Wanted for hire/loan - Shimano 10s Kassette - 11-28 - Zell am See area

hallo, I am visiting Zell am See and am in need of a more suitable kassette for a trip to Grossglockner....I am currently using Shimano 10 speed 12 - 23, which is too grosse (big a gear).

Would anyone be willing to loan me the use of their wheel, or know where I could source a 12 - 27/28 shimano or SRAM kassette in the Zell area.

Yesterday was very difficult using the 12-23 one

I am willing to pay for the use/hire and am an experienced cyclist.

if you can help please contact me through this forum or 00447719547142

danke
