I haven't gotten it built yet. but the geo and clearance is spot on as I would only expect from a DT pedigree. Super excited to start ripping it next week. Dave answers the phone and communication is outstanding. Customer service through the roof. I've been off and on Turner Bikes for 25 years! Im sure this one will not disappoint. DT is a mtb legend.
Terrific bike! Road, gravel, commute - You name it, this bike does it. Supple, comfortable and fast. I use this bike for everything. 6' with a size large. Fits perfectly.
I have been riding road bikes for close to 50 years and have had more than my share of great steel bike (Columbus, Reynolds 531 and 753) and have really enjoyed all of them. Around 2010 I moved up to a Look carbon and then to a Giant TCR, all great rides. Then I heard about "endurance" type bikes and the benefits of a more relaxed ride for older riders. I have known the Turner crew for many years and had purchased some the MTB bikes and loved the quality of those bikes. A loyal Turner employee Greg Wulff suggested a Cyclosys Ti and after some serious consideration I pulled the trigger and man am I happy I did. I had it put together with Shimano di2 11 speed, 50/34 crankset, Knight carbon wheels and Continental 32mm GP5000TR set up tubeless, WTB saddle, carbon seat post and Cadex 46cm carbon bars and stem. Well, here we over 5,000 miles later and I still love it as much as the first day I rode it. The ride is so smooth, and the geometry is absolutely perfect for my longer endurance type rides. I would do it all over again. I am planning on using for RAGBRAI 2025. Thank you Dave Turner!!
Celebrating my one-year anniversary with this amazing bike. Dave was super helpful in ensuring the bike was set up correctly for me. I am 6’2” and he determined the LARGE was the appropriate size. He was spot on. I feel very comfortable on this bike and have completed a season of both gravel and cyclocross racing and well as some epic gravel riding in Colorado, Utah, Arizona, and New Mexico. The Cyclosys performed flawlessly!
Dave - Thanks so much for all your support!
Dave is spot on with the geometry of this bike. I wasn’t sure if I should get a medium or a large but after telling him my height and road bike size, Dave recommended a large. I guessed that a shorter (80mm) stem would be good and it was! First ride was on the farm roads in southern Illinois and I could not be more stoked. The comfort of titanium and 45c tires made short work those loose gravel roads. If you are a “gravel curious” mountain biker, look no further. This is the one!
