Whats the most efficient way to replace a broken quick release lever on a mountain bike, considering Im dealing with a thru-axle system and not a traditional QR setup? Ive seen some tutorials online, but they all seem to assume a certain level of familiarity with the inner workings of the bike, which I dont possess.
Are there any specific tools or materials Id need to have on hand before attempting the replacement, or can I get by with the basics like Allen wrenches and pliers? Whats the most common mistake people make when trying to replace a QR lever, and how can I avoid it?
Is it possible to upgrade to a more reliable QR system while Im at it, or would that require a complete overhaul of my bikes wheel and axle setup? What are some key signs or symptoms I should look out for to determine if the QR lever is the only problem, or if there are other issues lurking beneath the surface?
