First time here! I have a bike that I love, a Redline Metro 9 commuter bike. A couple of years ago a chainstay was bent about 3-4 degrees. It was on a rear car rack and a driver bumped me from behind. I have been riding it without problems so far, but I know it's risky. I just bought a fixie bike for fun (Retrospec Harper), but now I'm wondering if I could have a mechanic take the components from the Redline (crankset, pedals, shifter, derailleur, brakes and both wheels) and put them on the new bike. Frames are the same size, both wheel sets are 700c. What do you think?

The Harper has no accommodations for a derailleur, so that and the shifters won't be needed. Also, the spacing of the rear triangle may be different than the width of your existing rear hub. The crankset might not work on the existing bottom bracket, and its width and spindle length may also be different. A shop would be able to take the necessary measurements and sort out which parts are usable, but the two bikes don't really speak the same language, component-wise. Hope this helps.

Does your fixie have a derailleur hanger? Cable guides and stops for the shifter? Does it have mounts for your existing brakes e.g. studs for V-brakes or cantilevers? Compatible bottom bracket (width, threading?) If your present bike's frame is steel I would not worry about riding it with a slight bend, or about straightening it

The first issue is that the FG has track ends without a derailleur hanger, so you’ll have to get something like this: https://www.fyxation.com/products/qu...ailleur-hanger

Then there’s the question of spacing. Most FG have 120mm rear hub spacing, most road bikes have 130mm. This might be the deal killer here; you might be able to safely spread the rear triangle, but you’ll then have issues if you ever want to put your SS/FG wheel back in.

All the other things can be transferred, although you might need a new bottom bracket to make the transferred crankset line up properly.

Things to think about. Thank you very much for this reply!

No derailleur hanger (would have to buy), yes to cable guides and cantilever brake mounts and I'm not sure about the BB. That's where the mechanic's expertise is needed. After the initial inspection, the mechanic where I bought the bike said it was a good steel frame and that the wheel was still aligned and true but that it was a risk to ride because it could just break anytime, and that bending ti back into shape would just damage the tube further. Maybe I just shop for a similar used frame and get it painted.

Thank you very much for this advice.

Why not use the SS as a commuter? It appears to have rack and fender bosses. And Chicago is pretty flat. How many gears do you need?

M1keZ

It does and I use it as a commuter (even tho I'm working from home ), short hops and store runs. I just got it so will add a rear rack and that's about it. I bought it because i'm getting more nervous riding the bent bike and don't have the $$$ for a replacement bike yet. Plus I have wanted a single speed for a while. This bike is cheap and so far it looks like it will be a pretty good bike. Thanks for your thoughts!

This helps a lot, thank you. I appreciate your expertise.

Could be a fun time to try out an internally geared hub.
