Thanks Balu & Pradeep for your inputs :)
Yes I will do more research on Carbon frames.
My usage is typically between fitness and competitive(mostly).
I have been riding mostly in Ahmedabad(Gujarat) but I do travel to Bangalore a lot for work. Currently I haven't tried any of these bikes, I might be able to try them may be next week or so.
I have seen both the bikes in Ahmedabad and I am getting a deal of around 85k for Reacto 500 and 1.3L for Reacto 5000, though the difference is only the carbon frame. And this is why I am confused.
Also I don't mind buying from Wheelsports, it has a good repo and I trust Wheelsports too :)
I would like to talk to them, do you guys mind sharing the contact details if you have?
I am still open for suggestions and advice from all the pros in this group :)
