@JoelK, couldn't find the size of the frame your have. Can you please tell me ?

Sorry I missed this.  My frame is a 58cm. 
Still really happy with it.  No problems or issues.

The Hope rear hub will bolt right in.  The Hope front hub would need new endcaps for the 12x100 front axle.  However I don't think the Stans rims are rated for the pressures used on road tires.

I don't know if DT has 12mm endcaps for the 350 hubs.

I am approaching 1000 miles on this bike and am still very happy with it.

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?

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

Thank you very much for your pics and your quick reply.
I think the small vertical distance here is too close in my opinion.
A few more millimeters clearance there would make the frame perfect.

I will order the Xerxes tires and at least try it out for myself.
Chances are good. The spikes are mounted on the side of the tire:

But your tubeless Pro One's are probably a bit deeper.

The side clearance should be more than enough tough.

Martink, check with Bclem here http://chinertown.com/index.php/topic,809.0.html as he also got a 54 like you, and from his pictures there may be more room between the tire and the seat tube on the 54 than my 58.

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

There is pretty good clearance in the front, the rear has pretty good clearance side to side.  However, the rear tire gets quite close to the seat tube, that will be the limiting factor. 

I measure approximately 35mm width in the front fork and seatstays/chainstays.

Here are some pictures with 25mm Schwalbe Pro Ones mounted on 17.5 internal width rims.  On these rims the tires measure 28mm wide.  With these tires there is only about 2-2.5mm clearance between the tire and the seat tube.





Build progress is currently at a standstill while I await my machinist modifying my temporary front axle (cutting down a Shimano rear axle)/wait for Peter to ship the correct front axle.

Received the frame, fork, seatpost, bars, and bottle cages!  Everything came packed very well, and was in good condition.

I am very happy with the quality of everything!

Weights:
Frame 971 with guide tubing still in place
Fork 383 with guide tubing still in place (yes, the front brake line goes through the fork leg)
Seatpost 213
Bars (B6 style) 194
Bottle cages 22 and 23

The only problem is that Peter does not have the 12mm front axles yet. 
I will start building what I can, but the axle may hold me up.

I test fit my wheels with 25mm Schwalbe Pro One tires, which on the 17.5mm inside width rims measure 28mm wide, and they have plenty of room in the seatstays, chainstays, and fork.  The closest they come is at the seat tube with about 2-3mm clearance.  28mm tires on these rims would fit widthwise, but may rub the seat tube if they are much taller that the 25s.

I have played with 2x and 3x 32 hole wheels and I like the 2x a little better. 

A while back I was doing some reading and saw that in theory 2x is slightly stiffer laterally, but less so torsionally.  I had a frame where a 2.35 tire on a 3x 30mm id rim would rub occasionaly so, as I was going to build another set of wheels anyway, I decided to try the same setup laxed 2x and see what happened.  Same exact tire and bike, same brand and model hubs, spokes, and rims and no more rub.

Consequently I went 2x on this wheelset as I want to minimize the chance of tire rub when I try 28mm tires.
