Non-Thorn Related / Re: Clothing suitable for cycling with a high UPF factor

I bought a couple of Legionnaire type hats from Mountain Warehouse - similar to a hoodie but without the jacket - they are great off the bike, Factor 50 and good neck / ear protection with a big peak….BUT…when cycling the airflow over about 15 / 20mph blew the sides backwards exposing my neck and ears.

I then bought a wider brimmed round hat (bush hat?) from Mountain Warehouse that has 2 layers of cotton and sewed an elastic chin strap onto it that pulls the brim down on the sides to protect my ears.  No problems up to about 25mph!

Hello,
On my Thorn Raven Twin, I replace my chain about every 7500kms and have just recently replaced the chainrings and sprocket for the first time after accumulating about 44000kms.

Hugo

44000 kms with a Rohloff Sprocket ! Are you sure ? it’s a lot of kilometers
If you change the chain often enough, you can make a sprocket and chain ring last almost indefinitely.  The question is if it makes economic sense, as in - are you spending more on chains than you would replacing the other components? There is some disagreement on the answer to that, it depends... IMO it makes little cost difference, but letting it all wear out requires less maintenance.
I swapped (Or flipped) the lot on my Mercury at around 27,000km, though that bike doesn't see the worst of the weather or much off-road. On the wet weather/off-road Nomad I'm still expecting 15,000+ km.

Apologies for not replying, I must have missed the notifications. I had the seller photograph the BB and figured the sizing codes out from those photos.
If you are the new owner Binky, hope you enjoy!

I just discovered sun hoodies this year through an advert on social media. I found out that Mountain Warehouse had them for cheaper in a sale and ordered one. I'm impressed so far, haven't used it cycling but have spent a weekend hillwalking in it. The one I have is definitely long enough to not expose my back when in a cycling position.

Do you think 26x2.30 tires are ok wirh the Nomad MK2 ?

I have used Schwalbe Marathon Mondial 55x559 with mudguards on my Raven Tour frames, these have slighly less clearance than a Nomad.

So 26x2.30 should fit a Nomad. But perhaps not with mudguards?

There is also the issue that advertised tyre sizes don't always correspond to the true size.
