Hello I'm new to the forums. I've been reading around for the past few weeks and finally decided a cyclocross will be right for me. i'm currently stationed in Italy and I'm having difficulty figuring out how I am going to get into this. If I had a LBS that spoke English and had some cyclocross bikes, I probably would not need to post this. I decided I would not purchase a bike anywhere here as the dollar is very weak so I have to resort to buying online. However, there are no dedicated Cyclocross bikes at the bike shop i have been to here that could give me an idea of fit and sizing. I'm 5'10 with a hair over a 33" inseam and I had been riding 56cm road bikes back in the states. However I had 80s Bianchis and Fujis that I can not get a look-up on the geometry to give me a comparison to the bikes I'm currently looking at online. I am also restricted to buying from sites that ship to an APO address(military P.O. box) so that limits some of my options. I plan on riding 50% road 50% gravel/light singletrack.
I was looking at this Diamondback Steilacoom and the DB Haanjo Comp bikes. With my inseam, the Comp's 56cm standover would more likely fit me i believe while the RCX would be pushing it. However from my readings, I've been told I should focus more on TT length. I have no idea what my ideal TT length would be. As i said earlier though, I have nothing to compare it to currently. I have always bought and rode what fits. However I'd imagine that a 56cm is much more likely to fit me than the 53cm bike. Anyhow, buying without riding seems very sketchy to me however I don't have much other options. I don't mean to come in here and not try and help myself. I've been reading threads on fitting a bike and all the technicalities leave my head spinning. I'm just looking for some practical advice..Possibly someone with similar geometry to me can give me some advice. Or maybe I should be looking at some other bikes? I'm really not sure where to begin.
Looking at that chart, and looking up some of those bike's geometry's has popped a question in my head. Some people were quoting their inseams, then i go to check the standover height and was often taller than their inseam by .5-2 inches! I don't see how that would be very feasible when doing any recreational trail riding.
Anyhow, comparing the specs to many of those bikes listed for those around my height and inseam and the ideal TT length, I think the 56cm TT length would be okay for the RCX and I am seriously considering buying it in the next few days.
I have an Italian made Pinarello frame set, its a 57-57, Im 5'9".. wear about the same pants inseam.
it's a touring, not a CX race fit.
Hey no offense, but I've been browsing this site for a minute and I've noticed you have a pretty high post count but you don't really provide any useful advice to most users asking questions. I just thought I'd throw that out there.
Honestly, I'm thinking of biting the bullet and maybe just paying the extra 300$ or so it would cost to buy a bike here at a LBS because I'm feeling really ancy about buying a bike without riding/fitting it first......
