Tubular (Sew-up) Race Tires

The high thread count casing and wrap-around 'tread' make this a durable product. Its low mass and low rolling resistance, coupled with the relatively firm compliance (relative to, say, an old 'Strada 66' from yesteryear) have made this my choice for current and future ongoing front-tire shoes. As my front tires seem to last many times as long as my rears, and since I resolve that I am "worthy" of riding tubulars for esthetic reasons, I love these taking the lead on my training rides, long or short! (Though I no longer have the passion to race, I would still use these were I still "in the pack!"

They glue up securely, and I've not had a delamination nor a seam failure. Pumped up well-beyond what a lesser would tolerate, they seem incapable of puncture! (Knock on wood! That was stupid of me!) The 'black chilli' compound seems to be a solid advance in rubber technology, too, combining traction and durability in ways best described as "magic!"

"Let it roll; down the highway"!!

New 2024 model has removable valve cores for those of us with deep dish tubulars. First off, lower your expectations: these are training sew ups with butyl tubes. Out of the package they're lumpier than your grandmas favorite mash potato's. But, stretch them properly at high pressure for a couple days & they mount up 'relatively' straight. More than adequate for training tubs at this good price.

One star off since the valve stem area doesn't sit flush & it's bumpy even after rolling them on a broom handle.

Pro Tip: these are cotton sidewalls, buy liquid latex ($10) & brush it on after gluing. This will help seal the super wide basetape & sidewalls'perfect for waterproofing these training tubulars!

I have been riding these tires for several years mostly on Chicago streets.

they give a smooth lively feel and tolerate the city's bumps well. They are easy to work with, given a tubular classification. Out of eight purchases one was defective (the seam leaked) which bike direct replaced promptly. They tend to give me a season or two and wear down which leads to punctures. However their low price (slowly increasing) is the incentive.

What is the Giro? It's an old-fashioned affordable, 2-ply "Cotton" tubular. It's great for the money. Very well made and good quality. If this is the most you can spend, and must ride tubulars, they're a great tire; just keep your eyes peeled for anything that could cause you a puncture - and roll your tires every time you go through any suspect foreign objects on the road. Strive to ride clean asphalt, keep a sharp lookout, and with a little luck you could wear these tires out.
