Adding to Dailey's Post from a couple days ago:
A quick search through the pedalconsumption archives yields a huge assortment of Hold Fast-type straps. As far as most of these are concerned, they are clear Hold Fast knockoffs. This is a mostly comprehensive list of what the market is like today.
Archie's Grobags Strap Ons
These look sort of like a hybrid between a powergrip and a HoldFast, made by a messenger bag company. Doesn't look too secure or comfortable but the outside looks strong enough to last if you scratch up the side of your pedal a lot.
Burro Bags Straps & Burro Billboard Straps
Another strap made by a messenger bag company. The billboard straps are made with recycled velcro.
Aurora Velcro Straps
These are sort of aimed toward people who want the security of foot straps but don't want to ride BMX pedals. The outside edge is basically exposed velcro.
These are available in limited quantities from the iMiNUSD bike shop in San Jose, thick and wide.
I can't read Japanese so I don't know too much about them other than they look almost exactly like Hold Fast.
Brisbane Outdoor Strap Ons
Looks good, I'd imagine they probably feel like stiff double straps minus the cages, pretty easy to install as well. The outside edge looks vulnerable to wear but according the BO they "are constructed from a highly abrasion resistant TPU (Thermoplastic Polyurethane), which has industrial uses in inflatable boats and hovercraft bladders." A very unique design.
Simple design, easy to install, seems pretty durable but the top strap doesn't seem very wide.
BLAQ platform straps
Not that wide on the top, kinda weak on the side, but... only $30.
Similar in design to Burro, BLAQ & Phoenix.
Lookin' a lot like Hold Fast
PINZAT Power Strips
Similar to ZLDA, Burro, BLAQ & Phoenix. Made from recycled materials.
Resistant Pedal Straps
Made by a Japanese messenger bag company, looks very similar to Hold Fast.
Thats it for now, expect a post soon about the evolution of foot retention -- Cages & Straps, Powergrips, Feetbelts, Hold Fast, ?. I think its crazy that Hold Fast basically launched about 6 months ago and this many competitors in the "Foot Retention System" market have sprung up so quickly. Is this a good thing because it means that a lot of riders are getting into freestyle or a bad thing because Hold Fast isn't getting its due?
