Very observant of you too spot those holes from that advert, I was mostly too stunned by the price to notice anything else.

The listing is for frame only

Yes it's usual.  At one time I also thought it might be an issue, but it hasn't been, I had one bike for 20 years with breather holes in a similar place. The Mercury also has uncovered holes, down by the dropouts. 

I think if I have to have holes I'd prefer the holes at the bottom where any water ingress will drain rather than at the top where any water ingress will pool. Especially if not using mudguards as is the case with the bike in the listing.

No 26” wheel option though 😥
Were you expecting there to be?  None of the models it's replacing were available 26".
Could be argued there's a market for a lighter 26" wheeled bike, I'm not sure there is, but this was never going to be it.

As a hobbyist framebuilder, I plug my frame and fork breather holes with kneaded beeswax after painting.

It repels water and can be poked-out if future access is needed to respray tube interiors or if you change your mind about plugging the vent holes.

Kneading beeswax transforms it, removes any tendency to flake and makes it moldable, useful also as a natural threadlock compound. I have used it successfully for decades on threaded headsets and old-fasioned adjustable loose-ball bottom bracket cups to prevent loosening. I use Blue (medium) Loctite, anti-seize, or assembly lube as appropriate for other threaded applications.

Best, Dan.

The Mercury also has uncovered holes, down by the dropouts.  Frame builders are apparently divided on the subject, the argument being - Keep all moisture out V;s Let the frame breath. Periodically, I spray the inside of my frames with rust inhibitor (I use ACF-50, but there's plenty of choice) I wouldn't get such good coverage without those holes.  I'm not saying anyone needs to do that, but it keeps me happy.

The 40 is now in stock, two colours, the classic grey, plus a fetching orange.  I wanted an orange bike when the colour was everywhere about a decade ago, are Thorn late to the party, or about to start a new trend? The advertising is now clear it's replacing the Audax, Mercury and Club Tour, plus their offering as a Gravel bike, that's a very wide remit for any frame, time will tell if it's too wide.
The frame price for the 40, is £100 less than for the Nomad (899 V's 999 on the SJS website) that's a reversal from the previous Mercury, and I was a bit surprised, I thought they'd be about the same.

Thorn General / Thorn Raven Nomad mk3 frame breather holes?
« Last post by macspud on August 20, 2025, 11:40:18 PM »
I saw this Thorn Nomad mk3 on Ebay and noticed what looks to be weld breather holes on the seatstay. Are they usually like this? Seems a good way of filling the seatstays with water.

See pic 3 & 9 top inner of both seatstays.
