It also doubles as a rucksack and the shoulder straps are removeable to use to tie to the rack. It's better than a sack as it has a big zip around the front and can easily slide your hand in for items. I put items in plastic bags for ease of accessability. It also means you can strap a tent etc to the flat surface. I reckon it's easily about 26litre.
That looks a very neat solution bigjim.

Re: Cycling Eutopia ?

CTC Forum - On the road - 17 October 2014 - 9:49am
I'd like a rule which gave 1 mile of cycle track (on-road or separate) for each new mile of road that is created or re-surfaced. Wouldn't take that long to have an improved transport system.

I agree with you Mick, to be Utopia I would need a lot of variety in the scenery. Cycling in Denmark is fun but it is lacking variety scenery-wise. Cycled there this year and last year. Preferred Holland as at least there were lots of waterways but both countries have much better provision for cyclists than the UK

You see lots of people dressed in black. So why should that change if they want to ride a bike somewhere?

I avoid black and grey for cycling jackets but only because I don't really like them as colours for any jackets, and being a stocky slaphead I tend to look like a bouncer when in black. But it's really just a personal colour choice, a bit like having a black car.

More than an inclination for me. Put a decent hub dynamo on and connect it to modern LED lamps and that's your lighting problems sorted for the whole way. Use automatic lights like BuM's "Senso" models and you don't even have to worry about deciding when to turn them on... You can override the sensors and just use them as daytime running lights (bulbs blowing very much less of an issue with LED tecnology, it's not only brighter but a lot more reliable), and that takes a way a lot of your hi-viz-without-the-hi-viz issues.

I'm not a big fan of hi-viz, but there is a big difference between "colourful" and hi-viz. While you might like all-over black there are practical reasons of overheating in the sun why you might be better off with some alternatives, at least some of the time.

Be aware that in training these days position is emphasised as probably the most important part of being seen. If there is a small pothole in your track you generally see it despite it being small and nothingness because it's where you're looking for things. It's not required that it be surrounded in dayglo paint. But if you're not looking it doesn't matter if it is surrounded in dayglo paint, because you're not looking. Same goes for drivers and cyclists: if they don't look they won't see you, if they do look you'll be seen. Once seen research has now suggested there's no difference in e.g. care in overtaking of riders in loud clothes.

Well you wouldn't see any acceleration/deceleration if he was maintaining road speed, would you!? However to me he looks as if he's moving past the camera guy at the time of collision. He certainly doesn't look as if he was pulling back.[/quote[

Sorry - I was unclear. In order to maintain speed along the road, whilst travelling diagonally, he would have to increase his speed over the tarmac. I'm not sure he does this, so his sideways manoeuvre inevitably adds a "backwards" component relative to the riders around him.
It is this component that is exacerbated by the rapidity of the manoeuvre.

A more gentle change of direction would have reduced this component (which is possibly/probably what caused the collision) as well as allowing time for the component to have been observed and accounted for by the other riders.

OT: Had it been me behind then the rider in front might have been in a world of pain - since his rear wheel would have been caught by my feet/pedals which can't "give" sideways, so he'd likely have been down, with me completely unable to stop before running him over.

Poor judgement by both, but only one of the riders actually caused a collision.

Additionally we don't see long enough, but the forward rider certainly stops pedalling, but then starts again, implying that he didn't stop. Note that this is speculation.

EDIT: Just read the description on the video:
"The guy in the silver and blue Pinarello cut-off in front of a rider and took his front wheel out. He saw the accident he caused and sped away."

If you see them, it can't be so bad for visibility Do you find the continuing use of black cars baffling, too?

Back to the original question: I didn't have a problem in NZ (except the blasted helmets) but there wasn't much traffic where I was riding. In the US, there was so much traffic that most of it didn't move very fast - I did avoid big roads because I wasn't going anywhere in particular.

I think I'd be inclined to use a dynamo if I wanted lights most of the time, or a good "be seen" set of lights if it was just for occasional use in areas of poor visibility and few cycles - many Cateye or Smart ones seem OK for that.

We've already said that the guy in front is partly to blame, and this is yet more repetition on that. I guess what I'm saying is that once the rider behind tells the guy in front to go ahead then his actions resulted in an assumption of duty as well i.e. part of the onus is now on him as well.

The onus is on the person making the maneuver to ensure that it is safe, and he didn't even look - it's a couple of seconds between looking and swiping. Interestingly his hand also comes over the front of a brake lever - doesn't look like he touched the brakes though.
You can't say that the guy didn't even look. The guy looked twice; as he was indicating and when the rider behind said “go ahead go ahead” just before he pulled out. The brake lever thing is interesting.
The rider behind clearly said something and if "go ahead" didn't mean go ahead then he has to accept responsibility for that. The fact that he said go ahead means that part of the onus is upon him as well. I certainly wouldn't wave someone out if my safety was dependent upon them waiting until the gap got bigger, or having to suddenly go much faster. As it it I suspect the rider behind meant go ahead and he didn't spot the wheel overlap.
[XAP]Bob wrote:The rear rider makes an error of judgement - either in terms of space or in terms of word choice...
Agreed, the rear rider and the front rider as well. Fundamentally we seem to be agreeing (I think!)

