After breaking my 256, here is my brand new CS-041
« on: December 18, 2015, 06:32:58 PM »
First of all some picture of the new beast  8)
I wanted it fluo green or yellow, but didn't want to deal again with the hassle of the Belgian customs, so it ended again all black.





As many others here, dealing with Peter for this frame was a pleasure.
And luckily he had it in stock.

I took most parts from the 256:
  • Lefty( freshly back from a warranty repair, the bottom piston was scratched/toast)
  • 30mm carbon wheels, with a rear DT swiss axle
  • XX1 cassette, this was my second and probably the last. Even with a new free hub, Shimano's are much cheaper
  • XTR rear derailleur and shifter
  • KMC X11 SL chain, as it was new, I reused it
  • Hope Evo E4 brakes with KCNC Razor Rotors
  • Crank brothers pedals
  • my beloved "aliexpress" carbon seat
  • stem and bar that came with my 256

Unfortunately the bottom bracket was only available in BB92 and the seatpost diameter is 27.2, not what I had previously.
  • I got a discounted Procraft seatpost from a shop here.
  • A carbon seat clamp from aliexpress
  • And had my "carpe diem" moment for the crankset and felt for a Next SL
  • An Absolute black oval of 34

It weights a nice 8.6Kg( 19 lbs ) with pedals and tire sealant.

Here are some random impressions from the build and my first rides with it:
  • The frame is clearly stiffer than the 256.
    I was used to feel a little flex when sitting just before riding. Here nothing, it is hard as a bench.
    This probably comes from a much stronger rear triangle
     
    Well, it is strange. When hammering the pedals or cornering it feels definitely stiffer, and do not forgive when you hit bigger bumps
     

     
    But at the same time, the 27.2mm seatpost is kind of elastic, and eats the small bumps
    For instance making our awful Belgian paved roads, all of a sudden, much more comfortable.
    Although, it took me a couple of rides to be used to this strange new floating feeling.
     

     
  • The oval ring, is something I would suggest all 1X riders to try.
    It is not a very expensive test and it can make a big difference(it did for me)
    Especially on steep climbs or when you push hard.
     
    As stated by Marcin from Absolute black, it definitely gives you an unfair advantage over your friends
    On the 256, I started with a 28 XX1, then moved to a 30.
     
    Then I tried the 32 oval, it was a revelation.
    But then the 4 smaller sprockets of the XX1 cassette were toast after just a year( I'll go Shimano after this one ).
    So I was definitely too small in front. And jumped directly to an oval 34(an "ovality" of 32/36)
     
    I clearly suffer more on some climbs, but I use the whole cassette evenly, and can even challenge some roadies now.

    Just have a look at the design of the BB30 ring: http://www.absoluteblack.cc/sram-oval-bb30.html
    For me it is an engineering work of art. The one I took off my 256, decorates my desk now :)


     
  • The frame arrived in perfect state, well packed and protected.
    The cable stops looks more finished than the 256.
    With various options to nicely plug the unused holes.
     
    Sadly the rear brake entry is still a simple and quite ugly hole in the frame.
    The internal routing was dead easy for the rear brake.
     
    For the derailleur, the inner hose looked well done, so I decided to try it(no frame drilling this time)
    It was very easy to route as well.
    Unfortunately the cable enters the frame on the right, and it makes a rather ugly curve, an need a sticker to protect the frame.
     

     
    Hopefully it will stand the mud I live in most of the year( I added some teflon at the cable end ).
    If not, I will go again full hosing, but it will probably be a pain to drill and route.
     

And finally some minor issues:

  • The drop out on the derailleur is different, there is no more an option to put a headless screw to tighten the nut
    And the axle seems 5mm too short, not coming flush with the nut. Not sure what I will do, but my rear-axle-peace-of-mind is gone.
     
  • The cable stop for the front derailleur is ugly and riveted( can't be removed easily ).
     

     
  • The headtube is 5mm shorter, making the lefty assembly less compact than on my 256
     

     
     

A couple more pictures before leaving:
 

 



Sorry my ex-256 colleagues  :P, but I definitely feels it as an upgrade.
It makes a more racy/radical bike.
The 256 was already great and sharp, but this one is some steps higher.

