    Punctures on trainer

    I'm getting punctures on my trainer (Tacx Vortex). Normal bike, normal wheels, calibrated correctly, and running the Continental trainer tyre. This started a few months back, I'm getting one a week or so, even with new tubes. Just not sure where it's coming from - they seem to be either a...

    Double Century, final prep?

    Have a hilly double century in 3 weeks. Going well on a diet of hilly metric 100's, two or three a week with a harder shorter day thrown in for 10 hours or so, 250 km's a week. But ... wondering if I should throw in a (much) longer ride, say 160 km/100 mile? Catch is, where i live, that...

    Campy shifting problems

    Hi all Got a bit of a problem with my Campy Chorus rear derailleur. Basically, what I would describe it as is as if the cable isn't pulling back (down) the cassette enough. On either end of the cassette it's fine, but across the middle, if I shift up (toward the biggest cog), it tends to...

    6 week adaption?

    I read regularly that there's a 6 week adaption period for any training. Can someone just expand on this a little? For example, if I'm doing regular training, then suddenly have a big week with lots of extra work, will I suddenly see a "kick" in 6 weeks - but not much benefit inside that...

    SST on rolling hills?

    Hi Just moved house, and my flat 50 km loop is a thing of the past. I now have lots of rolling hills ... not all that long, or even steep, but hills nontheless. Which means, less flat, more up and more importantly, more down. I would appreciated advice/suggestions on how best to get in my SST...

    1 x 20 a waste of time?

    This is the time of the year when I was trying to do some serious FT/SST work, building through the winter. Mainly 2 x 20's a couple of times a week, mixed with some Level 3 rides outside. Just trying to crank things up prior to my targeted events next year (mainly centuries etc.) But .. v...

    2 bikes, same position but ??

    I have two (very fine) road bikes from different manufacturers, each set up exactly the same position-wise. Well, as near as exact as I can get. But one feels more "easy" in terms of fit than the other. I'm not talking about ride quality or anything else, just the relationship of body to bike...

    HAC 4 vs HAC 5?

    I've been using a HAC 4 for a while now, have a love/hate relationship with it. Love the features, hate the unreliability. Now mine has stopped working altogether, so I'm looking at buying either another HAC 4 or a HAC 5. Wondering then if anyone has moved on/up from the HAC 4 to a HAC 5, and...

    What training between close events?

    I do a series of event type rides ... centuries and such, though I'm in Europe, so it's Etape de Tour, Tour of Flanders etc. etc. This year, i have a series of these planned, and they often seem to fall about 3 weeks apart. I've read that there's not much benefit to training from about 14 days...

    Spare time. Big miles or not?

    I'm no racer, but do about 10 000 km's a year with a few highlighted rides through the season. I've been working on "building" for a series of event rides through April May. These are 130 - 150 km rides, with a reasonable amount of hard hills and shorter climbs. So far, have been doing L4 2 x...

    Huge Tyre shootout/test in "Le Cycle"

    Don't know if there's anyone here who reads/gets the French "Le Cycle", but for the tyre concious rider, the latest edition (360, Feb 2007) has a shootout of 100 tyres and tubulars. Basic comparisons are weight, cost, adherance (tested by putting the tyre on a damp bitumenized board which is...

    Removable mudguards - Zefal or SKS?

    Anyone have any experience of the SKS Raceblades or Zefal Protektor? Both clip on "semi-full" mudguards for road bikes, but wondering if there's any advantage of one over the other? Thanks

    Cracked frame. Why?

    Hi I have (had!) a Gios Cinquantenario alu frame. Nice bike. Bought it off a guy who raced (not much .. 4500 kms) for one season. Did one season myself - not racing - another 8500 kms. One day, on a straight road and at a moderate speed with no obstacles = i.e. for no apparent reason - front...

    Training Log problem - Excel gurus?

    I have an Excel training Log that I found on the net and have adapted for my own use. Works fine for what i need. But ... time needs to be entered in minutes for the average speed calculation to work. I would rather enter time in hh:min:sec format (01:43:56 for ex), but then can't work out how...

    Legs or cardio weakness. How to tell?

    Newish to riding, OK on the flats, but not getting up hills all that well. Not overweight (probably the reverse actually, I'm pretty skinny), but am getting dropped on any decent rise .. though seem to pull some of that back on really long climbs. How can I tell if the limiting factor for me is...

    10 speed chain w 8 speed cranks?

    Just picked up a new/second hand bike. All fine - but discovered that I have 8 speed cranks with what is otherwise a 10 speed (chorus/record) system. I have a very good LBS who tells me that it can be fine (though not entirely kosher). However, I'm having trouble going from large to small, as...

    Small frames = steep angles. Why?

    My wife just got herself a nice old Colnago bike/frame. Catch is, at 49 cm c-c, the seat tube is so steep (75 degrees from what I can see), that to get anything approaching the right setback, the seat is pushed back to the end of its rails. Why not a more "normal" seat angle ... 73 degrees or...
