Information about Shimano bicycle parts is displayed in a spreadsheet type table accessed from the Shimano Web site:
When this site is accessed, basic navigation data is rapidly displayed but spreadsheet table data is delayed about 30 seconds before formatting into a table. Not a bug, but minor irritant when compared to my iPad’s Safari browser which displays the table almost instantly.
