FYI. YOU can fit a wheelset with
700c ROAD tires (
e.g., 700x28-32) in 99% of the MTB frames/forks ...
When disc brakes had finally reached critical mass (
must have been about a dozen-or-so years ago), MAVIC introduced a "city" wheelset specifically so MTB riders could use their MTB more efficiently when not riding
off-the-road ...
'I' was subsequently motivated to lace a pair of Road rims to a pair of XT disc hubs
!!!

BUT WAIT!
YOU don't have to DIY ...
BECAUSE 29er bikes use 700c wheels.
So, YOU just need to EITHER buy an
off-the-peg wheelset OR you simply need to lace up a set of 700c rims onto your existing hubs (
or, have someone else build the wheelset for you).
- the price will vary from under $200 to your $1000 limit ...
IF your Hardrock does not have disc brakes and/or disc brake mounts then you can retrofit your bike with rim brakes intended for a Road bike ...
These are two of my
MTB frames which were designed to use 26" wheels which I re-fit with Road forks + 700c Road wheels + tires ...


- YOU do/(will) not need to change the fork on your Hardrock ... a Road fork makes the head tube angle steeper (closer to what you would find on a typical Road bike)
- and, trims some weight off the bike, too!
[*]YOU will have to measure the distance between the theoretical fender/(brake) mounting hole and the rim to use Road calipers
- the forward facing hole of the "fender" mounting hole was enlarged to accept a recessed brake nut
[*]Of course, you do NOT have to install Drop handlebars unless you want to.
- if THAT is the case, then opt for Campagnolo shifters (as pictured)
- SRAM & SHIMANO shifters may also require a wholesale exchange of the derailleurs
