Rigid versus Suspension? Black versus White? Whiskey versus Bourbon? There’s no right or wrong, but let’s be clear suspension = comfort.
We’ll always recommend a good saddle, with some kind of suspension be it in the saddle or in a stem suspension. Front fork suspension? Absolutely, your hands and shoulders will thank you.
Thinking of going off-road? Then front suspension is a must. For those looking to go do some serious off road, rear suspension will keep that tire more in contact with the terrain for that all essential grip.
A good alternative is a set of fat tires. This will be more than sufficient to soak up bumps, potholes and kerbs is most urban usage cases. 😉
