On Test: 2012 SRAM Red

I hemmed, and I hawed.  The previous generation of SRAM Red was good, the rear shifting was great, the weight was the best, but the front shifting was just never there.  When perfectly set up, it shifted fine, but not exceptionally.

After a few years of experience, SRAM kicked out 2012 Red, which has addressed all of the major concerns of their top-level group.

Ergonomics were always one of the strongest points of SRAM, so the change to a new lever shape concerned me.  But what works for me doesn't necessarily work for everyone, and we heard some people talking about a sharp edge on the back of the lever bothering some hands.  SRAM addressed this issue by smoothing the transition from the lever to the bars and adding some rubber inserts if someone still feels some pressure at the rear of the lever.

For years I settled on SRAM's front shifting to get it's amazing weight and to support the local boys.  Last winter I strayed to Shimano, drawn in by their industry-standard front shifting.  It was great, Shimano did exactly what they claimed.  Shifting was spot-on every time, front shifting was incredibly fast.

With the introduction of 2012 SRAM Red, the boys down on Kingsbury addressed a number of things but most importantly the front shifting.  The new Yaw front derailleur doesn't move like others, it actually moves laterally and slightly rotates to improve shifting.  In doing this, it also eliminates the need for a trim setting.  I was skeptical, but after being around this system for a couple of months I'm impressed.

The integrated chain spotter is a really nice touch as it's independently adjustable from the front derailleur.  Get your derailleur in place, then use the separate bolt to attach the spotter later.  A brilliant design.

The rear derailleur didn't see the same type of overhaul the front derailleur and shifters saw, which is just fine by me.  The shifts are crisp as always with a light touch but a positive engagement.

So here's the test rig.  If shifting in the stand, or on my short test ride, are any indication, this stuff will be sweet.  Now, if the front shifting remains great under power the way it did in the stand, SRAM will have a homerun with their new Red group.  It's only a matter of (not very much) time before the tech trickles down to Force-level where things will really get great for the masses!

New Review: Schwalbe Sammy Slick 700x35

I long for a good file tread.  One that provides minimum rolling resistance but good cornering grip.  Not asking for a lot, right?  Right.

I've long enjoyed the Challenge Griffo XS for training, but cornering with that is akin to riding road tires on ice.  The casing is supple so the ride is smooth, and man does it roll fast.

Not long ago I put a fair number of miles on the Clement LAS, which was awesome.  Great volume, very fast rolling, supple enough, and a nice shoulder that provided some great grip.  Come to think of it, my only complaint was that I was never able to set them up tubeless, but they weren't rated for that anyway.

So here I am, with a file tread I like, but that doesn't mean I should stop there.  Schwalbe's Sammy Slick appealed to me because of the shoulder it offers as well as the luck I've had in the past setting Schwalbe tires up tubeless.  I haven't tried that yet, but the tight bead of these tires I'm hoping will easy to seal up.

The tires are labeled as a 700x35, but set up on my Mavic R-SYS SLR's the casing measured a tiny 31mm, the widest point on the tread was a dismal 32.8.  Bummer since I was digging the idea of a 35mm tire.  Even more of a bummer, the tires are very short, meaning they have very little volume.  Advertised weight was 360g, mine were 325g and 355g.

On a very smooth course, I could see these tires being exceptionally fast.  Unfortunately, on a bumpy course the lack of volume would either force you to stay with low pressure and risk a pinch flat or raise the pressure and forgo grip and comfort.

I'm only a couple of rides into these tires, but so far I can say they roll exceptionally fast when the going is smooth.  The shoulder also grips quite well for a file tread, even when I was doing some hot laps at my favorite hidden gem along the North Branch Trail which offers up a lot of gravel.  The tires are pretty light, so they do spin up fast.

The Sammy Slick strikes me as the perfect tire for The Des Plaines River Trail or if you find yourself hitting some gravel roads.  You'd fly on a smooth and grassy cyclocross course, especially if that course offered some off-camber turns where most other people running file treads would find themselves slipping around.  Unfortunately because of it's narrow size and small volume, I wouldn't recommend these on a bumpy course where the risk of pinch flats would be very high.

