The first time I saw an oval chainring was at the beginning of 90-ies. Five years ago I started to work on oval chainring production and since then besides oval chainri

ngs, I produce rings also for fixies. The materials are mainly aluminium and steel. Pirmoreiz es ieraudzīju ovālu zobratu 90-to gadu sākumā. Piecu gadus atpakaļ tā nopietnāk sāku nodarboties ar to izgatavošanu un kopš tā laika bez ovālajiem esmu izveidojis zobratus arī fiksīšiem. Ovālo zobratu forma ir specifiska tieši Raval. Visbiežāk izmantotie materiāli ir alumīnijs un tērauds. Pieejamie materiāli:
