Hi I’m 178 cm. I sit on 73,5cm. I have no idea what my inseam is 😄 what bikes are you riding now? Or have ridden? You should look and compare at geometry geeks. Spontaneously I’d say go for 56. Mostly because I prefer an aggressive fit. But I can’t really recommend a size before i know what bike you have had before, how you ride and if you have any issues on the bike. Where do you live?

@@Nilex1994 Hi I have no experience in the Cervelo unfortunately. So can’t advice in this case. All I can say is that you won’t be disappointed if you go with the new Ostro. Both bikes are looking nice, even though the S5 is a bit more bold 😄

I haven't ridden an ostro but I have thousands of km on the s5. Some very very long rides, some races, a lot of hill climbs and social rides. I can say the S5 is connected, sharp, has great road feel and is responsive. However it is not forgiving, easy to ride slow, or suitable for high winds , or great for decending. Of course this is just my opinion. I would buy the s5 if you do a lot of interval training, races or want something to be inspired to push yourself. I'm also looking at buying a factor because I want something that is special, cervelo is just so popular it doesn't give me the feeling of riding something special. I'm also considering a look 795 fwiw.

The wheels are great. I absolutely love them. Most striking feature is stability and light weight.

Yes this is a size 54. Im 178cm. I normally ride 52/54. My One is a size 52. Bike is for sale if you are interested :)

I rode a total of almost 400km on it in Barcelona. Weather was terrible. Lots of wind and cold. But the bike was just unbelievable. I can’t say if it’s the wheels the bike or both in combination that makes the bike feel so good. I rode outside here in Sweden yesterday and did some high threshold intervals. I was flying and it felt effortless 😅 In all honesty it’s not much more you can ask of a high end bike, new Ostro has it all.

@@cyclingfactorysweden thnx! Nearly new bike day here. Looking forward to ride the Ostro Vam 2. 😃

Hi I have been riding around 5 bars. The maximum recommended tire pressure is 5 bars for 28mm tires. And 28 mm is also the minimum width that you must use. I’m around 72kg at the point of making the video. I rode 4,5 bars yesterday and it feels fine. Haven’t done proper sprinting yet and don’t know if it will feel spongy, time will tell 😄

Thanks for your feedback. The wheels also come with black decals. I sort of like this look. It’s a bit old school.

Hi I haven’t really experienced any issues with the rear axle. Not in this model or the previous one. As long as you have some play in the rear derailleur hanger it’s easy to slide the axle through with some help from your hand lifting/adjusting the rear derailleur a tiny bit. I have never experienced creaking on T47 BB. Compression plug is another story. That issue is something I have came across on several Factors and unfortunately this new model as well. Making it impossible to ride without a hand on the bars. Very annoying and can’t really figure out how to solve it.

What is the problem with the compression plug?

@@rafluyten1885 General consumers and Pro Tour Teams were having major problems with not being able to tighten down the steer tube compression plug tight enough. Therefore, people had to overtighten it way past the recommended torque value just to keep it tight. As a result, the carbon steer tubes were cracking or completely breaking because there was a manufacture defect in the way the compression plug expands inside of the steer tube and also from the overtightening. Supposedly Factor starting shipping new bikes with an updated compression plug that is supposed to have fixed this problem. However, lots of people who have the older Ostro VAM and this newly released 2024 version are saying the front end of the bike is still unusually Twitchy and Unstable which is very concerning. There are several Google articles and forum posts about all of this and there are some TH-cam videos about these problems as well.

Im 178 cm and normally sit on 73,5cm saddle to cc on crankset. I normally go with 52 or 54. In this case a bought a 54 because it was available for quick delivery and in Sweden most people ride a size 54/56.

Well I guess it’s “easy” if you go with DA or full red group set . And in all honesty the scale I used is not the most reliable one. It showed 7.1kg with pedals (7,01kg without) and I know my Ultegra pedals aren’t that light 😅 I might have to invest in a better scale for the future.

@@cyclingfactorysweden Yeah I guess you need to be sure that the scale is accurate, but I do think that 6.8kg is not as 'easy' as Factor thinks.

Hi No unfortunately I didn’t. Bike was semi assembled with group set mounted already.

@vladipp2850 Cyclespeed Tours measured the Frame weighing 915gr. and the Fork weighed 496gr. (and that was with the Fork steer tube being slightly cut). The Seat Post weighed 213gr. Total weight for just the Frame & Fork = 1,411gr. for a size 52cm.

@@cyberx7098 cyclespeed tours was white though thats the heaviest paintjob and can add north of 100 grams for frame and fork

@@cyberx7098 cycle speed tour was a white paintjob which is the heaviest and can add to the weight of the frame and fork 100 grams ,this naked black carbon frame is the lightest option

It’s super responsive and nimble. I did 5 climbs today. 4 of them was “small” and one around 20 min. With this type of bike I expect it to be good at climbing and it doesn’t disappoint. I have 120km and 1850 m of altitude tomorrow.
