Engin Cycles Reveal Their New Seat Clamps and Tease a Future Project

Mar 2, 2021

Press Release: Engin Cycles

Amid the chaos of the last year, we’ve been fortunate at Engin Cycles to have plenty of projects to keep us busy. We’re excited to announce a new product, give updates to existing ones, and tease some very exciting projects we have in the pipes for 2021.

First is the launch of our 31.8 Engin Seat Collar, the little sibling to our popular 34.9mm version. This collar opens up the distinctive Engin aesthetic and secure, seatpost-friendly clamping to a plethora of road and gravel bikes on the market using smaller seat tube and seatpost diameters. With a low-stack, single bolt adaptation of the original design, it’s both lightweight (17-18g) and will fit a wide variety of frames. Precision machining enables a secure clamp at relatively low torque values, making it a perfect accompaniment to lightweight rigid posts and finicky 27.2 droppers alike. They’re available now in four different anodized colors with either Ti or steel bolts.

Price Update
As we continue to analyze and refine our production process, we’re now able to offer our 35MM MTB Stem at a lower price point. Stems now go for $150 with steel fasteners, and now have the option of upgrading to titanium fasteners for $180. Titanium bolts offer the ultimate in corrosion resistance, strength, and durability, all while shaving 8g of weight in the process. They can also be anodized in a range of unique colors, allowing you to set your ride off with eye-catching aesthetic detail.

Wholesale
In the early stages of launching our stems and seat collars, we’ve received huge support from bike shop employees and custom frame builders alike. As an operation born from a local bike shop, we strongly believe these businesses are an essential cornerstone of the cycling industry and boon to local cycling communities. In keeping with this belief, we have never wanted to operate as a direct-to-consumer outfit that cuts local shops out of the picture. We’re pleased to announce we are now offering wholesale pricing for bike shops and frame builders - those interested in becoming an Engin Cycles parts dealer are encouraged to visit our website here.


Process Frame Jig
As we’ve branched out to making more components, we’ve not lost sight of the fact that these endeavors came as the result of the process of making the best bicycle frames possible. Circling back to that original pursuit, we’ve been expanding our offering of products aimed at helping other builders refine their processes as well. Bringing to fruition an endeavor originally envisioned by the legendary Grove Innovations, we’re developing a frame jig that will be sure to change the game. While now isn’t the time to go into details, suffice to say this jig will offer features and degrees of precision previously unattainable. Stay tuned to our social media for more as this project unfolds.

 Aftermarket stems is a niche that needs filling desperately. Esxpecially at the $150 price range.

 Totally! Same with bars and flat pedals. Not nearly enough choices on offer *eye roll

 Agreed, but I recently stumbled across this guys sexy little Ti seat clamp and ordered one! Super exotic and he does his anodizing too. Definitely worth looking at:

 Double bolt seat clamps? Its like I've slipped back into late 90s bmx, when seat clamps weighed at least 1kg and fastened up with 3 m8 bolts... I've no idea why we were all so worried about our seats slipping?
  • 27 3
 Actually not a bad idea, given that you should (in theory) need to torque the two bolts slightly less than a single bolt clamp, and spread the clamping force across a wider area of the seatpost.

Given that some dropper posts are very sensitive to be tightly clamped there is a small sweet spot where the post will work smoothly without being prone to rotating. Double-bolt clamp could help solve that problem (friction paste can also help at a much lower cost tbf).

 Bike 'tech' isn't always the most rational stuff.... BMX might take the cake there. And I say that as a former BMX guy, that used to run those same seat clamps to clamp the bejeesus out of a steel pipe. I also had a stem with 6 face bolts.

 @Glenngineer: exactily my experience from back in the BMX days, you just have to thighten the seatpostclamp once and everything was eclipsed and the rotating problem was solved

 @Glenngineer: Yeah but a BMX handle bar has a lot of lever-arm compared to an average MTB setup, even with 35-50mm of rise, and BMX is still on a 7/8" clamp. BMX seat posts used to be 1" nearly across the board and that doesn't leave much clamping area on the circumference of the tube, add in that nearly all BMX seat posts used to be chromed steel, and you'll see why the were constantly slipping. By contrast, if you had a 25mm tall seat clamp, you get another 25% more clamping area moving from a 25.4mm seat post to a 31.6mm.

 Worked on a buddy's bike that had an Engin seatpost clamp, totally deserving of the 'bike jewelry' title. Great stuff in form and function.

 Engin Cycles is a local to me here in the Philly area. They’re based out of Wissahickon Cycles in the Chestnut Hill section of Philly. Drew is an absolute master craftsman. If you’ve ever seen his stuff in person you’ll get why it costs so much. The guy is incredibly talented and a passionate bike builder. No negative comments deserved when it comes to Engin cycles. 100% perfect. 100% hand made in Philadelphia!

 Engin is amazing. Drew is a passionate Philly bike guy who turned a crazy underdog dream into reality, a tiny shop that cranks out frames and parts without compromise. (How do I know? Because his bike shop is my LBS, which is a little bit like being able to take your beat-up old violin to Yo Yo Ma to get it tuned.) Drew is a stubborn, no-bullshit tool geek perfectionist, which means if he's willing to sell it then you can be pretty confident it's going to put a big smile on your face every time you use it for a long, long time.

 It's kind of sad that the majority of the comments do not know what they are looking at.

Those stems and clamps are designed and made In-house. It's telling that Drew – the man behind the Engin – manufactures even his own titanium bolts.

 Marketing bullshinto galore- "Precision machining enables a secure clamp at relatively low torque values..." How? they are clamping to a frame that they don't make and have no control over.

 " If the clamping force from the bolt is further away from the seat post itself, it might need less force due to leverage. If there is less force from the clamp itself against the bolt, it might require less force on the bolt too." By Engineer, Armchair.

 Well that's arguable. They are a frame manufacturer, so perhaps they are themselves clamping a frame they do have control over. Matter of fact, they are not just a frame manufacturer, but they are a frame building tool maker as well, so they have more control over the process than most. But I get what you mean. Most people will bolt to frames with varying tolerances, thrown off by paint and powder coats even more.

 Pinbike- man I really wish we could re-shore manufacturing and start making stuff in North America again Also Pinkbike- no, not like this!

 The only part of a bike less exciting than the seat post clamp is the handlebar end plugs

 I got some really nice machined aluminum Shimano Pro bar-end plugs. They were handing them out at the "Return to Earth" Premier in Virginia. My kid was super excited when I installed them on her kick bike.

 I don't understand why we don't use metal bar end plugs on any bike that could potentially go flying through a rock garden at mach chicken. They don't have to weigh that much and then everyone that runs Ergon grips won't have to find replacement end plugs every their bike falls over.
(shout out to sensus, I ate shit over the weekend and stuffed my bar end into the ground pretty good but the endcap on the meatypaw grips are built as burly as mr. Straight himself and survived unscathed.)

 I have one of their double bolt seat post clamps and it cured my slipping BikeYoke post in my ti frame. Yes it was pricey, but I was out of options to make it stop. Something about that combo just wouldn’t respond to anything else, believe me I tried. I can torque them both at ~4.5nm and no binding of the post and no slipping in the seat tube. YMMV

 Straight tapped seat post collars that don't allow for bolt deflection as the clamp tightens tend to bind up. Most clamps that cost less half this amount compensate for this with a floating nut, that's not made out of aluminum. Why would anyone buy this?

 man that's a long press release for a stem. I'd be super interested if they'd make one to match my matte slate ck hubs, though!
