What are the compatibility considerations when upgrading to a Shimano Ultegra cassette for a 10-speed bike?
When upgrading to a Shimano Ultegra cassette for a 10-speed bike, it is important to consider compatibility with the existing drivetrain components such as the chain, derailleur, and shifters. Ensure that the new cassette is compatible with the chain and that the derailleur can accommodate the range of gears on the Ultegra cassette. Additionally, check if the shifters are compatible with the number of speeds on the new cassette. It is recommended to consult a professional bike mechanic for proper installation and adjustments to ensure smooth shifting performance.

How much is a 1973 10speed Schwinn sporter in good condition bicycle worth?
Bicycles rarely become valuable collectibles, so probably not a lot. Have a look for similar bikes on eBay and craigslist to find out what they are selling for.
Why cars do not have linearly increasing acceleration?
There are 2 main reasons, first is that with every up-shift of the transmission the mechanical advantage of the gearing lowers.( example: riding up hill on a 10speed bike in 1st gear vs.10th gear, 1st is easier.) The second reason is that wind resistance increases 4times when the speed doubles. (example: sticking your hand out the window of a car going 20mph vs. when the car is doing 100mph and you'll feel the difference.)Wind resistance is main limiting factor for top speed o most sports cars.
