Tubular Tyre Recommendations??
I am in the market for a couple of tubular tyres to put on my spare set of
track wheels........my intention being to use them as a training set, probably on both outdoor and indoor velodromes. When I got them they did have a set of tyres on them but they are pretty old and the rubber has gone hard and brittle and so tonight I ripped them off (consequently I now have sore thumbs). I am sure I can find out on the web but can someone in the know (GemmaK, Bleve, etc) tell me, do I have to remove all of the glue residue from the old tyres before putting new ones on and, if so, what should I use to get it off?? I can remember GemmaK telling me that the actual gluing on takes a while as you have to put the tyres onto the rim first to pre stretch them, prior to actually gluing them on. My thumbs are pretty strong so hopefully I will be able to manage OK. I noticed tonight that the tyres had a cloth rim tape glued to them.......is this a part of the tyre or does it have to be glued on to the rim prior to the tyre being glued on? Also, anyone got any recommendations for what tyres and glue to buy and where to get them at a good price. GemmaK did provide this info to me at one stage but it is on my old computer that died and so I no longer have the emails or the link. Gags |

I don't know, I'm sorry. I always ride clinchers. We haven't seen you at a BBN track race yet, what's up? |

Gags hmmm...this is a personal thing, but its your neck and you need to have confidence in your gear and how its put together... Can only speak for what I use and what goes into the gear I see. My training tyres are Vittoria C-ompetiton- Atlanta's...got them second hand $100 a pair, new, unused... I ride them around Carnegie and sometimes on the road, also have some old Clements I use on the trackie in Fixie mode on the road... On the Boards, Have a Mix of Vittoria -Pista- EvoCS and Challenge -Pista- Handmades...all glued with Vittoria "Mastik" You could use repaired singles too, Walkers sell them sometimes for around $20 each... I wouldnt use them or any repaired single for that matter, but it's your call and if they suit your plans ... As for removing and gluing...it is an art...some die hards use Shellac and it was once the case that "only" Shellac could be used on some tracks back when glues werent so good. ( There are a few who still swear by Shellac...you just have to find them, then find them in a good mood and with lots of time)... if you can't...then use a good glue. I use Vittoria "Mastik" Professional, not cheap, works out close to $4-$5 a tube and that does one tyre... get it at your LBS. The tape (note: its part of the tyre, not a rim tape) ...well the tape on the tyre is necessary, ...( well not always, but gives a level of comfort if your rims has spoke holes which are sharpish), but on re-glues it can cause the tyre to be a bit lumpy and might be removed to get a smoother roll if glue has built up..(I've done this on one of mine and its ok (6 months so far) cleaning dirt and glue off the rims isnt that easy, especially if you come acrosss lousy glue or as some Tubs Ive seen (have been glued on with) " BondCrete "...sheesh... Removing dirt and glue from the rims needs some care, use an emery board for final finishing to get the rim smooth and not damaged...some wheel mechanics use petrol to clean the rims of glue...but dont use a file !!. When gluing you must not get glue into the spoke eyelets, ...pre-stretch the tyre on the rim, start at the top of the rim and stretch down both sides evenly as you work towards the bottom, then flip and pop...its on...needs strong thumbs...inflate to about 7 atm 105psi and leave overnight at least...then remove the tyre and apply even thin coat of glue to the rim and let dry (24hrs)(dont put tyre on yet) .

Others may have a variation on this... if in doubt ...find an LBS that does track work and seek their advice. (Hampton Cycles, Ivanhoe, Kennedy etc)... most critical thing is to ensure even glue, lumps can cause uneven glue thickness and the tube may "move" on the rim and "blow"...not pretty. good luck and grit your teeth and go for it!! -- rooman |

I've read that you shouldn't inflate a tubular if it's not on the rim because it can distort the shape of the tyre. In my experience you put put the tubular on with bare feet, pushing on the bottom of the rim with your toes and feet whilst pulling the tubular over the top of the rim. You need strong hands and good strength. Glue ends up everywhere but is easily cleaned off. Unless you're cycling at a high level I wouldn't bother with tubulars, modern tyres are quite good.

