  • Will do! Sad to be parting but I'm taking a (probably permanent) break from riding DC courses and doing road bike TT events for rest of the season.

    Also #2 is arriving in September so next season is totally up in the air and selling off most of my racing stuff.

    Hounslow 100

    I do like this race.

    Here's my report:

    https://www.velouk.net/2022/06/03/report­-result-ron-brown-memorial-100m-tt/

    I wasn't aware of anyone from the forum riding - did anyone face the timekeeper?

    There was no one on fixed, which is (surprisingly) quite unusual for this event.

  • With conventional racing apparently out of favour, here is a possible alternative:

    Course de Rene Fallet

    Monsieur Fallet was a journalist who loved cycle sport, but as a spectator and reporter rather than an actual participant; he also liked a drink. He was a friend of Raymond Poulidor whom he once partnered in a Gentlemen’s GP, but had to ask Raymond to push him on any kind of climb.

    In his book ‘Poulidor Intime’ Raymond reports the sole victory in his friend’s palmares. This was in ‘Les Boucles de la Bresbe*’ which was run under Fallet’s own special system, the rules were:

    • Absolutely no breaking away.

    • Obligatory halt at every bar on the course.

    • Speed not to exceed 10 mph.

    • All competitors to be weighed before the start and after the finish. The winner is the rider who
      has gained most weight (the one who has consumed the most in the bars).

    Are there enough English pubs still in business to organise such an event in this country?

    *Bresbe - Fallet's parents' home town.

  • This sounds like the kind of thing I come up with every time I get wasted with other cyclists.

    Not sure about the 10mph limit but where do I sign?

  • Sounds like a SSMTB race. In.

  • Is it no longer possible to buy a uci approved tt bike off the peg? I’ve dabbled in a couple of tri’s, and there are local tt, team tt and duathlon series’ through autumn and winter, so looking to pick up a tt bike, but most brands seem to now only offer triathlon bikes to the masses. Is this because unless you’re racing road events at a certain level, they really couldn’t care less if the bike is uci approved or not as long as it’s safe? I know tri bikes are probably faster but I wanted to keep my racing options open.

  • Is it no longer possible to buy a uci approved tt bike off the peg?

    Was just looking at Cube Aerium earlier, there's definitely a UCI legal version. Pretty sure Cervelo P5 is legal if you remove the luggage, Look 796 Monoblade too, AFAIK. Check the UCI list, there are probably Trek, BMC, Canyon and Cannondale options.

  • To be honest it was canyon I was looking at as a value for money entry into tt (limited used options in Ireland), and none of their current offerings are uci legal.

    A guy I know can get ex team canyon and pinarello in October/November so worst case I’ll have that to fall back on, knowing they’ll be uci approved, but it would be nice to get hold of something sooner.

  • would be nice to get hold of something sooner.

    The way things are, you're probably not going to get a new bike by then anyway. Argon18 E118 Tri+ is reasonably priced and stickered, but I don't see any complete bikes in stock.

  • Is it possible to get hold of a tt or tri bike for under £4k in the uk anymore would be a good follow up question! In size XL my conclusion so far is no

  • Is it possible to get hold of a tt or tri bike for under £4k

    Depends what you mean by "get hold of". You can back order a Cervelo P/105 for £3500, but who knows when you might actually see it.

  • Managed to pick this up local to me for €800. Frameset is immaculate but it has an odd mish mash of parts (6800 mechs, da shifters and 6600 cranks, entry level mismatched wheelset), the chain is absolutely caked in grease, and the setup needs fettling, but it’s something to build on.

  • Exactly, get hold of as I’m actually get it and ride it!

  • This seems like the best place to ask...

    For some bizarre reason, some time ago, I decided to sign up to an Ironman 70.3. I didn't want to spend loads on equipment I may not use again, so managed to secure an Argon 18 E80 frameset for <£200 and am finishing it off with some bits from the parts bin and some very cheap alu aero bars.

    I've now discovered that the frame doesn't come with the brakes, which appears to be a bit of a PITA. They are Tektro R725 side/horizontal-pull things and I cannot find any for sale online. I'm also struggling to find a similar alternative. Does anybody know of a solution? High probability of me being thick and the solution is an obvious one.

  • Do they use the Shimano Direct Mount "standard" or something else?

    I have some similar brakes that came on my Shiv but the Shiv ones aren't Shimano Direct Mount. I have hydraulic rim brakes on it now so these are no good to me. You could try them?

  • High probability of me being thick and the solution is an obvious one.

    You can fit a normal caliper to the front of the fork through that centre bolt hole. May take a bit of finagling as the counterbore is on the wrong side.
    The Campagnolo BR12 brake is a rebadged Tektro R725 but easier to find, there are some on ebay for £39.99

  • Ha! I did wonder if I could just put a caliper at the front, but dismissed the idea for some reason. The BR12 is perfect and I would have had no idea they were the same. Many thanks both.

  • Just had a bike fit on the TT bike. Some adjustment to cleats, changed to TT/tri saddle, more forward, and raised it by nearly 30mm compared to the "fit" I set it up with. Curious to see how its gonna work out!

    If you struggle to understand some of the words, its because I had the fit in Hungary :)

  • Raised the saddle by 3cm? My bike fitter did a similar increase for me and I've been off the bike for over 2 months now with hamstring pain...Coincidence, possibly.

    Maybe go back to the old height and increase slowly over time to the recommended height as I should have done.

  • Fair point! The effective raise shouldnt be 30mm, as the saddle had been moved forward a lot. On my race in May I had some cramps that could be attributed to a saddle position that was too low, so a drastic raise shouldnt be too bad. I'm definitely taking it easy on the first few rides just to get used to it!

  • @gbj_tester I fitted the BR12 and everything is fine, so thanks for that.

    Now having a bit of a challenge with the rear brake under the BB/chainstay. The original solution I thought would work doesn't, and I'm lost as to what will. The manual suggests TRP 822-1, but I can't find them or (assumed successor) 922-1 anywhere. Have emailed Argon 18 for guidance but no luck yet.

    The bit that is confusing me is that the frame is 'direct mount' but actually comes fitted with posts for the brakes with holes for tension springs. I have only seen this before with cantis or v brakes. I don't appear to be able to remove these posts and I cannot find any kind of alternative caliper that would fit (I don't even really know what the description would be to search for it). Do you have any suggestions for an alternative? TIA.

  • Hey all, looking to transition from outdoor track to fixed tt for the winter and very keen to do some CTT races. Was just looking for recommendations for regularly run races/good courses within train-able + short ride on fixed tt distance from SE London. Also would appreciate any beginner tips that are easy to miss when starting out with fixed tt. Cheers!

  • fixed tt for the winter

    There are no TTs in the winter. Well, there's Christmas and new year, but the main season runs Feb to Oct, and more like Apr to Aug for evening events.

    This is your starting point for SE London https://www.cyclingtimetrials.org.uk/clu­b-events?district_id=16 but bear in mind there's nothing very near town as courses need low traffic and no traffic lights. Q10/27 starting and finishing at Farningham is probably the closest.

    Fixed specific tips: Read Regulation 14 carefully, gear to average about 5rpm below what you thing your neutral condition steady state race speed requires, e.g. if you're averaging 20mph and you like to be doing 90rpm to hit your FTP, then you probably want about 78" on your TT bike.

  • Had a distinctly too cold TT on Sunday, couldn't get the legs going at all for a short 53.
    Both power and HR was well down on normal.
    Fastest time on the day was a 48:18, so it wasn't a treacle day all-round, but the early starters (myself included) all seemed to struggle from the post race chat.
    I suspect the rank 'flu I had last week didn't help
