|So I am contemplated the recent surgery I had to the head of my femur(the bone that goes into the hip), and I am trying to come up with positive things as a result. After thinking about things like now I can concentrate on good form because my leg hurts when I let it bow out during a ride, I don't have to worry about avoiding the big hills because I can't do them yet, the nurses were very cute....then it dawned on me. I have 4 titanium screws in my hip area to help support the bone that was reconstructed! That means I have dropped some 30-40 grams by having titanium in there instead of bone(I am missing more than half of the bone). Just think what that means....instead of weighing 200 lbs. I now weigh 199.90 lbs. That weight savings is going to add at least 1-2 miles per hour to my average speed. And when I am able to do hills again, I'll be able to fly up them like nothing. All this at a cost to my insurance of just under $25,000.00. I have to say it's well worth it to drop that .1 lb.|

|the friend of mine had srews made in Swizaland (hip recostraction after rack), when it came to take 'em out turned out hospital he went to had no compatible screwdriver. Now imagine, he is laying in surgery room under anestesia and guys're running and trying to find something to take 'em out.
PS Ti screws are only good for 4-6g of weight saving, so don't count on beating me on next climb ;)

|I've got 7 stainless steel screws in my left knee, and I've never looked back. The way those pins reveberate when I bang my knee - let's just say nothing else feels quite the same ;-)|

|I am pretty sure mine are stainless steel as well(I didn't ask at the time). I just thought I would have a little fun with those that are convinced that titanium is the answer to making bikes lighter and increasing performance.
It's nice to tell people you have a couple screws loose and mean it literally. :)

|I sustained a Tib/Fib fracture while playing soccer a few years ago. Now I have a rod inside my Tibia (shin bone). It goes from my knee to ankle. I was disappointed when doc said it was S. steel and not Ti or other high zoot metal.|

|....on it's own, Titanium is real heavy!!! It's really reall strong though, so they can use less of it. It's the strength to weight ratio that matters. They use Ti because it doesnt react with much, so it's safe to use inside the human body. And also, it's not Stainless Steel they use, it's Surgical Steel, which is much harder than regular stainless. Regular stainless is pretty mushy, so it's not really good for support. I think Ti is somewhere around 60 times the weight of Aluminium for the same volume... So technically, you gained weight, cuz bone is much lighter!!!!
This takes nothing away from the fact that you got Ti in your body though!!! Get better soon! and enjoy the nurses!!

|But Ti has tendency to shear on riders over 165 lbs. Be careful on the climbs, spin don't hammer or you may break your leg like I've done with a Ti BB (came on the bike)
Get well and have fun ya crazy freaks, I may be getting some hardware in my shoulder soon. This cheered me up.

|Ti weight is ~1.5 x Alum. for equal volume.
