I'm interested in converting my current Shimano Deore HB-M510 VIA-M (quick release) hubs, if feasible, into an axle based hub. (both are shown in pic) Overall I'm looking to swap wheelsets, from a front suspension fork onto a steel rigid fork. As you can see, original hub on steel fork has axle based in latching onto fork. Whereas my shimano deore is a qr, without axle.
So could hub be converted somehow or get new hub/wheelset? My rear wheelset though, does have axle.
Also if I wanted to add front disc brakes...which particular brands and brake models is a best recommend? Avid? Or other good value performing brand?
I also have a threaded headset (pic included) with flat handlebars on my steel bike, which I'm interested in having replaced with a threadless handlebar. Is height adjustment more versatile or easier with spacers? Also, does someone use adjustable stem (such as Specialized) on their bikes, is this an advisable useful upgrade in adjusting your reach? (to make riding more versatile, whether on road or trails)
