Replacing axles and bearings on 1987 Prelude
Does anyone know off the top of their heads what the axle sizes are? End to end, the front axel is 101mm, and the rear is 152, but I’m not 100% sure those are the correct measurements.
Im completely new to bicycles, so there is a ton for me to learn!
Thank You!

Axle spacing front is 100 mm. Rear is either 126 or 130 mm.

Are you using QR or nuts? Add the dimension of the grooves, and then allocate for nuts if used.

So when I’m ordering axels, the length I need is the full length of the axel, correct? I’m just trying to do a straight across replacement. Nothing fancy here

If you aren't sure of your measurements, I'd bring your current axles to the LBS and compare them side by side with replacement axles. Make sure whatever you buy is a hollow chromoly axle.

...have you disassembled the wheel hubs yet ? It's rarely necessary to replace the axles on an old bike as a matter of course, and I've never encountered an older bike that seemed to have the cosmetic appearance of low mileage (like yours) that needed both axles replaced in order to service them. What am I missing ?
With bearings, you can clean the existing ones and if they are still shiny n the surface, you can re-use them. They are cheap to replace, but it's not always needed.

Schwinn front spacing is screwy, especially with that extra "consumer protection" doohickey they put on both sides of the hub that locks to screws in the fork. I always toss that junk.
Like 3A wrote ... why are you replacing the axles?

I'm also curious how you derived these axle lengths. I'm pretty sure a prelude is 100mm OLD front, 126mm rear, so ~108mm overall for a QR axle, funny Schwinn washers or not. A rear QR axle would normally be ~134-140mm depending on OLD and length variance. The measurement for the front is almost surely too short, and the rear too long, unless it was replaced with a nutted axle, in which case it would be too short.
