Is this something I can youtube and get done without too much hassle? the laces are loose and I am not exactly sure how to get them tightened correctly. Would prefer to relace while I am at it. or is relacing a bigger project not meant for newbies? it is a Vinci BV1929. If I cannot tackle I guess I will need to search around for a local expert. I want to make sure it is done correctly. Thanks
