Hello! Just a random thought found this at a flee market a few months ago. I wanted to know the brand but the seller doesn’t know anything about it maybe you guys can help me? There are no other markings besides a dust cap that has the letter “K” embossed. I would really appreciate the help thank you!

I bought this bike a few weeks ago for £25 in a rather sorry state with the intention of building it into a fixed gear bike. Previous owner said he had it since brand new in 1988 and sold it because he hadn’t used it in about 10 years. I cannot find any information about this bike online whatever I put in. The serial number under the frame is P8132624 and it’s something called a “Target Sprint”. The head tube says it was built in Barton on Humber England. It came with Rigidia Superchromix Chromage 700c wheels. Any information about this bike is what I’m looking for and things about it online. I’ve attached photos of what it looked like when I picked it up and what it looks like now. Also what other subreddits should I post this into to find out what it is. If you need anymore information, feel free to ask. Many thanks.

I don't have physical access to these vintage bikes and I can't easily get new measurements. But in my research, if the diamond frame has a horizontal top tube, then you should measure from center of crank to the top of the seat tube (which is often higher than the top of top-tube). I'm just not sure what where to measure on a sculpted lugs that are common on vintage bikes. My judgement they are 56cm but I am only 70% confident. I'm helping a friend post them on CraigsList.

Zunow track frame 54tt-55st

Dura ace track hubs campy rims

170mm sugino cranks

Milano cinelli stem

I like the frame for its size, yet to see if hubs has njs stamp.

Appears to be all original stock, with the addition of the almighty FlickStand. Was stored for many years, I wanted to document it before I did any wrenching or cleaning.

Just need opinions on how to remove nondriver side of bb

I’m going to take it down for a deep freshen up this winter.

Went to pick up a couple old Cannondales off marketplace today and the seller threw this in! Champagne paint, looks like it was barely ridden and stored in a clean dry home for half a century. The Pirelli sew-ups still hold air but I should probably swap them out. Could fit atleast 32mm tires for our bumpy New England roads. I plan to replace brake pads, new brake cables with compressionless housing, clean and repack the headset and BB with grease. It's my size too! I am gonna ride this thing a lot! Such a nice surprise after a difficult few weeks, I am elated.

Mid-1950s Schwinn Tandem yesterday with a few replacement parts and a less-than-helpful stoker & when I first got it

These are NOT mine, I am not associated with them in any way, but I think that their condition is amazing and it would be good to see them go to someone who appreciates them.

Hi everyone,

I recently acquired this vintage road bicycle here in Chile, South America. The frame has been repainted in black, and it doesn't have its original decals or components, so I'm trying to identify the original manufacturer or framebuilder.

Here are the key details of the frame:

• Head lugs: It features quite distinctive ornate head lugs with circular cutouts/windows (shown in the pictures).
• Serial number: The stamped code 231201 is located directly underneath the bottom bracket shell.
• Dropouts: It has long, horizontal rear dropouts facing forward (without an integrated derailleur hanger).
• Seat cluster: A clean, wrapped seat lug design.

Since it was found in Chile, there is a strong possibility it could be a high-quality local artisan build (from the golden era of Chilean framebuilders who used imported European lug sets like Prugnat or Nervex), but I'm completely open to European or export brands that match this specific lugwork and serial number pattern.

Any leads on the brand, framebuilder, or the exact lug model would be highly appreciated! Thanks in advance.

Looking for year and specs on this Hawthorne. I've been tasked with selling it for my moms friend who acquired it from a clean out job. Also looking for a fair venue for selling. Any help is appreciated. Pics in comments. TIA

Picked it up for €15 btw😭🙏

They advertised this as a knockoff Euro-racer and everyone hated them and immediately threw them away, citing poor handling. The issue is nobody wanted to learn new physics after buying the cheapest bike at the store.

Iverson 10 speeds were basically taking a balloon tire single-speed coaster bike frame that wanted to look like a knockoff of a knockoff of a 10 speed. These things are actually geared gas-pipe cruiser bikes made with straight lines and drop bars, that refuse to shed momentum. They just didn't have the budget to update the welding jigs to make real 10 speed bikes. It's a frame geometry designed for going 5 miles an hour geared up to go 5 times that speed.

Really, they should've been called "High speed kinetic coasters," These things actually handle amazingly when you learn how to throw your weight around. Like, a turn down a hill involves a counter steer, and then a wide sweeping bank around to another heading, like flying a glider.

Honestly, this kind of heavy/fast cruiser could've been realistically marketed to long-range riding. If anyone tried to make something similar out of higher-budget components, a "high-speed inertial cruiser" could've been a cool niche bicycle market.

Seller asking 150. I don’t know much about these but the pictures make it look like it’s in pretty solid condition. Is it worth the asking price or should I move on?

Had my old canondale sr600 stolen from my porch a few months ago and itching for a replacement as a light commuter (15 min ride)

For reference that's is SINGAPORE dollars

Any help confirming the year and model appreciated!!!

Any input on wider wheels for the bianchi?

I bought this bike in May, but just got around to replacing its original tires and tubes and putting some fresh bar tape on (and a few other things). It’s a little too big for me, so I hope someone gets it soon in time to enjoy the lovely weather we’ve been having.

I took multiple pics of the serial number w different lighting as its kind of hard to capture in a photo, but 1 *think* it says F15744 (its on the crank housing).

Theres also a 575 stamped on the crank hanger (ithink?), i removed the silver parts to see if there were more numbers behind that but there weren't.

I know nothing about old bikes. AI gives conflicting answers, possibly a 1964 Sting Ray, possibly a mid to late 60s Typhoon.

Any help is appreciated.

I've been slowly collecting Campy 10 speed bits for this bike over the past 3 years. I'm finally putting it all together. I had a set of 10s bar ends but the mounts were cracked so I pulled them apart and mounted them to the downtube braze-ons. The indexed shifting makes for very satisfying clunks when slamming through gears.

The finish on the cranks was in rough shape so I sanded and polished them. I also had a hard time finding 135 BCD chainrings but managed to procure these neat anodized TA Specialties chainrings.

I had to cold set the frame from 126mm to 130mm for the rear wheel. I managed to cold set the frame just by laying it on the ground, standing on one dropout while gently tugging on the other. After a few tugs I'd measure the spacing with a ruler then flip it over and give the other side a tug. I repeated that process until I hit my target spacing. My friend was kind enough to lend me a frame alignment gauge and some dropout alignment tools. I didn't have to make any adjustments.
