Have just been outside with the weighing machine.
Orange P7 / Rohloff / Hope Tech M4 / Fox Vanilla / Thudbuster = 34.5lbs 😮
Orange G2 / Singlespeed / Hope Mono Mini / Rockshox J2 = 29lbs (y)
5.5lb / 2.5kg of way too much weight somewhere.
The difference in the two is night and day when lifting and riding. It it so surprising that 2.5kg (a Camelbak of liquid and a bag of goodies etc.) can make such a difference. That the weight on the P7 is all on the rear axle doesn't help much as the bike is so unbalanced.
Still, as mentioned above – it all helps with the fitness training 🙂
