Cervelo s1 2010 build

billysan

Very nice I must say, I really like this years colour S1. I prefer the details like the graphics inside the forks compared to the 09 one.

I have just built myself a very similar bike, however opted for 6700 instead of Force. Looking forward to getting out on it properly.

Hi all,

just bought cervelo s1 just to be flying on it, i was thinking of getting sram red 52/36 cranckset but it is expensive, and the rest of the group should be rival and not higher spc, rival will do it for me.


here are some questions hope you help me:
1. what bottom bracket i should buy to fit my frame and sram red cranck.
2. i was thinking to get 11-32 cassett just incase sometime i face big hill.
3. are the combination works together (rival and red).
4. do i gain any more speed than specialized sirrus as i hit 48/11 on my sirrus on descent and some flats, i bought this bike to increase my speed all the time.

i am not cycle trainer but i love to cycle, just needed this bike to get me to work faster, and i will use it only for work and keep it in garage.

thanks for any advice.

Hate to disappoint you... but i'd be amazed if you gained anything more than a token 1mph from this purchase. Unless you were riding a 30KG Dutch town bike before???

That's not to say you won't notice a difference. I myself can tell the difference between my two bikes, one of which has far greater pedigree than the other. Thing is, it's largely a matter of 'sensations' as opposed to real world, measurable differences.

Maybe 5 seconds on a long uphill at best, but the best bike is a good 3Kg's lighter and the S1 can't really be called a light-weight frame notwithstanding your component choice (wheels being the most important element).

well thanks for your honesty, but i just changed the tyre of my bike from 28mm to 25 and only lowered 2 cm the handlebar,believe it or not i gained i gained 25% without feeling tired, ofcourse that was not on the flat but rather on the way back home which is quiet gradual hilly, before that adjustment it usually take me around 35 to 40 minutes after adjustment i felt i was going faster and took me only 30 minutes so that is gain of %12.5-25

i was thinking with this bike i am going to get thiner tyre 23m , better wheel, better gear shifting, so if i save 5 minutes more i will be happy.

if i save 5 minute in my journy it means very comfortable ride and no tiredness at all, i can see the difference betwen 40 minutes and 30 minutes durtion.

for me i do not care that much about bike's weight, but some parts are important to me:
1. frame weight
2. tyre and tube size and weight.
3. crank size and weight
the rest is fine.

but thanks for your believes, if i be sure i do not gain any more speed specially on the way back home where is quiet hilly, then i will sell my new frame, as i did not bought any part yet, or i hold to it and build it in future, anyway the frame always is a good asset.

^^^ I've been reading the above post carefully - there must be some sense in there somewhere but I've failed to spot it!

Got the 2009 Cervelo S1 myself (frameset in ex. con. secondhand for £400). They certainly do 'feel' quick when you are riding them, although I'm not claiming anything like 25% improvement :shock:

warrior4life

The frame weighs around 1400g I think, Its on google somewhere, I sold the S1 last year, It was a good bike but Im pretty sure I could have had a better bike for the same money.
I dont think it was any faster than any other bike in the same price range, I agree with EKIMIKE that even super bikes give more of a sensation of speed rather than real world speed, Deep carbon rims seem to make the biggest difference to me but even thats only when the speed ramps up.

23-25 tyre, I dont think that makes a huge difference if at all, A lighter set of wheels helps, Crank size (at the moment im hearing nobody needs anything longer than 170mm and shorter cranks are the way forward). I'd say crank stiffness is more important than weight.
It takes a standard english thread BB, sram gxp works fine, I would think a 32 cassette would be a bit extreme unless you have real fitness issues?
A compact with 25 to 27 at the rear should be enough for someone with an okay fitness level unless you spin a super high cadence, Nobody can really answer a gear ratio question, Its a personal thing, If you do put 32 on the back I doubt there'll be another s1 on the planet like it.

thanks warrior4life,

i think i will sell the frame or returned to the shop if they accept it, already sold my sirrus, cos was size 58 and i am 175cm.

i will get a cheaper bike for around £500 with full equipied, and that is it, will updat the test about my new bike and the speed test, but dafenately, will not build ceverlo in that case then.

