On my first tour a muddy road clogged my front fender. Some digging then I got mad and kicked the fender. It broke and was tied with a shoelace the next 2 months.
I've done dozens of kludges for 50 years. Made stuff out of metal mart and road kill metal.
My 1973 Raleigh had hollow levers, so once I just threaded thru the cable to use the cutoff different end. Frayed way sooner doing this. LOL
That bike had a rusty tin paint can on my top tube to hold the spare tube and pryers.
One light mount was a wooden ladder brace later nickel plated, the other was a 18" dishwasher door hinge, that I took all apart when I was doing renos.
My ear muffs was from a 1970s spring, a coat hanger, the furry cover was off a new one with useless plastic hoop, nail head rivets and a old wool sock liner.
Nail rivets in some of my brake levers.
My tour bike tool chest was a thermos covered in CF, with the hanger that was a handle picked out of a pile of bar-b-que that fell off a moving truck.
The rack mount on my CCM was 1/4" plate alu found on a highway.
My front rim brakes on 3 bikes would never stay straight, so I hooked them with copper wire and mattress springs off old seats. LOL
Mirror mounts used to be levers.
SJS sent me a wrong narrow spring rail set 5 years ago for my Brooks Flyer, so I spent weeks cutting, filing and drilling 1 x 1/2" alu bars and two 8 mm bolts to take the place of the springs. Used it several months on my Simcoe bike.
My Rohloff shifter knob for 10 years has a rubber hat cover found in dad's garage.
DIY wrap around kick stand that's a big nuisance to use.
My down tube bottle holders were from friction shifter holders. Finally gone now.
My dad had tires inside tires and tubes with 15 patches. It went flat and I cut it up. LOL.
Plus all the CF stuff on all 3 bikes.
My CCM now has an awesome DIY metal bracket to hold my shift cable stop to my indicator chain.
