  • You can definitely go fast on an older frame with a good position, suit helmet and wheels. The bigger drawback than aero penalty is most modern wheels won't fit into an older frame and older wheels don't handle like modern wheels. It took me longer than it should have done to realise that a 30mm wide rim won't fit into 28 mm chainstays

  • Yeh true I had thought about that a bit.
    Presumably old wheels are fine though, that’s what I used to race on with 23-25mm and I did ok! For a 20-40km race I’m not so worried about bigger tyres. I would if I was going for an Ironman or something stupid but I’m not!

    Might give it a go. Lot less ££ to risk than buying a newer frame or bike

  • Yes, would love to! Im abroad until end of Jan, but i’ll drop you a message when im back.

    Also thanks for the recommendations @SCS and @onyerbike .

    Now, if im looking to upgrade my helmet from the Giro air attack, and I am looking for something with good resale value, what do we think of the POC tempor for £180 brand new?

    I could only find them over £200 used. I /think/ it would work with my position, but I’d have the chance to try it on and eyeball it -which isnt perfect, but its something. And again, I think it would have good resale value if it doesnt work out. Has anyone on here used one before?

  • Anecdotally I understand that it works really well tor some people depending on their shoulder width and how low they can get their head....and in low yaw conditions. If you are riding out and back TT's or track then definitely worth considering but it's likely something else will be faster across more angles/conditions/head positions.

    Agree on resale value as it's been used by Bigham so people will buy it just because he's had success with it (but now rides something else)

  • and in low yaw conditions. If you are riding out and back TT's or track

    Yeah...This is the course of my main race for '23, I don't think this is gonna be a winner then :)

  • Hah maybe not....I guess if it's low wind and you can hold your head very still it could be ok....

    Where I got my bike fit done, the fitter had a load of TT helmets and he took lots of photos of each helmet in position (tucked, tired tuck etc). Visually he discounted some straight away which narrowed it down to 3 options based on the events I was targeting.

    When the weather is better I am going to Chung method test all three and then buy the one that's quickest, although hoping my Aerohead still comes out on top!

  • Road bike categories in CTT TTs: is there a list of regs?

    Mainly want to know maximum rim depth.

  • is there a list of regs?

    There's no universal national regulation. National events are 65mm, but others vary, from 90mm for @xavierdisley events to as little as 30mm with some organisers.

  • I suspected it was an organiser specific thing, but as there’s a road bike TT national champs this year there must be a reg. If Tester doesn’t know it, no one does.

  • road bike TT national champs this year there must be a reg

    There is (although god help anybody trying to find it on the CTT site*), it will be 65mm same as Sigma Sport Classic series

    *ETA: 2022 Start Sheet lists the regs., we'll have to assume for now that there will be no change for 2023.

  • Ah thanks 👍🏻

  • Yes, should be 65 at the National... basically the Zipp 404 or shallower.

  • Now, does anyone have a set of <60mm rim brake carbon wheels they'd lend me for three weekends at the end of Feb and 1st of October...?

  • I was going to sell my old Powertap 404s but then decided it's not worth it and to keep them until I kill them. Unfortunately this means they're being rebuilt with new spokes and I don't have them. There must be tonnes of aero rim brake wheels around in sheds from everyone upgrading to disc bikes.

  • I know right? Thing is, Wiggle have their super light, 50mm deep, crash replacement / 3 year warranty wheels winking at me for not much more than a second hand set of unknown wear on ebay.

    TBH I like my shallow aluminium wheels and don't need another set, but seems silly not to go deep for TTs.

  • Does anyone know if LFGSS CC is going to be registered with CTTC this year?

  • Don't believe the hype... there aren't 20 Watts to be had for going a few cm deeper on the rim. Those figures are extracted at the best possible yew angle, which obviously never happens in real life, let alone in a TT.
    If you have money to waste, by all means, get the best possible equipment, but if not, then invest wisely and wheels would be at the very bottom of my wish list.
    A good winter of Pilates might give you core strength and flexibility, necessary to hold a good aero position for the hour or so needed at the National Road Bike champs (should be around 25 miles, give or take). That is worth some serious Watts. I find that without the help of tribars, I can hold a good position with flat back and head tucked in for a couple of minutes only, before I need to change it... so long way to go here... maybe you can do better

  • The person to ask is @Velocio but since CTT isn't as overtly contentious as BC, I'd hope so.
    Need to start planning the season.
    Big aim remains sub 50 25.
    Small aim is beating @dbr time up Sa Calobra.

  • Does anyone know if LFGSS CC is going to be registered with CTTC this year?

    Yup, we will be :)

    Not sure I've seen a renewal email, so let me chase it up.

  • great, thank you.

    With not resubscribing to BC I'll be looking to CTTC for my racing buzz.

    I wonder if this is the boost TTs needed (I assume not)

  • Renewal done.

    I had changed my email and not received the notification email, it had expired 4 days ago and I've just renewed for another year.

  • thank you very much, really appreciated

  • CTTC

    It's just CTT, or RTTC if you're a retrogrouch who thinks modern life is rubbish, or RRC if you're LARPing as a flapper

  • guess I've got a lot to learn

  • Anyone got a set of Vukas or similar kicking about? I'm still looking for aerobars to go on the MTB for AMR but can't find what I want in the small clip-on style so figure another set of Vukas will work.
