Masi Coltellgo Please give some advice
 

Hi everyone!

I didn't have a chance to try Masi Coltellgo before i get it so I came can ask!
Please give me some advice on whether i should buy this frame or not?
I own a Fuji League which is a steel frame. I havent tried any aluminium frame before.
heard that it is stiff as hell? would that be the same on all aluminium frame bikes?
(I ride it only on road)
or should i look at the speciale sprint?
I want my next bike to be something different therefore i looked at coltello, dont have any other choices atm yet. cheers.

"Stiff as hell?"

Stiff relative to what? Your tires and saddle with provide deflection before your frame ever will.

Steel is "stiff" if it is designed to be stiff. The characteristic that makes it desirable is its damping properties... of which AL has very little.

I would buy aluminum for one reason only: weight. I don't see many lightweight AL track frames.... (nor the need). But that is just me.

generally I'd say aluminum frames have less flex than steel frames. this is of comparable prices, yes you can design an Al frame to be forgiving or a steel frame to be harsh and super stiff. but overall an aluminum frame is less flexy than a steel frame (i'd say the langster feels stiffer and a little more responsive than say a kilo tt)

Stiffer or harsher? I have never ridden a kilo TT, but have three steel bikes, one aluminum, and one carbon. I would argue that most people will never be affected by the stiffness (or lack thereof) of their frame unless they are riding a piece of trash (or they are an outlier in their body mass).

because I am only going to use it on the street, would it be suitable for the street if they are really stiff?
i was attracted by the orange colour and its look tbh, but why i saw are people using ALU frames on the street?
for example cinelli mash (i quite like it, too), has it got any similarity with the coltello? or were they designed to be less stiff to be able to cope with the road?

i have seen a few on the street and i really think it was designed more as a track bike.

design has more to do with ride characteristics than the material used. i'd rather have the cinelli for use on the road.

I can really only feel difference in stiffness and flex when i'm riding a bike back to back. if i had probably more than 10 minutes between bikes i likely wouldn't notice a difference (or it could just be placebo. in my opinion i can feel a bit more flex on my peloton with sugino 75 cranks than on my lynskey r320 with sram red crankset).

wheelset and tires will probably affect the ride more as far as responsiveness and acceleration go. i thought my conversion felt the most fun out of my friends' bone stock bikes (a clockwork and a mongoose maurice), but i put the clockwork's wheels and tires on my bike and it was disappointing. that'll make a bigger difference for most people than frame material, so get whatever you think looks best and has your favorite geometry

this frmae i think looks best(IMO) but I dont really know about geometry
currently i am riding a fuji league, geometry is : http://2009.fujibikes.com/LifeStyle/...bsolute20.aspx
and i quite like it.
now let's say i am getting the coltello, what parts will be likely to affect the stiffness most?
what should I use in order to make it more flex?
this is my first time building up a bike please give me some help
