A seat bag occupies a curious space within the life of a cyclist. It’s usefulness is in direct proportion to its hideousness. The bigger they are, the less attractive they are. You want one that will carry all the items necessary to get you out of a jam, but no one wants the cycling equivalent of an expedition backpack hanging off their saddle, unless maybe they are actually on an expedition.
If that’s not enough to make you wrestle with what seat bag will best suit your needs, then consider the way that little velcro strap that goes around the seatpost has a habit if just brushing the inside of prized bib shorts. Those first couple of pulls multiply until you have the equivalent of leg fleece. Eventually the leg fleece gives way to a hole. Back when I raced and got several new pair of cheap bibs every season, it wasn’t a big deal. These days, with good bibs running upward of $150, that first pull is a tantrum inducing event.
This past spring I ran across the Micro Caddy from Lezyne. It comes in two sizes, small and medium. The small, shown above, is just big enough to hold a tube, a CO2 cartridge and adapter, plus a mini tool in the small pocket on the under side of the bag. It’s the sort of bag useful for the morning group ride. The medium is But that’s not why I fell in love with it. The Micro Caddy uses to neoprene straps that fit around the seat rails—nothing wraps around the seatpost. It’ll never put a pull in your prized bibs. The medium has the same circumference, but just runs a bit longer. You can fit a second tube in it. Because the straps are made from neoprene, they stretch. Should you suffer a flat out on the road, the straps will compress the bag to keep any leftovers in it from clinking around and making you think your cassette locking is loose (been there, wondered that).
Whether you go for the small ($20) or the slightly longer medium ($25), it’s a foolproof way to take better care of something that matters far more than what hangs off your saddle—your bibs.
