Alpine climbs will never be that difficult anymore. absoluteBLACK is the only company on the market making 46/30 and 48/32 chainring combinations which fits 110/4 Shimano cranks. Its patent pending solution solves a long felt need for such chainring sizes in modern 110/4BCD cranks.
IMPORTANT: Due to very special offset construction and custom bolts: *30T can only work with 46T and special bolt set 46/30. (bolts included with small ringS 30+32T) *32T can only work with 48T and special bolt set 48/32. No other combination or mix will work.
