Specialized Bennies Platform Pedals Toeclip Adapters

I am continuing to try out different platform/flat mountain bike pedals that can accept toe clips (with or without modifications or adapters).  The Specialized Bennies platform pedals are fairly well reviewed and look like they are quality pedals. I have had good experiences in the past with Specialized components. So, I made these toeclip adapters and I am trying out the pedals.

The adapters mount on the pedals without any modifications to the pedals. However, I typically remove the bottom side studs/grip screws. When using toe clips, you don't need the studs on the bottom side of the pedals; thus by removing them, there is less of a risk of them scraping up your leg in an accident. Also, by removing the bottom studs, you then have spare studs, if needed.

Besides the adapters and toe clips (I prefer Zefal S/M half clips – no strap), you will need the following hardware (stainless steel is preferred): 

• 4 - M5 x 35mm screws (I prefer hex cap screws)
• 8 - M5 washers
• 4 - M5 lock washers
• 4 - M5 nuts

M5 is the best fit for these adapters, and for most toe clips.

The models are best printed in the orientation that they are downloaded. This is not the orientation that the adapters fit into the pedals. See photos for correct orientation (it's easy to figure out, but note that the back pieces slide into the pedals from the side). No supports are needed. Do not worry about the thin walls created by the screw holes on the back pieces; they print fine, and the presence of thin walls does not play much of a structural role.

I printed my adapters as follows:

• 0.4mm nozzle
• 0.20 layer height
• PLA
• 3 walls and bottom & top layers
• 100% infill w/ 2.5mm brim

At the above settings, my full set of adapters (two front & two backs), used 45.34 grams of filament, and the total print time was 87 minutes (including warm-up & calibration).

NOTE:     The Back adapter pieces install from the side of the pedal. They are inserted in the side opening.

NOTE:     When attaching toe clips (make sure you install the clips in the correct orientation for the R & L pedals; it's easy to install them upside down). Removing the bottom grip studs/screws before installing the toe clips is easier on the hands. You just need to make sure that you have the correct front faces of the correct pedal (R vs L) in the correct orientation.

NOTE:     Because platform pedals are typically large, in most cases, a small/Medium toe clip is easily long enough, if not too long.
