    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...

    purchasing trainer for petite road bike...

    We have a blackburn ultrastand, and that fits both my 700c bike and my wife's 650c bike. Bought this because it was specified compatible with 650c. I read that some tacx require an adapter to fit 650c wheels, which is OK if you use only 650c, but cumbersome if you switch between 650c an 700c. On...

    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

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

    Given all your good recommendation, I just wanted to update a bit. - I did increase FTP as argued by Dave. - cleaning roller helped a bit on the indoor. But now days are longer, so early morning or late evening rides outdoor become preferable alternatives. - the TSB combined with intense...

    100W Hamstring booster - or just bad pedaling?

    Just to update on original thoughts. After the replies, and reading a small subset of the 42 pages pedaling thread, I paid bit more attention to the pedaling. What I first described as Hamstring pull, is perhaps just as much of the 'top-forward-push' / 'bottom-backwards-pull' nature. Yet, I...

    100W Hamstring booster - or just bad pedaling?

    Thanks for info and suggestions. Much appreciated. Wow, that 42 pages thread on pedaling style is indeed opnionated. A few pages in, I decided to go for a ride instead...

    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?

    Thanks for the tip. I dont know 'simple green'. Are we talking house cleaning product or chain degreasing product? Dave: thanks again. I'm academic in europe - far from high end hotels with gyms. So running it is... I don't do mountaineering anymore :(. It was the hard stuff that pleased me...

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

    Appreciate the very true remark. The point is that my 'challenge' is to grow CTL with a very limited amount of training time. I have already slowed down - once rode >10000 kms/year, then solo mountaineering, rock&ice climbing and what not. The ~3x1h30/week is what I have left to feel strong...

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

    Hi, thanks for a lot of good answers and recommendations. Will read manual how to check torque drift. Thanks especially for explaining the difference in pedal cycle - that makes sense in hindsight. I'll look into larger flywheel trainers. Even if it doesn't help me do 'easy spinning', it may...

    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?

    Thanks all for answers and opinions. Indeed I hadn't changed the season start/end dates (hadn't noticed them). Now the date-ranges work fine. I compeltely agree that when weight can be plotted versus time, so should ftp.

    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...

    ATL and CTL Constants Adjustment

    Concerning the time-constants, has anyone experimented with them? How were the 7 and 42 day constants established? If they were the result of analysing some statistics from multiple riders, what was the spread in values for different riders etc? In other words, how likely is it that...
