If you are concerned about the empty hole next to the Phillips head screw, you can ease your concern. The cable guide typically only needs a single mounting screw. The extra hole allows the same cable guide to fit a variety of bikes by shifting the guide towards the drive or non drive side depending on which hole is used.

The thread repair tool that is used in this sort of situation is called a die. The common size for crank nuts is M8x1.25. However, too much material appears to be lost here for that approach to be reasonable. Crank nuts/bolts are one of the higher torque items on a bike, meaning you don't really have much leeway for severely damaged threads. Also, hardened ...

They are rack and fender mounts and you cannot install disc brakes with them. I.S. mounts are 51 mm apart, and post mounts are 74 mm apart (and look totally different). For more details on these mounts, see this answer.

From the information available your bike uses a 1-1/8" quill style adjustable stem. The only other pertinent variable is handlebar diameter. While you most likely have 25.4mm (1 inch) bars you could have 31.8mm bars. Locating replacement bolts will likely be difficult as the pinch bolts of pivoting stems are typically brand specific in terms of length of ...

You have the seat stay mounts on the frame (those are the two thin tubes that go from the rear wheel drop outs to the top of the seat tube). What you need is mounts on the rear wheel drop outs. Typically, they are part of the dropout and/or frame. In your case, you have none. That being said, the P-Clips and Tubus Clamps will not be useful. The Tubus ...

It looks like to 20" version of the bike comes with a rear linear pull brake, but the 16" has a coaster brake. This is common practice with kids bikes as children young enough to be on a 16" bike don't have enough hand strength to operate a brake lever effectively. I looked into doing the same thing when my daughter had a 16" bike, but found that it is not ...

Check out this thread, the bike in question matches "F4042" S/N portion with yours. According to messages, your bike was built by Formosa in Taiwan (F) in 1984 (4), so it's not Formula One, which was made in Japan. This post mentions that "Viper, Pacer 500 & Super Streak were available that year", but an archived copy of os-db reveals there were also ...

I liked @argenti-apparatus answer, but I just wanted to add that many children's bikes don't come with child size brake levers. You may need to use the brake lever adjsutment screw to move the lever as close to the handle bar as possible as otherwise the child will not be able to physically use the brake.

This bike looks to have a vee brake seen on (now old school) mountain bikes. The popping noise you notice could be the cable housing not sitting in one of its barrels. And, pulling the lever that could cause it to move suddenly in/out of place. It could also explain why the wheel isn't turning well: the housing could pull on the cable, and hence the brake. ...

You're an exceptionally experienced programmer, you know by now that life is a series of compromises and trade offs. Yes the diamondback is a good bike for that price, but you get what you pay for. If you really want a bicycle you'll enjoy, go to a family owned local bike shop and trade a little extra money for an experienced employee to fit you to a bike ...

That link appears to be a dealer-only one, I get a login prompt. It's a flat bar road bike and based on a google search comes with 700c/ISO622 wheels and a 7 speed cassette (7 gears on the right hand shifter). The R23 in the name very probably means the original rim is 23mm wide. That means any 7 speed narrow rim 700c wheel should work.

It looks like it runs a 3x7 Shimano mountain drivetrain. You can get new shifters such as the Shimano ST-EF51's (the 3x7 version; which are switchable between V-brakes and cantilevers -- see manual for details) or the SL-M310 (in the 7 speed version for the rear, triple for the front; add your own brake levers if yours are integrated with the appropriate ...

My first real road bike was around $1300 - so you are on the right track as far as spending. You do have to pony up to get a decent ride and components. I bought a Bianchi, and the dealer is an hour away. I haven't had any issues, but now that I look back I should have bought a bike where I live, so I have dealer support and can get parts/merchandise ...
