Anyone out there with the new Slice RS??? How does it fit compared to other tri or road bikes, does a 52cm road bike translate to a 52cm Slice??? Looks really low in the front end any issues with getting enough height to be comfortable in the aerobars? According to the geometry of the bike it looks like I could go with a 50 or 52cm frame,any input would be greatly appreciated.
asking how a road frame size will translate to a tri frame is a pointless way of choosing sizes. I’d recommend you go get fitted.
seeing as you are new here and seem to not have an understanding of the bike you are asking about and possibly whatever set up you currently ride, at a minimum, you need to see the bike in person and test ride it, not ask random questions on the internet, cuz we are not all french models 
.
Thanks jeffp for your very insightful help 
I do have a very firm understanding of the Slice RS just asking if someone out there with any real knowledge and is willing to help, don’t need smart a@@ replies, thanks. If I had the luxury of going to a shop where they had this bike in stock in the sizes I’m considering I wouldn’t be asking for input on this forum. I have been comparing the geometry of this bike to my 51cm Cervelo P3 and looks like I could go with a 50-52cm Slice RS. Any intelligent input??? (I guess that excludes you jeffp )
The Slice RS is based on the sale geometry ad the old Slice, so geometry are in reality the same. However due to the stem on the RS, the base bar is in a specific position relative to frame size.
I would recommend utilizing the stack and reach database on ST (look in the header on the top of the site you are looking at right now), I think both the Slice, Slice RS and Cervelo is in there.
you are an idiot, if you think asking the question you asked is going to get you any information of value. you offered no insight as to your fit requirements, just a dumbass 50 or 52 going to work? work for what? someone they fit? sure. you? how in the hell are we supposed to guess that?
i failed my great and powerful OZ class, so i cannot be all knowing.
if you want to post some useful info for folks to give some less uninformed opinions on, that would be a start.
oh, and welcome to the forum!
ps pink font means something to some
Thanks again jeffp for sharing your great wisdom with all of us I was just looking for some general input and wanting to hear from others who maybe had some experience in fitting this bike, isn’t that what this forum is for exchanging info??? I already know by directly comparing the geometry of my P3 to the Slice that either the 50 or 52cm frame can be setup to fit me. Thanks for the pink letters jeffp haha
who knew it (?), but there is a MAGAZINE attached to this forum.
sniff sniff
that’s just a cold

I ride a Cannondale 54mm road bike and have the Slice RS 52mm. I got fit on it (Guru) and I actually have plenty of room to add more stem extensions (I don’t have any installed with my current fit). I sit farther back right now for a TT position, but can easily go steeper for tri geometry. I’m 5’8" with a 31" inseam if that helps.
I had similar questions about going between a 52 or 54, but the shop I ordered from recommended a 52 based on my dimensions and my current bike setup. Having a shop that can look at your current measurements, and recommend what you need really helps.
BTW, I could recommend using a fit machine (eg, Serotta, Guru), then getting your measurements and having the Slice RS adjusted. Making adjustments on this bike isn’t as simple as swapping stems, moving the aerobars back a notch, etc.
Good luck!

Thanks for jumping in Dave. I read the article and also another written by you suggesting when between frame sizes on a super bike to go with the larger size. Based on the Slice RS geometry I can fit a 50 or 52cm frame. The one thing I don’t like is the standover on the 52cm frame at 77.5cm, I’m short and the top tube would be right at my inseam. The other factor is going with the 50cm means a higher seat post height so the front end may be too low??? What are your thoughts? I’m 5’6" and currently riding a Cervelo P3.

My apoligies, meant Dan typed Dave.
“Thanks for jumping in Dave.”
dave’s not here.
those of you who are my age - but not too much older - will understand why one waits decades for the chance to write that.
no way of telling what you should write unless i know exactly what your fit coordinates are. but, at least i can tell you this: the rs is a very very good superbike for those up to 5’10" or 5’11". but the determining factors are: what aerobars are you going to ride? and what are your fit coordinates? if the standover of the 52cm bothers you, then ride the 50cm with pedestaled aerobars or high profile armrests. also, you may require the 50cm if you ride with high profile aerobars, or if you ride with a fair amount of armrest elevation drop.
Thanks for your input Dan. I do ride with a fairly low in my aerobars and will go with the stock Vision bars on the bike. Also tons of adjustment with spacers and the stem. Tough deicision when you’re between sizes.
Of course, those of us who work with several Daves and are of a certain age try to use it every chance we (OK, I) get…getting a reaction, that’s the hard part. Young’uns…sheesh.
Contribution to thread: if I’m not mistaken, Cannondale suggests letting size parity be your guide: 56 Cannondale road should try a 56 Cannondale tri, etc. Someone with access to a sourcebook sent me that info. Maybe that works for their geo…sure doesn’t for us.
if you need spacers, the stock vision bar is not the way to go. you need a bar that pedestals between the base bar and the pads/extensions combo. if you’re going to spend all that money on a bike that nice, make sure the bars on the bike are correct. in my opinion, vision is probably not the wisest spec choice for that bike. profile would have been wiser, at least for that particular bike. standard slice? yeah, you could make a case for vision. hard to make that case for the rs.
Yeah there’s alot of conflicting info on sizing out there. Based on the geometry specs for the Slice RS compared to my P3 I’m going to go with the 50cm frame. Thanks to all for your input, even you jeffp

Hi guys for whats it worth. I ride a 56cm cannondale CAAD10 / EVO but with a zero setback seatpost. I used to ride a 56cm himod slice I now ride
a 54cm slice rs black inc. I have no spacers on the stem so 70mm and 20mm of spacers under the extensions my seat hight is 785mm from bb to seat top. Very comfy on both bikes. Well I hope ill be IM MELBOURNE in under a month . Woo hoo
