Cyclosys Ti - Gravel Frame/Fork

5 items left


The hardest part of creating the Cyclosys was deciding how much 'gravel' and how much 'trail' to mix in to its capabilities. Make it too much of a gravel racer and it loses the confidence when the road narrows and the rocks get bigger, and of course if it is designed to excel on the roughest double track and single track it will become too sedate on the mellower surfaces. The Cyclosys is a culmination of many many variations over the years, as we have played the edges of what is capable enough without being dull. 

Tire clearance up to 700x45 or 650x52 allows for some pretty capable tires to be installed and with these types of bikes, tires define the ride. The Cyclosys is optimized for tires 35-45mm. Change the tires, change the personality of the bike.

Really, at the heart of the Cyclosys is a love of adventure and a desire to enjoy every ride to its fullest. Perfectly tuned for hours and hours of dirt roads or jamming through your favorite single track.   The newest version of the Cyclosys cannot be defined as anything other than balanced.

Is the Cyclosys perfect for a local gravel ride / race? How about ripping the local single track that has become mundane on your full suspension mountain bike? Or you scored an entry and are heading to Kansa this year? We think so...

  • Double-butted top tube, down tube, seat tube and single butted chainstay tubes.
  • Artfully tapered chain stays with massive welds at the bottom bracket for stiffness where it’s needed most. 
  • CNC tapered head tubes, custom length for each size, the inside walls of the head tube are beautifully relieved for weight savings.
  • Custom made seat tube with massive shaping at BB junction for more stiffness near BB area, again where it's needed. Running FEA tells us where we can build them up and where we can lighten.
  • Threaded T47 bottom bracket, internally relieved for weight savings. T47 shell provides a large area for the down tube, seat tube, and huge chain stays to be welded to for solid feel when hammering. 68mm shell 'external' bearing (or internal bearing with spacers.)
  • CNC custom dropouts utilizing forged derailleur hanger proven on all Turner Bikes since 2012
  • Internal cable routing, utilizing a multi-port cable guide system for mechanical or electric derailleurs, 1x or 2x chainrings, and a 27.2 dropper!
  • 3 bottle mounts:  on the seat tube, down tube, and under downtube, all welded so they will never come loose or corrode. 
  • Lunch box bosses on the top tube, welded on so as not to loosen or corrode.
  • threaded mounts on rear triangle for full coverage fenders, they are very stealth as most riders will never use them, but for the few that do need fenders... 
  • Matte polished for a maintenance-free finish, easy to touch up with a fine Scotch-Brite pad whenever you scuff it up with bags or shoes.
  • Etched graphics for long and carefree life.
  • Bolt-on head badge standard.
  • Stainless steel hardware throughout.
  • Bridgeless seat stays for more compliance. 
  • CNC machined ‘mud cutter’ chain stay bridges to help keep you moving on a rainy day, yet still provide more stiffness near BB where it’s needed most. 
  • Whisky No. 9 CXLR fork and Cane Creek 40 headset included N/C, Top bearing, 42mm x 45/45  Bottom bearing, 52mm 45/35 
  • 142x12 rear hub spec.
  • 27.2 seat post for more flex
  • T47x68mm BB shell
  • Derailleur clamp = 31.8 seat tube 
  • Headset bearings are fully integrated, 42mm top, 52mm bottom. 
  • Specifications subject to change without notice.

Turner Cyclosys Ti gravel frame/fork

The workmanship on the frame is outstanding, the metal manipulation and welds are some of the best I have seen. The completed bike handles very well in all aspects. The only drawback is my physical size is more toward an extra-small frame, but the small frame will do in a pinch.

Beautiful frame!

Received my Turner Cyclosys frame and what a work of art. Beautiful!
Great communication and prompt shipping. Can’t wait for parts to arrive and assembly to begin.

Last bike I plan to buy

I like the idea of a quiver killer. A bike to end any qualms with wanting another. I bought my cyclosys after a while of waiting and built it up (thanks to supply chain issues) Frankenstein's Monster- style with groupset mix-n-match and parts bought used from other cyclists. I'll have different configurations based on road or gravel, but the frame is the scaffolding for many adventrues to come.

Having owned a carbon bike with a much twitchier geometry, I thought the geometry of the cyclosys would be more calm and was expecting it to be a more comfortable and stable cruiser meant for many miles. But the amazing thing is that it's able to be VERY responsive without being twitchy while gaining the stability. And thanks to that, I feel much more confident in some of the more spirited maneuvering. As an aside, I really like the way the titanium accentuates the mechanical clicks and clacks of gear changing. It's not loud, there's nothing wrong, but the sound on carbon is plasticy where the sound on titanium is more akin to a precision engineered machine. Just a fun side-effect.

I'm definitely glad I waited for this! First bike build from scratch, and I hope to take care of this well enough to be the last bike build... aside from the occasional groupset upgrade and what have you.

Don't mind the weird seat post in the picture. I could only get a negative offset when I need 0 offset, so this was the best option. Supply chain build and all that -- it will be the first update as soon as the part I want is available. Even so, it rides great.

Couldn’t Be Happier!

Living in Iowa, we are blessed with mile after mile of gravel roads and gorgeous countryside scenery. I am/have been mostly a road cyclist for the past 15-20 years, but the past few years had been feeling a little left behind as a lot of my riding buddies ventured off on early morning weekday gravel rides and weekend gravel adventures. When I decided to pull the trigger and get a gravel bike of my own, I decided early on that I wanted a Titanium frame, and that I wanted to self-build the bike up from scratch.

I am so happy that I went with the Turner Cyclosys Ti!! Dave was super responsive and great to work with! He provided very helpful advice from start to finish as I planned my build, ordered all the parts/components, & assembled and fitted the bike to me for optimal performance and enjoyment.

Did I mention how beautiful this bike is? The online pictures don’t do justice to how stunning this bike looks in person! My buddies can’t say enough about how good it looks- some serious bike envy I would say! Quality craftsmanship combined with amazing, timeless looks. Hard to believe, but it rides even better than it looks! So much attention was given to the small details that Dave put into this frame to put it over the top!

Build wise - I went with SRAM AXS 1x (40T x 10/44 cassette), Zipp 303s wheels and 43mm Gravel King tires. It all came together so well – I couldn’t be happier!

Cyclosys Ti Perfection

David Turner has really nailed it with this frame design. The fabrication and welding details are truly gorgeous and the geometry is Goldilocks ideal. The head angle is just a touch slacker than many other gravel bikes on the market, with a reasonably low BB height, short chainstay, and sensible reach/stack dimensions. Combine those traits with ample tire clearance, and this bike comes alive on chunky gravel and singletrack, but still feels sprightly on tame gravel and road. And who doesn't love the silky feel of riding Ti? This frame will last a lifetime. I built up my bike with the help of Mythic Bike Works in Peace Dale, RI: Rival AXS shifter/brakes. X01 derailleur. GX 10-50 cassette. Praxis carbon crankarms. Nox wheels. Gravel King SK 43mm tires (there's room to go bigger). And other bits and bobs, with a few niblits of red anodize bling from Absolute Black and Wolf Tooth. Get one!
