Old thread but still evergreen, so I'll put in my two cents...
I have always used toe clips and straps and continue to do so, largely because I've invested in SunTour Superbe/Superbe Pro pedals for each of my bicycles, and they have yet to wear out! They use a well-shielded combination of deep-groove Conrad cartridge bearings and roller bearings and they just go and on. The one pair of XC Pro variants even have the WTB-licensed GreaseGuard injection system that pushes out contaminants as fresh grease is injected; ideal for really poor conditions. Between the tandem and the singles, I'd have to rebuy a number of pedals, so I plan to with these till they die.
Decades ago, I managed to buy out the remaining stock of old size 45 Detto Pietro Article 74 1- and 2-bolt cleated cycling shoes (leather with nylon soles and cleats) from a failed bike shop and they are a good match for the pedals, so I should be set for awhile. The first pair lasted for 100,000 miles before I reglued the toes and heels to the soles and delegated them exclusively for use on muddy/rainy day rides. I carry a spare set of shoes for walking and off-bike use while on-tour (a pair of nylon mesh Merrell Breeze clogs I can kick on and off with no hands needed when I crawl in and out of my tent while cyclo-camping).
I really have nothing to compare my present setup to; they have always worked well for me. That said, I'd sure be willing to try a set of clipless pedals and shoes if I could find a set in leather to fit my narrow feet. I can see dedicating my expedition bike (the Sherpa) to a clipless setup while keeping all the others as quill-and-clips-and-straps.
Are there any clipless pedals -- I think I'm beginning to prefer the SPD format for walkability -- that have shielded cartridge bearings and similar longevity to my SunTour Superbe/XC Pro quill pedals? Any good leather shoes you might recommend for SPD use? Thanks in advance!
Best to all,
Dan.
