    Replacement for Speedplay Frog

    Well that's weird that you havent got a reply... I use look pedals and cleats. If you get hardened fiberglass look cleats then they will last longer. There are three different types of float. Black cleats are 0 float, grey are 4 degrees of float and red are 9 degrees. I believe the reinforced...

    V20 crank length?

    I got them cut down at an engineering company in the UK: www.highpath.co.uk My conversation with Patrick "The Rival range is solid, but it does have rather deep fluting at the back. I can shorten to 150 from 172.5 but the resulting pedal hole is thinner than ideal. If you are happy to have them...

    100 miles in under 3 hours

    I have been watching GCN episodes of SI beating 2 roadies x pro peloton riders and then doing it again for 3... might be that new helmet (Giro Air) LOL... and that was without a rear disc wheel. Speaking of which ... that rear disc wheel that broke the record looked incredible. It had golf ball...

    V20 crank length?

    Well... I got my best results on a 165mm crank but I am running 155mm. After every ride with the 165mm cranks my knees were in pain. With the 155 my knees are fine. So for me cycling every day with 155 suited me better than 165 health wise. I am 5'10. The 155s make my legs more aero and with...

    grippy s40 (2020) tires

    Yep... sorry about your spill. I run continental grand prix 5000 tubeless and when it rains I find the road slippery as hell. My climate is dry days 98% of the time so roads have rubber oil layer so when it rains it's very slippery. Best to reduce the pressure in your tires when its wet. Make...

    "Twit Tawoo" comes to mind. Anyways... poor man's ceramic speed. Fine for me as I am a few kilos over my race weight.

    Chain Reaction

    I am pretty sure our paths haven't finished crossing. One way or another. Kudos to you. Great sport eh! I really think when people see us on our Vs' they either feel fear or get very excited.

    Chain Reaction

    Ok ... status report time. I am back out on the vendetta. Everything seemed to take so long. I upgraded the derailleur to the shimano r8000 and changed the cage to an Alibaba bargain of the century... So on the bike it seems more effortless and like zero chain clutter too. When putting the...

    What did you do to your Cruzbike today?

    If you change your chains each year then you dont need to change your cassette or chainrings. It's cheaper just to throw out the chains. Eventually though everything wears out. Campagnolo has a ti cassette that seems for everlasting which has more sprockets than the shimano dura ace cassette...

    Marco in the news ...GCN no less (italy)

    I had the pleasure of meeting Marco with Larry at the worlds in France last year. Sofia was there too... She seems so so interested in everything. I noticed that GCN Italia didn't want to try his hell and back recumbent ... last version. There is a youtube video on how he made it. Brilliant...

    V20 for sale

    Lovely wheelset. Why not sell that wheelset and buy a cheaper 650b disc brake wheelset. Then that would put you lower and you will still be going faster than ever! Just switch over to trp spyre hy/rd calipers with 160 and 140 rotors

    Curved Slider vs Longer Chain Stay

    Try going up a long hill with a long chainstay and you will fall off. Well I did twice. I am 5' 10". The hill in question went on and on 5%+ with camber on the sides... just a wobble and an over correction and yer off. I now run with the medium chainstay and the curved slider.

    Vendetta V20 for sale [frameset, standard chainstay], UK & EU

    What a shame... n+1... understand though. Bikes take space. Perhaps I end up with a miniaturized V20 that i can put in my display cabinet ... quite a nice present for someone who loves their Vendetta.

    Dialing in fit on a V20

    Set up your rear derailleur first... then adjust boom to your hearts content. I found that the choice of handlebar has significant effect. When you are in a comfortable fit and can ride without trouble then put the front derailleur on. I found it's easier to set up the front derailleur without...
