I have 8 speed Shimano (BS64) shifters and a 105 derailleur (RD5701).

I can get a pair of Microshift 10sp shifters for a decent price.

1) Would they work with the "body" of the Shimanos, just unscrew the actual shift lever? Or, would I have to replace the whole assembly??

2) Will they work with the RD that I have??


Thanks.
