Revelate Designs Pronghorn Handlebar Bag vs Topeak FrontLoader 12L
Two handlebar bags, measured against each other on the figures that decide whether they work on a bike.
The short answer
The Pronghorn Handlebar Bag takes weight; the FrontLoader 12L takes bar width, price and value per litre. Which of those you care about depends on the frame you are fitting it to.
Assembled from the differences below rather than written over them. Every figure is a published measurement or computed from one — nobody here has used either one.
Where they differ
4 of the 5 things we can measure come out differently.
Width across the ends
5cm narrower on the FrontLoader 12LBar bags are sold on litres and fitted on width. The figure beside each is the narrowest bar it clears with usable room either side for cables and levers — on drop bars that is what rules a bag in or out.
Weight
107g lighter on the Pronghorn Handlebar BagEmpty weight as published. Worth holding against capacity rather than alone — the lighter bag is not the better one if it carries a third less.
Price
$50 between themManufacturer's price as we hold it.
Per litre
$4.16 per litre between themPrice divided by the maker's capacity. A crude measure that still catches the case where the dearer bag is also the bigger one, which the price alone hides.
