It shouldn't be this hard.





Update: A very nice sergeant from Tasmania Police has been in touch and has spoken to the driver concerned. A good result.

On March 6 last year I was out riding with a friend when a driver drew level with me, suddenly floored his accelerator and fishtailed left and right, his tires squealing. He repeated the performance when he passed my riding companion who was perhaps 30m up the street. On both occasions he missed us by no more than with width of a set of handlebars. Not far up the road the driver pulled into his property. He yelled abuse as we passed. He was unsteady on his feet and appeared to be drunk.

What was particularly strange about this incident was it with that we both immediately recognised the driver as a man who was on bail while awaiting a hearing for serious driving offences. We continue on our ride and and called police about 20 minutes later. As the only officer in the area were busy we agreed to make report at the police station in Huonville the following day. An officer made a cursory show of taking the details of our complaint on a scrap of paper. We told him we believed we knew who the driver and gave him a brief outline of the incident and the vehicle's numberplate details. The officer asked us what action we would like taken and said he would be back in touch to take our statements. 

That was 10 months ago. Neither of us have anything since despite a couple of calls and going to the police station a couple of times each. In the meantime the driver we believe was responsible has been found guilty and sentenced on charges relating to an incident in which a cyclist was killed. I can't say I've ever had much faith that the police would take our report very seriously - in fact I wrote out my own statement later the following die so I could recall the details if required. 

Three weeks ago, a motorist on Sandy Bay Road in Hobart - in a hurry to get to the beach - passed within about 10cm of my right elbow as he impatiently sped through a gap between a parked car and median strip in which I happen to be cycling. I had a GoPro mounted under my saddle which was turned on at the time and caught the incident. (The clip is at the top of this post.) The following day I reported that incident to police and the familiar pattern repeated itself. Again the report was taken on a scrap of paper, not an official form or notepad or on a computer. My offer of the video evidence on a memory stick was declined. Again I have heard nothing from the police since I made the report.

Two incidents don't necessarily paint a complete picture of how Tasmania Police respond incidents involving cyclists, but I can't help but think the complete lack of interest shown in each case reflects a pattern of unfortunate indifference. In a week in which the state's peak motorcycle body called for cyclists to be forced to carry number plates one wonders what earthly difference that would make as a safety measure when nobody seems to be particularly interested in enforcing the safety measures we have now. 

There are a lot of things that need to change about the law and how it protects vulnerable road users. Since we're discouraged from taking the law into our own hands, getting the police to do their job would be fine start.

Sanity in gearing

I'm back in the saddle again, happily. I've managed to churn out 160km since whining about being slack on Saturday. The extra miles have me feeling good on the bike and have really boosted my confidence for this weekend's trial. I've finally fallen in with a bunch of local riders of about my speed, ability and shockingly casual attitude, which is ironic because I'm leaving town in four weeks. Hopefully there will be a similar mob in Hobart.

Spending more time in the saddle watching the scenery go by has me pondering a few things. Why is the cable routing on Shimano SPD drop bar shifters so inelegant? Couldn't they have run the cables along the handlebars like Campagnolo do instead of leaving them hanging out in the wind? Would I be happier with down tube friction shifters just to make thing prettier? The big issues clearly occupy my mind.

Anyway, I'm working on a cunning plan to upgrade my crankset so I can use the old gear to build up a road bike for Mrs Surly Dave. (She gets a road bike, I get a new crankset, we're all winners). Being someone to completely over-analyse everything, I've hit the spreadsheets. I ride at an average speed between 19km/h and 23km/h. Now and again with a tailwind I'll nudge towards 30km/h. Up hills I'm slower - 10 to 15km/h depending on the hill. So I need gears which help me ride in that range.

OK, so here's where things get technical. I generally pedal with a cadence between 70 and 90 revolutions per minute. Let's call it 80 for the sake of the argument. My gearing ranges from 109 inches down to 29, or to put it another way, I travel between of 9.2m to 2.3m per pedal revolution. With a 52/39/30 triple crankset and a 12-27 cluster, my bike is set up to propel me at speeds of between 13km/h and 50km/h. The trouble is, I seldom go this fast. I very, very rarely use my top chainring. (The yellow highlights on the gear chart below show the gears would use at normal speeds, some are duplicates. Click to make big).

It works out that about eight of the gears on my 30-speed are never used except for when I'm in a hurry on long downhill. This is, of course, not counting the duplicates and the gears which can't be used because of chainline issues. Being charitable, that takes out another 12 combinations. So on a 30 speed bike, I've got about ten useful gears.

So it turns out that getting whole bunch more gears doesn't deliver anything more for the average cyclist except added weight and complexity. Wow, big surprise!

But assuming for a moment I'm a typical, or even sane, cyclist who seldom exceeds 30km/what would be the ideal setup for me? (I don't want to get rid of the lower gears, they come in handy for getting up hills.) It turns out to be 44/32 front chainrings with a 12-27 ten speed rear cluster. That gives me 92 down to 29 gear inches and an effective speed range of between 40km/h and 12/km/h at 80 rpm. I'd guess that such a setup would cover just about every casual and recreational cyclist in the world except those lucky few who have a downhill commute with a tailwind home.

But do you reckon you can buy such a setup? No way. Not even in the compact double cranksets so popular of late. Why not? Presumably because when you ride the Tour De France, you need a 53 tooth front chainring to give you a huge 120-something inch top gear to charge down mountain passes and in the sprints. It's madness, madness I say.

The 'so funny it's true' department

The good lord knows we could all do with a laugh, this 'typical anti-cyclist' letter is from aus.bicycle:

Dear Sir
When so-called asylum seekers get free haircuts for their swans isn't it time someone did something about cyclists?
Yesterday I saw a completely invisible cyclist riding backwards with no lights or helmet, drunk, on fire, juggling bubonic plague vials as laser death rays shot out of his lights and blinded passers-by. Dozens lay slain. And they don't pay road tax.
Yours etc
Colin Apron.
