MTB double cranksets

What do we know about them

Im in the market for a double as ive just bought some 10spd shifters that are 2x10 so i need to change the whole set up to a generic 2 ring
Reasons are long complex and rather sad but needless to say ive got to change the lot because of my current crank is 110mm bcd and i need the smaller outer of 38-40t to fit. Its way too much hassle to find new rings,hope i can get the front mech dialed in etc etc. Best just start again and do it corrrectly

Im adding 10spd XX shifters and as theyre rather nice would like some nice bits to go along with them
Cranks/BB and hopefully an XX front mech but failing that an XO.

I obviously need a 10 spd block so crc is about the best place for cheaper and was considering this one.

And for the cranks, along this line

These were very nice also and a great price too. Theyre going on a mirror polished ti frame so i though they would blend in really well. The only niggle i have about these are from reviews that said the megaexo can develop lateral play.

Any one know about any of the following ? Or know of any good double crank deals going about.

Have you tried any of the German sites? My cassette and chain was a fair bit cheaper from Rosé than from CRC.

I've not heard great things about the mega exo BB's either. The Sram cranks are nice, but the cranks rings are specific by the looks of it.

All of that stuff you've specified looks really nice though.
