Orbea Orca M-LTDi
The Orca M-LTDi is designed around two ideas, being that the amount of material typically used on the upper tubes is excessive and not enough material is used on the lower tubes. This is why the top tube tapers so dramatically from the front of the bike into a thin, light tube and down into thin seatstays while the lower tubes are massive in comparison. Less material on the upper tubes decreases the weight of the bike while the extra diameter of the lower tubes increases stiffness overall. As Orbea claims, it’s through there the majority of the rider's pedaling power is transmitted to the rear wheel.
The Orca M-LTDi also features internal cable routing, electronic and mechanical drivetrain compatibility, comes equipped with Shimano Dura-Ace Di2 shifters and derailleurs and all of this put together make a very competitive bike. If considering this bike, it should be understood that it’s a speed-specific bike and has a very aggressive riding position that may get uncomfortable on longer endurance races.
