Cadence and speed sensors

To get the ibike's trainer mode going I needed to add these rear-wheel and crank sensors. Makes sense. I chose a power output map that looked close to my Elite trainer and let it rip. Guess what - it works!

The ibike needs a 'trainer mode key' download, too, but that's pretty simple. The ibike software accepts the key on your PC and the ibike head unit is unlocked via USB connection. Bingo, new feature set.

Note the crank-mounted cadence magnet, too.

Finally - my ibike goes wireless

OK, so I ride a bike. Big deal - so do you, eh?

I have ridden bikes since about 1972 or so and have always used some method of calculating distance ridden, be it via a mechanical or electrical add-on or by simply estimating distance from a map. Electronic methods improved markedly from around 1980 and quickly became a fairly universal way to accurately measure distance, speed and some environmental variables like temperature. When heart rate monitors took off in the 1990s that became another useful data source for the bike racer or exercise enthusiast. More recently the ibike has put power measurement closer to a price point where serious club racers find it hard to say 'no'.

And now - finally! - here is my new wireless ibike mount. So I have ditched wires - another 'big deal', you say? But I have also gained a few other tricks in the process, like an inbuilt HRM, a cadence sensor and the ability to estimate Watts expended whilst riding on the indoor trainer. It makes my indoor training more quantifiable, more scientific (hopefully) and probably more fun.

Kohl was perhaps too good to be true

Hindsight is a wonderful thing. Perhaps we should have queried a revitalised Kohl, riding better than ever before, grabbing mountain points and securing a fine 3rd overall. Perhaps riding 2 or 3, or even 5 places better than he should have been. OTOH he had previously shown promise. Maybe, just maybe, it's a mistake.

Bernhard Kohl of Gerolsteiner tested non-negative for CERA, French sports paper L'Equipe reported Monday. The French anti-doping agency AFLD had tested Kohl's blood samples. Kohl finished third in the Tour de France this summer and won the climber's jersey.

Well who gets 3rd now? Who takes the spotted jersey for 2008, after all?

Live on the web: Armstrong's blood profile

Just what we all wanted to see, Web2.0 at its very best: Lance Armstrong's blood tests on the web. Catlin said that the actual program is still taking shape. "[Lance] has agreed to a couple of a few very fundamental points. One is his data, like T/E ratio and all that kind of stuff that a doping control is allowed to do will be on the web, so you can see it. 'Ah, your T/E ration changed today, what happened?' Like to see if he is taking EPO – all the actors to make it a very public campaign."

What about this enhancement to the website itself - some sliding controls that change the blood values, with respectively new maximum values for Wattage and VO2 max as you dial up the changes. And how about a new estimated time up L'Alpe d'Huez at those values... just so we can assess for ourselves what difference it makes to have higher haematocrit, for example.

King Contador cruising. Why am I uneasy?

I have that queasy, uneasy feeling again. The Lance A. comeback. His protege Contador winning 2 Grand Tours in a year, 3 in under 2 years; one with little preparation, straight off the beach. And Astana, back in the thick of things, loaded with talent.

25-year-old Alberto Contador carved his name into the annals of cycling history by becoming the first Spaniard to win all three Grand Tours on Sunday in his home town of Madrid. The Astana star who had been denied his opportunity to defend his 2007 Tour de France title when the race organiser refused to invite his team had vowed to get revenge at his home Tour, and he succeeded.

If I trusted these guys - and I must admit it's a leap of faith to do so - would it be good or bad for the sport? Lots of publicity, sure, but have we really finished with the laundry here? Hopefully the blood passports are doing the job, because we need some indication of where fair is fair.

OTOH, was it ever thus? When has life been fair?

QandA beats Footy anytime

Laughing at puerile, self-indulgent Ch9 "Footy Show", outrated by laudable, watchable "QandA" on ABC. Maybe we are growing up?

Next step - a bike racing show? (Yes, I know, it's been done.)

Utterances

Checking out Utterli, an utterly post-post modern version of Utterz. Not sure where this all endz, but it's nice to watch these crazy widgetized developers fight it out for web2.0 supremacy

Just because, here's a track hub

McQuaid on Armstrong's 'cleanliness'

Pat McQuaid may wish to revise his words, or not, if they are correctly reported: "He'll probably never shut up the no-gooders but it might give him the opportunity to prove he can do it clean."

To me that suggests that Lance hasn't yet proved "he can do it clean". I'll say no more!

