Поразила стоковая комплектация карбонового подвеса алюминиевыми подседельником и рулем.

Заменил кассету на SRAM 990, цепь на SRAM 991. Хотел заменить систему на Truvative Noir и передний переклюк на SRAM X9, но не получилось У системы и переключателя оказались новые варианты крепления. Подскажите, существуют ли реально осуществимые варианты решения этих проблемок?
