First ever bike, "univega" mountain bike - this company is defunct now
- could not comment on the performane -
10 random bikes after,

(photos of recent bikes below)

Road bike Trek 2300 - aluminium frame, Ultegra Groupset, Bontreger wheels - solid wheels, solid bike,
in todays view soft and not a god power transfer, but the bike was from 2003

Next, Giant, TCR C2 - full carbon, but still soft, mavic wheels, 105 groupset
a bit of an advantage. but not much

Next (big upgrade)
Specialized Tarmac Comp 2012 frame - Sram Force groupset, ksyrium equipe wheels,
amazing performance upgrade,
switching from Shimano groupset to Sram was very beneficial,

Current:
S-Works Tarmac SL3, Sram Red (black) carbon Pro-lite wheels (with allrounderss ksyrium equipe)
Not much advantage on the climbs, big advantage on the sprints and descents
