Shimano Hollowtech 2 Arms: Road vs. Mountain - Same but Different

"Test all things; hold fast to what is good" - 1Thessalonians 5:21

Non-drive or left crankarms are both basically interchangeable between road and mountain.
Differences in spindle wall thicknesses between say a 6600 triple and XTR are different. The XTR is thinner. I assume the Dura Ace is also equally thinner/lighter than the equivalent Ultegra.
But I also discovered that the XTR arm bows out more from the spindle to the pedal, therefore, the pedal is more outboard/farther from the longitudinal/fore-aft center line of the BB!
So, there I was thinkin I could slap a lighter XTR arm instead of the existing 105...I could but I'd lose significant pedaling clearance so I kept the 105 on bc it wasnt worth it...oh well, I guess I gotta get a Dura Ace arm then!

Bicycling / Cycling Efficiency / Performance ! :O Thank GOD

Hmmm what else shall I write about as an adult Christian-Chinese-Canadian-Torontonian 4-season cyclist... How God has given me this opp! Yes! He rocks! Therefore we rock! "Because I (Jesus) live, you will also live" John 14.19 :O Woah.  That's BIG.  Only God can say that and back it up, eh? ;)  Love Him.

Thank you Loooord for bikes.  Bikes being by FAR the most efficient means of transportation. Period. I am talking worlds more than ANY other vehicle incl. cars, jets. even any animals.

This was proven and documented by Richard Weber at some university (I recall Duke or somewhere on the East coast of U.S.).  Google it.  Absolutely awesome. No wonder there is that special something that happens when you bike...yeah, it's called YOU workin in perfect harmony with a MACHINE to acheive the most efficient thing in existence!

http://en.wikipedia.org/wiki/Bicycle_performance :

"A bicycle's performance, in both biological and mechanical terms, is extraordinarily efficient. In terms of the amount of energy a person must expend to travel a given distance, investigators have calculated it to be the most efficient self-powered means of transportation.^[1] From a mechanical viewpoint, up to 99% of the energy delivered by the rider into the pedals is transmitted to the wheels"

BOOYAH

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?

Most Comfortable Bicycle Bike Seat Saddle

For a skinny 130 - 140lb., 30+yr.-old, Asian male. Tried 10 relevant saddles before settling on these:

1. WTB Speed She

2. WTB Pure V

3. Try any WTB saddles!

No, I do not work for WTB. But, I am a year-round cyclist in Toronto and have worked for bike shops since 2000 and am currntly gainfully employed as the service manager at a busy downtown bicycle shop.

BROOKS? Havent tried yet. But, I will, come spring with the classic B17. Currently on the WTB Speed She...if only they'd make it lighter and longer! :I But, alas, yes, it is a "women's" saddle :P...but my goodness is it ever comfortable!

Thank God for NORCO who is the big distributor of WTB saddles to all your local independent bicycle shops in Canada. But, of course, u cn get a WTB product anywhere in the world.  So get one and sit on it!

Ride On!
