HOW?
HIVE!
the HIVE by e*thirteen has been producing a 30mm AL spindle crankset that fits English threaded BB (bottom bracket) shells in both 68 and 73mm in widths. Yup, you heard it right, you can safely install a cutting edge superlight N stiff 30mm aluminum integrated spindle crankset onto any old frame! Like those old steel 70's "10-speed" bikes you find in decrepid, rotting public junkyards...or Bike Pirates - same thing, right? :D Just kidding Geoffy B (Bike Pirates founder)!
Albeit, currently that I know of, the only 30mm diameter aluminum spindle crankset available that wld work here is e thirteen's own fifteen G cranksets which r an MTB 4 bolt 104 bcd design. Maybe a BB30 triple? It's all about the BB shell+bearing width in relation to the crank's integrated spindle length; spindle must be the right length/long enough/longer than a typical road, double chainring crankset's BB30 spindle.
This (useful?) technical/mechanical discovery brought to you by BIKEFX by Dex....or just, Dex...that's my name and cycling's my game!
Ride On!

11 Speed Cross Compatibilities: Shimano Dura Ace 9000, Sram XX1, Campagnolo, Alfine.
I will be trying these combos, esp. 9000 shifters with Srams XX1 11speed 10-42 cassette and Shimano or compatible rear derailleur. Why? Because its bloody desirable as heaven thats why!!! As my Polish boss, Radek frm Wheels of Bloor the largest Cervelo dealer inthe world in Toronto would say: "KOURVA MACH! R u kidding me??!"
Srams widEST 10-42 range superlight external 11spd cassette/gearing now allows a justified use of just 1 chainring thus no front shifting/shiftr/derailleur/2nd chainrng/clearances/xtra weight/cabling etc needed at all! It wld b by nature and simplicity, Lighter, Easier, Smoother, and potentially a stiffer frame due to more room for frame material in tht area.
LET THE TESTING BEGIN AND VIDEOS BEGIN!.... STAY TUNED TO BIKEFX FOR UPDATES.
My Shimano rep didnt evennknow if we cld use non 9000 rd with 9000 shifters :P. Shame! I bet you can. We must in order to work w 42t cog we need an mtb rd with 42t compatibility. So far, Sram's XX1 is the only one, officially. Unofficially? Any rd with a max. cog tooth of close to 42 will work...just not as smoothly as the XX1's - RD's pulley wheel with less than 42t max may touch the 42t cassette cog in that 42t gear only. That'd be the biggest issue. Next would be tht its shifting path may not match the 9-42 cassette shape but, that is likely a non-issue.
Crap ths is gonna b expen$ive...900$ shiftrs...who knws how much xx1 cass gona cost... Gotta borrow... ;)
STAY TUNED TO BIKEFX FOR THE LATEST TECHNICAL/MECHANICAL STUFF.
NB An 11+ speed internally geared hub is also worth noting here for non-racers aka, 'US" the people, the rest of the millions of people on earth that bike daily for fun up to multiple times a day all year round for transportation etc. ;)
WHY? Forgetting the additional 100's of grams of weight in the rear and limits against super light wheel choices because only many metal spokes can be built with these IGH hubs....ugh....you DO get a smoother and thus longer lasting chain, super smooth and ultra wide gearing all with little to no maintenance compared to regular/monthly maintenance with external gears.
***My greatest apologies. My connection did not come through with providing the XX1 parts for testing, therefore, cant test! Don't we hate it when people don't keep their word folks?