GemmaK did provide this info to me at one stage but it is on my old computer that died and so I no longer have the emails or the link. Gags Have a read of those. http://www.sheldonbrown.com/brandt/m...-tubulars.html http://www.parktool.com/repair/readhowto.asp?id=101 The glue can be removed with acetone or even mineral turps ( make sure you remove all residue ) I just got some nice Vittoria Pista CL tubulars off http://www.probikekit.com , got them for under $80, they sell for around $160 in most shops, these are only suitable for indoor timber type tracks using them on a cement or tar track would destroy them very quickly. I also got some cheap ( $21 ) foxonall tubulars at the same time to use as spares for road, and for some of the club road racing, I have glued one onto a wheel and it seems to be reasonably straight, not as good as a cheap clincher but it should yield a smooth ride despite the wobble of the less than perfect made tyre. I am using some Schwalbe Stelvio tubulars that I got locally for $50 each for club racing and opens on cement or tar, they are a cheapo road tyre and seem to perform ok, one was reasonably straight but the one that I put on the rear has quite a wobble, it is not affecting ride as it is only the two tone compound that wobbles side to side a bit, no amount of twisting and resetting it would remove it. For training your really best to ditch the tubulars and get a set of clinchers as they are much less hassle in the long run and to be honest cheap clinchers are better than cheap tubulars, as the cheap tubulars do not run very straight and tend to be lumpy. I have clinchers that I use as training and for general club racing on cement or tar tracks. And some tips I got recently from my friend who has raced in many world championship track races As for removing tubulars off a rim lever a screw driver under it and roll it around under the tyre to remove it easily without destroying the base tape. And his recommended glue for track is Continental, I told him I had just bought a tin of Vittoria and he said don't bother with it for track go and get some Continental glue, he also suggested that I get rid of all my tubular wheels and get clinchers. And he also suggested that I make sure I always use tyre covers on my Pista CL tubulars as just transporting them in a car can make the side walls fail due to them rubbing against each other, and not to warm up on them only race, and when fitting them to the rims do not drag the side walls over the sides of the rims as they can pick up and damage the sidewalls. |

Friday No need to get any glue on anything other than where it's meant to be...if you make a mess you are doing it wrong... the glue has to first dry (24hrs)on the rim, then a thin ...empahasis _thin_, coat on rim and tyre, let dry about an hour, it will be touch dry. Friday...I think you should leave well enough alone! better still go see Greg Griffiths at Ivanhoe Cycles, he knows tubulars, shellac, glue and combinations for the best outcome.... if you want to ride safely, do it right... (IMO)I am loathe to race against anyone using High Pressures on the track...why...generally most HP users overinflate, they have a flat and the tube comes off the rim at speed...bad news for everyone...Tubulars are glued to the rim, you can run it morer safely flat and slow down keeping some control...goes for the road and the track... tubulars just need some service support but they roll better, and are overall safer (IMO). Sure they are a good option to get people going and new riders started up at a lower cost...soon when the bug bites, youll want to be refining your technique and gear, and when its down to tenths and hundreds of seconds then these choices matter. -- rooman |

Do a search through their forums for some excellent discussion on tyre choice, and gluing the buggers onto your rims. Here is a link to the faq on the site: http://www.fixedgearfever.com/modules.php?name=FAQ There is also a good piece of research done on glue types (referenced somewhere on fgf). Mastik come out tops, closely followed by continental. My (vittoria) tubs are glued on with conty glue, and I have had no issue. I get my tubs from probikekit for obvious reasons. -- warrwych |

