Had a set of made-in-china carbon tubulars 10 speed that would work on my 11 speed Giant road.
Basically you need 1.8mm more depth on the hub so took a flat file to the nubs at the back of the hub. Measured with a caliper every few mins of work. . I could have used my lathe but this was quicker :). The filing mod took about 1/2 hour then a new 11 speed cassette torqued on and transfer to bike. Slight gear murmur but after some chain lube that went away.
20km ride, did some wheelies seems good. I shoulda taken some photos in the shop.

Also from China I've had a heck of a time with valve extensions. A whole mega-pack of them driving-me-nuts. As soon as I turn them down, PSSSSSSS the native valve leaks like crazy. Today I measured the presta nut and it's= 4mm. Then I took a <4mm drill into the extension and found the length inside was (way) too short. Drilled the extension innards with a 4.2mm drill and voila - it's fixed! Got a whole pack to do.
Next up I've got some really nice new tufo carbon 25mm tubulars tires to put on. Just a PS the Tufo carbons are great - I used them on my city bike & give them 5 stars for ride and quality. Good price a wiggle.com as well.
