March 14th – My experiment with Specialized Armadillo tyres is now over.

I will not be buying another set.

On my favourite steed, I have tyre clearance issues with the mudguards, so wanting to return to the softer, more forgiving ride of a 28mm tyre over the usual 25s, last September when tyre replacement was needed, I got a pair of Specialised Armadillo tyres I’d heard were very good – apparently nearly as resilient as Martathon Plus which I normally use, at a lower profile. 

People ho liked them recommended them with an almost religious zeal.

My initial feeling was that the tyre were not as tough, but they bedded in and proved very puncture resistant, which surprised me. My issue was that for a tyre described as ‘all condition’ their grip was sketchy at best in even moderate rain and useless on even slight ice, as two offs and various skids in the winter had proven.

The compound seemed very hard and they tyres were noisy when rolling.

Leaving work this evening, I flatted on the rear. examination of the tyre revealed the surface had totally delaminated from the inner lining, and was shredding. Within five months.

I’ve popped Schwalbe Marathon Plus 28mm back on. The quiet and feel is heavenly. Stick with what you know, folks…

February 28th – After some grim weather over the last few days, I thought I’d seek out a weather app for the Edge, the Garmin GPS based bike computer I use. I’ve tried Accuweather, and it’s really rather good.

Accuweather loads via the Garmin IQ App Store, and uses a paired iPhone or similar to access internet weather data; it then gives what I’ve found to be fairly accurate predictions of wind and precipitin for the next two hours. It’s in an easy to read format, and if free of charge.

Being a widget, it’s accessed by swiping sideways from the pull down status screen, which had me fooled for a bit. It only loads data when accessed, so it’s power and phone plan friendly to boot.

It accurately predicted the rain that dappled the screen…

February 23rd – Back to brakes. This has really caught my attention, sorry.

Following the brake trouble I’ve talked about where pads suddenly lose effectiveness in my hydraulic disc brakes, I’ve decided to try alternatives to the stock Shimano pads. 

I wasn’t expecting them to be any good – I was wrong.

I’ve tried the Kool-Stop first. This company makes a very highly regarded road brake block, and I was interested to see how that translated. After initial disappointment, I’m actually quite impressed.

These resin pads are described as having a ‘rotor saving compound’, which usually means they’re soft and not too effective. My fears seemed to be confirmed on the first two or three days of use, when stopping power was poor and the brakes noisy. 

I then rode in the rain. This appeared to bed the pads in and they’re now every bit as good as manufacturer originals in use. They aren’t quite as snatchy, which is good, to be honest, but they do bite when demanded.

The question is, how long will they last? We shall see. But my initial feeling is that although they took an age to bed in, they’re great pads.

February 18th – Brakes. Can’t keep stopping like this…

Thanks for all the suggestions for answers to the sudden loss of braking power issue. The disc is not greasy, the pads are dry and the disc is only 0.06mm down from new thickness – although that one really did make me think, so cheers for the suggestion.

I put in a set of Shimano pads. They worked fine once bedded in, without cleaning the disc. The old ones look glazed, and seems to be a grumble in online bike forums. 

I’ve decided to trial some aftermarket alternative pads to see how they fare in comparison – the red ones are Kool Stop, who are famed for old-style brake blocks, and the other set, with separate heatsinks are from Uberbike. The Kool Stops are at the pricey end of the market, the others, cheap. The interesting thing about the Uberbike ones is they come in synthetic, metal and semi-metal flavours, and you can buy the pad separate to the sink, so they’re cheaper.

Got the Kool Stops in for now. I’ll report back. Again, thanks for all the advice.

February 5th – Long exposure experiments I’m not entirely happy with, taken from the A5 bypass flyover at Jerry’s Lane, Packington and the Alan Woollatt bridge over the A38 at Thickbroom.

For some reason these aren’t as sharp as my earlier experiments and I’m not sure why. The wiggle of the road as it winds up Rock Hill was also not as evident as I would have hoped.

I need more practice, and maybe to read a manual or two…

February 3rd – Also on the square, the tell-tale sign of a secondhand steed.

This road bike – a Carrera (Halfords own band) low end job – has been clearly bought by someone who’s a wee bit too big for it. The saddle is so high as to make the geometry look unsettlingly wrong, and the steerer – the fork tube the stem and handlebars mount from has been extended by a ‘suicide’ riser. This is a device to increase the height of the bars relying on clamps to keep it secure. 

Often the clamps slip or come loose, hence the nickname.

Finally, the flat bars are far from original.

People, buy a bike that fits, even secondhand. It’s a lot safer and comfier in the long run.

January 3rd – I had to ip out to Screwfix at sunset, so again hopped on the canal. Nothing as interesting as the Goosanders, sadly, and having forgotten the camera, I chanced my arm with the phone at what was a pretty nice sunset.

Cameras on phones are getting better and better, despite the obvious limitations. I’m quite pleased with this.

December 28th – Where the cycle route NCN 5 leaves the canal at Yew Tree, just north of Rushall Junction, the path is dark and unlit – so a solution has been found.

There are little white LED solar cats eyes marking the centre of the trail in the darkness. They’re really effective.

What a clever idea…

December 12th – On the way back into Brownhills, the air was a little clearer, so I stopped on Anchor Bridge for a classic nighttime Brownhills photo.

As well as playing about with aperture settings of late, I’ve discovered exposure compensation. Must say I think the darker image is the better of the two.

One day I must read up on what all these adjustments actually do…
