Low Mount Sliding Dropout

PM 180 and low mount can fit. Here Chromag has fit it into their Voyager sliding drops.


They sell the brake insert as 160PM but it clearly fits inside the stays with a 20mm spacer.

It’s looking good! I was thinking more about this system and realized the only part you using from Paragon’s original design is the DS UDH insert. Which is a pretty compromised design to make it backwards compatible. The adjustment is only 4mm and it’s 9mm more rearward than the original.

It may be well worth designing your own system from scratch that could be much more optimized.

Man that is sharp! Any chance you’d share the .STEP file of that code caliper?

Looking good!
I’d personally probably beef up the material around the “windows” a tad. I’ve never had a problem with the PMW stainless dropouts, but I’ve seen Ti variants of the same design develop cracks in the rib where the CS connects.

This is likely due to the hooded design as well as the space restriction on the underside of the dropout. Pushing the axle forward puts the hood inside the ‘keep clear’ zone of the UDH spec.
With the hood shifted to the outside of the dropout, clearance issues can be avoided. The tradeoff is a wider stance between the chainstays.

I believe this caliper model may be from GrabCAD. LINK
