70mm to 100mm suspension fork

[Donski]

Recently got a 2006 giant upland see from a garage sale, was it pretty good condition, just changed the chain and tweaked the gears and brakes and all good.
Question is I want to upgrade the forks, they currently have a 70mm fork, would a 100mm fork work or should I find a better quality 80mm.

A 100mm fork will be OK for that frame, but you would not want to go any longer; geometry changes introduced by longer forks can increase the stress on the head tube junction, increasing the risk of failure.

The Upland is a very much entry level bike, and even a moderately decent suspension fork will cost a fair bit more than you paid for the bike.

Thanks, I wouldn't go any more than 100mm and considering the bike cost me $20 even cheap budget suspension will cost a lot more than the bike

Buy another bike? Maybe with the fork you want on it?

Thanks for the very informative answer warin

$20 is a bargain for what is a pretty basic, but decent bike. Sounds as though you would be overcapitalising by putting any form of decent fork on it. I'd be tempted to go the other way, rigid forks and run with a bit less pressure in the tyres.

As above, the $100-200 you'd spend on getting some very basic, or well used forks could probably buy you a 2nd hand higher spec model which already has decent forks on it if you want to ride it 'proper' off road. Might take some time to find a better bike, but when you do you could offset the price by flipping your upland for a profit.

If I were to buy a different bike would be the same situation just slightly more expensive base to begin with. Prefer to upgrade parts on this as I enjoy changing parts and it's a good way to learn more about bike machanics for when I can afford something decent in the future
