A couple questions about Suntour freewheel hubs

I'm planning to bid and win a wheel set (now at $10.00) with Araya rims and Suntour XC Sport freewheel hubs as a spare set for my mid-80s mountain bike.

1. (And I feel dumb asking this) Will Shimano and Shimano-type freewheels fit?

2. The axles are solid. Would I be better off with a hollow QR setup in the back? I have a hollow axle and a QR. This question concerns the tendency for rear axles to bend or break when used with a freewheel, not ease of fixing flats or changing out wheels. I read somewhere that a hollow axle may be better, but I can't remember the reasons. Am I over-thinking this? These questions are about freewheel hubs in general, not just Suntour.

Posted to C&V because it's old stuff.

Yes, you'll be good on freewheel fitment. What bike are you planning on putting these on?

The bike is 1984-85 Bridgestone MB-2, my all-purpose bike and only bike at present. I'm now running wheels with Araya RM-20 rims and Shimano XT hubs with a 7-speed Uniglide cassette. Like I mentioned, the wheels at auction would be spares for the most part, just in case something happens or when I take my time servicing the XT hubs.

Edited: The rear spacing is 126 mm.

Personally I look at freewheel wheels as a downgrade from freehub wheels but then again, I'm a big guy and universally dislike freewheel hubs because of the axle issues. I'm not referring to the expensive fancy freewheels like Phil Woods but the more common popular ones.

If I bought the wheels you were talking about, one of the first things I would do is rebuild the wheels using a freehub and junking the freewheel hub or donating it to the bike co-op.

The reason why freewheel hubs tend to bend/break axles (I don't think the fact that they are solid or hollow is all that important) is that the bearings on the driveside of the axle are much closer to the center of the hub than the bearings on a freehub. Because of that, there is much more unsupported axle on a freewheel hub and a good chance it can bend/break. I'm 350 pounds and have never bent/broken an axle on freehub but on the other hand, my son who is roughly 275 pounds killed a few freewheel axles on his older MTB bike.

I hear you bobotech and agree for the most part. But if I can get these wheels for 10 or 20 bucks, I'll stick with the freewheel. Upgrading would not be worth it, IMO. As I mentioned, these wheels would just be spares to keep me on the road.
