• The Giro Purist thread1 year 9 weeks agoThe other thing with Sanchez

    The other thing with Sanchez is that IF he gets his much desired stage win it's quite likely he'll crest a few KOM's on the way and he could easily have a blockbuster 'Voeckler' type stage.

    Either way he'll either be in contention on GC picking up regular points or if he falls behind he could easily pull off a 'spetacollo'.....for cheaper than Nizzolo or Kiserlovski(did-dig arsene Wink )

    Here is my newly acquired Tarmac Comp 2012. I was very lucky with the price, £1400 inc a £100 trade in at Evans cycles. Very happy indeed with the bike. I' ve changed the tyres to some Continental tyres off my old bike, still trying to decide about changing the seat, as I have a Stella slr off my old bike?

    Thank you.

    I 100% don't see Cav winning the points jersey. For Cav to win the jersey he needs to win every point he can on flat stages and at intermediate sprints and he needs for the climbers to all be taking points from each other in the hills, I don't see both happening.

    Also, even 5 stage wins wouldn't probably score as many fantasy points as Nibali who's priced about the same.

    I considered both Weening and Sanchez, Weening in particular as his team has no real mountain leader so he should be free to do as he pleases, but both I'm not sure if he can sustain his form from a month or so ago, he was already starting to fall off in the Ardennes. Sanchez though was a tough one, he's been in poor form and his stated ambitions are very low (just wants a stage win) so I'm not sure he sees himself as an actual contender but he's cheap for a guy who could realistically podium.

  • Giro - Stage 11 year 9 weeks agoI'm probably going to do both

    I'm probably going to do both teams as purist, due to the fact that Exeter Uni decides to put our exams during the first two weeks of the Giro so I wont have time to do it properly.

    Have you cut the tag out of your shorts yet? Or peeled all stickers off your frame/rims? Seriously I saw a video of some climbing competition in Yorkshire/Lancashire here last year and they went to crazy lengths to reduce weight including machining holes into their saddles. There is a lot you can do yourself with little cost like reducing you bar tape length either end and removing the bar end plugs, etc. You might end up with an ugly beast though.

    Looks like a lot of us have similar ideas as far as tactics go picking teams for stages 1 and 2 combined so as to have 4 transfers for stage 3.

    I thought the plan of having riders 6,7,8 and 9 as cheap guys from good TTT teams was going to be a bright idea but it seems everyone's at it......although I can't help thinking there's another minor tactic being missed which 6 of mine pander to(most who know me will know what that is)?

    From this bird's eye view it is clear that vehicles are to give way to cyclists when entering or leaving the roundabout.......that means they don't have to stop.
    As for cyclists using the "road" inner roundabout, they, too, will have to give way to cyclists on the outer route when joining or leaving the system.........Understanding and self dicipline is needed all round.
    On balance, the general principle loooks good in that fast moving traffic will be moderated to negotiate the junction and when integrating with other road users.......isn't this what is required, not the dominance of one party over another?

  • Have you wasted money on super light new wheels?1 year 9 weeks agoThis reminds me of the

    This reminds me of the article about the doc who commuted on his old steel tourer with mudguards and a lightweight carbon bike. He found little difference between them.

    http://road.cc/content/news/28400-doctor-claims-carbon-offers-no-benefit...

    Also discussed in the CTC's magazine last year (PDF)

  • Have you wasted money on super light new wheels?1 year 9 weeks agoAs for the aero wheel

    As for the aero wheel analysis, it's going to need some time to give objective data in a discussion suitable form as I need to quantify the climbing to support the hypotheses.
    Broadly though Aeolus 5.0 D3s weigh the same as the Elites, and on my best bike I am 2-3 mph faster on the flat, across and with the wind and 5mph faster into the wind at 160 bpm. Data based on the first test ride I did. As for climbing, I set a Strava KOM first time up the road from Cayton Bay using the Bontys, which is a climb I normally struggle to hold any speed on as it has a kick up partway through.

    At this point however, gIven it's sunny out, I'm going to go get some more data points...

  • Better, lighter contact points1 year 9 weeks agoI'd say you'll probably feel

    I'd say you'll probably feel the most benefit by upgrading your chainset - going up to SRAM red or dura ace (not current gen, maybe 7800 or 7900 to save cash - look for second hand bargains) will not only save you weight, but will be so much stiffer than your current setup. You'll get your power down on the road far better, and gain efficiency far more than losing a few grams around your headset.

