Hi, I think F-C is an important parameter for Grant's designs. Here's a thread: https://groups.google.com/g/rbw-owners-bunch/c/dW25Rl2Qf3M/m/FL_RhSQwAwAJ
I think Joe's point about the type of handlebar to which he's designing the frame around is important, and has permitted him to expand F-C over the years in other models. Grant designs for where he rides (and how he rides). If your ride conditions are different, it might not work as well for you. Longer chain stays probably help quite a bit on steep hard-pack dirt for climbing and descending. East Bay trails aren't rooted like New England trails, so popping up front wheel or other MTB-maneuvers isn't as important. For me, my low-trail bike washes out on loose dirt trails compared to my Riv. Good luck! shoji Arlington MA On Tuesday, March 16, 2021 at 2:39:33 PM UTC-4 reca...@gmail.com wrote: > Hello All, > > Since I've been *very* slowly getting into DIY framebuilding over the > past few years, and by way of it, trying to better understand why some > geometries work for me and my kind of riding over others, I have come to > appreciate the method of builders like Waltworks in terms of using > front-center as a guide for putting together a frame geometry with relation > to getting the rider's weight distribution the way they want it (i.e. > getting the bike to ride and fit the way one wants). > > A corollary to this is that a builder might then use, like Waltworks the > following method (paraphrased): > > > 1. pick the trail you want > 2. pick where you want your wheels to be > 3. pick BB height > 4. make sure the person can then fit the bike in the desired > position(s) through HT length, stem, bars, etc. > > So my long-winded question is, with Grant's emphasis on getting more > upright and weight to the back while making the chainstays longer to > accommodate this, what might be the corresponding logic of making the > front-center length of the Susie/Wolbis almost so long?
