    12/13 speed systems aero

    :rolleyes: emmm let's burn the bridge. No way back but forward. Looks rather clean don't you think? So now for that cheapo derailleur It certainly looks the part but the pulleys are well naff and there is too much play on the hanger for my liking. After aligning ... the alignment pulley...

    12/13 speed systems aero

    So the crank update: I didn't go to the LBS , instead I went to the local hardware store and bought a set of torq keys for €1.30. So you can see the instant weight loss... bye bye spider and 2 chainrings. Hello new aero crank See that I used threadlock when putting the mount bolts...

    12/13 speed systems aero

    Point taken and very valid. The YRET cassette is manufactured in blocks with some single gears for the smaller sprockets. I will ask the seller if I can buy some spacers so I can play with the setup.

    12/13 speed systems aero

    Holy Molly... I need to weigh it but I have a bag of shimano 105 shifters, dérailleurs and chain that weigh a considerable amount. The 12 speed cassette fits with a little spare space. The rival cranks are off and cleaned. Torque screws examined and it will be down to the LBS tomorrow to get the...

    12/13 speed systems aero

    I reckon this is lighter than a 11 speed shimano di2 and more aero for a lot less and easier to install ... anyways let's see how I get on

    12/13 speed systems aero

    Oh I do like it. Every day is special. I say everyday is my birthday but I have given up cake for something better. Drool Now I just need some rain so that I can start the 12/13 speed rebuild. The crunch will be if the cassette fits on the hub so that will be the first thing for me to try.

    Vosadrian's V20 Journey - Australia

    Don't want to hijack the thread but I thought higher spoke count added to stiffer wheel. If the rear is going to end up covered disc... does a lighter spoke count really matter? The bike weighs quite a bit so it's not as though you need to save ounces? Its just one of my other projects is...

    12/13 speed systems aero

    Tempting... just for the experience and as its in Amsterdam... no friggin massive hills. I am sure they are quite clever and invent some sort of venturi wind tunnel you will have to cycle through. I will have to investigate

    12/13 speed systems aero

    Well Well Well What's brewing in the pot? I bought and received 2 sram flat topped 12 speed chains. I can tell you now ... that chain is a win win chicken dinner. Its so slippery its like an eel and even more so its aero. Stone have produced an aero 12 speed chainring that fits in place of...

    Homebuild - Super V15

    With the number of cars parked outside, it looks like really early morning. When ever I christen a build ... I do the same. You will feel better when you get clipped in. Just use one foot first and use the other foot as a balance. Something tells me you are already an experienced rider. Great...

    My Very First Recumbent is a V20

    The 28mm is really comfortable... is your rim wide enough though for it to still be aero? Depends what you want to do with bike... KOMS or training.

    Why have 12speed when you can have 13?

    OK... I noticed a trend coming out of China that they are producing one piece , high quality cmc machined 12 speed cassettes that are shimano hyper glide compatible ... so it's not too difficult to imagine a 13th 42t sprocket sitting at the end of it. Why have 12 speed when you can have 13...

    Vendetta off the trainer

    When ever you get one remember ... take chain off smaller chainring, derailleur facing you, glove under right knee... and it should be easy. Changing tubeless tires was the easiest with :- just install it for a few days with an inner tube and then do the inner tube removal and sealant replace...
