@rapsac, Nice bike! It looks incredibly to mine! Same brakes and rotors, derailleur, and light carbon parts where you have them. Just a Lauf fork that makes it around 500g lighter :)
Do the xpedo pedals offer some play, or are they rigid like SPD?

Thanks, like your Lauf fork. Was thinking about it, but the Reba works ok for now.
Really like the Xpedo's. Durable (replace the cartridge bearings, 3 per pedal, of my oldest set recently) and easy enough to use. Feels like SPD, a little bit harder to clip into (small difference), just as easy to get out. Float more or less like SPD as well.

Very cool bike! I get a few questions if you don't mind.
1) Decals.
Have you applied anything over the decals? Clear coat? Nothing? If nothing, does it get damaged easily?
2) Rotors.
Do you experience any pulsing with these very light rotors? Fork wobbling? Do you feel they don't break as hard as regular rotors?
3) Seatpost.
That seatpost seems very much out of the frame. Are you sure you get enough length inside?
Thanks. In answer to your questions:
1. Vinyl stickers, no clear coat. Sort of like rim stickers. Replaceable item.
2. Some minor sounds. For where I live (no mountains, only some hills) they are fine. Do a www search on them for other opinions.
3. Yes

Looks very nice! Great work  ;)

And still lots of potential to build it more lightweight! The syntace seatpost, handlebars, and of course the tires.. For me they were difficult to seal too. I changed them for Schwalbes. Lot easier and lighter..
You could also run a 11-speed chain on that 10-speed cassette to save some grams.
What do you use as chainstay protector? Looks interesting!

For what purpose did you build the bike? Do you think the range of the cassette will be enough?
I ran the exact same setup last racing season and found that it is to hard on long distances, especially in steep climbs.

Thanks. Yes, could be lighter still. Some lighter stuff is on my Anthem X29 right now. It is a bike for local tracks and I live in The Netherlands. So 1x10 is ok. The protector is Slapper Tape.
I have used various Schwalbe tires a lot, but for my local tracks I like the RaceKing better.

Like your bike too!

Will use a Jagwire Elite MTB kit first and see if it works. If it doesn't, I can always drill out the hole and use continuous outer shift cable.

So, decided to use full length housing for the rear derailleur. Required some minor drilling in the plastic cable spacer underneath the BB.
Anti-rattle zip ties on brake hose and shift cable every 10 cm in the downtube, took me 1 hour to thread.


Getting somewhere. Old dirty wheels to see how it looks.

I run full hose, entering from the left(1x setup) on the 062.
However on the 256 I had to drill to run full hose.
I prefer this option since most of the year I ride on muddy trails.
But on the 041, I was not sure drilling it would work so I kept it as designed with hose fragments, and bare cable inside.

Ok, thanks (and other posters as well). Will use a Jagwire Elite MTB kit first and see if it works. If it doesn't, I can always drill out the hole and use continuous outer shift cable.

Perhaps I have missed it when reading all posts, but: What are you guys using for cable system to the rear derailleur?
"Continuous outer all the way through" or "Short outer cables at chainstay and headtube + bare inner cable inside frame" ?
It looks like continuous outer will not fit at the bottom bracket. However, when using short outers I am afraid that bare inner shift cable may cut grooves inside the plastic cable guide at bottom bracket.
See pictures below.

3 cable holes at bottom bracket:
rear derailleur (inner) cable / front derailleur inner cable with metal tube / rear hydraulic brake line


cable guide and cover:
rear derailleur inner cable slot / front derailleur inner cable slot


When using full length housing I thought of leaving out the cable guide (not using a front derailleur) and use a spacer between cover plate and borrom bracket.
This also seems to require drilling out the hole at the bottom bracket (a little bit too small for outer shift cable) and replacing cable entry ports (which are included btw). Although the shift cable entry port at the chainstay seems rather stuck in place...

Perhaps the solution is to run shift cables like Jagwire kits with full length inner housing?

So, ordered my matte finish 18,5" BSA frame on the 19th of June. Ordered on ebay from sobatostore, was shown as in stock.
Received a shipping notification on the 22nd of June and received the frame yesterday, the 4th of July (The Netherlands). So approx 2,5 weeks. Not bad.
Packaging was ok, no damage to cardboard box. Frame was packaged as was shown earlier in thread.

I paid $350 including shipping, declared value was a bit less. Import duties, tax etc was €65. So, total cost for current exchange rate is approx €380 including tax and shipping. Seems ok.

Included with the frame:
  • Installed are through axle dropouts with through axle
  • Installed are cable stops for non-continuous shift cables
  • seat post clamp (31,8 mm)
  • 5 water bottle cage screws, steel
  • QR dropouts
  • integrated headset: bearing race for fork, upper (1 1/8") and lower (1,5") bearing, split ring, bearing cover and some thin spacers
  • fork tube expander, suitable for carbon fork tube
  • aluminium frame protector plate for right hand side chainstay with 3M double sided tape installed
  • 2 cable stops for continuous shift cables and 1 closed cover

Frame weight with through axle dropouts installed, but excluding everything else: 1257 grams
BSA bottom bracket width is 73 mm.

I will post some pictures later.
