Re: How to Add suspension
Google "bicycle swap meet" on the internet and find one in your area. They are normally in the fall and spring. Remove your rigid fork and take it to the swap meet with you. Steerer diameter, length (especially if it is a threaded fork), etc must match your frame.
Getting a fork that fits on the first try will save you more time to grade math tests.
