    Hi @dtseng , let's have a ride report please?

    I think I want a V20....

    Maybe you are too down in the seat? Adjust the boom so you have some bend in the leg when fully extended. That will keep you more upright and reduce bottom bracket swing. Go down slower slopes and just keep pedaling. If you stop pedaling you will probably freeze. Get to the desired speed and...

    Titanium china copy of cruzbike

    Yes I had seen that. I eventually want to set up a bike trainer in the philippines where some of my relatives are. Nice and light to move around and durable. Guess custom fitting might be a little difficult with titanium but I guess if you gave them your v20 stats it could almost be the ideal...

    New shoes

    Aliexpress shoes... eat your heart out Donald. At €80 a pop they are untouchable. They are ultra light too. They have screw in rubber heels so they could last for years!

    Midsole conversion with power meter pedals

    I reverted. My boom is pretty vertical and my bottom bracket too high. If I have cleat at the front of the shoe it's enough to get the bottom bracket further down giving me stability and more power. Best to try and see if it works for you.

    Paris Brest Paris: rider tracking

    This sentence has stuck with me. I am sorry you had to go thru that ordeal. I guess they thought you might be sucking their wheel? I don't think they realized the physics involved. When another rider is following it actually reduces the drag for the riders in front. Which means they don't have...

    Continental Grand Prix 5000 TL

    That was interesting. My quest to reach 50kph on the flat might just be pumping up the tires to 110 psi :D I was thinking I would have to get more aero by buying hydro disc brakes and a new aero front wheel with new DT swiss 240 swiss hub. o_O

    Paris Brest Paris: rider tracking

    Difficult.. I typically get asthma if there is wind chill and if it's been damp. I also notice it more on my vendetta than on the DF. Maybe it's because I breath thru my mouth more when putting the power on. I have actually tried some nostril openers... I saw Chris Froome use in some of his...

    Continental Grand Prix 5000 TL

    I think they are worth the money... I did. Notice recently that schwalbe are reinventing the pro1. Competition has to be good as it drives the prices down. I survived after trampolining in a crater of a pothole without a pinch flat so I know they are good.

    Paris Brest Paris: rider tracking

    Well done @Tor Hovland ... you finished. Just wondered if you have any of that video magic to go with the experience? :D:emoji_bicyclist::emoji_checkered_flag:

    Paris Brest Paris: rider tracking

    Hey @Tor Hovland ... you're doing great. I noticed your pace has dropped a little. Just to let you know my thoughts are with you. Not sure what the conditions are but maybe too much heat? It's a very long ride that I am sure you will remember. God bless

    It has became normal

    Both feet out of the pedals and sit up and try and slow down before the hop.

    World Championships 2019 - 19-21 July - Nandax - France

    Here are some incredible pictures. Fighting for first place up a nightmare hill in a velomobile! Pretty sure its Stijne Van de Maele. Different league - superfit Larry paced himself brilliantly And finished in style in the epic 3hour. (It was terribly hot when they finished)

    World Championships 2019 - 19-21 July - Nandax - France

    I didnt enter the race... one thing or another. Just blocked... found out later that my cleats had perished so probably good I didnt enter. It was quite an eye opener for me. I had my bike boom and bottom bracket too aero. It helps if your bottom bracket is level with your shoulder. And the boom...

    Helmet field testing? CdA impact

    Well I haven't done it yet but my intention is to get a full uvex face visor and try and fit it over the giro air attack. The big issue with that is the visor will mist up but I think it's worth a go. Many of us cycle with our heads at an angle.

    Helmet field testing? CdA impact

    Yes... sure looks aero but how heavy and how hot is it to wear?

    Love to get a Vendetta but?

    The Vendetta has a long wheel base. The other day I went in a huge pothole but I was at escape velocity. I was going quite fast. If I was on a DF I would have fallen off for sure. For speed I feel safer on the Vendetta.