Lance returns: do we care?

Well it will kick up some dust, sure. Lance Armstrong's comeback is in the grand US tradition of retiring at the top yet seeking another "final" blaze of glory. Indeed it can't be easy to step out of the limelight and start a "normal" life, if cancer-survivor LA's life could ever be called normal. So a comeback - a well-planned, targeted one at that - could give LA another shot at proving whatever it is he's trying to prove. His innocence, perhaps?

He says he's clean and I take him at his word. He says it's for cancer-fighting publicity, but there must be something in it for him as well. Assuming he does come back, whatever the reasons, does he link with the cleaned-up residue that is Astana, banned from Le Tour 2008? Or does he seek a pure, clean break with the past? I hope the latter - but suspect he'll fall in with the "trusted" old Bruyneel team, irrespective. I'd like to be proven wrong on that.

Lastly, if he does join Astana and they get a berth at Le Tour (no guarantees there but probable), will he be top dog? One assumes so, but will it be the case if Contador has an edge in week 3? Contador's still young, so I suspect he'll roll over easily, but it won't necessarily be easy for him, either.

Yes, one day. Maybe tomorrow.

Anyway, for those new to addicted2wheels.com here's a summary guide.....

Where you are now is my main focus - bikes, bike racing and physiological stuff. However you could click away madly and find....
Cheers for now, Rob.

Well it was a great pump whilst it lasted. It seems to have some spring arrangement in the head that has failed... otherwise good, strong pump that could handle over 140psi... watch the snap-action clamping lever, though, it bites! (And the pin around which it rotates periodically works its way out, too.)

Mountain scenes to calm the nervous rider








Nothing quite like a mountain stage in a Grand Tour to calm a rider's nerves... if they are sitting at home watching it all on TV of course... these images are from some Le Tour 2006 pics taken by Brett Lyons. It's Col de la Croix de Fer.

Great work, CSC - maybe

And nice work Simon Gerrans: Schleck had trailed Evans by just one second going into the 15th stage, and ended the day with a seven-second lead over Bernhard Kohl, who headed home the chasing pack behind the breakaway group. The rest day has come at the right time for Evans, so don't write him off yet. Kohl was fifth over the line, and now has a one-second advantage over Evans, who has dropped to third in the overall standings. Gerrans produced a perfectly timed late surge to secure his stage win..

A great stage? Maybe. Actually I don't particularly like to see days like this. It smells like bad sportsmanship, a bit like the old US Postal 'launch' move, but not as obvious. Here we see 3 CSC guys basically gang up (it's called 'teamwork', ha ha) on one isolated guy in yellow - a typical bully-boy gang thing to do. It's great that CSC has a strong team, and that they play to win. I'm sure they are all great guys, too. There's also no law against being good, or great, or working as a team. Indeed at this level of the sport collusion like this is accepted and indeed encouraged. I just don't like to see it.

Thankfully CSC individually are weaker in ITTs - which will even things out. And sure, it's all part of the game and gripping to watch - but I personally like to see a select group of individuals fight it out, man to man (or woman to woman or whatever you prefer). It's just a bit pathetic - akin to bullying - to see 3 guys - in this case Sastre and the Schleck brothers - take turns in attacking Evans (or whoever it may be tomorrow).

OTOH it was a joy to watch Menchov attack - and what a move it was! What a shame he took that slippery bend too quick - and too tightly - and ended on the deck. To my mind it's Menchov vs Evans in this race and only the unexpected or CSC can break it up. Rest day, then back to it.

Just my opinion.

Le Tour: efforts unrewarded - yet?

I had mixed feelings about a stiff and sore Evans hanging tough in what proved a punishing but not decisive stage 10. What were Riis and CSC on about? Yes, it was impressive teamwork. Yes, they have some amazing riders and at least 2 GC contenders, but what were they expecting? To drop everyone on the flat? Or was the plan simply to dislodge Cunego and Valverde on the first climb and then keep them behind? Was that the plan? To thin the field?

Or were they hoping to hurt an injured Evans? Or all of the above? It seemed that CSC were scheming and hammering to little effect, other than exhausting Voigt and Cancellara. Sure, they got close to launching someone, but it didn't really happen. We all knew that Sastre wasn't going to get away, surely? So was the real plan to boost Schleck up the leaderboard? At least they achieved that, if little else. A puzzled Menchov saw both sides: On the climb to Hautacam CSC went on the attack with Carlos Sastre and eventually got Fränk Schleck away. "It's a little bit strange [what CSC did]," Menchov said. "Well, it's not really strange since CSC had to try. In the end it worked out well for them."

