Tubular tires seem to be going out of style these days, but there is still a very loyal following of people who love the supple feel and unmatched ride quality of a tubular tire. As I noted back in my Vittoria Rubino Pro III review, there’s a huge spectrum of tires, from the “lightweight and supple for racing on smooth roads, durable, high volume and puncture resistent for riding gravel grinders, or somewhere in between for everyday training tires.” In the case of Zipp’s Tangente Tubulars, we’re talking not about a high durability training tire, but a lighter weight racing tubular. And after a season of riding (and racing) Tangentes, here are my thoughts on these “aerodynamic wonders.”
It’s been well advertised that the SRAM Red Yaw front derailleur has revolutionized mechanical front shifting. Tom Boonen won a pair of monuments on it last year. One could arguably claim that the simple concept of an uneven parallelogram that pivots about the seat tube, negating the need for a trim function and packaged into a lightweight and (importantly) stiff front dérailleur is the crown jewel of the new Red group. But does this seemingly unsung piece of metal really live up to the hype?
After the jump I’ll examine my experience with the Yaw unit over the past eight months and figure out if it lives up to the hype.
After managing to put paid to my third Cinqo power meter, Quarq went above and beyond the call of warranty service and upgraded me to a Red Exogram power meter to replace the problem child Cinqo. I detailed the warranty process in this post, so you can read about it in detail there. Suffice to say, Quarq was wonderful throughout the process and I feel confident recommending them and their power meter units to anyone.
As for the Red Exogram model, while it may look similar, in reality it is a radical departure from the (now discontinued) Cinqo model, both in terms of the power meter spider and the SRAM crank components themselves.
After the jump we’ll take a look at the Exogram unit as a whole and as a sum of its parts.
The Giro del Cielo is a 2 day stage race in Sussex County, New Jersey. Originally begun as a women’s only race, in the 9 years or so that it’s been in existence, organizers have added men’s cat 3 and 4/5 fields. USA Cycling sanctioned, the 2 day/3 stage event is a great way to introduce people to stage racing without forcing them to commit to something as brutal as the Green Mountain Stage Race, Tour of the Catskills or the like. It’s geographical location in northern New Jersey is also the perfect venue to draw a diverse group of racers and teams, ranging from local squads to teams and riders from New York City and Philadelphia.
I’ll go through my experience stage by stage, discussing some of the things that worked, some of the things that didn’t, and how to improve for next year. I’ll cover:
- Time Trial warmup – Getting your body primed for a hard, constant effort
- TT recap
- Post TT recovery – How to make sure the legs are fresh for a second race that day
- Crit race warmup – Getting your leg speed online
- Crit race recap
- Day 1 recovery – The key to riding strong on day 2
- Circuit race warmup – Getting the legs moving after a couple hard efforts the day before
- Circuit race recap
- Overall impression of the race and of my performance
Since the weather became nice enough to start using tubular wheels again, the eternal frustration with valve extenders has become yet again apparent. Adding to the frustration is the fact that I’m a devout user of the Lezyne Alloy Floor Drive pump (which screws on to both presta and schrader valve stems) and that just doesn’t work with a non-threaded valve extender.
And let’s face it…that old Park floor pump I have in the garage is a piece of junk at best.
Enter the machined aluminum, laser etched beauty that is the Lezyne alloy 70mm valve extender. With a presta threaded top on it, wrench flats to ensure proper torque on the stock valve and a little baggie (I do mean little, it almost requires tweezers to open and I have fairly thin fingers) full of o-rings to make a perfect airtight seal, these things are more than worth the fifteen bucks that I paid for them.
As well as looking awesome, they function extremely well (at least as well as a piece as simple as a valve extender can.) They threaded presta cap means you can use the awesome screw on Lezyne pump or you can use any standard pump you want, making life infinitely easier.
The biggest downside to these extenders is that they screw onto the top of the existing valve stem and merely provide a conduit for air to get from the pump head to the valve. I’d prefer if the extender actually moved the valve parts out to the end of the valve extender, much like the ENVE extenders do. The issue with these extenders is simply that in order to access the valve (to open or close it, or to remove it to spray in Stans or anything similar) you have to remove the valve extender, and it may still be impossible to access the valve stem anyway (otherwise you wouldn’t be using extenders.) That aside, I’ve had no issues with them, especially as they relate to the Lezyne Floor Drive pump.
The only other thing one could wish for was stealth black with the sweet laser etched “Lezyne” logo on it. But the polished silver certainly looks the part.
