In short, what kind of straps are good for use inside a rinkō-bukuro?
The paint quality of my frame is terrible. As an example, here’s what I see on the seatstays after I’ve removed the saddlebag:
(Sorry about the dirt. There are plenty of other paint scrapes, many of which I can attribute to packing, but they look pretty much the same and they’re harder to photograph.)
My bike bag is big and crude. Remove the front wheel, lay the remaining 3/4 of the bike on its side, strap the front wheel onto the frame, insert into bag, zip up: done.
Until recently, I’ve used the straps that came with the bag. They’re perversely long, which probably should have warned me that Tiogra (?) didn’t put much thought into their selection. Anyway, they’re of the narrower type shown here (with a 10 yen coin to give a sense of scale):
So, I’ve used three or four of these to tie the rim to the seat cluster, the top tube, maybe the handlebar. Tightly!
When I come to extract the bike from its body bag, they’re all more or less loose. This of course means that the wheel has been able to flop around: scrape scrape.
I replaced the narrow straps with the wider ones. This has made no difference.
Should I be using velcro tape, perhaps? (And if so, where can one find this? A couple of years ago, I searched for it but couldn’t find it.) Or something else?
