I agree with both. I have no wish to outrun motor vehicles – my priority is to be safe on the road. There are occasions, however, when I do feel it necessary to keep pace with traffic on the described road. At busy times, cars can still be travelling in excess of 10mph in both directions, with little space between. In choosing not to keep up, I would be inviting regular close passes and cutting in front, compromising my safety. Parked cars line the sides so primary is a must. I don't do more than 20mph max, and only then if the road is completely clear. I'd normally be flattered to be equated with a race snake, but it's simply not the case – hence my username

Slightly off topic but, having read the recent thread on shared paths, there's a different take on cycling speed here:
I just wish drivers would appreciate that a cyclist wanting to do 20mph is perfectly reasonable, but does also mean they need to be on the road, as that sort of speed isn't suitable for shared use paths.

Re: Ten Miles a Day

CTC Forum - On the road - 29 July 2014 - 9:06am
Yes, it's a good thread and it makes me think about riding more. The mileage idea has got me thinking ..............

I found last year, that I was finding easy miles just to keep the averages up. It led me to go out five or six times a week, but generally not many miles at a time. This year, I'm going out less, but going further.

Also, I wonder what the difference is between easy miles and hard miles, and how to differentiate.

This year so far, for instance, I've done 2,950miles and climbed 261,000ft of climbing.
Today is Day 210 of the year, so I've climbed 1,243ft per day. I wonder if I can manage an average of 1,300ft per day? This may make me find more hills.

Re: Shipping the bike by plane

I agree, why did you remove the front wheel?

I reckon box it or leave it as much like a bike as possible. Remember that the baggage handlers will not be taking lots of time to put it 'the right way up'. Will it be OK laying on the front wheel? Throw it round your lounge a couple of times and see what you think.

Also agree about safeguarding your helmet. Even dropping a helmet may mean it should be replaced, using it to protect against baggage handler damage seems a bit daft. How would you know if it received a heavy knock.

I think you'd be fine taking the TER option. If you can change your plans slightly, an alternative to the taxi from Roscoff to Morlaix would be to cycle, it's less than 30km.

Re: Anker Cache Battery Broken USB Connector

But again you'll need to come up with a way of keeping the full size USB lead in too without over straining that connector! One idea might be to glue the large USB lead into the adapter, with a bit of packing between it and the battery body.

Poking around I found some other right-angle connectors which look like they would mount flush to the side of the battery better which may help.

Re the higher capacity E5, I deliberately didn't chose it as there are reports that the built in flash light switch is easily knocked on in transit. In any case I've found the smaller capacity Anker without the light is more than sufficient capacity, especially if you have a couple.

Thanks for the heads-up. I wasn't aware of that concern.

Not sure about the 2nd gen device. First, charging via the E-Werk will take a very long time as the higher the set voltage the lower the current output.
These aren't accurate figures, but most hub dynamos output 3W / 0.5A 6V AC maximum. When converting it to 5V DC, the maximum current will be again roughly 0.5A (assuming no conversion losses, which there are).

It was an early option which I have since discarded in preference for USB charging pretty much for the reasons you give plus one less power point plug to take as well.

Thanks
Andrew

Re: 50 mph for lorries

CTC Forum - On the road - 29 July 2014 - 12:34am
While a nominal default limit of 50kph is indeed slightly higher than 30mph - most European countries (certainly those with a good road safety record) make extensive use of 30 kph limits throughout urban areas - while in the UK it is common to see higher limits of 40-50 mph on suburban residential streets.

For stability any speed above 6 mph will be stable.
Depending on the town, size of road and time of day, it's perfectly easy to keep up with and even exceed the traffic.

In typical urban traffic conditions a bike will make progress faster than cars - however at any particular part of the journey you are likely to be moving either faster or slower than traffic at that time which will tend to have spurts of speed and time spent in queues. If you happen to be keeping up with traffic at some point that will be entirely coincidental - either the traffic at that point may happen to be matching your desired speed (whatever that is) or you need to slow down due to congestion and there isn't space to overtake.

If a driver has a choice of speed (ie thery are not in a traffic jam) then they will pretty much always want to be going faster than any cyclist they encounter. You can control inappropriate overtaking by riding assertively, but you are not going to outrun motor vehicles (even if your name is Tony Martin) unless you are going down a steepish hill with gravity on your side.

Gijon to Poole Ferry

I'm planing a trip around Northern Spain in September and looking for transport options to and from Spain. It looks like LD Lines are starting a new ferry service from Gijón to Poole which would be a great departure point after Leon. The website is very vague, does anyone know more?

With the E-Werk voltage set to 12V DC, the output current will drop by a corresponding amount, ie to less than 0.2A. The E-Werk circuit doesn't somehow create charging current out of thin air, and can only work with what it's provided with from the dynamo.



Looking at http://www.forumslader.de/typo3temp/pics/590d4cd9bb.png

...my understanding is that at 20km/h the 12V and 5V settings of the E-Werk cross over at 3W, but at higher speeds, both can give more power, with the 12V setting giving over 5W at 32km/h. That would equate to 0.42A. This is because the E-Werk is presenting a load that is different from that required to clamp the dynamo at 6V.

I'd agree that speed and the ability to stop in a safe manner are to be judged carefully, but it's difficult to know the limits of a new-ish bike until those limits have been exceeded.

I'd bet the differences in road deaths in different European nations are largely due to factors other than speed limits.

Actually if you break it down by road type then speed does feature stronlgy.

The UK performs comparitavely well in terms of road safety for car users. Since a large proportion of car mileage is on motorways then this is strongly influenced by our reletavely low motorway speed limits, making our motorways some of the safest in the Worrld.

The UK performs extremely poorly with respect to the safety of vulnerable road users - who are to be found on the non-motorway roads. Here our reletavely high speed limits lead these roads to be relatively dangerous by European standards.

And most of those vulnerable road user deaths are in built up areas where Britain has slightly lower speed limits than most European countries. 43% of pedestrians killed are over the alcohol limit for driving with 34% at least double the limit. I wonder how that compares with other nations. Only 13% for cyclists though.
Anyhow I'd like to see comparative statistics if you have any. For example are vulnerable road users safer in Albania or Serbia with their 50mph limit than here with a 60 limit.

Of interest to you may be this: http://spacycles.co.uk/products.php?plid=m1b0s21p3106 - £950 for a spa cycles 3k carbon framed bike with full shimano 105 (and a triple!) is a bargain. It doesn't say in the description whether the frame takes guards, but i would guess it does because the specced brakes are deep drop.

JUst noticed Ribble Sportive 365 Campagnolo http://www.ribblecycles.co.uk/sed/road-%20...%20=conf_SERW can take 25mm ryres and mudguards so suitable all year round ?
Don't know it's weight. I was thinking of a Specialized Roubaix, but is this better ? Realise it costs more than the Winter Audax at £1000.

Re: Ribble Winter Audax bike

Anything comparable to Ribble winter audax but can take 25mm with guards? Prefer to be in similarly priced.

That's a fair comment. While I'm not sure about the 'largely', it's certain that reduce speed limits only help because they are enforced. And other factors will contribute as well. How much each factor influences it, is impossible for me to say.

Adds to the adventure then! Get a Basha tarp and find some invulnerable spaces to bed down.

When I was doing it in NZ (one of the easiest to I imagine) it was cold, so I was desperate for shelter (before upgrading my gear) going a bit far by bunking down in derelict barns, not so derelict barns, unused holiday home sheds and even a section of an assault course of a school. With the barns, a kiwi told me they would have gone crazy if they found me, yet if I just asked they'd say "no worries". Always best to get locals advice..