thanks alot

Im not saying sell it, Its a great frame and bombproof, For a fast commute there's probably not much better, Just for my riding I probably could have got a better frame.
The bike has many owners who love it.
You have to love your bike, If you love the bike then build it, Im sure it'll be a huge improvement over your Sirrus.
Cervelo's are like ferraris, They're a bit different and special, A thoroughbred bike.
I'm sure you'll love it.

zindu

well thanks, but i can buy whole bike for around £500, that is way cheaper than cervelo, i just bought it, because some people on some forum said they increased to 23 mph with cervelo, while on others they did not reached that speed, i can reach 20 mph on semmi flat road on sirrus, but i have mounted aero tri bar on it, trust me i changed the tyre and tube from sirrus to gatrskoni 25m and increased speed by %12.5-25 in speed on gradual hilly road, but when i was descenting it increases my speed by 12.5% while the orginal sirrus tyre was much lighter for descenting, i was out of gear, but with gatroskin better for hill and harder for descenting, i tried it 3 times with same result.

if i build my bike it cost me around £700-800 for the bike to be complete, well i just contacted the site and i think they shipped but i will returned and pay for the return, i do not want to build a bike with big cost but with same speed or close.

right now there is some offer for scott speeder 240 for around £500-550, i may buy it after i sort out my frame and will mount my aero bar on it and travel everywhere, or if i get some flat aggresive geometry bike will buy it and mount my aero bar, and i am sure i will go faster, because sirrus was big size for my by 4cm.

many thanks for all your advice, you know better, i am only new and never used road bike, but used hybrid for years, i am not into aethentic and looking, but rather durability, quality and speed my priority on the top list.

zindu

can you tel me please what ispeople's motive behind upgrading and lightening the bike, i know carbon frame will absorb the road, and understan the whellset and tyre, but what about lightining otheors components, what is benefit of spending more for just shiftting smother!

i totaly respect individual speciality, but just was curious why they lightining components, i thought all was about to get faster, but should be something else.

Thanks.

EKIMIKE

I'm at pains to say this and don't mean it maliciously but i think you're being a bit naive in thinking that equipment will make you substantially faster. I'd be inclined to say that poor equipment is more likely to slow you down than good equipment is to speed you up.

People choose light(er) components for several reasons. Sometimes it's not because they are light (as crazy as that sound) - sometimes for aesthetics, stiffness or even kudos. Sometimes they're simply heading for the lightest bike they can make (within their budget).

Now, a light bike isn't the same as a faster bike. Lighter bikes can be faster up hills but if you're talking 200g lighter then that's not even going to be 1 second in the real world. Also where has the weight been lost from? Weight lost from rims, tyres and tubes is likely to have more of an affect than say the weight of the frame, seatpost or handlebars. This is to do with rotational weight and laws of physics which i really cannot explain.

The one big factor you seem to be forgetting is yourself - the rider. If you want to get faster then you need to train harder/better. Do intervals, hill reps, longer rides, lose weight, eat well before you ride, eat well whilst you ride, hydrate well, pedal efficiently and smoothly, wear tight fitting clothes, use the right gears. All that stuff can really make you faster by seconds and/or minutes.

Again, riding a great bike feels great, but alot of that is sensation and therefore illusion as to feeling fast. Bike's aren't like F1 cars. Cadel Evans would have won the tour on a Specialized, Cavendish would have won the worlds on a BMC and Philippe Gilbert didn't win the Ardennes Classics because he was riding a Canyon.

EKIMIKE

My advice is: 1) Get a bike that fits you correctly and 2) focus on some of the stuff in the fourth paragraph above.

In terms of the bike - you're better to get a £500 bike and spend another £500 on better wheels, tyres and tubes than getting a bike for £1000 that has a carbon frame but wheels that weigh 2kg's.

zindu

thanks for your advice, i will post back in amonth what i idid and the result, right now i am confused do not know to build it or sell it and buy new bike ready 1,
but if i buld it i will buy pair of kysrium elite and continintal tyre either gatreskoni or pg4000s plus 65gram tube and the set will buy rival group set, but the things is, i check it some sites people swear by this frame they say 3-5 mile go faster that is why they bought it, but i amy return the frame and buy ready 1, much cheper.

zindu

Hi all and thanks for your advice and comment.

