Comparing a tire’s effect on ride quality is admittedly subjective. But one thing I compare (beyond how I think it feels) is this: while riding I keep an eye on my front tire’s leading edge. I watch how much vibration it exhibits. Clinchers vs tubular or even a hard tire vs a supple tire all show different degrees of bounce or chatter which is easily seen. This is not entirely objective but it is at least observable. My supple Corsa G+’s barely move. Other tires chatter. It would be interesting to see if others notice any correlation of tire quality to ride quality this way. Other factors in play here: the wheel build (rim type, spoke number/gauge/butted or not, etc.) and tire size/inflation are probably the biggest two. My wheel builds are all 36 spoke 3 cross and butted spokes (15/16/15 or 1.8/1.6/1.8). For all my tubulars I ride the rear at the lowest psi recommendation and the front 5-10 psi lower. Today on 25mm tires that meant a bit over 100 rear and a bit over 90 front. By the way, I'm also riding a Vittoria G+ in front, and another Vittoria G+ in back. (That's roundabout phrasing, but I couldn't come up with a rational-looking way of making a plural out of "Vittoria G+.") They seem like nice tires, although I have nothing to compare them to. |
A question for the group. I bought a pair of tubular rims a year or so ago, and a set of Record hubs is awaiting me in Ohio.
A couple months ago I suffered an injury to my left index finger and, just this week learned it will never again be fully functional. As in the flexor tendon waited too long to be repaired. Doctor error. Can I consider mounting tubulars in this condition? It wouldn't be the end of the world. TIA |
seedsbelize I just went out to the garage and tried mounting a tubular to a rim without using my index finger. It was more difficult but not insurmountable. My method is to insert the valve into its hole, then with the wheel vertical, valve and hole at the top, I grip the tire on either side of the valve with my two hands and stretch it onto the rim working from top to bottom. Gripping and stretching without use of the index finger was awkward for me. The tire I used has been previously mounted to a rim, so not as difficult as some brand new tires. My suspicion is that, just performing your normal daily tasks, you will learn to compensate with your other fingers but I'm no occupational therapist.

Old tubulars - possible to re-glue base tape ?
Hi, does anyone have experience of repairing loose base tape on old tubulars ?
I picked up a 1970s Motobecane 10-speed at a junk yard and want to clean it up for occasional short trips around where I live. The old tubulars were flat of course after years of being abandoned somewhere, but I pumped them up to 100 psi and they held pressure without an issue. When I took them off the rims they came right off because the glue was long gone, but some of the base tape is not so well connected to the tyre. I want to keep the bike as original as possible and not spend much money on it, so if I could avoid buying 2 new tubulars I’d like to try to fix them up. |
seedsbelize I would avoid Continental tubulars. The Competitions are a real bear and the Sprinter Gatorskins are almost as bad. The Vittoria Corsa and Rally are much easier. You could have the LBS or a neighbor put them on your stretching rims and then do your gluing a couple weeks later.

Seeet! Does it measure a true 25mm or a little wide? Actually I was looking at 28mm because that's a hard max for the Merckx.

If you spring for that, you may as well spend another $20 to get the tubes replaced. Personally, I would buy new tires. |
We all know tires make the ride. It was proven to me once again over the last few days. I acquired a 78 Team Champion and just so I could ride it, I threw some Pelissier 2000/GP4s on it mounting Challenge Strada tires. Bike felt sluggish. Rode it twice just to be sure it wasn't just an off day for me. Still a slug. Switched to Pelissier 2000/OR10 with FMB 25mm Paris-Roubaix. Well, I was having an off day, but the bike was alive and I rode further than I would have otherwise. Granted the rims are lighter on the latter, but this is not the first time I have put good tubulars on a slug and it came alive.
My conclusion. Spend the money of good tires. You only live once. I have found Veloflex and FMB to be a cut above most others and less prone to flatting. YMMV https://cimg2.ibsrv.net/gimg/bikefor...4a0dcc5109.jpg |

Thx for the tip, don’t know what I was thinking trying to fix up 30 year old rubber anyway🙈 Trev |

Also, keep your eyes and ears open to what tires (and to a lesser extent rims) mount easiest, This isn't like clinchers where too easy and you risk blow-offs. Once the glue is set, tightness doesn't matter.

Thanks for all the tips, whether directed at me or not. I would prefer to find tires in Mexico, even at half again the price. I am so far unable to find Vlaanderens. I have an inquiry in to an Ebay seller as to shipping here. Is Ebay a safe place to shop these days?
|
Best I can tell from Veloflex site, Vlaanderens are no longer in production. 🙁

I believe you are correct. Which explains some of the really good prices in the last few months. Check around and you may find some. Lordgun.com had some as I am writing this.

I'm one of those guys who read instructions.....but Vittoria has confused me. on my new can of mastik it says put a coat on the rim and on the tire tape and then wait a day, putting another coat on the rim only, wait 3 to 5 minutes and mount the tire. the instructions that came with my vittoria tires say put glue on the tire and wait 30 to 60 minutes Then put glue on the rim and mount the tire. fairly different only consistent instruction is to wait 24hours before riding
thoughts and/or what have you done? |

thoughts and/or what have you done? It's not just Vittoria I don't think. Everybody has their own special method of gluing tires. I expect the rest times matter less than the instructions would imply. Just make sure the glue gets plenty of time to harden after mounting and inflating the tires. |
