Tri Drybag

The Topeak Tri Drybag Large is a 0.72 L top tube bag with a padded, waterproof main compartment that keeps contents dry, safe and secure. The Tri Drybag is made from waterproof nylon fabric with sonically welded seams and straps on in two positions.

Who it's for

Riders who want bars and small essentials within reach, and want them to stay dry. The Tri Drybag mounts quickly to the top tube, so food, phone, wallet and tools ride right in front of you.

Fitting it to your bike

Nylon straps hold it to the top tube and head tube, with two possible positions to pick from. It fits a top tube of 38–52 mm and a head tube of 44–75 mm in diameter, and the bag measures 18 x 12.8 x 4.7 cm.

Capacity and what fits

0.72 L in one divided, padded main compartment, at 120 g. It is good for a mobile phone, energy bars, wallet and tools, with the divider keeping things apart.

Weatherproofing

The fabric is 420 and 840 denier waterproof nylon, and the seams are sonically welded. The main compartment is waterproof as well as padded.

Looking after it

Grit, mud or a badly packed bag can dull or scratch paint where the bag sits, so fit foam covering or protective film to the frame first.
