stiffness...
if stiffness is your main concern then you got one of the worst cranks in 1st place!
as mentioned above don't go with titanium - get a steel axle but then i have to ask why you spent so much money in a lightweight crank when you ruin the weight advantage with a heavy BB....???? if you need the stiffest BB go with the Deore!! no kidding. as shown in the test below the 304g Deore square BB has the highest readings: 67,6N/mm. just remember that todays integrated xc-designs all have about 110-120 N/mm. even "old-style" XTR, the famous military grey crankset, only had 88,2 N/mm...and wasn't that the crank that all raved about how super stiff it was
you could have gotten away much cheaper with let's say some Race Face Next LPs and a nice Titanium BB with probably lower weight and better stiffness on top...
BUT my opinion about all those stiffness numbers is different anyway. i have never felt any power loss nor has never been a test made where they show any increase in power with stiffer cranks. what are all those overhyped intergrated cranksets with more than double the stiffness of old style square setups doing better? they "feel" stiffer? chainrings rub less on the front derailleurs? oh , very cool
just remind you that until 1-2 year ago half the Pro-Peloton in the roadie scene was using Campagnolo cranks with square BBs...and some of the best sprinters won hundreds of races sprinting with over 1000 watts on "flexy" square BBs...
anyway - below are some stiffness numbers which might be of interest for you...enjoy!
by the way: Stiffness readings are shown in N/mm
