ContinentalUnisex Adulto Reifen-1012432600 Pneumatici da bicicletta, Nero, 0,6 cm/24''

My lad could barely pedal his bike in the lower gears, couldn't get into the higher gears. His Cuda bike had big knobly tyres. These, tyres, have transformed the bike. Very different rolling resistance. He flies along now on tarmac roads, his confidence has increased on tracks too. They grip well in rain, grass, dirt and mud. Not bad in sand but still hard for him. Great price and arrived quickly. The sidewalls feel extremely thin but seem to be holding up very well. No negatives at all. Thanks.
