the roubaix will be tougher than carbons, they'll still puncture, but some risk avoidance will help
Just for information, all Veloflex tyres (including their open tubulars) share the exact same callicot protection.
It may however be wider as the tyre grows wider compared to the Carbon model but that's about it.
IMHO the best way to protect yourself from puncturing tyre like these is to age them properly for about six months.
While that doesn't mean you could ride through all kinds of debris it does mean that instead of puncturing for no obvious reason with a factory fresh tyre, say every other 500km or so, you'd now ride them basically untill their end of life without a single puncture.
Such is my experience and that's the feedback I recieve from other riders as well. Aging make a world of difference.
Mileage will vary from rider to rider and I won't want to make statistics on this. Still, that being said, the upper end Conti tyres are better equiped against urban debris with their Vectran anti-puncture layer but it does come at a premium.
Not the Vectran layer's fault, just this stupidly harsh casing they use.
for glue removal, white spirit is easy to get and safe - as long as you don't ignite it
To be honest I'm not so sure it's all that safe. Most mineral spirits like these aren't but I haven't looked this one up yet on MSDS.
@ Ohpinchy: I wouldn't get too particular on what brush to use. A cheap acid brush about the same width of the rim will do just fine. Forget about syringes and finger in bag techniques. Too many nutters on YouTube if you'd ask me.
I'd also advise to buy Mastik One in tubes, not cans unless you're planning on serving an entire team or have an incredible amount of wheels to glue up somehow.....
Cans don't last too long, maybe three years at most once they've been opened. Solvents flash off whilst the can is open and since it's a cement you'll never close that can and have it airtight again as there always be that inevitable layer of cement on the cans' rim and its lid which allow the solvents to further flash off as it's sitting idle.