    As for your saddle woes, if you're getting a sore perineum, maybe you need to look at a saddle with a cut-out down the middle? I really like my Specialized Toupe.

  • Have you wasted money on super light new wheels?1 year 9 weeks agoOk. If you want to accept a

    Ok. If you want to accept a model, which is purely academically defined then fine. I personally wouldn't accept this model as anything more than interesting and for discussion only, completely divorced from reality.

    Anyway, some data since you ask. Were I to do this as a scientific experiment, with an intention to publish results, I'd get one of those fully wired up Factor bikes and hire a wind tunnel, using a dummy and a motor to regulate effort and provide weight and aero consistency. Sadly I only have my legs for a motor and me for a dummy...

    Hypothesis: ignoring gross aerodynamic features such as deep section rims, lighter wheels are more than 0.5% faster per kg rotational weight lost.

    Take Shimano RS20 as a baseline. List weight 1817g which we'll accept since we're looking at gross weight changes, not trying to derive a graph of weight vs speed.
    Same bike, same tyres, same drivetrain, same weather, same day within a 3 hour period, same route, same traffic conditions (i.e. not affecting speed, so quiet roads with occasional traffic passing at a reasonable speed, but no slipstream from continual traffic). The route in question is round Forge Valley in Yorkshire, and is on Strava as Forge Valley Up. Not very long, but easy to ride with consistent effort. Effort measured by heart rate, since I don't own a power meter, effort being targeted at 150 bpm which I can hold reasonably closely. Rider weight and position on bike is near enough constant. In this case only measuring 1 lap, which does not give enough data points for a statistical analysis. This was done because I had both the Elites and the RS20s out of action due to potholes and fell back to the handbuilts. So when all were up and running again, I did a test because I'd done a long ride on the handbuilts and was subjectively horrified at how slow I'd been.

    Handbuilt wheel ~ 2100g (measured, no tape, tube, tyre, skewer, cassette, however scales accurate to maybe +/- 50g) 5.5% slower +/- 0.5%

    Mavic Ksyrium Elite 1550g list weight 8% faster +/- 0.5%.

    So for the one ride I did to explicitly measure this about a year ago, there is a difference. Whether it is significant is arguable for a single data point, but scientifically you'd note is as interesting and move along.

    Riding those wheels over a long period gives more data points, but rider weight, drive train, weather, tyre pressure, effort level, mood (i.e. subjective elements), bike upgrades, traffic and so on influence the data. I've not normalised the results for average heart rate, excluding rides which are influenced by 'extreme' weather such as high winds or rain, and I'm assuming that the amount of climbing or severity of it averages out over time because I tend to ride the same roads, with few variances. Looking at those rides you see a similar correlation.

    The handbuilt wheels, ridden from 2003 to 2008, but with data points from 2007 onwards (when I bought a GPS, and so could automatically record to computer for analysis)
    412 rides, 6.386% slower with a 19.0% 1st standard deviation on the average

    RS20 452 rides 2008 to 2012 0% (benchmark), 1st standard deviation 16.3%

    Ksyrium Elite, 2011-2013, 48 rides 3.367% faster 1st standard deviation 10.0%

    During the whole time there are periods off the bike due to injury or illness, wildly varying rider weights, since my weight swings wildly (I've been 3 stone heavier and 1 stone lighter than I am now), and there are rides where I'm doing recovery through to hard pushing ones, plus adverse weather and differing loads and positions on the bike.

    Since I've moved down south I've been riding the RS20s with panniers on different roads, so those are excluded from the analysis.

    A t test on the handbuilt vs the rs20 however gives the results as NOT being significantly different due to the large standard deviation. If I wanted to be rigorous and try to get a better analysis, I'd now go through normalising the data, testing for outliers, ignoring anything with incomplete data (i.e. ridden without heart rate) and so on, chop the data sets into a fraction of their current size doing so, and feed it all into an ANOVA, but that's more work than I'm interested in doing on a bank holiday weekend. So I'm happy to forego that.

    Despite the t test, I am not seeing any data which contradicts my original hypothesis that lighter wheels are faster, though I am happy to accept the analysis is not complete.
