I use the bus regularly, train services in Ireland are quite limited. I think Bus Eireann charge a 12 euro fee for normal bikes, i got a Dahon for my usual trip as there is no additional charge for folding bikes.

I use the Topeak Mini Morph on the bike and it is a good pump. But it can take over 250 strokes to inflate a 25mm road tyre to full pressure! If a long way from home I now take 2 pumps, I did have what appeared to be a nice, solid Bontranger pump crack on me, luckily only 5 miles from home so walkable.

Regarding sealing on the bike I use a ring of old inner tube around the head of the Topeak, it helps but in a real wet long ride water still seems to find it's way into the pump when frame mounted.

Tempted to try a Lezyne pump for the bike, I have one of their track pumps for the shed and it is very nice indeed, though the chuck is slow to fit and as already mentioned can unscrew some valves.

The normal main road way could have hold ups so those in the know take the lane.


Those in the know are unlikely to take a lane so narrow that a cyclist and a car can't pass each other. The first time they meet another car is going to create an impasse with somebody having to reverse up.

My suggestion for any road too narrow for a car and a bicycle to pass each other is to ban cars from it. Cycling both ways and people who want to motor can find a different route!

Does anybody know if the re-surfacing on the Bramber to Shoreham part of the Downs Link has been completed yet. Could find any info on the website.

Lucky you conrad to live in such a beautiful country where you can cycle in such temperatures in mid "winter". Italy truly does have a broad range of terrains/climates. That last pic of yours rather reminds me of the beach Montalbano's house appears to front onto.

Re: Wheel recommendations for credit card touring

The best book about bicycle wheels was written by Brandt, and first published in 1981, long before to-day's deep section rims.
Brandt calculated that a radial load of 50Kg at the axle of a 36 spoke wheel would produce a maximum radial deflection of the rim of 0.15mm......you won't detect that by riding a bicycle fitted with pneumatic tyres.
When you put a steel wire under tension the wire stretches. Unless the load on the wire is approaching a load which will cause the wire to break by plastic deformation, adding (say) 1Kg to the load on the wire will produce the same amount of stretch regardless of the starting tension. In other words the relationship between load and stretch (Young's modulus)is linear, and unless spokes are under no tension at all or are failing plastically, a "slack" wheel will respond in exactly the same way to a load as a similar "tight" wheel. Properly tensioned conventional wheels have an average spoke tension in the region of 100Kg per spoke. With a 32 spoke wheel, pedaling torque increases the tension on 16 spokes, you won't be able to feel the spokes stretch as a result of the torque you apply by pedaling. The additional pedaling load is small compared with the total static tension of approximately 1600Kg on 16 spokes.
Spokes fail at the elbow by fatigue caused by the cyclical un-loading of spokes at the bottom of the wheel. When one spoke fails in a wheel, other spokes are likely to be going the same way......how soon they fail is determined by their fatigue status, not by replacing a failed spoke, unless you also stress-relieve all the spokes when you replace a broken spoke, when you may extend the life of the other spokes.
If you speak to somebody who builds a reasonable range and number of wheels, they can tell you some things about wheels.
1) a dished rear wheel is much less stiff laterally in one direction than it is in the other direction, due to the bracing angle of the spokes.
2) a wheel with a big, stiff rim is much stiffer laterally than a similar wheel with a narrow, shallow rim
3) wheels with reduced spoke count work by having a big stiff rim (which is either heavy or thin walled) and high individual spoke tension
When you push the pedal down, you want to drive the bike forwards, but there is always a tendency for the bottom bracket to flex sideways, which is resisted by the lateral stiffness of the frame and wheel. A stiff bike accelerates immediately you push the pedal.

Has anyone used the bus service? It looks good value. How are they with bikes?

There's also some lovely gated roads not on Streetview, around Skeffington

Train not Upham!!!!

Thanks. I think the Upham to Cork sounds like a good plan. We'll be travelling on Saturdays so should be none push hour also!

Once police have been alerted one of their early moves is to close this back road to all motor traffic. Otherwise being single track it very quickly becomes a very long car park. At least it leaves it free for bikes and emergency vehicles. Generally it does not carry too much traffic so is reasonable to cycle on. Mind you anything would be better than the A85.
I was once shouted at by a driver on this road, who had to wait for me to get to a passing-place (I was riding uphill) "why can't you cyclists use the cyclepaths?". My response "why don't you drivers use the motorways?". A frequent exchange for many I know but I've never had it in such a location!

I've no idea where the nearest cyclepath or motorway to Oban is!

Has anyone used one on the road side? Do they work? would they work on all wheels? Ambrosia, Ultegra, Mavic?
They were reviewed in Cycle some time ago, by CJ I think, the conclusion was that you couldn't get enough tension to be worthwhile.

I've order the Ultegra 6800 wheels - managed to get them for under £200 with free delivery and free returns

and the Grand Prix 4 seasons at £27

ordered three spare spokes, although I'm intrigued by the emergency spoke replacement - seems like a good idea if a spoke goes on the rear cassette side and you haven' got the tools - also only need to carry one per group of people, not three spokes each, and I don't have to remember tp carry the right the spoke for the wheel

Ah, that's different. My original comment was fairly tongue in cheek anyway; not sure whether I thought you or the drivers were going uphill, but I had assumed you were going in opposite directions. So now it becomes clear you were first squeezing into the side then getting off and walking to allow cars to overtake you. That seems very... generous of you! It's difficult to judge the situation without being there but I would probably have made them crawl along behind me if there was no room to overtake, until the point at which I could no longer ride it.Yes I realised it was tongue in cheek. Yes I admit I have to take my own time on a steep hill and not be "harassed" by vehicles stuck behind me. But shouldn't that Royal Mail Postman be on a bicycle too, rather than in a van?

I've made a bracket to put the bottle and the pump on the same pair of braze-ons.It would be nice if they offered at least an optional bracket that fits under a cage, I found one in a used bike place.

And it doesn't come with a bracket that fits under a bottle cage so you lose a cage (I believe the Lezyne has that issue)

Fine in good weather, but keep your expensive kit in your panniers. The weather is a killer of seals etc. It's so small it goes in my tool bag. I'm not a fan of clutter. That's what my beard is for...b
