The weather has a significant impact on life of a cyclist. Knowing how to dealt with is critical to safe and enjoyable cycling

Marv’s Law of Bicycle Punctures

Carrying on from previous posts about irritating punctures, I’ve compiled a list of clauses which I’m now proposing as my law describing the likelihood of getting a puncture.  Some people may think I’m getting a head of myself here but, sad to say I’m basing this on empirical observations of my own stupidity.

Clause (i) If you are going to get a puncture, it will be at most inconvenient time, when you are late for work, a dinner date or an important and you will not have brought a spare tube or puncture kit.

Clause (ii) It is inevitable that you will have more punctures on your back wheel, as this carries your weight.  Consequently, if you are like me, heavier you will have more punctures.

Clause (iii) It more likely that you will have rear puncture when you haven’t cleaned your rear running gear and/or are wearing new clothing.  Grease will find its way into places and clothing that can’t be easily cleaned.

Clause (iv) It is more likely that you will get a puncture when it rains as more debris is washed onto the roads and wet tyres are more susceptible to damage.

Clause (v) It is more likely that you will get a puncture and then have the weather turn bad with heavy showers making your machine’s parts that much harder to handle.

Clause (vi) It is more likely that you will get a puncture when you are riding alone when there is no one to help you.

Clause (vii) It is more likely that you will get a puncture, if you are stupid enough to boast about never getting one.  This is hubris which greatly angers your fellow cyclists and Velos the Greek god of bicycling. You will be smited by his wrath 🙂

 

Making the best of Melbourne’s windy days

Riding into the wind

The Lead Out

If you are like me, you dread riding into a howling headwind.  Whilst the tougher and dare I say fitter members of the Melbourne cycling fraternity might say ‘Harden up’, the reality is learning to cycle intelligently in the wind is a better option.  This post briefly describes how someone new to cycling can adjust to cycling in windy conditions, either alone or o as part of a group.

The Breakaway

Bottom line: Plan your route and check out http://www.bom.gov.au/marine/wind.shtml, to see the most recent wind forecast.

The Peloton

There are three basic conditions that the cyclist must deal with:

Headwind  Headwind Where the wind is predominately in your face. Using the ‘clock analogy’, the wind is somewhere between 11.00 am and 1.00 pm.
Crosswind Crosswind Where the wind is coming from either your left or right and catching your side profile. Using the Clock analogy, the wind  is either blowing from 9.00 to 11.00 am or 1.00 to 3.00 pm
Tailwind  Tailwind Where the wind is directly assisting you from behind.  The wind is behind you somewhere between 3.00 pm and 9.00 am.

Riding into a headwind

Rise to the challenge use headwinds as a means to build conditioning.  However if that’s not your thing, here’s a few tips for working into the wind.

Cycling by yourself  Your best tactic is tuck down into an aero position where you are seeking to minimize the vertical area presented to the wind, thus reducing drag.  Think racing car profile versus that of a bus.  Tuck your elbows in and place your hands on the drop part of the handle bars.  Try to align your head and torso with top bar of the frame.  If you are like me and have a bad back and tight hamstrings, try to duck down as best you can.  Word of warning, don’t fall in the trap of road watching, or you’ll run up the back of someone or collect an obstacle eg street furniture, pedestrian or as in my case a parked car….ouch.
Cycling with group  Your best tactic is to draft  the rider in front of you and let them create a pocket of broken air that you can slipstream into.  Its worth watching tour coverage of time trials or track cycling events to see how the pros do this.  Most columns I’ve read about this seem to suggest being no further than a bike length back to achieve the most benefit.  Word of warning, don’t overlap wheels with rider in front, lest risking a very angry conversation post-crash

Riding in crosswinds

I’ve always found these the toughest to ride in, particularly where the wind is blowing from 10 o’clock to 11 o’clock and pushing your line out into either the rest of cycling group or oncoming traffic.

Cycling by yourself Again, there’s not much you can do other tuck down into an aero position or plan a route that has some cover to break up the wind up.  On really windy days I’ve done laps of Albert Park Lake to break up the ride.
Cycling in Group Pelotons tend to arrange themselves into an angled formation called an echelon.  The leader bears the brunt of the wind and the rest of the group try to draft in the wind shadow created by the bike/body profile.  The formation resembles a diagonal line pointing away from the dominant direction of the wind. Last year, I saw the peloton bunch up so closely into the crosswind, that the formation looked like a gigantic elongated teardrop.  This made me wonder if this isn’t the preferred pattern for very large groups of competing teams.

Riding with a tailwind

Everyone’s favourite wind and makes you the rider feel like a tour champion, for as long as it lasts.

Cycling by yourself  Plan your route so that you return home with a tailwind.  There is nothing worse than a long slog home.  Keep an eye on the weather forecast to determine whether a change will come through and whether the direction may change.  I look at the BOM wind forecast (see above) to check strength and direction.
Cycling in a group  If you are racing, using a tailwind is a perfect time to launch an attack. Up the cadence, Tora! Tora! Tora!.  But like all good things, favourable winds will end.  Make sure you have left something in the ‘tank’, lest be left  behind.  Also don’t take unnecessary risks with newly found speed, going faster means landing harder in a crash.

Riding… not Singing or Crashing… in the Rain

Advice for Chris Froome 🙂 and Team Sky

I wrote this a few weeks before the Tour de France but its seems appropriate.

The Lead Out

Here’s a few pointers for riding around in the rain in Melbourne.  Clearly the smartest thing you can do as a cyclist in Melbourne is plan your route.  Pick the a route that provides the safest road conditions. Maximise your use of off-road and on road bicycle lanes, and roads that have low traffic volumes and speeds.  Melbourne City council has a pretty good map that you can download from here:

The Breakaway

I’ll say it again, look at http://www.bom.gov.au/vic/forecasts/melbourne.shtml, before planning your ride.  Its free and may save your life.  If you find yourself riding in poor conditions, play it safe, try to stay off the road and make yourself as visible as possible.

The Peloton

  • Clip on and switch on some decent front and rear lights.  Anything above 200 lumens that has a ‘strobe’ mode is ideal for the front.  Similarly 90-120 lumens, with strobe is ideal for the your rear
  • Stay on commuter paths.  Typically be less congested and greatly reduce the risk of you becoming a hood ornament eg Chris Froome 😉
  • Try to stay upright and steer with your arms rather than leaning into corners with your hips.
  • Take corners slower – wet riding surfaces reduce traction between the tyres and the surface.
  • Avoid hazards such as potholes and storm water grates.  Watch out for doors on parked cars.  The chances are the driver has been thinking more about the rain, than a cyclist approaching from behind.
  • Wear bright waterproof clothing – I have bright yellow gortex jacket with reflective patches that is highly visible and breathable.  Something like this is ideal for daily commuting if you have a few spare dollars.
  • Carry a spare tube, instead of a patching kit.  I’ve found trying to patch a wet inner tube almost impossible on rainy days.
  • If you are on your road bike, decrease the pressure in your tires, say 5 to 10 psi lower than your usual setting, to improve traction.
  • Try to avoid slick spots – pay attention  to painted street surfaces, metal drain covers,
  • Try to cross tram and rail lines at 90 degrees or close to, to minimise contact.  This is a particularly nasty hazard on wet Melbourne days.
  • Double the amount of time you use to brake to stop.  Locking up will lead to you either spinning out or going over the handle bars.  Do a few test ‘brakes’ at the start of your ride to feel out what your new threshold should be.
