Thnx for responses; I'll try spacers first.
Is it possible to fit the front Chainglider without the rear?
There's the open Chainglider https://www.sjscycles.co.uk/chainsets/hebie-chainglider-open-359-for-38t-chainring/.

I'm pretty sure the front and back clip together.

You may need to fit a thinner chainring as well.  Hebie say max thickness should be 3mm but I have been using 4mm wide chainwheels on 2 bikes with no problems.

Same here.

Since 2011 I have been using a fairly thick TA chainring for 1/8" chain under a ChainGlider on my old utility since 2011. It rubbed a bit at first but soon wore in.

For the chainring bolts, you can either buy a set of shorter bolts, generally designed for use with single chainrings, or you might be able to put the right diameter and number of washers onto the existing bolts to make up the thickness of the chainring cover. I have occasionally done the latter, using stainless steel washers. Aluminium chainring spacers could also work.

Extract from North Face reply re their LightRange Woven Jacket.

https://www.thenorthface.com/en-us/p/mens/mens-hike-263754/mens-lightrange-woven-jacket-NF0A8ES9?color=JV4

Thanks for contacting The North Face Customer Care.
Thank you for reaching out and for your interest in our Men’s LightRange Woven Jacket.

As per the care label on the jacket, it does indeed feature Ultraviolet Protection Factor (UPF) properties. Specifically, the LightRange Woven Jacket offers UPF 40+ protection, which blocks 97.5% or more of the sun’s harmful UV rays.

This level of protection, combined with the jacket’s lightweight, breathable, and moisture-managing FlashDry™ fabric, makes it a great choice for outdoor activities such as cycling. The anti-odour technology is also beneficial for longer trips where frequent washing isn’t always possible.

For your intended use cycling through Europe this summer, the LightRange Woven Jacket should serve you well. If you are specifically seeking a garment with a higher UPF rating of 40–50, please rest assured that this jacket already meets the lower end of that range with its UPF 40+ rating.

Should you have any further questions or require assistance with sizing or placing an order, please don’t hesitate to contact us.

My Thorn Raven has a steel chainring cover outboard of the (38t) ring itself - this came as standard in 2007 (and 100,000+ miles ago) when I bought the bike. If I want to fit the Chainglider I'll have to remove this covering ring so that the chain (only) fits inside (as I understand it). But the present 5 chainring bolts are too long without the cover ring and won't tighten, so it seems I need a new set of 5 smaller bolts. Does anyone have an idea of the spec / size of bolt needed for this? There seems to be a large array of possibilities.

Over my 35+ years of desert touring, I've found it difficult to carry "enough" sunscreen to keep up with effective application guidelines, especially over extended periods of 3-4 weeks at a time. Some sunscreen lotions don't agree with me and my clothing over time, as I can taste it after application and it attacks the elastane elements in stretch clothing.

I've found my solution in sun-protective clothing -- Jerseys, shorts, sun sleeves for arms and legs, and a good "buff" to protect my scalp from sun through the helmet vents and my nose and neck from direct sun exposure.

I wish such things had been available in my earlier years of heavy sun and UV exposure, as I am paying the price now. I have completed repeated rounds of topical chemotherapy for actinic keratosis (pre-skin cancer) and for early-stage squamous-cell cancer and it isn't fun. Sunburn prevention really is key and your future self will thank you for taking precautions now.

My early jerseys and such were sourced from Brazil but as more people become aware, similar breathable/protective clothing that is sport-specific has become readily available as the market need expands. A lot of growth occurred in the construction and roofing fields, where need for all-day protection is great.

Here's some relevant links to helpful products...

https://dabrim.com/products/cycling-classic
https://www.roadbikerider.com/top-cycling-apparel-uv-protection/
https://www.pearlizumi.com/collections/sun-protection

I've found such products can command premium prices when purchased from "name" makers. Similar or identical products can often be found on eBay or Amazon, often produced in the same factories or as convincing, functional knockoffs for a fraction of the price. Tip: If you prefer a full-length jersey zip, leave it open only in the mornings and evenings when UV load is least. Otherwise, reflected rays from the road can really burn your chest, even when cycling on the drops.

Best, Dan.

If you have not had a bad sunburn from cycling before, you might not realize that your legs are exposed to the sun differently than if you were standing or walking.  With bent knees on a bike, your legs below shorts are exposed differently that walking or standing.  For cycling I make sure I put an adequate amount of sunscreen on the front of my legs above the knees and below the knees enough sunscreen on the backs and sides of my legs.  On my arms, the inside of the arms that are not usually exposed to the sun if I am standing or walking get a lot of sun exposure when my hands are on my handlebars.  I use drop bars, so my hands are often on the hoods, thus my hands are twisted a bit differently than if I was using flat bars, thus the insides of my arms, especially near and below the elbows get a lot more sun when cycling compared to other activities.

If you are not wearing normal cycling clothing, don't forget that visibility on a bike is quite important.  On one tour I did with a friend, he wore a long sleeve shirt and a high vis vest over it.  Attached photo, but the high vis color is somewhat muted in overcast conditions, such as the photo.  (Dan has seen this photo before, I think he said it is near home.)  Second photo, days later, where you are in intermittent shade, the high vis is even more important.

I only mention this here because we have some world travelers that look at this forum.  Some sunscreens can damage coral reefs.
