I want to do some upgrading on my bike
https://www.specialized.com/us/en/bik...rdrock26#specs
this is what i have at the moment

I already changed handle bars, pedals, tires and seat post to make my bike lighter

I have finally saved up to buy some new wheels, i dont mind if its just one wheel or both,
But im looking for compatible wheels, since my cassette is a freewheel will it be harder to find light weight wheels? I dont know if they affect each other
Can anyone help me find light weight wheels that will fit on to my bike

I am an amateur on bikes, sorry if i didnt make any sense but if you could help i would be gratefull,
Ive been looking around for a while and i cant seem to find anything

The problem i have is that all the wheels i find are disk break only which makes it so much more difficult to find

Not sure how much you'll save per $?

You can get an 8/9 speed Free Hub rear wheel and add a 4.5mm spacer and use a 7 speed cassette.
The cassette can be had for around $20-25. The good part is you have a much stronger rear hub in regards to bending axles. You also have a little bit better selection of gear options, if you don't like the 14-34.

The most cost effective way to save a lot of weight is by going to a skinnier tire.

You shave alot more weight and spend less money if you ditched the suspension fork for a steel or CF rigid one. Decent steel fork would be like $50 or so,CF ones can be found for as little as $125. Just make sure it's suspension corrected.
