Final yr, I made a visit all the way down to San Diego to go to the manufacturing facility for 5DEV. As a result of I’m native to them, they reached out to ask me to their facility to attempt a prototype of their new gravel cranks… and so they mentioned that they have been going to chop them on the CNC machine whereas I waited.
Um… yeah, thanks!
5DEV is the youthful bike division of a bigger, and extra established machining firm referred to as fifth Axis. fifth Axis is a frontrunner within the manufacturing of advanced elements for the aerospace and medical industries.
The co-founders of fifth Axis/5DEV are cyclists which were mountain biking for over 30 years. With the scarcity of elements in the course of the pandemic inflicting big wait instances to obtain new elements for his or her bikes, they determined to start out constructing their very own stuff.
All the merchandise 5DEV gives are designed and manufactured in-house out of aerospace-grade billet aluminum utilizing a patented tooling system utilizing environment friendly processes whereas managing the design and building from the begin to the end.
Once I acquired all the way down to the San Diego space, I met Will Talbot at their facility, and we began the tour.
The 5DEV Manufacturing unit Tour
The ability, though neat, clear, and fairly organized, initially appeared like a typical, albeit, high-end machine store. As I walked by way of the 5DEV workplace space the place I acquired to fulfill a few of the behind-the-scene 5DEV crew, I began seeing bits and elements that I really acknowledged… in different phrases, bike stuff. This was going to be enjoyable.
We walked out of the 5DEV workplace space, and again into the store. We wound our manner by way of a maze of (what appeared like) numerous CNC machines to get to the one that will be chopping the brand new cranks.
5DEV did a lot of the machining on the pair of crank arms that I used to be to take residence previous to my arrival. As soon as I acquired there, they put them again within the machine and let me watch them end the method.
The crank arms went into their fifth Axis proprietary tooling and so they queued up the machine. It was enjoyable watching the CNC machine do what it does, placing the ending touches on the cranks.
The machine effortlessly reduce the ultimate form of the arms whereas smoothing the entire edges, and threading the spots for the chainrings and pedals. It actually didn’t take lengthy in any respect.
I acquired the arms proper off of the machine and shall be utilizing them on the bike as they’re, with the uncooked aluminum and no end. They’re as fairly as they give the impression of being in particular person.
5DEV Cranks On the Bike
The prototype Gravel Cranks us the SRAM 8 bolt sample to connect the chainring, They didn’t have any chainrings for these cranks once I acquired the arms, in order that they despatched me residence with a set of their Path/Enduro cranks and their 12% oval chainring for my Surly Krampus (that I introduced with me).
However there are two chainrings out there on the web site now, referred to as Street Gravel Basic Chainrings in 40t and 42t.
Precise Weight
Each the prototype Gravel Cranks and their Path/Enduro Cranks are manufactured from 7075-7651 billet aluminum. They’re constructed to be each gentle and powerful. The Path/Enduro cranks weigh in on the claimed weight of 525g (w/ 30mm spindle) with the Gravel Cranks weighing in at 491g with a 29mm spindle.
There aren’t quite a lot of beauty variations between the 2 totally different cranks. However, upon nearer inspection, you’ll be able to see the delicate variations between the Path/Enduro and Gravel cranks.
The Gravel Cranks have barely extra refined corners and further chamfering on the sting of the arm going additional up the arm from the pedal to in direction of the extraction bolt. Plus rather less materials across the base of the arm (on the extraction bolt) on the Gravel Cranks. These few areas of eradicated materials are the supply of the 34g lighter weight distinction on the Gravel Cranks.
They each use Chromoly metal crank bolts with self-extracting {hardware}. The Path/Enduro in addition to these Gravel cranks include a 5-year guarantee.
5DEV Path/Enduro Cranks
The Path/Enduro cranks that I put in on my Krampus have been put in with no hitch. I’m nonetheless utilizing the Race Face backside bracket that was on my bike already, and with a single 2.5mm spacer on the non-drive facet, and the chain line was excellent. I’m working the 175mm crank arm size and their small 12% oval, 28t chainring (outdated knees and occasional bikepacking masses) with a Shimano XT 11-46 cassette.
Since I’ve put in the Path/Enduro cranks on the Krampus I’ve put roughly 500 miles on it within the final 6 months. In that point, I’ve not had a single problem. The alloy bearing pre-loader that comes with the cranks, hasn’t loosened up over time, like others that I’ve used previously.
The cranks don’t really feel like they’ve any lateral or “noodly” motion. They really feel stiff, whereas delivering the facility on actually laborious efforts, and really feel gentle when spinning. They usually look superb.
The aesthetics remind me of the aftermarket “blingy” crankset choices that have been in abundance “again within the day”, just like the Kookas, Hersheys, and Cook dinner Brothers, besides that 5DEV will get it proper. Like actually, actually proper.
5DEV Gravel Cranks (prototype)
The Gravel Cranks I acquired to check, have been introduced residence to make use of on my gravel bike Dream Construct. They turned out to be the right cranks for the Masi Incanto Ti. They actually popped on the construct, being a spotlight on the completed product.
These cranks have a 170mm arm size with an 8-bolt chainring mounting interface which shall be on the manufacturing cranks. The Path/Enduro cranks have the extra frequent 3-bolt interface.
In the intervening time, I’m utilizing a Wolf Tooth Powertrac Elliptical 38t chainring with it.
The construct was accomplished again in early December 2022, and to this point I’ve about 300 miles on these cranks. They’ve actually been flawless. The end on the uncooked aluminum I acquired has remained un-scathed even with a 25-mile mud-fest I’ve performed below their belt. Up to now, they appear to be holding up very well.
