Aging tubulars falls in the same category as belief in tread patterns (directional no less) for road tires. I don't believe all the supporters of that subject are joking either. Regardless of the tread pattern, I always mount my tubulars with the decals on the drive side. That's interesting because I put the label of clinchers on the left side of rear wheels so that when changing tubes for a flat, I can see where on the tire the perforation occurred. I mount rear tires from the left side to avoid involvement with grimy sprockets. What is the reason for your choice? I am sure Greg can answer for himself but one possible reason occurs to me; bicycles are always admired, photographed, etc. from the drive side. Maybe he is proud of his tire choice and wants to show it off. This is of course, irrelevant for anyone only interested in technical matters and hard riding but it is harmless. Personally, I don't pay any attention to the label when I mount tires (I use tubulars) and some of my wheels have the labels on one side and some on the other. Yuji Sakuma |

I mount rear tires from the left side to avoid involvement with grimy sprockets. Strange. I might be daft but I must ask, how is the direction of tire mounting affected by the sprockets? Regardless of which side from which I've mounted tires, the sprockets have never been involved. If your tires and tubes naturally levitate away from the rear wheel, then they won't touch the sprockets and holding the wheel by that side will never allow contact with the gear cluster. However, with most bicycles, dropping the tire or tube across the side of the wheel is a possibility that occurs. The same goes for wheeling your bicycle while walking, if you have the bicycle to your right, chances are you can get some chain goo on your leg. What is the reason for your choice? |

Regardless of which side from which I've mounted tires, the sprockets have never been involved. I think what Jobst means is that he lays his bike down on the drive side. I don't do this because it tends to chew up the derailleur mounting bolt, etc. I always mount the tire label at the valve. It doesn't matter if the label is on the left or the right hand side of the tire if its mounted at the valve. after changing tubes you can always locate a sidewall or tread cut if you take this precaution. - Don Gillies San Diego, CA |

When I have my bike to the right, I have a bicycle frame between me and the chainset, which does wonders in preventing chain goo from getting on my legs. -- Steven L.

Bike shops probably have to do both, just for lawyers, but I don't want to have to use a screwdriver just to get a tire off the rim. Some porus base tapes don't need a dry layer of glue applied to them beforehand. The Deda Olimpico (my favorite racing tire) is one of those. Just put a light layer on the rim, let it set for 20 to 40 minutes, and mount the tire. -- Roger Marquis http://www.roble.net/marquis/ Insanity!! Really tho, one light layer onto the rim and none on the tire=tire roll. |

In ~32 years of riding tubulars daily (having switched to and from clinchers 3 times) I've yet to pre-glue a base tape. Only once in that time have I had a problem with adhesion and that was with a Clement Criterium Cotton which had a thick layer of slick latex over its base tape. The only reason pre-glueing base tape may be prudent, and then only with certain porus/unsealed base tapes, is so the solvent fumes from drying rim glue doesn't compromise the tire-to-base tape adhesion. It has nothing to do with tire-to-rim adhesion. If you are paranoid, and do pre-glue base tapes, be sure to use a _very_ thin layer. Too much glue is worse than too little. It's like solder in that you only need enough to fill the gap. -- Roger Marquis http://www.roble.net/marquis/ |

OK, so your an old fart and still don't know what kind of base tape you are looking at. The only reason pre-glueing base tape may be prudent, and then only with certain porus/unsealed base tapes, is so the solvent fumes from drying rim glue doesn't compromise the tire-to-base tape adhesion. It has nothing to do with tire-to-rim adhesion. aka "porous" "porus/unsealed base tapes" are ones on which hard glue or shellac can be used. These adhesives do not hold on coated base tapes but then few people use "Tipo Pista" hard glue. Just the same, tire manufacturers give the user the option by offering bare cloth base tapes. If you are paranoid, and do pre-glue base tapes, be sure to use a _very_ thin layer. Too much glue is worse than too little. It's like solder in that you only need enough to fill the gap. "Very" is a useless word in this and most contexts because it is ill defined and dilutes the adverb/adjective it modifies. Get with quantifiable dimensions. http://www.sheldonbrown.com/brandt/m...-tubulars.html |
