Bent rim = repair or just buy a new wheel?

I picked up a nice old 2005 Scott S1 Speedster but it has a rear rim bent so badly (dented) that it can't be repaired. The wheels are Shimano WH-R550 and the rear is 20 spokes. Specs are here

velospec.com/components/shimano/whr550

I can't find an exact replacement rim online, but a similar DT Swiss rim is about $80 - $100. Add in the charge to repair (I'm not that good with wheels) and it seems I might be better off just buying another complete wheel? Unless there is a source for the original (I'm hoping less expensive) rim? The hub and spokes otherwise seem fine.

The WH-R550 wheel sets use straight pull spokes with the nipples at the hub end and a specific rim design that takes the nail-head end of the spokes. I don't think any rim intended to take regular J-bend spokes with the nipples at the rim end will work. so, unless you can source an exact match(or WH-R560 rim) I think you are out of luck. Look here for details and part numbers:

Thanks for the reply. That's pretty much what I suspected and confirms my wariness with "novel" bike part designs. It may look cool, weigh a gram less and offer a two-second advantage over ten miles, but come next year parts will be unobtanium. I'll keep an eye out for a similar wheel (as I have the "matching" front) used, but otherwise consign it to the parts bin.

There's no stock rims for that wheel. Maybe contacting shimano? Good luck with this one, you will need it.

Nothing novel about any design like this anymore, this type of design has been fairly standard for 10+ years now. For spares, Shimano are better than most for availability, cost effectiveness vs complete replacement is another thing. With Shimano max 10 years / 3 generations is about the norm for availability, being realistic, if you have parts older, they will probably be worn out by that time.

You'll find WH500 wheels and wheelsets where they sell used bike parts e.g. eBay.
