iSSi Announces New Thump RP Composite Pedal

Jul 17, 2019
by Chris Duerkop  


While initially introduced as an SPD-compatible clipless pedal brand, we have been hard at work adding more and more pedals to our line. Our first foray into platforms started with the high-end STOMP, a fully machined aluminum pedal with a BIG platform. We added to our flat pedal lineup back at QBP's Frostbike event in February 2019, introducing our first all-composite flat pedal, the THUMP. This month, we released a complementary metal pin version, the THUMP RP (replaceable pin).

With the Thump pedals, we further commit to providing a concave shape to the pedal body, rather than a thin profile. The 18.5mm thick pedal body has 2.5mm of concavity in the middle of the pedal, creating a stable cradle for the ball of the foot for great control and comfort.

Not wanting to leave small-footed riders behind, the Thump is offered in a "standard" sized platform (119 x 99mm) as well as a smaller version (113 x 95mm). Clearance-conscious riders may also opt for the smaller version to avoid catching the pedal on rocks.

The pin height can also be customized according to rider preference. Pins are effectively 3mm tall out of the box, but riders may choose to remove the back-side washer, making the pins a much taller and grippier 5mm.

Tech details:
• Tough nylon composite body
• Chromoly spindles, sealed cartridge bearing & nylon bushing
• Body: 18.5mm thick, 2.5mm of concave
• Platform sizes: standard - 119 x 99mm, small - 113 x 95mm
• Available with molded nylon pins for casual rides or replaceable steel pins for greater traction
• Pin height: 3mm out of the box. Remove the 2mm washer under the pin head to convert to 5mm pin height.

 Had a set of their high Q factor trail pedals. The clip mech broke on both, never got a reply from either Issi or Quality Bike. No thanks, on to the next.

 I broke a couple of sets and moved on. But the idea is sweet!

 Am I missing the fact that they give all relevant information EXCEPT the weight ? !!! Lame....

 Ah yes, another tiny platform pedal. I guess the market has smaller feet than I do... I see these and all I can think about is foot cramps.

 I demoed a pair of Issi trail SPD pedals and found them to work counter to what I was after; they were easier to clip out of and harder to clip into than my XT trail pedals I had been using up until that point.

 Just bought a pair of these, they are fantastic! They are almost like composite DMR Vault pedals.

 These look good but you can get equivalent for much cheaper if you look in the Bmx section on your online retailer.

 The Odyssey Jim C's come to mind or the RF Chesters.

 Why do they all insist on calling them composite or nylon instead of just saying plastic pedals are now $50?
  • 18 0
 ...because a composite material is more than just plastic...there is likely ground up glass fiber in the nylon...thus making it a composite material...and not just nylon...which would be just plastic...pretty simple...

 Its most likely something like PA66-GF30 (or PA66-GF35) which is glass fiber reinforced polyamide where up to 30% (or 35%) by weight is the glass fibers. Making it pretty far from "just plastic" by both composition and mechanical properties.

 @patdinho: hey you know what? Cool. I learned something new. Nylon= plastic but composite nylon = plastic + glass. Thanks

 @speed10: that's what composite means: a composition of different materials.

"Announcing", though, is a little bit of overkill for pedals to my taste. It's not the queen of England whom you need to announce.

 Plastic pedals, plastic cranks, plastic bike, what could go wrong?

 Are resultant injuries fixed with plastic surgery?

 I actually remember thinking plastic would be a good meterial for pedals, and here we are.
