It was two years ago when I purchased the items, so I'll do my best attempting to recall exactly what I bought. I definitely bought the racks from twistedthrottle.com and according to their web site, I purchased the following items:
SW-MOTECH Alu-rack Toprack / GPT.05.299.100 for $119.99 plus the SHAD topcase adapter for $35.
SW-MOTECH Quick Lock Sideracks / KFT.05.067.100 for $299.99 plus the SHAD sidecase adapters for $49.99
Then, I ordered four (4) SHAD cases from adventuremotousa.com as follows:
SH42 (3 ea) 2 side cases and one top case (for my extended trips)
SH25 - a very nice & compact case for daily use (barely holds my helmet & gloves)
Another nice feature with the SHAD products is the ability to easily swap the guts from the key locks, so you can lock/unlock all of the cases with a single key. Anyway, like I said, I've had them for 2 years and they're holding up extremely well. I've traveled 600 miles in a day, averaging 75-80 miles an hour with all 3 of the SH42s attached without any problems.
I use the SH25 just about every day to carry my lunch and odds & ends to work. I've done 90 plus with it attached and never encountered a problem. Several of my riding buddies have purchased the SH25 case after seeing mine and seem very content with the product as well.
BTW, the guys at adventuremotousa were easy to deal with and even gave me free shipping for purchasing the SH42s as a complete set. Perhaps if anyone else is using SHAD cases, they can share their experience as well.