I took a Nexus 7 (new model) on our five month tour round Britain this summer. I added a cheap blue tooth keyboard for typing the blog. I really couldn't fault it in any way. The battery life was adequate and we used a top up battery for backup. The keyboard (I'm typing on it right now) was excellent. Not the cheapest option I know but it did just work so I'm happy.

The requirement to use your own judgement isn't limited by the signals of other road users.
I’m not certain of what your point is here. The HC rule you quote states that flashing headlights is not a signal to proceed. When read in context with rule 110:-
Highway Code 110 wrote: Flashing headlights. Only flash your headlights to let other road users know that you are there. Do not flash your headlights to convey any other message or intimidate other road users.
There’s obviously a big difference between someone flashing their headlamp to alert someone, and giving a clear verbal signal to proceed. However if your point was that the guy in front failed to spot that there was insufficient room to pull out then I’d agree. In fact I've already said that both riders must have misjudged the gap and they are both responsible for their actions.

The point is that the onus is always on the person making a manoeuvre. (We'll return to the verbal signal at the end)


Sum wrote:[XAP]Bob wrote:I hadn't heard the "go ahead, go ahead" on first viewing, but my opinion isn't largely altered - the change of road position was aggressive, and unnecessarily so.
We don't know that but what is clear from the video that the guy indicated to pull out either into or across the paceline and the guy behind told him to go ahead even though there was wheel overlap.
[XAP]Bob wrote:If you change direction like that then you (by definition) reduce your speed along the road (since you are travelling across it). It looked like a very small clip, possibly the gap was there for a gentle cross, but the rapidity of the manoeuvre required a larger gap.
Only if you don't accelerate to compensate. Again the video doesn't bear that out. The cyclist seems to be accelerating to overtake the camera guy (before he did a runner!) The guy behind may have misunderstood the intentions of the other guy, perhaps not expecting him to pull out as far as he did as you suggest, but if that was the case then that simply means he made an error in judgement when he said "go ahead". The "use your own judgement and proceed carefully" applies equally here.
I've just rewatched the video and can see no evidence of a strong acceleration (as would be needed to maintain road speed). However it is very difficult to see any acceleration anyway. His cadence doesn't seem to increase at all though.
The onus is still on the person making the manoeuvre.

There is a train that spans the river where the closed vehicle bridge goes. That train is currently running over a completed bridge. I arrived at the station minutes after it left (I wasn't even aware of it until I got to the diversion). I have no idea where it goes or stops, but if it stops on the other side of the river, I'd try to arrange my exit from Porthmadog to meet the train and take it over the river instead of riding the A roads that make up the diversion.

What route did you take? 2 hours is an awful long time to have to wait for a train to continue the journey. Or are there other options for crossing in that area? The route I plotted seemed the most direct route for getting around the close bridge.

I take it that they're still doing construction on the bridge? Might explain why I was unable to plot a course over the bridge on RideWithGPS (and why NCN 8 disappears on that section too on same site).

I rode the signed diversion following the 2 A Roads you have in your route linked above. My stopping place that night was Dolgellau, so I didn't have 2 hours to wait for the train. Had I know about it, I would have adjusted the time I doddled in Porthmadog to catch it.

There is to reason to ride on bike-unfriendly A roads when a 10 minute train ride (if that) is available.

Lighting a bike/high vis on tour

CTC Forum - Touring & Expedition - 17 October 2014 - 2:07am
On tour in NZ I used a bright Cateye flasher on the rear at all times. Even on a bright day cyclists can be difficult to see in time when travelling at 100kph, particularly in wooded areas where you may be moving in and out of dappled light.

Cateye has a rack mount that fits Tubus racks and probably other brands as well, allowing Cateye lights to be mounted on the rack. My rack pack is a brightly coloured Alpkit Gourdon which aids visibility too

I also don't plan to ride at night carry a Cateye front light in case I caught out, and after a truck started crossing when I was halfway across this long one-lane pick-a-plank girder bridge where a cyclist is easily lost from view amongst the girders on a bright sunny day (yep, one lane for everybody, cars, trucks, trains...and bikes).



Otherwise I do wear bright cycling clothing but not hi-viz. The NZ company Ground Effect makes an excellent range of plain cycling clothing so you don't look like a billboard. Once off the bike I change into street clothing. Look at MacPac and Icebreaker, all very suitable for NZ conditions. Most other tourists I met wore also cycling clothing.

Yes, but that's not we're debating here is it. We've already said the guy in front is partly to blame. We're discussing the actions of the guy that told him to pull out even though there wasn't room.

If you was in the position of the guy behind, would you still tell the guy to pull out even if there wasn't room for him to do so. If you did, and caused a pile up, would you still expect others to ride with you? I wouldn't. I wouldn't ride with either TBH.
