comparing different brand measurements

[briztoon]

Hi guys, I would like some help please.

I currently ride a Specialized Tarmac SL2 size 56 and I am trying to workout what size Wilier Granturismo would be close. I am having a little trouble understanding and comparing the geometry between the two different frames. Below are links to the two bikes.

Wilier Granturismo

Thankyou for your help.

Have a look at this:

bike-geometry-comparator

there is a lot of detail but its pretty cool the way it will layer the two frames over each other so you can really see the differences

Really, comparing brands is one thing but the more important measurements are you and your contact points. Height? Inseam? Saddle setback and height? Saddle-handlebar drop? Stem length? This is what fits you on the bike; the other important geometric things you can't really compare without riding the bike since Wilier is not forthcoming with wheelbase, rake, etc.

Thankyou for your help.

The three most important things in frame dimension is seat tube ANGLE, top tube length(virtual since these are slope-y) and head tube length.

You are right, you are between a L and XL for the Wilier. I guess it depends on how you fit on the Speciaized and if you are using a long/short stem, saddle in the seatpost-fore-aft, want a more upright or lower riding position, etc.

I would use these meausrements as most important -
1) Distance from top of saddle to center of the BB. Is the seatpost extension reasonable and safe?
2) Vertical distance from the top of saddle to top of handle bars.
3) Distance from saddle (nose? center?) to the center of handlebars next to the stem.

Is the dealer willing and able to change the stem to provide the fit you want?

Is it possible to ride the Willier? I'd demo the sizes nearest your Tarmac and go from there. Make adjustments or change the bars, stem, saddle, blah, blah.

If not, look up the size Willier recommends for your inseam. You can change saddles, bars, and stem to find the best, most efficient, and closest to the Tarmac fit possible. If the shop isn't willing to change at least the stem for you, then you need to look elsewhere.

I've always found geometry measurements pointless until I ride it.

There is only one Wilier dealer in my state, in a town about one and a half hours away (and I don't have a car). And they only have one Wilier Granturismo in stock, a large, and it is expensive at $7k.

This is only a dream bike for me. If I get a chance I would live to try and take the Granturismo out for a test ride. I just wanted to know if the bike was close in size to my current bike, before I thought about making a trip.

It may be possible to import a frame and forks for much (much) cheaper, and I can try and find a LBS that will do a build for me. There is much more for me to investigate, before I even seriously think about this.

$7k USD? Are they flippin insane?

Only poor part is the wheels, which you could easily sell off and cover the price of some rims for a set of handbuilt wheels. And if you did manage to get a frameset ($2350 at CC) with enough ebaying/bargain hunting online, you could probably get it built with full chorus with the cassette/crank of your choice, in addition to your preferred handlebars/stem/saddle. Really, I'm shocked anyone could even build that frame up to $7k, I'm assuming overpriced carbon tubular machine built wheels or something similar.

Hi, I ride a 2005 Specialized SWORKS E5 size 56(Large). Last year a I bought a Focus Izalco size XL. The focus has a slightly longer top tube. So I have a 120mm stem on the Specialized and a 110mm stem on the Focus.

Your bottom bracket(BB) is your reference when transferring your bike positio/setup from one obike to another. To transfer my set-up to the Focus I measured the seat height(top of seat) from BB centre along the seat tube. Then measured the horizontal setback of the seat nose from the BB using a plumb bob and ruler. Do the same setup on the new bike with the same saddle. Then set you handle bar height and reach with reference to the seat nose.

If you use the same saddle on all bikes then this works really well since you will have a natural resting position when sitting on different saddles.

I have used this method across all of my bikes, steel commuter, alloy trainer and carbon racer etc.

Sorry, I am in Australia. But in my searching I did come across the Competitive Cyclist site and saw the Gran Turismo options there.

This is the bike in question, GRAN TURISMO.

Though quite a few LBS down south (by a couple of thousand kilometres) have WILIER GRANTURISMO / ATHENA (2011) that range in price between AUS$3900 and AUS$5500 depending on what wheels, seatpost and handlebars they use.

I think I will visit two LBS I know that may import a Wilier and ask them to quote a price for a specific build.

De Grandi in Geelong are the Australian importers of Willer

 

[briztoon]

SO does this mean they supply all the LBS in Aus. with Wilier? and can you buy direct from them?

As I've said countlesstimes I'm new to cycling, so don't know how everythings works in the industry.

If you want to know weather or not a frame will fit you all you need is stack and reach (vertical and horizontal distance between bottom bracket and the top of the head tube/head set). Everthing else you can fix with offset seatposts, stems, etcetera.

How the frame will handle is another matter for which you need greater expertise than mine or, better yet, a test ride.

LBS close will most likely have an account and should be able to buy, they are also the Campag, Fulcrum and Pinarello importers

Should note that maybe not every LBS will be appropriate...

Edit:
Also note they do sell mail order, so you could buy direct, but they will most likely be the same price as a local, and at least then you have close support
