29er / CarbonSpeed CS-MB01 Frame

« on: June 16, 2015, 01:40:01 PM »

So Carbon Speed now has this very nice frame http://www.xmcarbonspeed.com/Productinfo.asp?f=1392:

Anyone know what the thingies in the back are? Some vibration reduce system but does it work? Does anyone seen this before?

This is also present on this road bike frame: http://www.xmcarbonspeed.com/Productinfo.asp?f=1391

Other than that the frame looks awesome.

29er / Carbon Rims advice - Hookless or not when tubeless + setup experience?

« on: May 28, 2015, 11:41:45 AM »

The title says it all - carbon rims - hookless or not when tubeless?

Hookless rims should be stronger, but setting up tubeless is more difficult. How well do they hold on and how often you need to pump them?

Which rim width is the way to go and which tire are you using? What pressure can you run safely without burping?

Any experience with how to setup them is also welcomed!

29er / Fast 1x11 gearing on carbon frame - YFY-BM-01 or WCB-M-062 or other?

« on: May 28, 2015, 08:59:09 AM »

Which frame has been more proven and which would be better to get?

YFY-BM-01: http://www.yfy-carbon.com/en/pro_detail.php?id=20

WCB-M-062: http://www.workswellbikes.com/web/view/149.html

Any other frames out there?

I like the workswell geometry better and I don't like the YFY head, but workswell seems to me unknown and unproven.
Also I need to note that I would like to fit 40T chainring 1x11 SRAM up front (does anybody have 1x11 setup on chiners and is the clearence between frame and chainring plenty to fit this huge ring?)

29er / SRAM 1x11 drivetrain in BB92 frame

« on: May 28, 2015, 08:42:03 AM »

Couple nice frames have BB92 option only (YFY-BM-01: http://www.yfy-carbon.com/en/pro_detail.php?id=20, CS-041: http://www.xmcarbonspeed.com/Productinfo.asp?f=1327, and others), but I would like to run XX1 or X01 1x11 SRAM drivetrain.

The crank in both has options for BB30 bracket (30mm crankshaft) or GXP bracket (24mm stepped crankshaft). So there are 2 options how to fit it:

Directly pressed bearings into frame (for BB30 crank): http://www.rotorbike.com/products/mtb/bb89-bb92_98 or http://wheelsmfg.com/bottom-brackets/bb86-92/bb86-92-bottom-brackets/bb86-to-30mm-ceramic-hybrid-sealed-bearing.html. The downside is some spacers might be needed because the shaft lenghts migh not fit precisely (is this the case and true?).
GXP BB92 press-fit bearing cups (for GXP crank): http://www.tredz.co.uk/.SRAM-GXP-Team-Press-Fit-MTB-BB92-Bottom-Bracket_43299.htm. This should be less hack-ish solution and one I favour so far (but have zero experience with). Shimano BB92 brackets are not compatible with stepped SRAM crankshafts so I can't use one.

Which solution should I go with and which is better? Any experience and thoughts would be highly appreciated (I hate squeaking cranks!)

Other thing is I want to use 38T or even 40T front chainring in the 1x11 setup. Would there be enough room between the frame and the huge ring?
