With that kinda mileage I suspect you have one of those super nice carbon fiber jobs. I think my bike was a...cannondale. I think. Whatever it was, it wasn't more than a few hundred dollars LOL.
I was in a bike shop and saw a carbon fiber bike once, if I remember correctly I or maybe the sales person picked it up with a single finger. I remember it was a very impressive machine. I also remember it was about 8 grand. Hopefully they have come down in price.
Yes, everything on the bike is carbon except the crank, derailleurs, cables, and seat rails.
I built the bike. It cost about 1800 to build. I frame, wheels, all came from China, but most of the frames for the name brand bikes come from China from the same factories. Mine just doesn't have a name.
It cracks me up, people comment on the bike, then ask what kind it is, then I tell them I built it.
Most all seem amazed when I tell them I built it. People have lost the simplest of mechanical skills, common sense, and the will to even try.
Yes, I have been riding and working on bikes since I was six (56 years) but it isn't rocket science! I couple screwdrivers, a couple wrenches, and a couple special tools, and the aforementioned skills and a six-year old could build a bike.
The bike is extremely light, till I add my bike bag (tubes, tools, emergency food, CO2/pump). I am also carrying a bag on the top tube in preparation for my big ride November 9th, it has a 20.1KmAh battery bank, DIY powder electrolyte mixes, my drugs, and ID's., then my 1 quart water bottle, and my JBL BT speaker, then my big fat butt, so all in all I add (not counting myself) approx. 15 pounds to a 15-16 pound bike. LOL
Oh, the wheels are also carbon, until you get used to them it like using a graphite fishing rod, very sensitive to the road, you feel everything.
My front wheel is 60 mm, and the rear is 88 mm, this is the depth of the rim.
I run very cheap Continental tires at 8 -12 dollars each, and cheap $2.50 cent tubes. LOL
Most people I know are running $70 tires and high dollar tubes. They are the GQ people. I checked specs on the high dollar Conti's (I used to run them) and besides price my cheap Conti's are as good if not better. The rolling resistance of the cheap Conti is between the two high dollar Conti's, mine do not have a puncture resistant layer. I had more flats with the higher priced tires. I got around the layer by adding my own layer inside the tire. I rarely get flats, one this year and it was catastrophic. Blew a hole in the side of the tire the size of a pencil. I walked home that day. I took the blown tire and cut some boots to add to my bike bag. The tire that blew (rear) had around 7K miles on it. It still had rubber on it, I guess the side walls got weak. Most people want to change their tires much sooner (around 2K-4K miles). I wanted to see how long I could use the tire.
I guess you found out more than needed. LOL Time to go ride (0430, should have been out a half hour ago). LOL
