Hey Pete - thanks for your interest!
The closest I have right now is the video overview shown in an earlier thread. We've sold many of these toolboxes since picking up the DSBP brand a couple of months ago, and I know DS Bike has sold hundreds directly with almost uniformly positive reviews (via eBay, etc.) of quality and durability. Ultimately, if you're not completely satisfied, I'll take it back for a full refund.
There should not be any interference with the mudguard at full compression, so no issues if you want to keep it installed.
Thanks again - any other questions, please let me know.
