Smile and wave!

Perhaps the children of Lindal-in-Furness have never seen a camera:

Smile and wave!

Probably not worth being flattened on the A590 for, all the same.

SRAM X7 10-Speed Rear Derailleur – why the cheap pulley bearings?

May 15, 2015

Subject says it all really.
Why do SRAM spoil a competent rear mech. with cheap and nasty bearings which go rusty if they are in the same room as a drop of water?
SRAM ought to expect bike components to get wet from time to time, I’ve had the rear mech about a month.

(31/8/2015) By way of an update, SRAM do say you can dismantle the jockey wheels, remove the black seal and add grease. It’s a lot of faffing around compared to using better-sealed bearings in the first place.

Dropper seat post and where to put the rear light.

October 27, 2014

I have just changed the seat post (and seat) on my mountain bike to a dropper seat post. I was a bit skeptical about dropper posts, but I’m a convert now. As I’m a bit of a traditionalist, I like to have a rear light on my bike.

Not attached to me.

Not attached to my bag.

Not attached to my bike helmet.

In any of these places the light may be pointing at the ground, or the sky.

I did see a post on the singletrack forums which gives a cheap solution, and there is this post on another blog which is the same idea. My version is made from plastic pipe, with two notches machined from it, and two zip ties:

The CamSports HD-S 720p – again. Updated 13/5/2014.

October 26, 2012

Update 13/5/2014:

The replacement case did not arrive, polite follow-up emails went ignored. Not a great impression to be honest. Recently I have had to retire the camera, water got in to it and (despite my best efforts to dry it out) the camera is now damaged beyond repair. I have bought a cheap camera which has a greater battery and memory capacity, although the lens and sensor have room for improvement. With cameras you usually only get what you pay for.
This is the original text published 26/10/2012:
I just wanted to say that I’m very happy because I have been able to obtain a replacement outer case for my bullet-cam.
The longer version of the story follows:
I emailed CamSports last month to ask about the possibility of obtaining a replacement case. The camera is older than the one-year manufacturer’s warranty, so I knew I’d have to pay for the part.
No reply came, and I forgot about chasing it up. Today someone from camsports.com replied back to say two things:
(a) the company had been re-organised, and they were sorry that they had just discovered my message.
(b) was I still interested in a replacement case.
So I replied back saying that I was still interested, and I also made it clear that the camera was older than one year, therefore I was happy to pay for the part.
CamSports responded by saying they would send out the part, free of charge. This is from France to the UK, so it’s a little more expensive than non-international post.

So the message here is: be patient and polite to people. Good things will happen.

The CamSports HD-S 720p – upgrading the internal memory.

July 28, 2012

In April last year I bought a CamSports HD-S 720p. It has 4Gb of memory for recording, but no external slot for a memory card as some other cameras have.
Today I have swapped the factory-fitted 4Gb micro SD card, for a new 16Gb micro SD card.
The camera seems to work fine, although I’ve not recorded enough video to exceed the file size limit in FAT32 of (4Gb minus 1 byte). I think the way I use the camera means that it is unlikely I will get near this limit.

Barrow driver fails to stop after collision with a cyclist.

December 12, 2011

http://www.youtube.com/watch?v=3G8qYF3POiU

Being realistic, the cyclist was coming down the hill a bit too quickly.
The driver did not indicate left, sadly this is far too common.
Go back and watch the video again. After the collision, follow the driver. He (or she) turns right, stops immediately, reverses back out again in to Rawlinson Street, then turns right again. This series of manoeuvres seems to suggest the driver knows a collision has occurred. After the reverse-turn, the driver sees that is a cyclist, and decides to leave the scene.

There are things I do as a cyclist to avoid this type of accident:
Approach the junction expecting to need to stop, no matter if the traffic lights are red or green.
I do not undertake the cars, I do try and make eye contact with the drivers.
If I’m turning left, I take a slow, wide line.
If I’m going straight ahead, I occupy the centre-line of the lane.
(In both cases I am fully aware that traffic is behind me. Tough. Take your turn like everyone else.)

Missing screws from the Maverick DUC 32 forks.

September 7, 2011

I returned from a bike ride recently and noticed a screw was missing from one the fork leg guards. This was obvious because the leg guard was at the two o’clock position, not pointing straight up to 12 o’clock. The service manual can be downloaded here. Item 22 on page three of the manual says "Screw Phillips Panhead 3 x 6". That’s in metric, apparently.
It is an M3 screw you need, no longer than 6mm. Commonly used in computer cases to hold DVD drives in 5.25" bays. Chances are the last DVD drive you bought had a bag of four of these screws, and you used two of them.
This photo compares the original screw, and the replacement:

Surprise undertake by plumber’s vehicle today!

April 29, 2011

I don’t know if this was a result of impatience or carelessness, but it was unexpected.

A pair of frame captures, showing the name of the company and registration plate of the vehicle:

New toy: A helmet camera.

April 25, 2011

I have treated myself to a helmet camera, and I’m impressed with the results. The camera is a CamSports HDS – 720p. It’s simple to use, small and lightweight, and comes with a generous supply of extras for attaching it to yourself, or your bike in various ways. I might even put one of the mounts in my car to record my driving.
There are now some biking videos on my youtube ‘channel’. Naturally I will tend to publish down-hill runs, because watching someone pedal up-hill for thirty to sixty minutes is boring. Even if it’s “Uphill Dave” pedalling. Which I’m not.
I will observe the wide angle lens does tend to make everything appear to be further away than it actually is, this makes motion appear to be slower than it actually is.
If I’m cycling on a utility journey, for example, I intend to record the entire Point Of View for my ride. I expect to be deleting the recording (ideally) 1000 times out of 1000, but I’ll settle for 999. If I’m cycling on the public highway, and I record someone doing something careless or dangerous then I will publish the video. If this guy can do it, so can I.

The footbridge at Little Langdale is now replaced.

October 6, 2010

On September 18th I reported that the footbridge at Little Langdale was closed.
Having been past there tonight, I was impressed to find a brand new timber footbridge there. Well done Cumbria County Council. Double plus good.
A learned friend and biker informs me that the bridge is almost certainly made of Kwila.
He describes Kwila as very hard, and difficult to machine as it contains a natural abrasive which blunts tools very quickly. The bridge doesn’t seem to have a sub-structure, but appears to be entirely timber and self-supporting. It also lacks a central pier, as it is only supported at each end.
