January 25th – There’s been a bit of a running debate lately amongst friends and family about just how much one should clean a bike in winter. I must admit, I’m from the ‘Only clean when the crud is ~25% of the total weight of the bike’ school, but others differ.

Visiting a client this afternoon, I checked out the bikes parked in their bike rack. This clearly well-used semi-hybrid has a fairly clean, well-lubed chain, but oh – the caked mud on that front mech is crossing a line.

That thing really needs some mudguards – all the mud from the back wheel that isn’t doing a skunk-strip on the rider’s jacket is being dumped on the chain and front mech.

November 26th – Spotted in a works bike rack, this fine steed. A very decent bike, with very curious panniers on the front of the crossbar. They seem to be holding cells for the front light, but I must confess I don’t understand how they’re comfortable to ride with. If those were on my bike, I’d keep banging them with my knees.

Still, bikes are very individual and we all have different solutions for luggage and general carrying needs. Studying other people’s bikes is endlessly fascinating.

November 25th – Another good one for Bob’s big book of bizarre mechanical failures. A few weeks ago I bought new cycling shoes and fitted new SPD cleats – the small pieces of metal that lock into the pedals for better engagement in place of toe clips – as is normal. I nipped up the screws, and gradually adjusted them for best cleat position.

Riding to work this morning, it felt like my left side cleat was clogged with mud or debris, and I had difficulty engaging and disengaging. As I went on it became more and more tricky. Arriving, I inspected the leat and found it had come loose and was rattling freely.

I have never had this happen before and am very surprised.Potentially very dangerous, I’m glad I found it trying to clip in and not out.

If you use lipless pedals, check your cleats for tightness today.

November 13th – The bicycles of Brum are becoming more and more diverse. In the city for an afternoon, there were a variety of beaters, bike shaped objects, fixes, singles and other steeds clearly with the primary purpose of utility.

The KTM city bike was interesting, with one of the most ingenious frame locks I’ve ever seen, but the ladies Raleigh was nice too, showing some interesting design. Bit concerned about the interaction between the rear wheel and back brake cable though.

The ladies BSO with broken front brake parked without a lock was scary too – and the brake disc equipped front wheel with no callipers on the bike told it’s own story.

That red fixie was someone’s pride and joy, too.

April 25th – A recovery day, mainly resting and pottering around attending to mechanical issues with the bikes. Long-term readers will remember my bizarre crank failure last spring, and at the time I suggested I’d never see it again: well, I was wrong. 

This is an identical Lasco crank from my other bike. There are clear cracks growing either side of the pedal mount bore. Thankfully, I had a spare so changed it over on discovery, hopefully forestalling an unexpected failure.

I‘m not sure if this is a poor design, manufacturing failure or a sign that I should lose some weight…

March 5th – Never let it be said that I do not consider cycling a broad church; from the moment any of us owns a bike, we make it our own, unique. We confer upon it our patina, our personality and our individual stamp. We personalise, adjust the fit, add our own accoutrements, dial it in until it fits.

The handle bar area – christened by the great Bike Snob of New York blog as The Cockpit, is probably one of the most individual bits of any steed. I have a personal arrangement of controls, add-ons and positions on my rides that is unique, comfy and tried and tested.

However, wandering through Birmingham city centre on a dull  Thursday afternoon, even this easy-going freewheeler found a cockpit that confounded him.

The bars. The brakes. The light pointing at the ground. I’m hoping the owner has swivelled the bars up as a theft prevention technique, but I’m not convinced.

Coo, gosh! As Molesworth might say.

November 7th – This is annoying. Just about every bike wheel has spokes of some sort, and their job is critical and load-bearing. As you ride, the spokes on the bottom of the wheel are in compression, and the ones at the top in tension, and as the wheel spins, the spokes are alternately pushed and pulled.

The do a lot of work considering they’re just 2mm diameter bits of stainless steel wire.

I carry lots of weight on my commuting bike – anything up to 20 kilos, and together with my resplendent girth, the wheels come under some stress, particularly on the pothole-strewn backroads of Walsall.

On Thursday, the bike felt odd on the back end. An inspection showed me that three spokes had broken, which need to be replaced. That’s a pig of a job, especially as they have broken at the rim end, which means removing the tyre and rim tape and replacing the nipples.

Today, I procured replacements and hoped to do the job when I got in – but it was far too wet and miserable.

I don’t know why the spokes failed; probably just excess weight and fatigue. But I’ve now lost trust in that wheel and wonder what else it has in store for me…

October 7th – An odd bike spotted in a rack near work. It was so odd, I had to take a closer look.

It’s a Kettler city bike. Kettler are, I believe, a German brand with an office in Redditch selling into the UK. It’s a large bike, and looks very heavy indeed. Dynamo lights powered by a bottle, rather than hub generator and rim brakes – the rear an unusual crossover cantilever design mounter under the chainstays – mark this bike out as being a cheap model. More expensive steeds of this type would have hub brakes.

The bike clearly needs some love – the chain was as dry as old bones and red rusty, as were many of the components. I’m tempted to pop back just to lube the chain. It must squeak like hell in use.

An unusual thing, for sure…

October 1st – Spotted this bike on the train today. It’s a Cannondale, a brand I’m not keen on, mainly for their curious approach to design and resolute defiance of industry standards.

I snatched these images on the phone, as the owner was clearly happy with his new steed. The bike has an interesting feature – ‘Headshok’ suspension. Rather than conventional front systems, where both fork legs travel together and work in tandem,  this system is at the fork crown, and much of the mechanism – dampers etc. – is in the head-tube and between crown and fork.

Initially appealing, it means all the load in work is on one member, rather than two; the system is utterly proprietary, and requires frequent, expensive, short milage interval services. Finally, you only have to look at them funny and they stop working.

There are avid Cannondale fans out there, and many love Headshok. My experience was that it was a whole bag of hurt.

I wish my fellow cyclist all the best of luck with his new bike. I think he’ll need it.

August 14th – The day was mad. Starting with a great deal of nervous anticipation, the wheels of the day ground slowly at first, then became frenzied. I found myself via a convoluted route in Brum at rush hour, looking for food and a cup of tea. Crossing the Cathedral Square – Pigeon Park to locals – I spotted this bike rack. Using it were the spectrum of bike users; a modern roadie’s bike, an achingly hip single speed (set to freewheel side, not fixed as per usual), and finally, a wee folder. 

Nice to see so many bikes in Birmingham these days – and such a variety too.
