Recently picked up a set of FFWD F6r tubs and bought some Vittoria Corsa G 2.0 25mm tubs.
Plan is to tape them on using the Effetto Mariposa tape.

Planning on using them for crit racing (on an oval track) and can't wait to give them a spin.
Im curious why u will use tape vs glue with Mastik for example?
Honestly, because I feel that glue will be too much faff.
I've got a couple of friends that have been flying tubs for years and they didn't sell it to me, and tbf they told me to just tape them.

My LBS glues tubs for £45 a wheel though

I feel u totally now.. But i'll share my experience which was similar as yours.. And some tried to explaing me like glueing is not that mess/hard as it look like and better than tape.. And if u go with tubular go all the way.. Also glueing is part of ritual :)

First few tries i done back then was dissaster.. But i made few mistakes, one of them was too much pressure in the tire.. I even wanted to get back to clinchers and almost sold my tubular wheelsets..

But when u start feeling what to do is really easy, and not time consuming as it look like

So i suggest to try it.. And ur self.. U dont need LBS for that.

If u have new wheelsets:

1. Use some scotch brite to sand the wheelsets (just slightly to make ti better for glue connection)

2. One thin layer on rim, One thin layer on tire

Wait 24h

3. Another thin layer on rim, Another thin layer on tire

Wait 24h

4. This is most important step: Final step

Before putting glue now try to put tire on rim and find which pressure is best to be able to put, but still some pressure in tire.. Consider with glue will be a bit harder so maybe remove just a tid air pressure..

Put final layer of glue on rim and install the tire

5. Pump it about 2 bar.. Center the tire and after this im using pole stick to press the tire in the rim

Center again if needed

6. Im using my weight to press tire inside the rim on as many spots as possible on 360 deg

Then pump it to about 7-8 bars.. Wait 24h

7. Remove pressure from tire and use thumb test (with some pressure try to remove the tire from the rim)

If u allready have glue on wheels and just putting new tire, then just one thin layer to smooth everything and next is final layer (after 24h)


Again try it.. All this steps took very little time per step, and if have some skills in hands it's not hard at all.. And almost forget, stretch new tires on some spare wheelsets/rims for few days or better weeks (depend from tire. If u use Cotton based tires u dont need too much force to install it. If u use Conti tubs as long as possible will help).

I tried your method when I was a tub newbie. Now I combine water mehod and 1-layer method with great result. Minimum glue and time spent, proven safe even during fast technical descending.

@3Pio Exactly my thoughts.... tubulars, rim brakes, mechanical shifting. :thumbup: :D

Anyone else convinced tubulars still roll faster than the current cream of the crop tubeless clinchers?
They are still so much more comfortable than high thread supple casing tubeless.
I'm getting more and more leery of rolling resistance tests. Makes sense for WT/Pros to move away from them for ease of maintenance though.

^. nope tubeless is faster and larger volume makes then even feel better. That being said I will always probably have 1 or 2 wheelsets that are tubs.

This is 2-3 years old and this part of the tread is slowly peeling off. How should I fix it?

Actually an easy fix. I would recommend:

1. Cleaning both surfaces (the underside of the tread and the casing) as well as practicable with a Q-tip (or similar) dipped in alcohol;
2. Applying Barge cement to both surfaces (you will need a toothpick, or something, to get the cement in as deeply as you can);
3. Let the surfaces cure-up overnight;
4. Inflate fully (6-6.5 BARish);
5. Firmly secure the repaired area with a strap (I use an old toestrap, wrapped around a few times) with a piece of cardboard to get the repaired area as flat as practicable, maintaining the curvature of the tire sidewall.

It should be ready-to ride the next day.

Thanks for the tips. I don't have barge cement. Would Mastic One work?

@jlok, no, I remember trying that when I was a Cadet. It does not work.

What you need is a high-strength, permanent contact cement. There are a number of applications that will have adhesives that could work for that application. The first place I would recommend you looking is the shoe repair industry. One good source would be your local sport climbing supply store. The adhesive that rock climbers use to re-sole rock shoes will likely work well (that is actually one of the applications of Barge Cement).

Hi all! I am new to this site, so my apologies if I am posting in the wrong place! I have a set of Fast Forward f6r full carbon tubular wheels that are in mint condition (I brought them into Trek Bike and learned that they have actually stopped making the type of set that I have and that the value is rapidly increasing) I am looking to sell but since this is not my forte, I was hoping to get some help with some questions about them!

1. I believe the wheels themselves have not ever been used.... From what i understand, tires need to be glued on, correct? And I assume this process would be easily noticeable if tires had been once glued on and removed?(I believe that the only thing that has been previously used on them is the hub driver)

2. Other than pinkbike, is there any other places that anyone would recommend for my to list these for sale?

TIA!!!

If the value is rapidly increasing I'm sure a member here will pm you soon offering top dollar.
