700X vs. Dynamik tire clearance?
Semi-aging all-around rider here (road, commute and mtb on all varieties of terrain), considering going CF for comfort on the terrain where it's doable. I'd still keep a DF 29"er bike for more technical singletrack where CF isn't optimal. I'm wondering if there's a difference in tire clearance between the 700X and the Dynamik? If I got one of these bikes I'd probably run 700x32 (summer) to 700x38 (winter) tires for pavement duty. It sounds like 700x38s might barely fit the 700X -- will they also fit the Dynamik, or are the stay bridges closer in? For dirt/gravel road touring and mild singletrack I'd like to run MTB tires, most likely on 26" rims. I understand that the Dynamik will take 26x2.3" tires. Does the 700X have enough width at the appropriate point to run the same tires? If the answer to both questions is "yes", is the difference in framesets between the two basically color and fork choice? I've got tons of components in the parts bin and would be buying the frameset only. Also by the way, I'd be running disc brakes so brake reach and clearance aren't an issue for me. Thanks in advance for any help on this. - Dan |

I think the 700X and Dynamik use the same frame. The only difference is tire size. Please correct me if I'm wrong. I'm not sure if they have different forks. Dan U |

Re: 700X vs. Dynamik tire clearance?
Thanks, Dan. I'm looking for whichever has the most versatility in terms of clearance, so if these frames are the same in this respect then great. I can ignore that factor and focus on color, fork choice and price in deciding which frameset to get. By the way, it looks like the base Dynamik comes with an aluminum Kinesis fork for $700-ish (frameset), the Dynamik Trail and Dynamik Pro come with a Rock Shox SID suspension fork for about $1050, and the 700X comes with a carbon cyclocross fork for $850. Not sure which I'd get at this point. |

Re: 700X vs. Dynamik tire clearance?
I've just got a s/h Dynamik. I've tried it with 700 x 28 ultra gatorskins, 26" x 2.3 off road tyres, 26" x 2.35 Big Apples. Discs make for easy 700 / 26" change. I found off road rear 2.3" caught chain when in lowest gear and will go for 2.1" with a more rounded profile. All that stuff about being good at climbing by pulling on bars rather than standing on pedals, well it's true :) Maybe not as good in technical singletrack as my 29er DF mtb, but good enough and so much better comfort wise that I'm letting the mtb go. The 700 x 28 are nice on the road too. I've been really impressed with it's comfort, performance and versatility so far. |

Re: 700X vs. Dynamik tire clearance?
Andy, I'm curious as to why the 29er MTB is better in singletrack for you. The Crank Forward platform might take a little practise in the singletrack, after a while (with a few modifications) I got better then on a more vertical seatpost.

Re: 700X vs. Dynamik tire clearance?
Simon, Actually 'better' at the moment really means 'more familiar'. I'm going to get a curved stem as that should give a bit more room out of the saddle. I also said that a couple of rides have been enough for me to know I can let go the 29er :) (And I have) It is harder to go from seated to standing on the CF which affects manouverability in some places, but no doubt practise and improved tummy muscles will help. I've switched to 8 speed, which means I could use a 7 speed cassette with a spacer where the granny cog goes, which will probably work with knobblie 2.3 tyre. So perhaps I won't have to go for 2.1 off road tyre. I'll give that a try. That ability to climb pulling on the bars is great, though second time out going up a big long steep hill I did end up overdoing it and my arms were sore for a few days after :) Very tempting to get another CF frame and an ENO eccentric rear wheel and try a fixed / singlespeed set up. |

Re: 700X vs. Dynamik tire clearance?
Andy, Stand riding does take some time to master, on my Z-Pro I am starting to not think about it and just do it when needed, but I have ridden it 3 years. I am not the best example of quick adaption. But it took understanding that sometimes you only lift a little out of the saddle, and other times a full out stand. Experiment with caution, some find contolling the bike while standing not so easy, a lot of that is how you place your upper torso. |

Re: 700X vs. Dynamik tire clearance?
Andy, which 29er mtb did you go with? I have been considering the SIR9 by www.ninerbikes.com after meeting the designer/owner Sea Otter. Saw this one at the show also: http://spincyclz.com/images/IMG_6483.JPG Regards, ~Nanda |

Re: 700X vs. Dynamik tire clearance?
Nanda, I had an On-One steel 29er. It was great and I'd just got some Reba 29er forks to fit, but like I say a couple of rides on the Dynamik and I sold the 29er and Rebas. |

Re: 700X vs. Dynamik tire clearance?
That's good news then!!! I know 700x35 tires will clear on the Dynamik alloy fork, but a true 29er design would be needed to take advantage of the 29x2.3 tires and the steam-rolling capabilities they offer eh. I am also a Dynaddict, and will be taking my third ride of the week on Tavia tonight. There is a nice paved climb that I like to do, because it's just minutes from home and all the sudden you're into an instant workout for a solid 20+ minutes of climbing. Regards, ~Nanda |
