Backpack or pannier

Agreed. But what is the point of buying a road bike with a short wheel base and trying to turn it into a touring bike? Don't get it. If you want a bike to use as both, there are plenty of options.

A lot of people try to re-purpose an old road bike into a commute bike or errand bike because they prefer the road bike wheels, bars, etc.. Unless you're carrying heavy loads for long distances it's fine to hang some panniers on a rack. A rack with a long enough platform to ensure sufficient heel clearance is essential, especially for those with larger feet. We're only talking a few inches difference between a rack that works and a rack that doesn't. It doesn't cost much for the manufacturer to include the mounts for racks and fenders. I haven't bought a new road bike recently, but in searching for one for my son I was pleased that as I narrowed the choice down based on size, frame geometry, material, price, braze-ons/mounts, rims, gearing, shifter types, etc., the two acceptable models both could have racks if ever needed. |

Yes like I said you can find a bike to use for both. Roubaix works for a road bike and panniers fit fine. -- duane |

Front low rider bags can make a racig geometry bike very twitchy especially in strong cross winds or gusts. Also, most racing bikes don't have a way to mount low rider racks unleds you use U-clamps and P-clamps. I don't think I'd want either on a racing fork. Also, using a front rack means you have to use two bags and have nearly equal weight in both so as not to have to constantly hold the bike on course. And you can probably forget about any no hands riding if you're on a quiet stretch of road where you might be tempted to ride no hands for a spell. Cheers |

Lots of bike of all stripes. Even saw a couple bents today. Sometimes it doesn't take much rearward movement to upset the handling of a bicycle.

Diffeent horses designed for different courses and/or uses Well if you don't mind a back pack you can certainly commute on a road bike without racks or fenders. Same horse different course g Cheers -- duane |

Kludging a front rack was far more difficult and would have required clamps. Yes, clamps are likely necessary. They were when I adapted my daughter's road bike for our coast-to-coast tour. I also fitted a rear rack, handlebar bag, wider tires and fenders. All of that required considerable work, but once that was done, it worked well for her. - Frank Krygowski |

I've never used them on a racing-geometry bike, but I've certainly never had any problems with twitchiness or crosswinds on "sport touring" or full-touring frames. I don't see a reason that adding mass to the fork would cause the bike to be more twitchy. The polar moment of inertia about the steering axis must obviously increase, so any angular acceleration of the forks & handlebars would tend to be reduced, not increased. What mechanism would counter that tendency? Also, using a front rack means you have to use two bags and have nearly equal weight in both so as not to have to constantly hold the bike on course.. And you can probably forget about any no hands riding if you're on a quiet stretch of road where you might be tempted to ride no hands for a spell. I think the equal weight thing is overblown. I've done thousands of miles touring, paying no particular attention to balancing my loads left to right.. I've done thousands of miles of utility riding with similar disinterest in balancing loads, including riding with only one rear pannier. Your bike may lean a degree left or right, but it's no big deal, in my experience. Bikes and riders are pretty adaptable. If your experience differs, I'd be interested in details. - Frank Krygowski |

Snipped - Frank Krygowski Therein lies the difference. Pure racing bikes do handle differently than sport touring or touring bicycles. The lesser amount of fork rake on a pure racing bike can lead to a lot of problems if you hang panniers on a rack on the front. One of your problems might very well be fot striking a pannier in a low speed turn. There's pretty good reasons why someone commuting on a pure racing bike usually uses a backpack for their gear rather than trying to kludge a rack and pannier(s) to fit where they were never designed to fit.

https://www.google.com/#q=BICYCLE+PH...OUNTERSTEERING loading the fork may reduce the bicycle's raison physics from squashing front tire's contact patch down onto the pave into a friction hold mode not the usual rolling mode as main component in the bike's physical attributes. with more and more on fork weight, the bike asks tube ridden more and more upright...not falling into turns. sensation is powering a FWD system with rear wheel as a trailer. Sensation of riding a bicycle is gone. Brandt and I would go around on this with Brandt taking an antagonistic position for loading the front end increasing total braking stability and control. I argued a rear weight bias produced directional control that as more important than total short stop performance. Esp on low friction surfaces where total short distance stop wazingonna happen anyway. If you load left over right then again the contact patch is irregular. Your analysis please.... maybe in high winds ? idea of a fatter front tire than rear for loose surfaces supports the almost universal low front weight opinion. |
