Hi Ian,

A couple of notes from my experience over the past 10-15 years:

I've had very good luck with Thermarest products.  I currently have three:

(i) a Pro-Plus small:  I used this a lot when I was canoeing, between about 2008 & 2018.  It's been comfortable, durable, and quick to inflate by mouth.  Only downside is slight bulkiness when deflated & rolled up.

(ii) a Neo-Air Extralite:  Have had this since 2015, and used it esp on cycling tours, because it packs down so small and light, and its very comfy.  There are a couple of "buts":
    > it's not as wide as the pro-Plus;
    > it slides around in the tent at night;
    > it takes a while to blow up by breath, even though I put relatively little air into it; and similarly to deflate and roll up snug.  That's better done on a picnic table than inside a tent.

(iii)  a Thermarest foldup (accordion-style) foam seat cushion:  Bought this earlier this year, and I use it a lot:  under my hips when lying down during yoga or other exercises; under the Neo-Air in the tent, for extra padding for my hip joints.  It weighs about an ounce, takes up little space, and is vastly superior to the  small inflatables it replaced.

Cheers,  John

Interesting.

I was sure that my Nomad Mk II and Sherpa did not have exposed breather holes and I thought somewhere that I read that Thorn frames do not have them. 

I copied this from the brochure I relied on when I ordered my Nomad Mk II frame and fork in 2013, I added underline for emphasis:

... ...
In order to do this, I contacted the finest frame
builder in Taiwan once again.
These people make the top end models of some very
famous American brands!
The first time Robin and I actually met them was at
Eurobike, our builders explained that they had to
send the frames with a little sticker saying “Made in
Taiwan” but it could easily be
removed and that is what the
American companies did. I told
them that they came very highly
recommended and that I
wanted our “hand-built in
Taiwan” decal applied beneath
the lacquer, where it couldn’t be
removed. There was a silence as
what I’d said was translated to
the others. Then they looked at
each other, nodded and then
their faces light up with a smile,
they all stood up and bowed and shook our hands. I
still get a warm feeling when I re-live that meeting
and I can attribute it to their willingness to make
certain that we get all the minor details that we want.
Such as having all the blow holes filled in. (These
small holes are necessary when manufacturing the
frame, to avoid exploding tubes!) yet they can let
water in. I believe that these holes are still present in
all the Americans’ frames!

That is from the Nomad Mk II brochure, Issue 20, Autumn 2012.  I did a quick word search for moisture, did not find it, searched for water and found that.

Even though my Nomad Mk II had those holes filled in, I still used a rust inhibitor inside the accessible tubes in my Nomad, but there were not many.  I think I only treated the seattube, top tube (both halves, it is an S&S frame), Downtube (both halves) and headtube.  To access some of those tubes I had to remove a piece of tape inside the headtube that blocked off the top tube and downtube.  I had never thought of using tape like that to prevent water ingress to those tubes, so I made sure I replaced the tape when done.  The seattube and downtube both had water bottle cage bolt holes where water could get in from capillary action.

So, apparently either this was missed on that frame, or Thorn has changed their policy.  Or, perhaps that feature was unique to only certain Thorn frames.

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, at first glance I thought it looked decent value for the bike.  Then I noticed it was just the frame, well used (To put it mildly) for more than it originally cost!

Yep, it is a steep asking price but I'd guess it includes fork (maybe not) though its not got rack mounts, so... A new Nomad mk3 frame from SJSC is £999 not including fork. The listing is for £797 or best offer so some leeway for a more realistic price. Its definitely seems to have had a fair amount of use. What would you think to be a reasonable price? About half that?

On another note. What is the parachute like addition under the handlebars? 🤔

Hi, just checking back in with this forum.

In terms of frame sizes, I’ve posted the serial numbers below

Both are ‘L’ according to the SNs (Green = 587L08025, Red = 487L07005).

Effective toptubes: 40cm (Red), 42 (Green)

Stand over heights (tyres are flat so I’ve given a range): 70-71cm (Red), 72-73 (Green)
