Gear Whore #1
Some kind of wonky. Sorry for the double post.
Saw the grandson today. 8 pounds 2 ounces when born. A gentle baby, not moody, or picky, fussy, or temperamental like my grand daughter. Just a plain happy boy.
When I asked the grand daughter if she thinks he looks like her, crickets… LOL.
Anyways I was expecting a response. Lots of stuff going on inside an eight year old’s head at this time.
So I kinda figured that I could use the 11-34T XTR for a 9 speed, but not use the 11 tooth to keep the 8-speed shifters. Pretty much the spacing and the pull on the derailleur cable is the same for 8 and 9 speed. This also allows me to still fit within the max cap design of the derailleur so I can use the existing 53/39 double chainrings for a wide range of gears. Kinda dumb, but also kinda smart. Also a bit strange and odd, but to me that is cool.
Very out of the box, perhaps a bit crazy, but I get the low gears I require, and I utilize what I have. I can live without a 134.91 inch gear for a high gear, but having a low gear that extends down to a 32.12 inch gear is mucho useful. Know that one revolution of the cranks moves the bike 134.91 inches as far as pure distance goes to understand the gear I am loosing. Kinda nice to crank on a downhill, but a rather tall gear to push otherwise.
Bonus is that it uses what I already own, and I don’t have to buy anything.
I also get to keep a medium cage 11-speed XTR rear derailleur as a spare as intended. BTW right hand XTR SR-M9000 trigger shifters are back ordered everywhere. This is what I hate about pandemic shortages.
Don’t know if I’ll ever need or use all the Dura-Ace cassettes I acquired, but they were bought on the cheap years ago, and at this point they are like holding gold coins that will only appreciate in value. Already I can kinda doubled my money. I think I’ll hold onto them as a hard asset.
So another research experiment will be ongoing on this road bike. This bike weighs 18 1/2 pounds with mucho heavy training wheels that are 16 straight gauge spokes with heavy brass nipples on not lightweight rims.
Know that I have a set of racing wheels that are made with double butted spokes, alloy nipples, and light weight rims. My guess is that with my racing wheels a sub 16 pound bike. I also figure that when I upgrade to XTR trigger shifters I’ll likely unload about a pound by getting rid of the first generation XTR shifter levers. Know that this would require buying new brake levers north of $150.00, but that is cheap to save about a pound in weight.
The first generation XTR is so overbuilt. They used sealed bearings which is crazy in a shifter. Full metal construction. Very pretty, but heavy.
Not sure if my long cage derailleur can handle the 11 tooth with a 53/39 spread. I could lower the 53 to a 52, but that likely would not get me there, but a changing the 39 to a 42 brings me into the max cap range where it will work, but I loose some of my low gearing. Oh-well, still kinda low…
Peddling a big gear with a tiny 11 tooth on the rear is great for exploiting gravity and momentum that can be gains on the downhills to get one into terminal velocity about 50 MPH on a road bike.
BTW 50 MPH on a bike is kinda fast. A lot can go wrong. Did you know that at 55 MPH you are traveling 80 feet a second?
Do you see all the math and physics involved in cycling? To me mountain biking is studying and doing physics in real time.
Did you know that about 50 MPH the wind causes enough turbulence to make your eyes tear to inhibit your vision. It is a heightened reality that includes a bit of tunnel vision.
