie and there is being unsafe or at the very least restricting your bike to the flat lands only.
