2018 Philly Bike Expo: Engin All Road Rocket – Jarrod Bunk

2018 Philly Bike Expo: Engin Cycles All Road Rocket
Photos and words by Jarrod Bunk

Drew over at Engin is a bit of a problem solver, he also happens to be a machinist as well as a frame builder creating solutions such as a 5bolt CNC Spider allows for easy access to ring swaps that the stock configuration didn’t allow, a CNC two-piece yoke that is welded together to add clearance for both 700x47c tires and a 34/50 double crank, even though this bike is built as a 1x.  

The left shifter is converted to actuate the dropper post, something that Engin thinks is going to be the next big thing to bridge the gap between an all-road bike and the MTB.  With a build of Whisky Parts Co No9 rims and fork, White Industries hubs, and a full SRAM Force 1x kit, this bike surely blurs the lines of a fast road bike that still rips off road.

  • I’m so glad you shot this bike. I was really into Drew’s description on the Engin Instagram. I also love how he machined his own spider. Pure class! https://www.instagram.com/p/Bo_4ZEIhsJ8/

    I love this bike. Drew’s crushing it lately.

  • Joey Sikorski

    This thing was even more beautiful in person. Can’t even pick out one part of the frame that stood out because all the details were amazing!

    I love the detail of the two halves construction! ho is it changing the performance?

    • Engin Cycles

      It is how the part becomes a “hollow” part. Not totally hollow as there is webbing involved.

        Thanks a lot for your answer, I got that, and also saw the holes matching ( are that threaded holes for screws? ) amazing design and manufacturing really… I’m curios about the enhancement compared to other solutions, remembers me hollowgram and similar two halves constructions… My question is regarding performance compared to regular construction? thanks and congrats for your work

          The threaded holes are actually part of the manufacturing of the part and not the assembly of the “clamshell”. The part is made from 6/4 ELI which is a very high grade 5 titanium. It is stiffer than the tube it is replacing. This part also allows for a much thinner gauge chainstay that is attached between the yoke and the drop out. The end result is a frame that is a tad heavier than tube only (although you could never achieve this with a tube) but much stronger. The ride has been all rave reviews on the mtb bikes I have been doing this for a while. Hope this helps answer your questions.

            Yes you did, is what I was thinking the higher torque strength on the bottom bracket ( like the aluminum extruded spiders from the past on mtb) looks a very neat and beautiful solution!! Nice job! looking forward for more of this innovations!

    I spotted this bike during my commute, it looks amazing in person
