i have no idea to what you are referring... but for the record my b123 36cms are not working for me (long rides are giving me chest pain) so i'm in the process of ordering parts to replace (i'm switching to 019s or 021) and just ordered a new stem though i must say *thread jack starts here* it really pisses me off when sellers have statements like "buyer must pay within 10 days of close of auction" then when you pay the same day the auction closes and you still haven't heard from the guy 6 days later.... i'm gonna give him his ten days but for real...
back to the original topic... do the beer shim till you can get a sweet deal on a stem
