Thanks for the input guys, much appreciated.

Seems to suggest wider and lower pressure are the way to go? I wonder if someone has done similar in mud?

After much searching the best I have come up with so far is this:

http://www.hedcycling.com/ardennes/ardennes-plus/ardennes-plus-sl

Rims are 25mm external width and 20mm internal width @ 465g. Rims are available on their own (known as the "Belgium +")

Lots of positive reviews abound:

http://www.slowtwitch.com/Products/Things_that_Roll/Training_Wheels/Ardennes_long_term_review_4056.html

Granted it possibly shows that my earlier choice was excessive (as pointed out by JohnnyNT) so now I am looking for a carbon equivalent.

Maybe, just looking for opinions, but I run front 35mm ID with 2.25" (57.2mm) on the MTB so the tyres are about 1.6 times the width of the rim and rea 35mm ID with 2" (50mm) so about 1.4 times the width. 24mm id with 1.6 ratio would be a 38mm tyre and with 1.4 it would be 34, so with running low pressures maybe not such a daft idea?

Appreciate the input though, what would be nice would be a largish ID road wheel, maybe 22mm.

Cheers,

Mike

Was feeling pretty pleased with myself last night after picking up a set of very reasonably priced DT Swiss hubs. Now feeling not so pleased as I am trying to figure out what would be a good compromise rim (preferably some sort of chinese carbon :) )

This wheel set will be running on my CX bike which I hope to race next season (for the first time) and I will also be doing a couple of CX sportives (off road endurance rides). For the sportives I plan on running WTB's 700 x 40C nano tyre tubeless and fairly low pressure, I thought this rim from light bicycle would be a good choice:

http://www.light-bicycle.com/wider-carbon-mountain-29er-rims-clincher-tubeless-compatible.html#.VOtNQ_msWLA

These rims have a nice thick rim bead @ 3mm and are relatively light whilst being quite wide (ID of 24mm) but I am nervous of the 40psi max pressure. I like the idea of the (relatively) large volume for the 40C tyre and the wide rim + low pressures, seems like it will make the bike a lot more pleasant to ride, not to mention faster off road.

For racing I am guessing I will have to go to something narrower (isn't the limit around 33C?) which presumably will need to be a higher pressure? Whilst I am sure I wont be heading for road pressures 40psi doesn't seem like it leaves much room for maneuver, I would like to stay tubeless for the races if possible.

Does anyone have any bright ideas? Is an ID of 24mm to much for CX? All of the CX rims i've looked at seem to be a lot narrower.

Many thanks,

Mike

Does anyone know the size of the set screw to hold the rear axle nut in place? it looks like M2.5 but confirmation would be great.


EDITED TO ADD:
Still not sure on size but on closer investigation there is a grub screw already in the hole but 2-3mm down the hole so out of sight. If I can find a small enough Allen key I will whip it out and measure it.

Can see that there isn't much room! but what's the best thing to do? Can always go with a thinner NN in January I guess. Doubt helicopter tape will do much good?

Have fitted tyres, 2015 Nobby Nic's 2.35" Front and Rear. Not much clearance to the frame and requires a very precise installation otherwise you can't get it in. Looks sweet though!

Used the American Classic valves (as Vipassana did) also used the wide American Classic tubeless tape, have XMIPlay's 35mm external 30mm internal hookless rims and setup one with with a tube overnight (and then removed the tube) and the other with a compressor. Really impressed that both will go for 3-4 days even without sealant. Hubs are DT Swiss 350. The oversize lugs for the 15mm Maxle at the front require a different centre lock lock ring, an externally toothed one which isn't the easiest to find.

Thanks for the replies guys, the parts are at work so hadn't looked at them much yet. Do I need a mount for a 160mm rotor on the rear of a 256sl? (just want to get one ordered tonight with the other brake bits if I need one).

Need to run the brake lines internally (256SL frame) so is it better to split the lines at the brake lever or the caliper? Presumably if you split the line you might just as well drain the line completely? Also do I need some sort of adaptor to run a 160mm disc on the rear of the 256SL frame?

Many thanks,

Mike

Have added build spreadsheet to first post.

Tyres arrived today (2015 Nobby Nics 2.35" @ 788g real vs. 725g claimed, so within 10% which seems reasonable.) with and wheels are ready to be picked up.

Most interesting weight discrepancy so far is the XG-1180 MINI CLUSTER (X1 Cassette) coming in @ 264g real vs. 315g claimed by SRAM, that's only 4g heavier than the XG-1199 (XX1 cassette) cluster!

Finally got the bits in my hands :) Pictures and weights to follow.

Uh oh... What is the offset of the fork and how can I find out? (possible newbie error coming right up!) never heard of offset before  :o

Thankfully only charged VAT, with the Parcelforce "clearance" charge it came in at £37. Bits should arrive Friday. :)

Hopefully that will be the case, although oddly I can't see any means of disputing the charges with the Royal Mail. Presumably I'll have to go direct to HMRC.

Anyway, hopefully I will have a card waiting for me at home which will tell me how much I owe!
