Hey, I have a Specialized Hard Rock Sport Disc 29er (2010) and I am looking for a new fork. What would be a good upgrade for the bike? What things do I need to look for compatibility wise other than the wheel size. I want to go either air or hydraulic, and this is for moderate off road and mtb trail riding. Lockout would also be nice for getting to and from the trail. I have been told the stock forks are crap, and I think this will be the first upgrade that I will do.

What is the current fork on the bike?

SR Suntour SF10-NVX-MLO-700C-80, 80mm, 1pc. alloy lower, 28mm Hi-Ten stanchions, coil/mcu spring w/ preload adj., size-specific spring rates, spring assisted seals, disc only

get something with air for sure....

Yea I know I either want to go air or hydraulic. I just need to find out what forks are compatible, and does anyone know of a specific fork that would be good for this bike?

Do you mean air or coil?

Check steerer tube size (1-1/8, 1.5, or tapered...you may be able to put in a reducer headset if your headtube is too large), check to see what kind of front hub you have unless you want to buy a new front wheel, make sure the steerer tube hasn't been cut too short, check the axle to crown measurement to see if it's comparable to your bike or that it'll change the geometry in a way you want.

THANK YOU!!!!! And on the air or coil, I thought there were 3 types of fork, Coil/spring, air, and fluid/hydraulic going from worst to best in that order.


So now the question is, anyone have a suggestion on a fork (brands to even a specific)?

Coil isn't necessarily worse than air. It's heavier, and it's not as infinitely adjustable as air because there are only certain weight coils, but it offers more linear travel, and some people like it because they say it's smoother.
