@Rеnаud some people just don't sweat. There's always an ebiker with zipped up jacket and long trousers while I'm close to a heat stroke.

Have you seen Chris' 600km in 40h ride?

It only got some spots of superficial rust last week when it was standing on the repair stand in pouring rain for a week. Still plenty of wax inside the rollers.

Wax on my single-speed lasted 600 km. Including standing outside most of the year and plenty of wet rides in autumn and spring.

But why would they put the visor down now it's not raining or cold?

You can put your glasses on a case, visor stays on the helmet.

That would be trouble riding a regular bike too. So you're lucky you got a VM.

probably got hard points on the frame for mounting it on some kind of repair rack? Also for loading and strapping it on a truck (for delivery etc).

do you use something to jack it up, cause it a regular work stand wont hold it.

@Willeke oh, so all works are pretty cramped?

@Willeke is this because you're excited about the new one, or is it simply better to ride far with?

Can you remove the fairing for maintenance, does it lift of when you remove some fasteners, or is it more integral?

@Willeke this is so neat. Must be quite a lot of fun maintaining it.

Is that the chain on your new bike?

so the worst risk for the chain is sweat?

> .the difference an enclosed system makes.

keeping road spray from it will increase chain life considerably.

is your chain protected by the fairing?

Oldest chain is a KMC x10 with 2000km. But that's been on my son's bike. So he weighed between 50 kg and 60 kg while he rode that bike.

However, I think that was too optimistic, as there will be wear from rotation under the straight section. The anlges they move through are smaller, but there's high angular frequency. This should be pretty effective at abrading surfaces.

as meaningful wear only happens around a cog or chainring. Where rollers are rotating and are under load.

your chains are also 4 times as long, so I expect wear to be about 1/4

My aim is to always have a spare chain readily waxed. So I'll add a few more soonish.

after waxing they go either on the bike or in a bag with a note.

I just have to be careful when labelling the chains. So I don't wax large badges. Now I do three, a KMC 10spd, Wipperman single-speed, and Shimano 11 speed. So I can distinguish them.

But the lenghts also have to match, so bike to chain is fixed.

I have more than one for each type. Got single speed, 3 10 speeds, and 2 11-speeds.

so, none of them got too much km yet and none shows any signs of wear.

So they dont

I rotate 8 or 9 chains on 5 bikes.

That's about the wax, not the chain.

I'm re-waxing after about 600 km (dry, dusty rides). But from the feel of the chain moving and the amount of wax that came out of it I expect they'd lasted til 1000km.

By the way, third time re-waxing a bunch of chains, and effort is lower than just cleaning and re-lubing a chain with regular lube.

cleaned three chains in a small container with hot water and 1 drop of detergent. Next day it looked like creme brrûlée. Solid, black, crust, beneath it white emulsion. Part of the wax got emulsified, but all the MoS2 went into the solid wax phase.

You gotta bivvy at work when the bolt cutters don't cut it?

@PaulH komoot uses Open Street Map OSM map data. It was one of their fundamental business strategies. Don't pay for map licenses, use user data to improve open GIS data, improve data yourself (or pay someone) when that's not enough. So a lot of their staff went out for rides or hikes company time to look for weird things in OSM.

It's a plural 's'. 'We' wouldn't fit as it means "I and others" whereas I meant a statistically significant number of instance of myself.

@Sam7919 yes. However, except for not getting obviously stuck from it I cannot tell you about any effects. If I had just a larger sample size of mes.

My conclusion: they want to optimise for casual weekenders who do 15 km. Not sportive riders.

Before, you could prevent that with a single waypoint, but now it just turns you back on it.

It also leads me on any sketchy cycle path, even when road cycling is selected, and when it is not compulsory to take. Even to the point where it routs at a traffic light off the road, on the pedestrian crossing, then back again

It puts a lot of weight on gravel or road cycling. It goes loops, and detours to avoid roads. (For road cycling too, but there it makes more sense.).

Komoot changed something in it's routing:

@Criggie very much indeed! That was one of the reasons I asked.

I must have done a score of 60 to 70 km rides long before Strava. Unfortunately I don't have notes.

My drop at 41 km is much steeper. I have just 20 rides over 50 km (on Strava).

6 km more still. So you'd need still about 32 rides over 82 km. Or in other words of your rides over 76 km 51 are also over 82 km.
