Revelate Designs Mag Tank 2000 Bolt-On


Product Overview

This is the bolt-on version of Revelate's super-sized Mag Tank, ideal for bikes with a pair of mounting bolts on the top tube.  The Mag Tank 2000 is named for its ability to carry up to 2000 calories!  That's a lot of food!  Stuff it full of snacks or anything else you need to keep close at hand.  The tapered shape maximizes volume while maintaining a low profile for leg clearance when pedaling.  The flap lid and magnetic buckle provide easy one-handed access and secure closure. 

This bag is designed to shed dirt and water but is not waterproof.  Best to keep sensitive items in a dry bag.  The lid will not open accidentally but small, loose items (single keys, individual M+Ms, tiny precious gems, etc) could escape the flap when riding over rough terrain or laying the bike on its side.  Keep your small valuables in a ziploc bag or other container. 

Fit Notes

We especially like this bag for drop bar bikes, MTBs with very short stems or other setups that don't/can't use Revelate's Feedbags or similar bags that attach at the side of the stem.  The wide front of the Mag Tank 2000 can interfere with Feedbags, limiting your ability to turn the handlebars to extreme angles.  This is rarely a problem at normal riding speeds (other than the tightest of switchbacks) but is inconvenient at other times and puts undue strain on the sewn attachment points.  Unless you're running a fairly long stem (>90mm) we'd recommend the standard Mag Tank for use with Feedbags.
