Variant Maxxis Detonator 20x1.5" Silkworm plášť, drôt

CS Koupil jsem jako zadní kolo na koloběžku. Max. 65psi může být pro někoho málo pro jiného dost. Je to prostě měkčí. Nehodí se na listopadové mlhy apod. kdy je vše kluzké a mokré v ten moment totiž i na asfaltu strašně ale strašně klouže. Stejnou zkušenost jsem učinil už dříve na rozměru 26x1.5 bez silkwomu.

Variant Maxxis Detonator 20x1*3/8" B.S. Silkworm plášť, drôt

The size table for the Maxxis Detonator 20x1 3/8 tire is incorrect, because the correct one is 37x451, it will not fit 37x406!!! Don't buy for this smaller version, it's 5 cm difference! The store is misleading the customer!

Variant Maxxis Detonator 20x1*3/8" B.S. Silkworm plášť, drôt

Hello, the tire size table for Maxxis Detonator 20 is incorrect, because for 20x1 3/8 it is 37x406, in fact it is 37x451. I bought 2 tires and lost PLN 90 because these tires are of no use to me! Failure. Lost money!
