    Is TSS additive?

    I'm a recreational cyclist who likes numbers and data-analysis. Having a powermeter and analysing rides is fun for me, and the 'performance manager' in WKO works nicely as a motivational tool - trying to work up the TSS. But, I just wanted to point out a detail: TSS (training stress score) is...

    Wireless Powertap head-unit with wired hub?

    I have a Powertap 2.4 wireless on a nice carbon tubular. Consider getting a training wheel for indoor and rainy days. On Ebay, the older wired units are cheaper, and in particular wheels without a head unit. My question: will my head-unit work with older wired hubs? Thanks Henrik

    100W Hamstring booster - or just bad pedaling?

    Lately, I noticed that when relaunching speed (after turn, lack of focus etc), or when facing short hill / roling terrain, I noticably pull more, hence engaging the hamstring muscles (and maybe some others). This is like a 100W-200W booster for 5-30 seconds - e.g. raising from 260W to 400W...

    Is indoor trainer useless for me? Any benefits of IF<0.6 rides?

    I train too inconsistently to deserve a powermeter, but could afford one and am a number-neard by profession. This profession takes 70-80 hours a week, so I've taken the challenge to see what level of CTL I can maintain with very limited training time (currently 30 TSS/day with TSB around -30)...

    iBike Pro III and Polar CS600X - new opinions

    I know there are long threads about Polar CS600, and less long treads about iBike. But, I am interested to hear newer experiences and opinions. Since last year I have a PT2.4, and find that even without fancy targeted training etc. Just the TSS, IF and FTP tracking is a great training...

    Updating FTP from IF data - how often and details of wko?

    From what I understand, having IF over 1 (in the 1.05 to 1.2 range) for 1.5-2 hour rides means my FTP is higher than estimated. My questions are: 1) How often does it make sense to update FTP? Should it be everytime one posts an >1h30 with IF>1 ? 2) If updating frequently, it would be nice to...

    TSS when running - is WKO comparing cycling and running TSS well?

    Work, winter and shorter days limits the time I can train on the bike. I got the idea to swap some of the training to running, since it is easier to run after sun down. WKO allows to enter running workout manually, and assigns a TSS (training stress score) based on time and distance (i.e...

    Different IF and TSS for same ride - how to train 1h30

    This is nitpicking, but I was surprised by the IF and hence TSS calculated by WKO for 3 rides of my standard circle. It is a 1h30 look with a 300 climb (through the vinyards) and flat return along the Lac Leman. Here are 3 consecutive rides: 1) 1h34, IF 1.04 TSS 170 awg 192W norm 229W 2) 1h25...

    Which indoor power training option?

    Earlier this year I bought a PowerTap and am hooked to training with power, especially the motivational benefit of being able to look at ride data in WKO+. Now, as days grow short and weather bad, I am considering an indoor training option. Even after searching and reading many usefull...

    Zipp 303: Black 'dust' on brake pads

    I just bought a pair of Zipp 303 with powertap rear hub and DT aerolite spokes. Now, two questions: 1) After a 150km ride with 2 long descents (which means braking in the corners), there is an almost 1cm long build-up of black 'dust' on the brake pad. This has happed on 3 outings now, so it is...

    20/24/28 holes in zipp 303 and related questions

    My LBS (in switzerland) offered a decent deal on a 28h PowerTapSL24 hub with Zipp 303 tubular rim. Front he suggests DT240s hub also with zipp 303 tubular rim. I weigh 64kg (141lbs), and would use it for training, both flat and in the mountains. - How many spokes should I chose for resp. rear...

    lightweight children bike 12" ?

    I was looking at children bikes, and very disappointed. Children bikes are very heavy. E.g. the manufacturer scott (calling themselves "the carbon experts") has a 12" wheel bike, that weighs 8.5kg - that's more than my bike! Does anyone know of lighter commercial children bikes (age 3-6), of...

    American Classic 420 - opinions and alternatives

    I am getting a PowerTap SL 2.4 powermeter, and must decide on what wheel. Currently ride cervelo team with dura ace and velomax/easton circuit wheelset. The Easton Circuit wheelset weighs 1650 g (3.6 lbs). I weigh 65 kg (143 lbs)and ride both flat tempo and in the alps. I prefer a stiff...

    Polar meter with tripple cranks?

    Hello, Short version: - Does the polar power meter work with tripple crank-set (theory / practice)? - What is difference from PT pro to PT SL - other than 160g weight? Long version: I consider a power meter - currently just for fun, but maybe I will in 1-2 years consider competing again...

    Giant TCR CW opinions and spec choices

    Hello, I'm helping my mother to buy a really nice road-bike but with a flatbar. We are looking at the Giant TCR CW in size XS, and plan to equip it with a flatbar. Below are the proposed specs. I would be grateful to hear opinions on proposed setup, and alternatives both complete and for...

    Tripple crankset, useable gears ?

    I got a cervelo soloist team with dura ace 10 speed and fsa crankset. Since I often cycle alpine trips in my wife's tempo, I thought a triple crankset would be useful. Of course the small front-chainring, cannot work with the smaller rear-chainrings. But which gear-combination should work with...

    Clip-on aerobars on tapered handlebar

    Does anyone have recommendations or soutions for adding clip-on aerobars to a handlebar, which tapers from 32mm in the center to 26mm quite far out towards the sides? I recently bought a cervelo soloist team, and am very happy with it. However, I now realise that the supplied handlebar (FSA...

    Which PM for right/left asymetry measurements

    Hi, I'm considering to buy a power-meter option. However, in addition to the power-training, my purpose would be to monitor right/left leg asymetry. My left kne got botched in a mountaineering accident (ACL reconstructed etc.), and since I have the impression that I'm not cycling symetrically...
