    My heart broke with my boom today

    It sounds as if it would not work. Thank you for the offer. I will certainly ask when I pick up the bike. The parts have not gotten to the bike shop yet so I don't have the bike back.

    My heart broke with my boom today

    Vicki C, If a new style chain stay fits a Silvio 2, I have a like-new (200 dry-road miles) standard length chainstay from my 2018 V20 that I would be willing to part with. It’s left over after swapping my V20 to the long chainstay. Bill

    Longer chainstay = more speed

    The maximum height of your knee relative to your shoulders is determined by the seat recline angle, the length of your torso, and the length of your femur. None of those variables are changed by raising your feet. Below is an animation of a study I did several years ago. It's purpose was to...

    Medium Chainstay needed for V 2.0

    I just want to go back to the way I had it before I tried using the longer chainstay, since the longer chainstay puts my handlebars in a position that restricts my leg movements. Certain torso and leg length combinations just will not work with the longer chainstay and mine is one of them...

    Medium Chainstay needed for V 2.0

    I am assuming that because it is Yellow, it is off of a V2.0, not a V20. Would you like to trade the all aluminum boom insert piece that has the handlebar clamps on one end and inserts into the curved bottom bracket boom? Depending on your height, some riders trim the ends of their’s in order...

    Climbing hills on a V20?

    Well it seems that re-assembly of my V20 is behind schedule, so I won't be able to pick it up until Saturday afternoon. Since the front end was still in pieces, I dropped off the new size Large chainstay. I was surprised that despite a ~ 5" difference in length, the Large chainstay was still...

    Crash

    Well, with the current design, anyway. A set screw or two for the hangar, plus a flanged mate design for the fork-chainstay interface would prevent this need.

    Crash

    A T50 has what you would recognize as a “normal “ dropout. As the boom length is adjusted, the chain stays rotate around a point that is not coincident with the axle. This causes two undesirable things to happen. (1)The length of chain needed changes because the distance from the axle to the...

    Climbing hills on a V20?

    I've instructed the shop to go ahead and install the Di2 system using the existing chainstay. They say it shouldn't be a problem switching to a longer chainstay if I decide to go that route, and this will allow me to do some coast down comparisons to see if a higher BB actually does result in...

    Climbing hills on a V20?

    I just had the guy at the shop measure the distance from the floor to the center of the BB, which turned out to be 26". With an inseam of 32", I'm not sure what the optimum height would be for me. How can I order just a chainstay?

    Climbing hills on a V20?

    ...is nowhere horizontal either but definitely more than this picture. Get the BB at the right height is a dance between crank length, chainstay length, and your inseam - which will determine how much the boom and slider will pivot back toward you in the seat. I would suggest trying a 21.5"...

    THE NEW Q IS COMING

    It appears to be a reuse of the S40s chainstay based on the height of the front derailleur hanger provided in the pic. Not an issue for a 1x11 configuration, but may limit a 2x?? or 3x?? configuration due to the height of the hanger relative to the large chainring.

    THE NEW Q IS COMING

    Will the Q45 come with three chainstay length options as the Vendetta does??? Will there be an exchange system for chain-stays, so the correct length can be found without buying a second or third chainstay?

    V20 vs. S40 Compared

    Nice write up. My understanding is there are 3 different lengths of chainstay. 19, 21.5, and 23". I switched from the short to medium on my S40 and thought it a better fit. Which length did you switch out specifically on your V20? Good to recognize the difference in seat height of the two...

    S40 questions

    S40, or any other CB on a turbo trainer. How do you get around the longer skewer issue? The skewers for my TT have a particular shaped end but are standard length, so won't manage the front of the S40 with the fork and chainstay arrangement.

    Bike Sebring 2018

    I have the Thor seat with ADEM headrest set up per the instructions Ratz wrote up, but I am not sure what angle of recline that gives. It basically follows the curve of the frame, but because the shoulder area curves up it pushes the upper body and head higher into the wind. Cruzbike posted a...

    You can get different length chainstays, longer means BB lifts higher, shorter means BB drops lower for any given leg length. For reference I have XSeam 46” with standard chainstay, the BB is about 3 inches above the lowest part of the seat on my V20. I calculated that the next size chainstay...

    Larry, this was a VERY good reply with lots of info, especially about the boom when horizontal ! Another question for you! Is there an optimum BB height above the seat base lowest position? The S40 front fork can handle a 700c * 38, so with a 80 kg rider, the recommended tyre pressure is 50...

    ...it might be cheaper to opt for a smaller "little ring". #4 Crank length. Base on you question it appears you are asking about the chainstay length - I will address both. Chainstay: There is a large chainstay that is 2" longer than the standard. I think with you height, you are probably on...

    Why is the adjustable front boom curved on the S40 and V20?

    In short it was to allow the front derailleur to adjust independently of the boom length changes. And now the the long version: The first version of the Silvio version 1.0 or the predecessor of the S40 and the vendetta had the boom straight and front derailleur attached directly to the boom...