Sweet ass build! This will be good that we get a direct comparison between the 256 and 041.. seems initial impressions favor the 041. Interested to hear your thoughts comparing the two as you get more trail time with the new beast

Great looking build! 8)

The lines of the 041 are starting to grow on me.

Man...I'd love me some Lefty.

Question on the Lefty. Is there a Lefty where the two crowns are adjustable in height? I've seen some that look like you can. I ask that is because if I mount the stem above the upper crown...the bar will be too high. I already run a slammed Syntace Flatforce. I'll have to mount the stem under the upper crown. I've seen some people run it that way...but don't really know which Lefty or what adapter they used to mount it.  ???

Really liking the 041SL!  If anything ever happened to my 256 I would do the same as you.

@RS VR6, The Lefty 2 comes with 3 different distances between clamps (100, 113 and 126, but not adjustable)

And there are XL Lefty forks, that have 163mm between the clamps.

Very nice build.  I am on the fence about upgrading to the 041 and Lefty/RS-1 this next year or trying a Specialized Epic Carbon.  Either path will be a lot of money.   :(  You make a very convincing case for the 041, but new seat post, crank, BB, and fork will be expensive; that pushes me towards the Epic so I could have both  hardtail and a FS bikes in my fleet.

I am curious about how you determined your rear cassette was worn out.  Mine shows wear, but it still shifts crisp and with no noises.  I've got thousands upon thousands of mines on it at this point including many races and century rides (no relubes).  Could our riding conditions explain the difference?  Is mine worn and I simply do not realize (there appears to be no ill-effects)?  They are expensive so I understand your hesitation to replace.  I haven't even changed my chain yet.  I did need a new front sprocket due to extreme wear and I went Absolute Black Oval (which I agree with your assessment on their product and will try a 34T very soon).

The chain was jumping teeth from the 4 smaller sprockets when pushing.
Something you would definitely feel/hear. But it was still fine on the 7 bigger sprockets.
Putting a new chain didn't improve.

Visually, the cassette still looked good.
I contacted the seller( bike24.com ) send them a picture, and tried to get some warranty.
They told me it was worn out. And that many riders had the same issue, depending on how they cared about it...
I explained them I was cleaning/lubing the chain after each ride, and changed 3 times the chain. To no avail.

When I got the new cassette, I just swapped.
With the same chain, derailleur settings, etc. The problem disappeared immediately.

You are very lucky to have that mileage, with a single chain and cassette.
May be it is the mud. Or I may do something very wrong.

My upgrade was expensive indeed. But the business was good this year.
If my 256 was still fine, I could go for the Epic too.
Well... after a road bike, and may be a trial bike :)

It's a nice build!

Got the same oval ring (but in 32), and it works flawless. Might need a 34 as well for the flat parts on hard forest ground. Does that fit on a 256sl?

The 41 might be stiffer, think I like the looks of the 256 better. Lefty is awesome though :)

I can only say that Garbaruk 34T oval fits on 256 but very narrowly, AB ring is almost the same

I have an AB 34 tooth oval direct mount ring for the RaceFace NextSL cranks on my 256 and it fits nicely.

Thnx, an update I might consider when I notice to much wear on the smallest cogs in the back :)

@cnasta, I was riding an AB 34T with my 256 without issue.
It was the one for SRAM BB30 I referred above http://www.absoluteblack.cc/sram-oval-bb30.html

Re-reading posts on the 041 and I noticed I missed this. If I had to choose between an Epic Carbon and just about anything, I'd be choosing the Epic.

Still, looks like we're going to be getting an 041 for my wife, pretty stoked to get that build happening!

If you find your gear cable clogging up, before drilling out your frame, you could try these:

http://www.wiggle.com.au/transfil-flying-snake-gear-cable-set/

They come with a liner that goes between the inner and outer cables, and completely seals the inner cable from mud and water. I have then on a few bikes, included my road bike which has internal routing, and they work well.
