Are these cracks around the spoke holes?

Had these Hunt 4Season Disc wheels for a couple of years, they've not done that many miles as they are just a winter set (one and a half winters). While cleaning them today I noticed some corrosion on the nipples of the rear wheel and what I thought look like cracks. I'm no expert but I just wondered if they were still OK to use? The front wheel is absolutely fine.

    They look like cracks to me, they need to go in the recycling.
  • Impossible to tell at this resolution. You could just have corrosion bubbles.

    The second pic definitely looks like cracks propagating from the spoke hole, so I'd guess it's quite likely that the others are too.

    If they are in warranty - send back to Hunt. If they're not - into the recycling bin.
  • Given the pics dont enlarge I'm not sure how you can say they are cracks.

    Is this not large enough? https://i.postimg.cc/yNPvm5SR/Hunt-4-Season-spoke-holes.jpg

    Basically, yes, but keep an eye on the development of the cracks.

    Assuming you are the original owner you ought have a shout at warranty replacement of the wheel? They offer a full 3 years to the original owner.

    Certainly I'd have thought it'd be safe to ride them to the end of winter then get them warrantied.

    Failing that a local wheelbuilder should be able to replace the rim for not a huge amount of money.

    Thanks for the advice. I'll send the pics over to Hunt, as they're still in warranty and see what they say. They're still on the original bearings, everything is running really smoothly and the front wheel is absolutely fine so it just seems a little strange.

    Not that strange, it happens a lot. Basically rims and wheels tend to be under built for the intended use.
    28 spokes on 25-30 mm deep rims weighing < 500 g seems to be the norm these days.


  • Hi Skeetam,

    Ollie here from HUNT. Sorry to see this issue - from what I can see it looks like you do have some hairline cracks emerging from the spoke holes there. Absolutely no problem to get these replaced for you under warranty.

    I see you mention you've sent in the images already, so I'll follow this up internally to ensure you're being looked after to our usual standards.

    Happy Holidays :smile:

    Hi Ollie, thanks for responding personally on here. This thread was obviously not intended to say anything negative about Hunt, the two sets of Hunt wheels I've bought have performed great. I just wanted to see what the wise heads on the forum thought before contacting you about it. Much appreciated :)

    Yeah, lots of factors nowadays meaning that spoke hole cracks are fairly common sooner or later.

    For a start, disc brakes mean that rather than wearing the rims out through brake abrasion (which a winter and a half of usage might well do) the rims are still going - so something else will give sooner or later.

    Then there is the fashion for rims not to be eyeletted, or particularly double eyeletted - any sort of eyelets will make cracks somewhat less likely (or at the very least, harder to spot) but double eyelets in particular should do a better job spreading the spoke load across more of the rim - unfortunately it's near impossible to use them tubeless, and nowadays people expect their wheels to be tubeless so they're out.

    Then there's the trend for wider rims- they don't want to make the rims heavier, so instead they make them thinner....and the increased dish of the 11 speed freehub standards... etc.

    Not for me they dont.

  • Washers should be used with most rims now. Washers also make building easier too. Do these hunt wheels have washers?

  • timothywtimothyw Posts: 2,482
    I'm not saying that washers don't help, perhaps they do, but they don't solve this problem as I've had it on two kinlin rims despite using washers.

    Conversely a set of Dt Swiss rr585 rims without washers did not have this problem.

    Remains to be seen how I get on with the current dt rr511 rim which mandates the use of washers (and comes with them supplied).
  • Bump. Looks like I've got a similar problem. I've already emailed Hunt with photo attatched but haven't had a reply yet.

    If you wanted proper cracks on nearly every spoke hole Planet-X Model Bs were the best bet.
