After a couple more rides with the Arenbergs I was still not getting good feedback from the tyres so I decided to change. I looked at going back to Tufo's with which I had never had grip issues. The S3 23mm which I had been riding were comfortable (the 375 tpi version). I opted for the Elite Pulse 25mm tubs, also 375 tpi, which are actually suggested for triathlon but as far as I can see they are basically a slightly wider version of the S3. I mounted them with Tufo Extreme tape and went riding. What a difference! Straight out on the road they felt just as comfortable as the Arenbergs but grip and feed back was much better - no nerves from me at all. I used similar pressures in both set ups from 90 to 95psi front and around 100psi on the rear.
I terms of speed they feel just as fast as the Arenbergs maybe a tad quicker (the Tufos weighed in at 248g each rather than their listed 280g. The Veloflexs were 282g each. Using the Tufo tap also saved 20g per wheel). Whether it was just the tub or the combination of tub with the Effeto glue tape I can't say but I am very glad I switched to the Tufos. So I have a clean and virtually unmarked pair of Veloflex going on ebay. Others may love 'em but not for me.
Normally one should not respond, but this one is worth the effort. First, the post is comparing apples and oranges. A 25 mm (rides like 26) Veloflex for elite cobbled/pave racing tire with THE FASTEST 23mm Tufo. If anything, the comparison makes Tufo look badly. It is like comparing Toyo UQTG 540 AA all seasons with Michelin Gt grade slick 220 AA summers. This aside, the esteemed member still had doubts! Let's make it simple: Veloflex is the company's 2nd SLOWEST Elite performance (Slowest being 27mm Vlaanderen).
Also use the new mariposa tape, it is amazing, either front or rear. in the past years, Conti, Vittoria Mastik etc I pulled the tubular so easily I got scared of how poorely they glued and settled. Mariposa? Rock solid on Zipp Firecrests.
Arenbergs are incredibly comfortable; in a stone-ridden region called Saguenay use them as REAR only, and survive a punishing that no other performance tire can handle. A 0.5mm puncture took 1000kms to start leaking. Th eouter rubber had a 7 mm cut, barely noticeable, the inner casing a black 0.5mm hole, and took me a long time to locate the sub 0.5mm hole in the latex. Repaired it easily (opening the tubular). As is, can push 35-45km/hr on flats without problems, and easily descend 60-70 km hr (as fast as my gradients permit). Yet it stays comfortable at 108-115psi (total rider weight 195incl kit), and delivers 3000 + kms per rear.
Arenbergs are slower than Carbon/Sprinter and even more than Veloflex Extreme (the S3 equivalent) , perceptibly so on perfect smooth hot roads. Arenbergs, however, are as fast, maybe even faster, on cool, moist, grimy and imperfect road surfaces, the tire attributes delivering in these conditions where stability and contact are key- over road deformations, over tiny rocks, through cracks etc. The faster, 23 mm types bounce the bike up. In nice conditions, Montreal or Ottawa, use Carbons without problems, won a GranFondo on Vx carbons, and are impeccable. Any bad region, Arenberg's 320 TPI construct deliver flawless performance, stability and control. Not top speed, but we do not mount Arenbergs for top speed, right? Nor do Cx or rally cars use the same rubber as F1 track, and F1 Pirelli has several compounds for races. Nor do pros mount Arenbergs for speed during Paris-Roubaix. Gutting them for repairs, Arenbergs are very smooth inside but also the casing and rubber are VERY THICK, even if soft. Softer than any Conti, Michelin or Tufo I saw opened.
I stay away from Tufo as they do not last in my region- people riding them fille them with Stan's and thus change their characteristics. Poor low mileage and puncture very easily over tiny sharp rocks. In over 30,000kms of high performance cycling, experienced only that one latent flat amongst all Vx Arenbergs and Carbons I rode. And the flat is in that tiny rock infested Saguenay region.
Also avoid Challenge and FMB- they do not last. They are not cured and meant on perfect TDF / Gyro type, pre-race-swept roads. FMB's do not last 6 rides in my training areas, even nicer Ottawa streets. One chip guts them.
On my secondary bike I run Continental Force Comp 24 mm rear (22 OR 23 mm Contis in front), and the top race conti is an unstable, rigid tubular. it becomes manageable around 105 PSI. 120 or above is just jumps or skids, and does not round well under fast cornering.
Had the author compared the Tufos with Carbon or Extreme, then maybe the comparison would have made sense. But comparing the much heavier, poor weather/poor road, nonetheless elite Arenberg performance tire (and what a poor performer at pro level speeds!!), versus the Tufo fast speed/TT, is not a valid comparison. Gut them once they are done and feel the difference, and one can understand.
Arenbergs are so good they are very hard to find these days (gone from most popular sites) and from 12+ months stamped date, lately received 2016 stamped Veloflexes (means high demand). If possible, I age them 6-18 months if past the manufacturing date stamped on them.
