This year marks my 16th year of cycling life, having started out with an XC hardtail mountain bike,
and currently, I own a total of 4 bikes: hardcore-hardtail, all-mountain, enduro, freeride, and aero road bike,
and the bikes I've gone through over that time include BMX, gravel, trail bikes, etc...
There may be differences in the items each person carries, but I use a bag that mounts under the saddle,
and I carry the items shown in the photo above of the POST CARRY product.
TPU Tube: The downside of existing products is that the valve stem is plastic so it cracks easily, and the unfortunate event of the valve core slipping out occurs.
Naturally the valve core is metal, and since the valve stem that holds the core is plastic, there's no way it could be durable.
On top of that, there were also troublesome problems where the joint cracked at the coupling area connecting the tube body and the valve stem, so I struggled more than once or twice
or twice. High-priced products were the same too, and that was one of the reasons I stopped using TPU tubes. Even now I carry regular butyl tubes
on my mountain bike. They're old but reliable.
In any case, I chose a tube I can use with confidence thanks to the change of the valve stem material and the strengthened joint durability, which address the two problems that off-the-shelf products had.
PB SWISS: It's a wrench set that can be used in the PB470 bit socket type. Usually people use folding tools a lot, and there's no particular difficulty using them on ordinary bikes including mountain bikes,
but there are cases where they don't quite suit road bikes.
For example, if it's a product that uses a hidden clamp type seatpost, among folding tools the ones with a short neck are useless.
That's because the tool doesn't engage with the bolt head. On top of that, because of the wide tool surface area it touches the frame, so the tool can't rotate.
So I choose tools for mountain bikes and tools for road bikes separately.
When I rode the Cannondale, a folding tool was enough, but this time after switching to the Cervelo, the seatpost fixing wedge
is in a form that goes somewhat deep into the seat tube, so the SILCA product had a short neck and didn't fit. So I changed to the PB Swiss product.
It's light in weight, and includes a 2/2.5/3/4/5/6 -,+ screwdriver, a T25 spec bit, and even two tire levers, and to keep the bits from being lost
it's made with magnets on both directions of the connector.
One unfortunate thing is that the price seems to have risen by more than 1.5 times compared to before.
C-TO-C cable and power bank — these days most electronic devices are being unified to the C-TYPE standard.
Headlights, taillights, action cams, smartphones, etc., but if the battery dies it's meaningless. In a place like Korea where the infrastructure is well established and there's a convenience store wherever you go, when you're not a randonneur or tourer who rides while being completely self-sufficient, do you really need to carry around even a cable? you might think, but
By my standard of always 'prepare for the worst,' since I once had quite a hard time when my smartphone battery went right up to the brink of dying, I always keep the optimal battery state in mind. It's a USB-c type bidirectional cable, 15cm long, with a terminal protection cap attached.
The wire is finished in a thick fabric material so the durability is trustworthy, and there's a protection cap fitted so that foreign matter doesn't get into the terminal part or the pins don't bend, which I like. Originally there's a loop that connects the caps together, but I don't need it when storing it in the saddle bag, so I removed it.
(The power bank I'm using is a product in an AA battery size with a C-type port.)
Co2: It's a Pitis inflator and two 16g canisters. I was going to carry a 25g, but in line with my master's teaching that you should always have a spare and backup in case of failure,
I carry two 16g ones. Actually I received an electric pump as a gift, but it's bulky and noisy so I don't use it much.
For now, the list of items I carry is as above..... the portable items for riding are as above, and if I just carry the mini chain tool that's currently being shipped, I'll be prepared for chain snapping and tire punctures, the most common accidents that can occur while riding.
You might think it'd be better to just use a tool can and make use of the ample storage space, but
personally I absolutely have to use two water bottles, so the tool can is not under consideration.
For reference, I once rode with a Tour de France rider, and
that rider too, when riding, carried a small regular hand pump in the back pocket of his jersey.
