TL;DR
Found an old 26" wheelset (Mavic X139/Deore M510) and wondering if it's worth saving for an hybrid bike build as a second bike for my summer house.

I found an old 26" wheelset in my closet and need some advice on whether it's worth restoring. I'm thinking about building a hybrid/XBiking setup for my summer house instead of bringing my gravel bike every time. These wheels might be a good fit, but I’m not sure if they’re worth the effort.

I’m still a beginner when it comes to wheels, so I’d appreciate some input.

Issues:
Rear wheel: 6 loose spokes
Front wheel: Corroded valve area

Both seem straight, and the hubs spin smoothly (I can regrease them myself). However, I’d need a shop to replace the spokes and true the wheel.

I’m also unsure if the rim brake surface is in good condition—can you tell from the pictures?

Specs:
Rims: Mavic X139 599×17 (V-brake)
Hubs:
Deore HB-M510 (front) /
Deore FH-M510 (rear)
Weights: 885g (front), 1085g (rear)

Would love to hear your thoughts – would you restore them or it's not worth wasting the time?

  1. A true up at a shop might cost $20-40 for both wheels. Braking surface looks good, the rim has no cracks at the spoke holes, and the hubs just need a little grease as you’ve identified.

    If they’re worth $40 to you, I’d say go for it. If they *aren’t* worth $40, there’s no harm in getting a spoke wrench and learning to true them yourself. Worst case scenario, they head to the bin they were off to anyways.

  2. I’m with /u/fastsloth6

    However, you mention using a shop to *replace* the spokes. Is there something known wrong about them besides being loose? How loose are they? How out of true is the rear wheel?
