Cannondale FSi builds

No problem. I'm running a Smud carbon saddle with oval rails on my bike.

Hi!

Is there anyone switching from FSi Small 2015 to Small 2016 - meaning from 29 to 27.5 wheels? I'm just about to buy one of the last 2015 bikes because the 2016 small frame feels too small (but I could test it only inside the shop for a few rounds). I'm 167cm (legs 78cm) - wondering if the medium frame 2016 will work also. Any recommendations?

Cheers!
Philipp

You can use quite short stems on the F-Si (50 mm, maybe even shorter if you can find them). Keeping this in mind, you might get away with a medium.

Actually I don't have a length problem as my upperbody (and relatively long arms as well) perfectly fits the medium frame - but my legs are fitting the small frame . So in respect of standover and crank length - fitting programms recon size small with a long negative stem. And thats more or less the same with any brand
So I tried the S (2015 and 2016) and the M (2015 and 2016) and although the S (2015) proportions are looking strange it seems to fit best. But I'm used to a small 29er and so I'm not quite sure if my feeling is not biased. And when I saw that there are some people in this thread with small frames I thought maybe there is one of them switching this year - joining my thoughts

Fit should be dictated by reach/ stack not seat tube length or standover. Small frame and long negative stem might work on a road bike but this is the inverse of what you'd want handling-wise for a MTB (especially an F-Si). If you "fit" a medium then I would always tend towards the frame with the longer reach and go for the medium. WRT crank length, you could ask the shop to do a deal on the correct cranks length and stick the longer ones on ebay or just suck it up as a necessary additional cost to get the "best" bike for you...

[phlipnow]

Do you know a good stack and reach online calculator? Only found competitivecyclist - (again going for the small frame with 9-10cm stem)

This one is the best I have found:

Scroll to the right and use the second set of columns to play around with stem lengths and heights on different frames where stack/ reach are known

The F-Si frame is listed as having a PF30a bottom bracket shell. Can someone measure the width of it please? It should be either 73mm or 78mm. I'm trying to determine if it is the same as road PF30a or if there's actually a 'PF30a road' and PF30a mtb' version.

If it's the same as last year, I'm pretty sure I measured mine at 83mm wide. This pretty much eliminates the possibility of using cranks from other brands.

[ChrizZZz]

Yep, thats correct!
The same @CAAD12 and Supersix New EVO but only 73mm

BUT THE F-Si Alloy Version got still BB30!!!

[grover]

So for road bb30a they've taken a 68mm bb30 shell and added 5mm to the non drive side to make 73mm.

Mtb bb30 is 73mm wide (but symmetrical unlike road bb30a). So how have they gotten 83mm for Mtb bb30a? By adding 10mm to non drive, 5mm to each side, or something else?

[ChrizZZz]

Seems to be a normal BB30 BB

Hey guys, so here it is up for the taking. I've mentioned it before but I've switched to the dark side and racing the big red S now. I need to sell the FSi for what I have in to it. Here's a link: http://weightweenies.starbike.com/forum/viewtopic.php?f=5&t=137719

It's coming with some extras as well. Hope she finds a new home.
