Cervelo Building up spec & weight

Postby mosa » Fri Jan 18, 2013 21:06 pm

Just bought a S2 frame and due to limited budget i have only limited options.

Like everyone i want the best looking specd lightweight bike but cant have it all

currently have frame & possible duraace wheels which leaves me to the rest

will my bike be a heavy weight if i can only spec up with 105? Bloody shifter price!!!!!!

or if i buy 105 shifters and go for ultegra other bits will that save some weight or should i forget weight and just 105 it?

Is SRAM and option? It looks lighter and is comparable on price.

Groupset it always something you can upgrade but by bit anyway but that frame deserves the best kit you can get.

might not sit wheel with other people but you could buy a complete bike take the groupset then break the rest and sell quite surprising if your wise with your purchase how much your groupset costs you in the end?

How much weight difference is there between 105 and ultegra? 100 grams?

Newsflash 500g on a group set makes fark all difference. Stop being silly and buy whatever it is that you can afford, 105 is fine as long as its well maintained it will be very similar to Ultegra in every area.

you may find these guys useful if building a groupset but want to downgrade certain items like front mech

Newsflash, you're wrong. 500g is a huge amount on a bike. And 105 isn't 'similar' to Ultegra, I have both. Ultegra is lighter and shifts better than 105.

There isn't 500g difference between ultegra and 105 more like 100g

For the price of ultegra I would happy go with sram force. Cheaper and lighter.

105 is great set to be fair!

But do consider sram. There is also a Taiwanese brand called microshift which is meant to be quite good. Similar shifting to sram, very lightweight. They do mini groupo ie shifters + front and back derailleiurs for about £200. 100% compatible with shimano or sram drivetrain

Utter ****. It's small bottle filled with water. It makes sod all difference. You'd be talking 10 seconds difference over a 12% 5km hill according to bike calculator. And as said the difference is not even close to 500g.

The people that go to such lengths to save 100g are total cretins if they're doing it for any performance gain. Because unless you're talking about a lot of weight it's simply not worth caring about. And in this instance the bike is going to be light anyway, it just won't matter.

And I've had ultegra and found it no different. The only thing that was better was dura ace rear mech.

are you buying individual parts?

pricing on complete groupset should be way better than individually, especially from places selling oem kits

shimano da is a fair bit lighter than 105, you can cut a bit more with sram or campag, really depends what style hoods and shifting you prefer, they'll all work fine

My 'opinion' would be Campag Veloce which can be had for around £350, maybe less. Then a set of Zondas or handbuilts for similar money again.. With a view to upgrading to Chorus in one hit down the line.

That's what I would do anyways.

Campag centaur/veloce comes in much lighter and a group can be put together for less than £300 if you shop around.

See somebody above agrees!

For wheels, prolite braccianos are 1500g and can be picked up for £250.

Some people claim hand builds can be had for about £300. Not sure about weight.

Weight comparisons with water bottles are ludicrous, it's as if drinks on a bike are meaningless weight or you can somehow guzzle 100 grams worth of shifter.

Anyone who says don't upgrade now is ignoring the economic of sunk costs. When you're looking at purchasing now (heavy/cheap) vs later (expensive/lighter) it makes sense to wait for the extra money to come in. B/c ignoring re-sale, once you've spent the £170 on the 105 shifters that's money you'll never get back. If you want £220 Ultegras save for them (it's snowing anyway) otherwise you'll end up spending £390 in total.

If you want light you cannot ignore Sram. It's not a big gamble to take, you only need the rear mech and shifters. Chains, cassettes and front mechs are interchangeable. Go used Force shifters (latest ones which are all black with white graphics) and a Rival rear mech - there's only 10 grams in it between Force. All the rest can be Campag or Miche or FSA or Shimano of whatever mix you like. Good luck.

Handbuilts can deffo be had for £300. Weight entirely depends on components used to build/amount of spokes etc.

As a guide I have Ambrosio Excellight rims on Novatech Hubs with DT Comp Spoke 32/32 and they come in at around 1800g but the hubs are the heavy bit and as they are in the middle the mass just does not seem that much.

And they were under £300 and built properly by someone who knows what they are doing.

I was comparing to a water bottle because people get hung up on numbers. You don't notice when you have one small bottle on a bike. 500g is such a small amount. And as it says on that app it makes bigger all difference on a long steep hill, even less on normal hills and if you're not racing at the sharp end of uk stuff it's just not relevant. Buy the stuff for any reason but weight is the most stupid of all IMO. And marketing teams have clocked this and sell to people off the back of it.

I would suggest the most important bits on a bike are the frame and wheels. S2 and Dura Ace wheels sounds good to me. If you can only afford 105, then go with that. 500g of extra weight on the groupset isn't going to make a great deal of difference.
