No. There are a few options with regards to fit and suitability for your bike. Forks can either have a tapered (1 1/8" to 1.5") or non-tapered (1 1/8") steerer. The rake of the fork can also differ, this is the amount of forward 'offset' from an imaginary straight line through the steerer tube. If you are replacing a fork it is important to match the existing forks rake and headset type. Most forks are carbon fibre, most have a carbon fibre steerer tube and some have an aluminium one.

Forks for disc brake road and gravel bikes also feature the disc mounting point for flat-mount or post mount disc calipers. They also feature internal or external hose routing and many have 'thru axle' fitting for the front wheel, some have quick release drop outs for older bikes.

Cyclocross (CX) and touring bikes which have cantilever brakes require a fork with cantilever brake mounting points.

This is dependent on a number of factors. How much use / abuse has the bike had? What conditions is it usually ridden in? Has the bike been crashed? How heavy or strong is the rider? How good is the rider at avoiding potholes in the road? The list of potential frame life inhibitors is extensive. Take care of your new frameset and it should last a very long time.

We are living in the information era, where experience, skills and know-how are just a mouse click away. So with the right tools and knowledge, it is relatively easy for someone who does their own bike maintenance to build a bike, especially if you have a fair amount of experience with bike maintenance. However, relatively new riders or those who usually drop their bike in at the mechanics for a service, might prefer to get a mechanic to do their build.

It is usually cheaper to buy a full bike because the manufacturer has the economies of scale purchasing components, and they can usually do this more cost effectively than the individual. However! If you want a specific build that the manufacturer doesn’t offer or if you want to use your existing wheels or components you have sitting collecting dust in the garage, it may well be cheaper to build your own.