You need strong hands and good strength. Glue ends up everywhere but is easily cleaned off. If you have got glue everywhere you're doing it wrong....! Good Tyre choices (from my experience) for indoor/outdoor tracks: Continental Tempo http://www.probikekit.com/display.php?code=Y1256 or Continental Competition (if your outdoor track gets glass on it): http://www.probikekit.com/display.php?code=Y1111 Tufo S3 Pro http://www.bikemania.biz/Tufo_S3_PRO...ro_t_tires.htm For indoor$ only: Tufo S3Lite Continental Sondeclasse Vittoria Pista http://www.probikekit.com/display.php?code=Y1210 The Tufo's are the roundest tyres of them all... All the indoor-only tyres have very fragile sidewalls, and extremely poor puncture resistance (ie you'll get a puncture wheeling your bike in the carpark or frmo riding over a bit of gravel on the track). The Vittoria Pista also has a very thin latex innertube which means it goes flat pretty quickly (ie have to pump up lunchtime again at an all-day meet). I either use Vittoria Mastic 1 (the red one), or Continental glue. For tyres that are reglued often I prefer continental glue, it doens't build up too thick. I had the pleasure of watching one of the agritubel mechanics gluing on singles last week and he used exactly the same method as me! Which is: Prestretch tyres (preferably on spare rim, or else stretch using your feet and hands) Clean rim with acetone, if it has glue on it already that's OK as long as it's not chunky/lumpy. I like a layer of glue on there already, it reacts with new glue anyway. If you clean it properly with acetone there's no need to do any sanding on new rims. I only sand lumps of old glue off. Pump up tyre until it just starts turning inside out. Use paintbrush (or continental glue applicator) to paint a thin layer on both the rim and tyre. Go right to the edges on both. It is the edges that give the bond its strength. Try not to gloop too much down the spoke holes and valve hole (some wheelbuilders plug spokeholes with cork). Let dry. If tyre has a very absorbant rim tape (ie continental or Tufo) put on another thin layer on the base tape. When all is dry, put on another thin layer on the rim. Wait until it's quite dry and not too tacky. This can be as little as 5mins for continental glue on a warm day or over an hour for the gluggier Vittoria Mastic. If it looks like it will be messy, it's not dry enough! The pro mechanic waited about 10 minutes with Conti Glue :-) Make sure the floor is clean. Clean tiles are good. Place the wheel valve side up on the floor. Deflate tyre and take your shoes off. Poke valve thru valve hole - straight! & Using all your strength grip the tyre about 20cm each side of the valve, tension the tyre as much as possible and stretch the tyre equally on to the rim. The glue is a contact adhesive and will stick as it lands on the rim. Keep doing a few times as you work the tyre on you're at 20-to-4o'clock. Turn wheel over and use your big toes to hold wheel down as you pinch/pull the last bit of tyre and lift it onto the rim**. It's a sort of pinching, rolling movement. If you have been stretching it on early it's pretty easy. (**if you are working with a deep dish wheel or disk, put the valve end of the wheel against your middle and grip the wheel with your guts by bending over as you work the last bit of tyre on (not a good look but it works) Pump up tyre enough so it has it's reasonable shape (about 50psi) Spin wheel and check it's in the middle. Work the wobbles out quickly by breaking the glue contact by rolling tyre back and forth in that section and get the tyre back to the middle. Pump up tyre to max. Weight the tyre (either put it in the bike, get on and roll tyre back and forth, or else just lean on it with all your weight section by section) to get the maximum glue contact. Leave for at least 8hrs (Conti glue) or 24hrs for Mastic. Done. Use acetone to clean the floor if you left a stripe of glue behind. Enjoy the glue fumes. I learnt a trick from the mechanic - to get the tyres off again he didn't ruin his thumbs... he simply worked a thin screwdriver under the tyre and poked it out the other side. Then he grabbed onto both ends of the screwdriver and just forced it around the rim - voi-la! I will try that next time. Here is the blistery result of me peeling one of my well-glued track tyres off: http://img11.picsplace.to/img.php?fi...2/IMG_1172.JPG http://img4.picsplace.to/img.php?fil...9/IMG_1173.JPG Gemm |
