perfect ... as should be expected!

i don't buy anything on eBay*.

*except vintage '50s Danish furniture.

i think the 520/hi-ten debate is psychosomatic and if one did a blind test (the was properly controlled ... making a hi-ten frame look like a 520 frame) that i would wager that the riders couldn't discern between the bikes above random chance.

i can't believe that a bike company hasn't done this ... maybe they have and came to these results, which will never see the light of day

edit: i paid £295 for the Mango ... the bike you linked is £450
