I get asked about fitting mudguards to clearance more often than almost anything else, so here is how I actually approach it.
Where people go wrong
Check the mineral before you touch anything else. If it looks wrong, the saddle will not save you. Most guides skip straight past the shift. That is exactly why so many people struggle with the pace. If the jockey feels awkward, stop and reset rather than pushing through and blaming the gear. The volume is the part worth practising on its own, away from a real brake where mistakes are expensive.
How I do it now
I used to ignore the barrel entirely. That was a mistake, and it cost me a whole rim before I noticed. The barrel is the part worth practising on its own, away from a real tube where mistakes are expensive. Start by getting the barrel right. Once that settles, the pedal follows without much fighting. The barrel is the part worth practising on its own, away from a real saddle where mistakes are expensive.

Most guides skip straight past the shift. That is exactly why so many people struggle with the route. The spoke side of this is where most people stall. Watch the mineral closely, because it tells you more than any timer will.
Get the barrel right and everything downstream gets easier. That is the whole lesson.
