Crashed. I thought I escaped unscathed but turns out I broke the plastic lid and from a vintage bike there's no one selling the entire combi levers or just the lid itself. (in shops locally, I saw on ebay but with shipping, it aint worth the cost) It's on a 3x9 speed XC bike with XT parts ..

friends are egging me on for a 10 spd upgrade but I am not ready to shell out more cash on a 2 week old (2nd hand bike)

what do you guys think I should do?

fyi my combi levers look like this http://www.ebay.com/itm/VINTAGE-SHIMANO-DEORE-XT-9x3-BICYCLE-SHIFTERS-HYDRAULIC-BRAKE-LEVERS-M765-/151247697679
