Sram Red22 crankset has a normal lenght spindle :http://img.artscyclery.com/big/SRRECB3-4.jpg
Sram Force22 and CX1 both have a long BB30 spindle:http://i1215.photobucket.com/albums/cc5 ... 1b4dcb.jpg
and Sram Red22 with Quarq has a long spindle :http://img.artscyclery.com/big/SRRQBB3-6.jpg
I want to know if the long spindle BB30 can fit a BB86 if anyone know eventually
Answer to your question is yes...but you need to revise your description above because, your reference of Sram Red22 crank as being 'normal' length means nothing.
Sram Red22 without Quarz has what would be called conventional BB30/PF30 aka short spindle length. Sram Red 22 with short spindle will not fit a BB86 because it is designed for 68mm wide shell with BB30 bearings inside the shell and BB86 is the equivalent of a std 68mm BB with bearings 'external' to the shell in terms of width spacing.
I believe grover above was the most succinct:Force 22 BB30 has a spindle length long enough for BSA threaded/BB86. Red 22 BB30 does not.
The reason why Sram does this which may be considered confusing to some is a matter of weight. Force is their second tier crank they make with a longer spindle to fit a vast variety of BB's from BSA to wider shell BB86 and BB90 aka Trek. It can also be used on more ubiquitous BB30 and PF30 with a 11mm spacer on the drive side to take up the longer spindle length that makes the Force 22 a universal fit.
By contrast the Red22 BB39/PF30 cranks is a lighter shorter spindle crank that is more of a compromise toward performance and weight. Their 30mm variant of the Red only fits std width BB shells for BB30 and PF30.
Hope that helps. Sram does a bit different than both Shimano and Campy whose highest end crank models are both long spindle 24mm and 25mm spindle diameter respectively...but Campy does offer a long spindle 30mm crank that is not unlike Force 22 and its called the OverTorque also similar to Rotor 3D+ which is also a 'jack of all trades' long spindle 30mm crank that can fit both narrow BSA and BB/PF30 with spacers and wider shell BB's growing in popularity.
Here is a clear as mud...not that bad
Sram published BB compatitiblity chart for their cranks...note it is three pages and covers Red, Force and S9xx :https://sram-cdn-pull-zone-gsdesign.net ... onents.pdf
I am reminded of the poet Marmion:Oh, what a tangled web we weave
When first we practise to deceive
It isn't really just like that but nobody in the bike industry would question that it is a tangled web or in modern parlance a cluster-f##k.