This is What Spoiled Looks Like

Riding around these parts just doesn't get much better.  Roll from my house and I'm at the Des Plaines River Trail in 20 minutes.  Ride gravel north as long as I want.  Repeat.

Yesterday's weather was beautiful.  The trails were wide open.  Welcome back summer.

First Rides: Mavic R-SYS SLR Wheelset

I have to admit to these wheels sitting around for the first couple of weeks I had them to test.  It's not my fault, Lumberjack 100 is right around the corner so I've been on my mountain bike.  But, it's about time to log some faster miles to feel better about myself.

 A few rides and I'm starting to form an opinion on these wheels:

First, they are a time-trialists worst nightmare.  They spin up fast and gain speed like crazy, but the boxy rim and fat carbon spokes are about as aerodynamic as a CTA bus.

Second, the Exalith braking surface is incredible.  Out of the box with Exalith-specific pads they whistle like crazy.  Super loud.  I've swapped to stock Shimano alloy-specific pads and the whistling was greatly reduced.  The pads do wear faster on the machined braking surface, but the performance is unreal.

As you can see from these shots, I've taken the wheels out in some wet and on less-than-ideal roads.  Braking performance is perfect, even in the wet.  The brakes aren't grabby and have a really steady power curve.

Third, the tires are holding up well for me.  Chase on the other hand destroyed one on is second ride to a big cut, I'm hoping that's just bad luck.  The tires aren't my favorite, though.  The rear PowerLink tire is made to roll faster, the front GripLink made to, surprise here, grip.  I haven't pushed them too hard into corners, but so far the front seems ok.  The rear on the other hand offers very little grip in the wet.  So little grip in fact that it actually makes me a little nervous to ride in the wet.

Fourth, the rear hub, or more specifically it's engagement.  It works fine, it's been flawless, but the engagement is slower than the Chris King R45 rear hub I'm used to.  It's fast enough, but when you get used to King it's hard to settle for less.  I also like the "buzz" of the King, Mavic freehubs are pretty quiet.  Personal preference here, not a big deal.

Fifth, they are beautiful.  That's a fact.  Not really a fact, my opinion, but they really do look great.

Finally, let's cover stiffness.  Laterally, they are stiff.  Really stiff.  I did a couple of low-speed, big-gear sprints really wrenching on the bike and the wheels just don't flex side to side.  Vertically they ride nicely, but I won't say they are better than a pair of hand-built wheels.

So far, so good.  I like this pair of R-SYS wheels, but I'm not sure I like them $2000 worth.  When in a group ride, I won't ever win a sprint.  The only way I can get some "fame" is to get into a breakaway and try to ride away with a group.  This is not the wheelset for that.  If you like to sprint or treat your wheels like crap, this wheelset may work for you.

More to come....

On test: 2012 Mavic R-SYS SLR

Truth be told, I'm not the world's biggest "wheel system" fan.  Maybe because part of my job is building wheels, or maybe because I enjoy picking each and every component on my bike, or maybe hand-built wheels really are that good.

But when it comes to Mavic there's a lot to like.  Their Ksyrium line is well-known for it's durability, but the R-SYS came out of the gate with a bad rap with a couple of failures.  When something like that happens with new technology, it sticks with people.

I want to like the R-SYS, but I can't in good conscience recommend them to customers until I can feel comfortable with their durability.  What better way to get a feel for these wheels than to ride them!?

With that said, off we go on test.  What am I looking for?  Durability, stiffness, ride quality, and braking performance.  It's pretty easy to see these wheels won't be wowing anyone with their aerodynamics.  Thick spokes and a rim shaped after a brick don't add up to aero savings.  Word on the street though is that the R-SYS line is supposed to be really stiff laterally yet ride nicely.  The new Exalith braking surface is supposed to provide pretty much the best braking this side of hydraulic discs.

On with the test....
