Here's the current state of my "Frankenbike" commuter. Sorry for the (lack of) quality, my phone's camera sucks.





If anyone's interested, here are the specs (and the reason why I call it a Frankenbike):

• Frame: Unknown, given to me by a friend 5+ years ago. Probably a Univega Alpina from the late '90s, but I'm not sure. 18", steel.
• Fork: Mongoose rigid from an IBOC I got for free. Spray painted with rubberized underbody coating.
• Stem: Mongoose 90mm form the same IBOC
• Handlebar: Al, 560 mm, also from said IBOC
• Headset: Generic, 1-1/8", threaded, cup-and-cone
• Bottom bracket: Shimano something, square taper, from a 2008 Specialized Hardrock XC
• Crankset: Shimano Altus M311 triple (24-34-44), also from the Hardrock.
• Pedals: Cheap Al/steel platforms
• Cassette: Shimano something, 7-speed, 11-28 teeth, from the IBOC
• Front derailer: Shimano Tourney something from my parts drawer
• Rear derailer: Shimano SLX M670, Dyna-Sys Shadow, 10-speed. Cable routing changed to somewhat compensate for the different pitch of the 7-speed cassette.
• Shifters: Shimano SLX M670 with gear indicators (they weren't removable until the next model), 3×10. Taken from my MTB (together with the RD) after that one got upgraded to 1×11.
• Chain: Shimano HG40. 8-speed
• Wheels: Double-wall rims, steel spokes, Quando hubs. Got them in exchange for a pair of clipless pedals I had lying around. Rear hub converted from a solid axle to a QR. Ghetto tubeless conversion using split 20" tubes. Caffélatex sealant.
• Tires: CST Control Viva Eco. 3/10 - heavy as hell (IIRC well over 800 grams each) and very little grip in the wet. 40 mm wide.
• Brakes and levers: Avid Single Digit, bought used for 400 CZK (<17 USD)
• Seatpost: Force Al, 25.8/400 mm, 20 (?) mm offset
• Saddle: Author/Selle San Marco Arami from a scrapped bike

Accessories:

• Fenders: B'Twin 100 (?) from Decathlon
• Rear rack: Force Disc, Al, 25-kg capacity, disc-compatible (obviously).
• Front light: Polaris "7 LUX"
• Rear light: Crivit something (from a set, the front light died), USB rechargeable, from Lidl
• Saddle bag: Crivit, the top secured with a large zip tie (which I've found far more reliable than the original detachable clamp). Inside:
  • CO2 pump, patches, and tire levers: Weldtite JetValve saddle bag set
  • Multitool: From the original set
  • Chain tool: A basic $1 Chinese one + a few generic master links
  • Tubeless repair kit: From a random automotive set (plugs and insertion tool only)
• Pannier: Random "Bike Upgrade" that Tesco had on sale for ~120 CZK (~5 USD). Claims to be water resistant without any extra cover and, to my surprise, did indeed keep everything inside dry when tested. I have two of the but haven't needed the other one yet. Inside it I keep a mini pump, a small bottle of sealant, and a cable lock.

According to my quick calculations, I spent less than 4500 CZK (190 USD) on all of the above.
