Brompton Bike rack hooks for thin rubber and thin tubes.

I made compact enough but sturdy hooks for my bike. Will fit another bikes/racks with similar thin tubes (8-13mm). Rubber itself is also pretty thin, diameter about 4mm. The rack is from Ali https://www.aliexpress.com/item/1005002929652010.html Pretty cheap, light and I like that it connects to easy wheels bolts, not to brake mounts like most of brompton specific racks.
