And don't get dope tested.

The newer ones have the hole pre-filled. When I had the problem, the thing went completely dead - no lights, nothing. If the cadence light is working (does it transmit cadence to the 705?), the problem might be that the wired joining the speed switch to the transmitter has broken. A couple of people have reported this problem

I'll be there in Cresta Wheelers kit, on a white(ish) Look.

I've also used them for corporate and club kit. They're connected to Anatomic in some way.

I think you should change your username.

You can swap front to back, but never swap the other way - it's dangerous. Here's why: http://sheldonbrown.com/tire-rotation.html

On the subject of ducks...

Well, the duck has Wikipedia cred. I personally would have used rabbits. Fearsome creatures, rabbits.

If it looks like a duck and quacks like a duck... http://www.youtube.com/watch?v=chnzvcsm-l0

Power readings are a nice to have, but you can get a very good estimate of power just using speed and a speed-power curve for the trainer. Check out Trainerroad.com and the SportTracks trainer plug-in.

Same reason we pay 50% more for imported clothing: to prop up an inefficient local industry that would die if exposed to a free market.

He could probably also leave it constantly running during the day, with the aircon on, and still pay less in petrol per month.

Email them and ask Email them and ask. They've usually responded timeously to my queries

I don't think so, it looks like he's flipped the RD around too.

Where did you find it and which model? The only 1500 lumen USB Serfas I've found is the TSL-1500 that goes for about R3k.

I've stopped all riding since last week and I'll be cutting down on sleep this week. I like to call it the thesis taper.

Isn't this offset by the fact that carbon fibre is much stiffer than aluminium, which increases the overall amount of vibration transmitted?

Very easy. You just open the cap and swap the battery. It uses an easy to find CR2032 battery too. If you've got an iPod Touch, iPad or iPhone and an ANT+ dongle or bike case you can use the Qalvin app to completely calibrate the Quarq yourself (i.e. check the slope and change if necessary). http://www.quarq.com/qalvin http://youtu.be/4IZL3QXtYv0

Murphy rules again. I wrote this whole explanation and then found a site that explains it better: http://www.ctc.org.u...aspx?TabID=3946 It seems that, within brands, shifting correspond roughly to my scenario 2.

The shifter is usually unchanged, but the FD cage width usually changes with the speed due to different change widths. My experience is that I got slow front shifting using a 9sp FD with a 10sp chain, while I get good shifting but a lot of chain rub with an 11sp FD and 10sp chain.

I don't think it's quite as simple as that. To get perfectly indexed shifting, every click of the shifter needs to move the RD by the cassette spacing amount e.g. one click moves it 4.55mm for Campag 9 speed vs. 4.12mm for 10sp. The movement per click is determined by the shifter pull ratio (the amount of cable the shifter pulls in or releases per click) and the derailleur throw ratio (the amount the RD moves for every mm of cable movement). There are three scenarios for mixing components: 1.) Shifters have the same pull ratio, different derailleur throws. As an example, both the 9sp and 10sp shifter could move 1mm of cable per click. The 9sp RD then moves 4.55mm per 1mm while the 10sp moves 4.12mm per 1mm. In this case, you would need to match the RD speed to the cassette speed. 9sp shifter with 10sp RD would give 9 clicks and you'd have to set the limit screws to avoid the top or bottom sprocket. 10sp shifter with 9sp RD would give 10 clicks and you'd set the limit screws to stop it overshifting at one end (effectively cancelling a click). 2.) Shifters have the different pull ratio, same derailleur throws. The 9sp shifter could move 0.91mm of cable per click, while the 10sp moves 0.824mm. Both shifters then move 5mm per 1mm of cable pull. In this case, you would need to match the shifter speed to the cassette speed. The derailleurs are essentially identical (the jockey wheels might be different). 3.) Shifters have different pull ratios and throws. The 9sp shifter could pull 1mm and the RD moves 4.55mm, while the 10sp pulls .824mm and moves 5mm/mm. In this case, whether you get perfect shifting would depend on the exact ratios. It's possible to get a functional drive train with mixed components, but there's a chance that you will get excess noise and possibly skipping at the ends of the cassette.

Do they realise that Quarq is a SRAM product and comes in through, and is supported by, the SRAM supply chain? Edit: The support I've received to my queries both directly from Quarq in the US and from CCS locally has been good. If something goes wrong with the electronics, it would probably have to be sent overseas for repair. Likewise for SRM, P2M and possibly Powertap (I know they can service the hub mechanicals, but I'm not sure how much electronic repair they can do).

You need to find where the GTC database file is stored. ONce you've done that, open ST and go to Import, select the Import from Folder Icon, change the file type to GTC Database and select the GTC DB. It will read it and present a list of all the rides in the file and you can choose which ones to import. You may need to manually select some of the options for each ride. The After Import plugin could also be useful.
