Re: Dawes Galaxy Seat Post Size?

Wilhelmus wrote: 22 Nov 2021, 1:06pm Thanks for doing that, especially on such a morning (unless it's somewhat warmer down there than it is up here). This morning was the first time this year that we've had to defrost the car windows. It intrigues me to see the neighbours pouring kettles of hot water over their windscreens. Long may their luck hold. We have a convector heater in the rear compartment, which we attach to an extension lead and plug in for a few minutes, whereupon the ice melts like magic while the toast is doing. Also nice for Herself to be able to drive away in a lovely warm car. But I see I'm digressing. I shall order an inexpensive 26.6 mm post from a certain online emporium and, should it be too large to fit comfortably, get a 26.4 mm one, maybe a little more expensive. Regarding the method of dividing the circumference by pi, all very well in theory, but I imagine that the slightest error, of which I'm more than capable at my age, would be disastrous. Anyway, to how many decimal places would you take pi? It reminds me uncomfortably of maths at school, at which I was a duffer.
If purchasing a painted (or cheap anodised?) 26.6 seat post it will be possible to get 26.4 with sandpaper. Just take away the section needed. I was able to fit a 27.2 seat post to a friends 27.0 seat tube this way. The fit was perfect.

Re: Shimano chainring compatibility chart - such a thing?

Steel chainrings last tens of thousands of miles with a minimum of maintenance. Chainrings don’t wear on train journeys. The Octalink interface will turn to mush long before a ring will need replacing. Therefore the crank arms and not the chainrings are the consumable on that chainset.

Could of got a brand spanking new chainset with matching rings for £30 but for Brexit. Sums it up really.

Re: Shimano chainring compatibility chart - such a thing?

The complete chainset is found for less than the cost of buying the chainrings individually. Better to put the money towards a significantly lighter and improved design. What’s known as an upgrade.

Re: Lower gear

Here are the two set ups (assuming 35mm width 622 tyre). OP should focus on the top scale (gear inches). The 28t cassette gives a 35 inch gear. The 34t cassette gives a 29 inch gear. That’s a decent jump that will be appreciated but will remain hard work on anything other than short duration climbs. Easier hard work.

I want to try a 11-34T is this the best way to go?
I know I will want a longer mech and chain, what length chain do I need?
Purchase the cassette and derailleur, run the chain around large front and rear. Pull the chain together and add two full links.

Re: Cycle touring: time to ditch the smart phone?

A responsible tour leader / organisation could start by offsetting the harmful emissions their business is responsible for.

A typical European cycling holiday for a UK citizen would I estimate add about £10 in carbon offset fees.

I wouldn’t but why not test it out by putting an amount in a container and leave in the fridge overnight to see if it solidifies. Then place the container on a radiator for half an hour to see if it solidifies. The freehub greases I’m aware of all boast a pour point down to -35deg. I left a freehub body i’d serviced with Shimano freehub grease in a freezer section for a week and afterwards left overnight on a full on radiator. It spun freely afterwards on both occasions. The race teams I’m aware of prefer freehub grease over freehub oil as it withstands moisture ingress better.