Although the rest day will help them - and everyone - recover, in essence it was a big tactical and power display for small reward - with most of the racing still ahead. They have indeed removed some threats, but will the Sastre-Schleck 1-2 punch be enough when Ricco is sitting on, waiting to pounce?

Ahhhh, crystal ball time. One Pyrennean stage to go. Ricco grabs another win. Ricco edges closer on GC. Evans lets the golden fleece go, hoping to get it back in week 3. Schleck and Menchov battle it out in the Alps. Sastre tries to get away, but is marked. Ricco gets away, grabs more time. Indeed, bring on the Alps. And that delicious, long time trial..

Le Tour turns on a crash?

I've had some "memory" pain in my right shoulder this Aussie Winter from a fall I had last year - which was on top of a much worse fall I had on the same shoulder in 1988... when I clipped the wheel of another rider who decided in an instant that the right side of the bunch was somehow better than the left. Of course I shouldn't have overlapped his wheel, but when you have momentum after coming off the slight rise and swooping right turn into Heffron Park's main straight you sometimes close up a bit as the lead riders hit the wind. So I was in the wrong place when that sudden move happened. I gather Cadel Evans faced a similar situation in yesterday's stage, unless the plastic bag in the front wheel story is actually true. Whatever caused it, Cadel will be stiff and sore in the next stage. It doesn't matter how tough you are, you still feel pain and lose some agility for a few days.

Valverde had his bad luck last week and has had time to recover. Evans may not be so lucky as he faces the Pyrennees and almost certain attacks. I won't blame him for cracking just a bit and losing time. It may be better than pushing too far and losing far more. He can afford to lose a minute or 2, but no more.

Meanwhile Ricco has lived up to expectations: Italy's Riccardo Riccò opened up the throttle to distance his rivals on the Tour de France's Col d'Aspin in a move similar to the late Marco Pantani to gain a solo win in Bagnères de Bigorre. The chase including classification favourites finished over a minute behind Riccò and included race leader Kim Kirchen (Team Columbia) and a bruised Cadel Evans (Silence-Lotto), who crashed on the decent of the Col de Peyresourde.

Oh how I wish he - or a clean Pantani - had been around when Lance was racing.

It's that time again

Everyone knows it's July, and July means Le Tour. And everyone who cares knows that Cadel Evans came 2nd last year, and as the winner isn't in the game this year that leaves Evans as the 'favourite'. However anyone who has ridden a bike for 3 consecutive weeks, no matter how far or how fast, knows that you can have one or 2 bad days at just the wrong time. You can catch a cold, or fall, or just get dropped and not get back. Although Armstrong made it look ridiculously easy to get 7 in a row, he did have bad days. He also had a great team and a great deal of luck, especially considering almost everyone he beat was doping. But it's not so simple any more. There are no dopes, hopefully, and no stand-outs either.

So after this 3-week-long lottery on wheels it could be Evans, or Valverde, or Menchov. Or we may get another Pereiro from out of the blue. Let's just hope we don't get a Landis, a Vinokourov or a Rasmussen.

Heart-rate monitors and servicing


Polar TX date_0682b
Originally uploaded by gtveloce
On a more light-hearted note, kinda, my Polar M22 is getting on a bit. It's been great - just 3 batteries in 8 years, and one new strap. Thinking of which, pictured here is the transmitter strap in question.

It's younger than the M22 itself by about 5 years, nevertheless Polar want me to read the tiny date markings anyway. I'm pretty sure the M22 battery has carked it - it "rebooted" itself once and then simply went blank a week or so later. I have no problem with Polar's agent in Australia wanting this detail, it's more the pain I am going through in getting the info to them that annoys me.

They want me to print out a form that doesn't format in Firefox. Oh joy. I have to use Internet Explorer instead, but they didn't say that until I'd filled out the form already! How about a warning at the top of the form, rather than the bottom? What about online submission of the form? Anyone at Polar Australia (called Pursuit Performance, btw) heard of the 21st Century?

Worse still, the M22 is a "best effort" repair as it is no longer supported with new parts (as against batteries and parts still in stock). Great. I'm thinking there may be some alternative options in the cycling-specific heart rate monitor business after this little annoyance. Only problem is that the Polar agent does do a good job overall. Do I stick with the devil I know?
