Time to test the hip
My standing weekly ritual is to train at Lemonade fitness on Tuesday & Thursday mornings. Today was no different. However, I had Don change the routine to 3 by's instead of 2 by's and turn down the wattage to 200 watts for 45 minutes. The hip felt ok until I decided to increase my cadence. At 95-100 rpm my hip was telling me to slow down a little. I finished the rest of the workout averaging 85 rpm. By riding this way I know I'm good to go for the weekend.
Off to to do some more riding:)

A day to Reflect & Recover
Today I try and recreate in my mind what unfolded in a split second yesterday. I pride myself of always being on alert and aware of my surroundings, which has kept me from crashing in the past. As many times as I keep replaying yesterdays crash. I never saw the cattle dog that ran out in front of me. I didn't have a chance to brake, swerve or do anything evasive. I guess as much as I ride things like are bound to happen without explanation.
I'm not feeling to bad today but I am sore. Trying to raise my right arm above my head proved to a challenge this morning while trying to wash my hair. My right hip has some road rash and the purple bruising is starting to show.
Maybe a little more scotch today to help ease the pain. Planning to try and ride again tomorrow:)

Back to Back Outdoor Rides
Saturday 40 miles 2:22 with temperatures of 30 at the start and 38 at the end.
Sunday 33 miles 2:03 with temperatures of 44 at the start and 41 at the end.
Saturday's ride was very cold, but the roads were clear and traffic was low. It was really a beautiful day to be outside. The fields were covered with clean white snow from record snow falls in February. We have only had a few days above freezing since the last snow so the fields had a glass like glaze over the white untouched blanket. Dropped over this blanket of snow was a crystal clear blue sky with absolutely no wind, which is very rare in Central Ohio.
The pace was a little high to start the first outdoor ride for many. In the first 1/2 mile we were on a 18.5 mph pace, at 30 degrees it doesn't take long to warm up. Of course with a self created wind chill of 17 degrees it does take a little extra time to warm up. As we moved out into the country into Johnstown and Croton it was interesting to see the ice still on the branches of the trees. Evergreens and dogwoods stilled covered in ice and frost, yet here we are riding at around 20 mph in a double pace line. The shame of it was I forgot the camera. This setting is not without a few new challenges for the cyclist, things like new potholes and icy patches under a melting surface. These things and learning to ride in a group again always makes the first few rides of the year keeps the rider on their toes. There were a few stretches where we were riding very well as a unit and the pace was up around 20-22 mph, the sun was warm, the pace was good and I was feeling fairly strong. I wanted to shout out in utter joy at finally being able to be outside and doing something that I truly enjoy.
Sunday was a lot warmer in the 40s. The wind had picked up a little, but still a very pleasant day. For the second day in a row we had over 15 riders for the early spring @teamroll ride. This ride took us through Delaware, Knox, and Morrow counties. Once again the rolling snow white fields were beautiful under another clear blue sky.
And yes some of us will eat almost anything before we ride. The GUs are good for a ride but the gloves are a little hard to break down in the digestive system.
Sunday 33 miles 2:03 with temperatures of 44 at the start and 41 at the end.

This ride took us through Delaware, Knox, and Morrow counties. Once again the rolling snow white fields were beautiful under another clear blue sky.
The route was flat for the cutoff group, another group headed to Hogback Road in Delaware which is a local climb. Eight of us took the shorter route and we were riding along very well in a nice double pace line. Then out of no where this dog pops out from the trees. No one saw it and no one had time to react. This dog runs right into Rick who was riding beside me. I tried to move to the left and give him a way out, but as soon as I took one pedal stroke to the left Rick was on his side. My rear tire ran over something, I'm not sure if it was the dog or Rick's wheel. This happened on Carter's Corner or Wilson Roads, I think. The good news is Rick was only mildly banged up, some abrasions, damaged clothes, and soreness tomorrow. But no broken bones, spokes, or rims so that is a good thing. It was a small dog, but getting t-boned at 20 mph will always bring you down.

Shimano Ultegra Chain Failure
New "Equipment Misbehavior". A reader from the Netherlands (who wishes not to be named) alerted me to his concern that lately, a large batch of Shimano Ultegra chains (CN 6700) have been breaking with use. These chains are narrow and lightweight, meant for performance riders. I'm not aware of what its roller diameter, plate width etc are. Can anyone help us here?
Anyway, so he was personally riding a steep cobbled climb last Thursday when his chain, 700 kms old, broke on one side of a link. Interestingly, he was able to get home and install a spare new 6700 chain as replacement. Well, guess what. A little after 7 hours and 220kms of riding over Saturday and Sunday, that chain also happened to fail. That's not a good thing to happen to someone who's stranded in the middle of nowhere.
He decided to call Shimano Europe and found their response to his problem as quite rude. In his own words :
"Shimano is still denying the problems, but many people have problems with the 6700 chains. I spoke to someone from Shimano Europe on the phone this morning, which wasn't pleasing since he was quite rude. For me it is not about the money, but all about the risk. The question is if someone is going to crash because of these breaking chains, when and how many crashes are there are going to be? Often there is quite a lot of difference in customer support between Europe and North America. For example Zipp seems to have a great service in the States, but in the Benelux it simply sucks. But the attitude of Shimano seems to be bad everywhere. "
He examined the first chain he broke and found 15 different cracks all over the place. The second chain he broke had 11. He's having the chains sent to another company, who will then X-ray examine them for deficiencies. As and when I get any more news on that, I will post it here.
Notice the interesting manner of crack formation at the two ends of the chain
Now roller chains are reliable over a wide range of temperature conditions. So if the Netherlands has had a really bad weather this year in terms of winter and salt on the roads, should it matter if the chain is well maintained? The individual who contacted me reported that he regularly washes his chain in plain hot water to get rid of salt.
As to the question of whether he applies any other chemicals to the chain for cleaning, I do not know. Shimano does protect their bottom to some extent by calling out the following in their technical instructions.
For chains to avoid breaking in fatigue, the operator has to restrict stresses to those below the corrected endurance limit for the material. The total load in a chain is a sum of the tangential driving force, centrifugal tension in chain and the tension in the chain due to sagging.
But even still, a chain should NEVER break. The only evidence of deterioration in a chain should be elongation due to steady wear. But that usually happens only after 1000-2000 hours of usage in well lubricated chains. They should be pretty reliable otherwise. For a new Shimano chain to break in 7 hours may point to something unassured in its design/manufacturing.
Have any of you experienced similar problems with these chains as well as Shimano's deteriorating customer service?
