Cyclosys Ti - Gravel Frame/Fork

Polished and etched
1 item left

The hardest part of creating the Cyclosys was deciding how much 'gravel' and how much 'trail' to mix in to it's 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 of 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.  Flip a set of 35mm full knobbies on it and hit the cyclocross race, 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...

Turner Cyclosys Ti

Living in western MA, my cycling group rides mountain bikes in the fall, winter and spring, changing over to road in the summer months. Over the past 5 years, the road has become gravel. As mountain bikers, our typical gravel rides will include as much mellow single track as we can find. My first gravel bike was closer to a road bike with clearance for bigger tires. For my new gravel bike, I wanted a bike that was a jack of all trails and that struck a good balance between the single track and the road. The Cyclosys Ti meets my needs perfectly. I love the ride of Ti and the bike has a great blend of compliance and responsiveness. The frame is stiff enough that it climbs really well but is still comfortable. The bike is very composed on single track and is an absolute blast to ride on flowing, twisty trails. I had high expectations from Turner's reputation for making great riding bikes and my expectations have been met fully and surpassed. This was the first time I had assembled a bike from scratch and with all the advice I got from Dave Turner, it made my project an absolute pleasure.

Ti Cyclosys is a winner

My Cyclosys is number 12 and this is my fourth Turner bike (no, I’m not related to Dave). I own aluminum and carbon bikes (and other brands) but never previously bought titanium. Researching for a Gravel bike, I compared numerous manufacturers. Fortunately, Dave brought out his new model just before I purchased another brand…I am so glad. The Cyclosys is just quality, quality, quality. My engineer buddy marveled at the stacked dimes and precision construction. It really is a beauty, tubes sweep elegantly, all internal cable routing (some brands can’t handle full internal routing e.g. to the rear mech, but Turner can). My biking friends gloat and my neighbors constantly offer compliments - more so than my other bikes. GRX2x11 was my preference with Ritchey touch points and Hunt wheels. I would need to test another Ti bike to make accurate ride comparisons, but like my previous Turners, this large fitted me so ‘right’. Floats over bumps, springs up hills (unlike my legs), and changes direction without the need for thought. It’s simply superb. Roll-on summer’s post-Covid gravel races.
