Bike Forums - Addiction LXXVIII

was checking out pmc last night to and I saw handle bar power meters. Way cheaper than the cranks for obvious reasons, but is the information provided any good? 200 dollars sounds a lot better than 1200.

I’m interested if they get around to rigging it up so I can use it with a real power meter to evaluate position.

@Heathpack did a lot of aerotesting using that exact method. Well... The indoor velodrome method, anyway. Constant repeatable power, using a real power meter, and an aero/fit expert.

I did the Alphamantis version of aerotesting with my fitter, who works out of the velodrome in Carson, CA. Due to technical issues with the venue we had to do the testing twice.

His outdoor testing uses the pitot tube but I haven't done that type of testing.

You missed a step. Heed it, then do the rest.

200 dollars worth of trash has been covered ad nauseum. As WhyFi states, save your bucks for a real power meter, because there really are no majik ones out there.

This is why I don't much care for Stages....

To quote from another forum member:

At 250w

Stages gen 2 175mm for gravel bike: 250w
Stages gen 2 165mm for TT/road: 220w
Kickr: 248w

You would some strict control over environmental conditions, but maybe if you had access to an indoor velodrome it could work?

That's exactly what I was referring to. RChung could tell you all about it, I'm sure, but there are also some CyclingTips podcasts on the subject.

That sight would've scared the bejeezus out of me. My flight response would have been on high alert, just short of the GTFO mark.

My first hikes around the mountain were super ashy/dusty, being well into the blast zone seemed like being on the moon. Nowadays there is quite a bit of ground cover established and baby trees popping up all the time. Some of the first trees to emerge from the ash are getting pretty tall by now. I should see if I have more pics from my 2015 hike, here's the two I could find...

Were they the, um . . . . . ash trees?

Yes, that's true. I got one a few years back - I got used to having decent power data while riding the trainer, and couldn't find a combination of pedal/crank that I liked for my outdoor bike. It was pretty cheap, so I got one. Once the novelty of the thing wore off, I sort of stopped using it. I recall that it would shut itself off if I stopped for a break, and that was annoying as well.

It is still there on the bike, and still paired to the Elemnt, but I don't bother to charge it, and it probably needs re-calibration. I have this vague recollection that it not only had a pitot tube, but also an accelerometer. It needs to be paired with a speed sensor. DC Rainmaker did all sorts of side-by-side tests - the accuracy wasn't as bad as you might think.

It's a rough season for carafes I guess :(

Just dropped off the wheels at a nearby shop for sealant. Pretty busy. There were three people outside waiting to pick up. Happy for them.

I can just hear the whining, weeping and wailing now . . . . "oh that Lance Armstrong, he's such a terrible person". smh Get a life, get over it already.

I wonder if signing up for a 6hr race in October is overly optimistic...

For the ball sports fans, they're also doing stories on baseball's biggest cheaters, Sammy Sosa and Mark McGuire.

I just missed out on a wheelset - some Mavics laced to Chris King hubs, rotors and cassette included for $50. I messaged 8 mins after post. Just not fast enough :(

My brother printed it off last night and I swung by his office today -

The bushing was a little tight and sat a little proud, but a light shaving with a chisel took care of it.
