Timmy's Body Geometry Bike Fit...

Fuck you Timmy, I don't wanna charge you shit. I'll work on a referral process. It'll be good practice anyway.
I'll be better equipped once we get the new shop. But I can do it now.

Bring both bikes in some time.
Some points to make.

• Both bike ARE completely different, ie different materials and different geometry so you can only do as much to set them up similar, they'll still handle and feel different no matter how much you do.
• Umm hang on I think there was more points.
• Your Specialized frame has a 73.5degree seat tube and head tube with a 40mm Raked fork. This will handle dramatically different to a Colnago which for a similar size has a 73degree seat tube but a 72.13degree head tube with a 43mm raked fork.
• This means the trail of each bike is a world apart. Put these figures into a TRAIL Calculator.
• http://www.kreuzotter.de/english/elenk.htm
• The head angle is first 72.13 for the Colnago and 73.5 for the Specialized
• Then the wheel diameter 67.8cm (typical for most 23c road tyres.)
• Then the fork rake 4.3cm for the Colnago and 4.0cm for the Specialized.
• The Colnago has a Trail of 6.4cm the Specialized has a trail of 5.9
• These figures basically give you a true reading of the stability and responsiveness of each bike.
• The lower the figure the more twitchy & responsive a bike is.
• The higher the figure the less responsive and more relaxed a bike is.

That is why I think a Specialized Roubaix bike would be Puuurrrrffeeect for you.

Your Colnago has a long wheel base as it is designed as a bike to be good over long distances and rougher roads. The downside of this is the sluggish and relaxed steering. Which makes it less versatile for shorter racing with more corners etc. i.e. Crits.

Where as the Specialized Roubaix is a world apart from it's brother the Allez. It has a wheel base of 1010mm (5mm longer than the LONG Colnago. ) and 27mm longer than the Specialized Allez you currently ride.

BUT!!! And here's the biggy. The specialized has a 72.5degree head tube, similar to the colnago, but has the new custom made 49mm Rake forks that Specialized make themselves. In the past forks have only been available in 40,43 & 45mm, limiting the head tube and handling of frames.

So the Specialized Roubaix still pulls out a Trail figure of 56mm meaning it will handle as well as any bike (my tarmac is also 56mm trail) around corners but still be long and compliant over the longer rides and rougher roads.

So here is a bike that can be raced in crits and can be competitive, is light (lighter than my Tarmac), still extremely stiff in the BB and Torsionally stiff so that it corners well, but being a long wheel base and carbon will be super comfy and compliant on long rides and rough roads.
In a 56cm this frame weighs only 1065grams (1455gram including fork!!)

This frame is also the only frame in the Specialized Range that Shares the super expensive E390 Carbon that is also used exclusively on the Specialized Tarmac SL. For interest sakes my Tarmac uses the cheaper E294 Carbon and most carbon manufacturers generally use the cheaper again E240 carbon(Also known as T700 carbon which is the widest used carbon in the bicycle industry.).

The roubaix also features the Zertz dampening in the fork, handlebar and seat tubes. Making it their best combination of compliance, weight and stiffness. Over 50% of the Gerolsteiner Team ride the Roubaix, MORE than ride the SuperLight Tarmac SL.

Also the roubaix has an extended head tube so that handlebar can be a little higher without the need of a stack of spacers.

Gunsle-Doesn't like to hard sell but thinks Timmy is a major candidate for a bike more suited to his needs.
