A corey racing geometry, almost uncomfortable hardness on the saddle - the carbon frame of the Oxygen looks a little out of date and deserves a makeover. However, it should be possible to find equipment variants in the modular programme of the mail-order company from Bad Honnef that would make the bike more comfortable. There are no objections to the complete Shimano 105 groupset and lightweight wheels built by Poison. The voluminous aluminium handlebars with their extravagant shape feel better than initially thought. Until a year ago, the Ultremo ZX was the top tyre in the Schwalbe range and offers good riding characteristics. However, at 1,600 euros for the equipment on offer, the Oxygen is not a bargain, as you might expect from a mail order company.
