CS-092SL disc brake road bike build
« on: September 18, 2015, 08:32:24 PM »
I ordered a CS-092SL disc brake road bike frame from Peter at http://www.xmcarbonspeed.com earlier this week.  This is a disc brake thru axle road bike.
Peter estimates 45-50 days so I will be adding some more info on the frame, parts ordered, and ongoing updates in the coming weeks.

A little technical info:
It uses a BB86 bottom bracket, 100 x 15mm 100 x 12mm front thru axle, 142 x 12mm rear thru axle, and a proprietary D shaped seatpost that comes with the frame and fork.

It uses the new flat mount road brake standard, which can use a 140mm or 160mm front rotor (depending on the orientation of the front brake mounting plate, and a 140mm rear rotor (which can be changed to a 160mm rotor with an adapter plate).

My plans:
Mostly Shimano Ultegra 2x11 build
Shimano ST-RS685 shifters/brake levers and BR-RS805 brake calipers.
Hope hubs
TM38C-25 tubeless ready carbon clincher rims, 25mm wide, 38mm deep, no brake track(from Peter).
Carbon B6 bars (from Peter).
Going to use a 100mm stem I have laying around until I decide what length I want.

Edited to correct front axle size to new specs.

Looks awesome, when are you supposed receive your frame? I'm hoping to place an order in a month or so, planning ultegra di2. Looking forward to seeing your build.

Thanks.  Peter said 45-50 days on the frame, and 15 days on the rims, plus shipping, as they all had to be made for my order.

I will update as parts, from xmcarbonspeed and elsewhere (Ultegra, but not di2), arrive with weights and pics, along with my impressions.  Just keep in mind I am a mountain bike guy building a road bike as I find myself riding my hard tail on the road when the trails are wet/muddy.

Thank you for the geometry information.
I'm quite desperate to find a frame that suits my odd long leg/short torso proportions.

For now only the gravel bikes of the big brands seemed an option.
But this one, with a 90mm stem could do it.

Do you know the tire clearance of the CS-092 ?
Can we ride 28mm+ on it ?

Peter said the max tire size is 28. 

I hope I can still fit 28s on the 25mm (17mm inside width) rims I am getting.  That will be the first thing I check when the frame arrives.

I'm very excited to see your build thread.  I would like to build one of these frame soon when I have the funds.

Parts are starting to roll in.  If anyone wants weights or anything just let me know.
Ultegra cranks, derailleurs, cassette, and Hope hubs


The flat mount road brakes and 160(f)/140(r) rotors


Hopefully the rims ship soon so I can get the spokes ordered, and build them up while I wait, as patiently as I can, for the frame.

Thank you for the update.
Did you roughly estimate the final weight of the bike?

I thought the Hope hubs were not appropriate for a road bike.
On their website, they do not advertise it as such, may be just for their weight?

No estimate on the weight.  I am not going weight weenie on this as I weigh about 215.
I will post the weight of the carbon parts from Peter/xmcarbonspeed.com when I get them, and the final bike weight when done.

This frame uses a 15x100 100x12 front thru axle and a 142x12 rear thru axle so I decided to use the same hubs I use on the MTB as I am comfortable with them and the cost is quite reasonable.  I did have to change the freehub to a 11 speed shimano style, which can be done on the newer Hope MTB hubs.  I am also going with 32 spokes.  That way I can always use the wheels on the MTB with just a freehub change if I ever wanted to.  If I really love the road bike I will build some lighter wheels, still with carbon rims from Peter, later.

Edited as the spec on the fork got changed to 100x12.  Fortunately Hope has 100x12 endcaps available.

Are those mechanical calipers?

No, hydraulic, Shimano BR-RS805.

Hi Joelk, can you post the weight for the BR-RS805 brake calipers, I just purchased the di2 levers and they come with the BR-r785. It looks like the frame supports the new flat mount design. The BR-rs805 looks to add a cleaner overall look on the bike. I didn't know these were already released.

Yes, the frame and fork use the new flat mount road standard.

When I ordered the frame nobody had the flat mount brakes yet, but about 2 weeks ago the shifter/brake set came into stock at Bike24.com.  Just the calipers themselves also appear to be in stock https://www.bike24.com/1.php?content=8;navigation=1;product=141700;page=1;menu=1000,4,320,322;mid=931;pgc=0 there too.

The bare caliper weighs 111 grams, the pads weigh 16 grams, and the mounting plate for the front adds 15 grams.

If you want any more info or pictures, just let me know.
