  • these tubs simply excell so why not use them,

    I puncture MTB tyres a fair bit. But as I'm sending Stan's kids to college I just keep riding :)

    I've never seen anyone on MTB tubulars in the wild. I remember seeing them at the designed to win exhibit and being blown away. These were 26" mind.

    I bet they ride so well.

  • Hub is shimano and I need campy 11.

  • 10 speed Shimano? If it's 11 just run a Shimano cassette.

  • Are your zipp wheels shimano 11 speed compatinle if so run a shimano 11 speed cassette or if you dont like the ratio's on offer use a miche shimano 11 speed compatible cassette. Zipp do make 11 speed freehubs for campagnolo. You might be choosing the most expensive path unless you just want ride of the zipp hubs in which case fair enough.

  • Yes they do ride well. I am the only person i know who uses them.

  • Would a lightly used pair of Hutchinson ORO Servizio Corse tubs & a pair of Mavic Reflex 32 hole rims be of use to anyone?

  • and I've got a half-full tin of Mastik One, for free, if anyone's in need. Collection N16.

  • Anybody have any advice specific to glueing CX tubs on to carbon rims?

    Need to do a fairly pricey set and despite having glued road and track tubs in the past I'm a little nervous.

  • If your tub rims are modern and wide, then build up a good glue coat on them, hit the tub with some glue, mount and you should be OK, even at low pressures.

    If they are narrow, then I've used a mix of tape and glue - but if you go down this route the removal process is pretty much destructive.

  • Alternatively I've heard mostly good things about Effetto Mariposa tape. A bit easier than glue and alot easier than glue and tape. Though have witnessed one rider using it rolling a tub this season.

  • Layers of glue is best. I'd do a minimum of 4, and leave 24 hours between the 3rd and 4th layers.

    For security, tape and glue is great but, as you say, you'll never get the tub off without damaging it to the point where it's only good for the bin.

  • Thanks people, much the same as glueing any other tubs then.

  • One thing I found helpful was to inflate the tub and offer it up/compare the profile of the base to that of the rim. This should give you an idea of where on the room might need more glue to ensure a good bond.

  • That's helpful, I never really considered trying that but it makes sense.

  • Layers is what I meant, yea :)

    Did my major toms the way you describe.

  • looking for advice - is there a way to define which tubs size is dedicated to rim width? sth like with sheldon clinchers rim width table.

    i have rims with external width at about 18mm but with rather deep internal profile. i wonder if 24mm tubulars will fit them and won't slip of in turns and corners.

    anyone?

  • Good value 25mm tubs? Gatorskins are rated right? And better/grippier than their clincher counterparts?

  • 23-25 is my range of choice. but it's a rim profile that matters. if 23-25mm tub will stick to the rim without any gaps.

    edt
    if there's some table of compatibility maybe? or at least some rules about that.

  • Gators are durable. They don't feel very tub like though. Schwalbe One might be worth a punt too. Neither have latex tubes IIRC

  • I've never had any problems with Vittoria Rally tubs and they are very affordable. Halfords used to sell them for about £13 each and Ebay has them for around £16 each.
    They are not the greatest for feeling like tubs but they are pretty durable for commuting.
    I suppose it depends on what you want to use them for and how deep you're pockets are.

  • Okay decided I'm going to splash out on something nice as I'm spunking enough on the wheels. So probably some Vittoria Evo CX or the new graphene variant.

    Do tubulars tend to differ in profile to same degree as clinchers? Or does 25mm tend to be a true 25mm?

    Asking as I'm fairly tight for clearance. Rims are 24.3mm on the wheels I've bought so assuming that means I can't run a 23mm tub?

    Anybody know how the Vittorias measure up specifically?

  • Or does 25mm tend to be a true 25mm?

    Tubulars tend, on the whole, to be pretty true to width. Depending upon construction their height, however, can differ a bit. Recall the shape of the tyre, in contrast to clinchers, is immutable to rim design. Tubular tyres are round. Given variation in roundness, etc. I'd avoid overly tight fits. Most frames, however, will accommodate 25mm tubulars. Some bicycles might have problems fitting Clement Campionato del Mondo (28mm) but they've been out of production for more than 30 years..

  • Tubs tend to follow clinchers in my experience. Veloflex and Vittoria tend to come up smaller than Continental.

    Re your tub choice, what do you want them for ? If mostly city riding and/or wet weather riding I'd stick with Conti as they tend to be more durable and grippier. Regular Sprinters are durable enough, no need for Gatorskins. Competitions if you're feeling a bit more spendy.

    If you want something more traditionally tub like with a latex tube, then Veloflex. They're more fragile than Conti's, but seem to have better grip and durability compared to Vittoria.

    I tried city riding on Vittoria Corsa EVO CX IIIs once and found they lasted about a month, normally cut to death by glass.

  • Thanks both.

    Gone for the Vittoria Corsa Graphene. They're for racing so decided it makes sense to spend a bit but tubs are fucking pricey aren't they? I wanted latex tubes over butyl for faster rolling.

    Bought a Vittoria Rally as a spare I can keep pre-glued.

    Need to learn how to glue them now as the up-thread wisdom says that's the best bet.

  • Just got a Corsa G+ Isotech aka pretty much the fastest current tub. Will have to sharpie the sidewalls, who thought grey was a good idea?
