Thanks Buddy. I finally got Giant SCR 2 for 53k. Got 10k worth of freebies as well. So essentially got the bike for 43k. I bought from Choosemybicycle.com. Great guys to deal with. Went for SCR 2 because it had super stiff Aluminium frame. I will be upgrading everything else.

Will change stem, handlebar, seat post, saddle to carbon fiber parts. Will change groupset from current Shimano Claris to Shimano Ultegra. Wheels will be upgraded to Mavic 40mm aero wheels. Tyres willl be Continental GP5000s. I am expecting a weight loss from current 11.5kgs to 8.5kgs.

That should make the SCR around 8.5kgs, very close to performance of superbikes which cost 2.5-3L. I should then ride for atleast a decade. These upgrades will be rolled out slowly over an year's time.

Upgrade should cost around 1L as everything will be brought in EU and brought my friends and family.

Over time like after 5 years i should have the funds to buy a proper aero frame made of carbon fiber and swap these high end parts to that frame. So will never be a bad investment. :-)

Congrats bro - nice bike and you seem to have a clear cut plan and over the year or so when you would finally have all the parts and then finally the frame upgrade I see you would have ridden a few thousand kms and would have lost another 20kgs or so. Man and machine both getting fitter and faster. Wish you all the best and ride safe.