just recieved my frame today, i could send it back if i want, but i do not do that for 2 reasons;
1. it is not fair on the shop i boughted
2. i absolutely love it, it is different once you see it in real, it has razor shape, just tried it how it feels, was brilliant.

it is unique, and we never see s1 again as some one said, it is cost the company alot and they do not make profit.

i am sure it will be luxury bike, fastest on street, and comfortable.
you all right it is not all about speed but all other aspects like comfortable and psychological feeling, so whenever you cycle it will be big smile on your face not say oh! again.

already decided go with sram rival, but i am not sure about wheels, will i go for kysrium elite cost £390 or fulcrum race 3 which i can get for £310 but i like durability i am 80kg.

halford guys was inlove with it and they say they build it up for me.

again thanks to all and when i build it i will post some photos

warrior4life

Im glad your keeping it, Its a great frame and Sram Rival is a great value groupset, Not to expensive but still light and very reliable.
Either of them wheelsets would be good, Not really much between them at all, I'd maybe go fulcrum 3 just to save the extra money and put its somewhere else on the bike, A nice saddle, bars or stem.

I hope your local Halfords are good as most don't have the best reputation (although some are good).
If possible I would pay a reputable local bike shop to build it for you, Once you become a regular bike shops tend to look after you well.

I really hope you enjoy the bike and I cant wait to see pictures, Good luck with it all.

zindu

many many thanks warrior4life , you really helped, i think i am going with bb30 sram force light weight crankset and the rest rival, is that works? and i do not know what size front derailleur fit to s1 can you advice please, is it braze on, i do not know really.
and if i go for 11/28 cassett and 39/53 with midium to large cage, is it work.

many thanks for advice, it will be next few weeks until i build it.

zindu

i just foundout that s1 frame will not support bb30, therfore will go for normal gxp.

pitchshifter

@Zindu Its a Braze on fitment for the Front Derailleur.

@Warrior4life - Very interested in buying this frame. Did the 58 fit you well? What made you get rid of it? Looking at the S1 as a long term bike, if there is such a thing

zindu

many thanks pitchshifter.
i do not know what frame you are talking about with Warrior, but iam 176cm bout size 54 s1, but if you want size 58, i will try to find the site again they have only size 58 for aronud €800 or little more, if you want let me know i try if i can find it again.


thanks.

Hi all (update)

it was a big headache building and gathering all components, but just finished the build 20 days ago,

i have now 2 bikes
1 scoot speedster s40 2011
2. cervelo s1 2011 custom build.

during building and gathering components i was up and down and put it on sell even when the bike is completed, but now i am happy to keep it as i change the saddle and it is super bike and will never sell it, my scott bike is fun bike really nice bike fast comfortable, but do not like fat tube frame against wind.

my cervelo is supper fast about 7 - 7.5 kg lovely bike, not scare of wind or any situation, it only scare of traffic light positively because once you start accelerate it will not like to stop.

do i believe aero frame yes %100 is it work yes %100.

now compare speed to my first bike specialized sirrus sport and scott

scott is faster than sirrus by 5-7 minutes in 30-35 minutes cycling.
cervelo is faster than scott by 5-7 minutes in 35 - 40 minutes cycling duration.

cervelo not just fast at uphill but faster on the flat and scary descending, it is fast fast fast.

by the way i am very fit and my weight is the same.

1 thing may majority of cyclist disagree with me is i build it with flat bar and mounted clip on on it, i know majority riding in a group and going for drop bar, but remember is about comfort and fit.

i believe clip on is a magic compared to drop bar i just build it for speed not riding in a group, trust me all watching me on the road because first the bike is unique and it is really fast, in fact i am never afraid of cycling even uphill it just made it easier like a flat, and i pass all cyclist on strret whether thy have drop bar, single speed, hybrid, electric.

so sorry for the delay and i think i am now semi professional and i know which parts of the bike make you faster.
also if physical equal then the lighter and aero bike is faster any time.

i may open new topic if people request me to do it.

here is a pic of my bike and remember i build it for my taste and believe it or not, i mounted clip on on scott but it is not stable as with cervelo, and this is not dedicated tt bike but it is very comfortable as it has higher head tube. so any 1 think about getting a new bike go for aero frame you will save a big big time, not 30 second look at my finding at above, because any time i leave i look at the time for same destination place and when i arrive i look at time again, and of course the bike feels faster.
