ISP vs SL2 - Advice Needed


gyro

Recommended Posts

If you want a really comfortable bike thats also very stiff get the roubaix SL2, you'll never look back.  I got the Roubaix Pro (only difference is the SL2 is a bit lighter) and its great, the Tarmac version is lighter with a bit more of an aggresive frame geometry.  Either way go Specialized!

I have the SL2 and dont find a problem with the ride quality in terms of the ride. I have gel under my bar tape as well as a Fizik saddle. I know the specialised saddle gives it a more harsh ride feeling, but with the Aliante i have no problem.... smooth like a babies bottom... and no need for a Assos :-) I also had a bike setup done by Jeroen Swart... He is brilliant!!!

 

I had 2 options... SL2 or IPS. The SL2 was less expensive and a current model Race Horse horse

I've got the phenom sl saddle from specialized and I agree it does make the ride more harsh compared to the Fizik aliante I used to have.  The problem I found with the Aliante was that after the 2.5 hr mark in a ride it broke my ass which the specialized isn't doing.  The Fizik is now on my spinning bike.

My frames cracked - need to replace it.  Have narrowed it down to Giant Advanced ISP and Specialized SL2.  Can't make up my mind which one.

Any advice appreciated.

 

Thanks

Thanks guys - I went with the SL2.  Can't say that i'm sorry after a week of riding (including racing).  Initial feelings are that that front end is very stiff.  overall it also feels stiffer than my old giant tcr yet more comfortable - i think the word is supple.

Hmm washed my bike over the weekend and discovered a crack on the new frame Shocked   Above the front derailleur, behind the seattube.  In fact that whole are behind the seattube feels really softConfused.  I checked with buddy who has same frame and his is not like that.  Frame is currently at LBS waiting for the agents inspection.  LBS agrees it's not normal but apparently Specialzed has very laborious warrenty procedure where a report with pics first has to be sent to America for approvalConfused.  So hoping to hear back today from them.

Wondering if I made the right choice?!CryCryCry

Both the SL2's I know of is relatively small sizes.I just asked to see whether the bigger frames is included in this "cracking" dilemma.Wonder if it could be the way these frames gets made that could be the cause of the problem.

Big deal, when you are still on it, and it's still strong in 5, or 6, or 10 years then you can say something...

 

Scandium Pinarello is coming for 5 years now and is as perfect as the day it was made.

So you broke a frame in a month. That's not nice. Maybe it's a repainted Cerv?lo.
