    Re: Cassette change question on 2013 R3

    ApexR3:

    Thanks for the images.  I contacted my LBS and they said to go with an 11-28 since the derailleur is the regular short cage and not the 6700A short cage.  The pivot points are different on the 6700A to work with the 12-30 cassette.  I'll see how things go with the 52/36 - 11/28 combo goes and if I need more help on the hills I'll go with 50/34 chainrings. 

    Apex - I live in the lakes region of New Hampshire and we have a lot of steep short climbs.  When I first move there I was running a standard double crank set up in the front and switched over to a 27t cassette as that was the largest Shimano offered at the time.  I made sure to get a compact crank and 28t cassette when I got my S5.  What I noticed was that climbing was easier, but it wasn't really super easy until I dropped about 20lbs and then I found myself not only beating stronger riders up Hurricane Mt (a notorious steep 2 mile climb) but also flying up shorter climbs seated in the big ring.  Gearing helps, but ultimately I feel it's rider weight that makes a bigger difference.

    Jens Voigt doesn't complain about what suffering does to him, but suffering constantly complains about getting picked on by Jens Voigt.

    Totally agree with the rider weight!

    Re: Cassette change question on 2013 R3

    I'm 5'6" about 145lbs with a mix of a mesomorph/endomorph body type.  I could probably lose about 5-8 more lbs, but any more and I'd be losing muscle.  Thing is, I have a blood trait called Alpha Thalassemia minor (common amongst South East Asians) which affects my endurance since my RBC's are slightly smaller than normal and can't carry as much oxygen.  Did not find this out until I was an adult and explains why I was very explosive when playing lacrosse and in wrestling, but I would have endurance issues playing longer minutes and in longer wrestling matches. My Dad has it and he never told me that I had it so I wouldn't use it as a crutch playing sports.

    Anyhow, Dr's claim it shouldn't affect me, but it does especially as I age.  I have to work that much harder to keep up when it comes to endurance sports.  For instance, someone my same age (42) who can put out X amt of power at say an HR of 150, I would have to go to an HR of 170 to put out the same power.  I don't road race, just an occassional local MTB race every summer, but I do want to get faster and stronger as time goes on.  So the goal for me now is to have a gear ratio available where I'm not redlining, yet fast enough to hang in group B/C rides and when I'm base building I'm keeping my HR below 80% for my rides - so compact seems to work well for me.  After base building this winter and testing last week, I feel much stronger and my HR is lower overall which means the base building is helping.  I've also figured out I need more recovery time between hard training rides.

    Re: Cassette change question on 2013 R3

    Did a longer ride today on the 11-28, didn't get out out the big ring (lol). But think about keeping it on after the big hill ride. Noticed that I like to run 50 to 19/17 most of the time when riding. With the 11-28 I seem to have a better chain line as this is the 4th/5th cogs. Any guys out there that ride in flatter places see a good reason to switch back to the 11-23 for the week to week ride?

    Have you considered 11-26?

    i use 50 - 34 and 13 - 25 (ultegra 6600) which has an 18, the cog I use most for cruising speeds of 32 - 35 km/h 

    on the flat, i am mostly on 50 - 19, 18, 17

    You will gain an intermediate cog or so, but I'd stick with the 11-28, For now. Just when you're out riding around and you come across some ridiculous hill, or push it way to far and just want to get home when some 30 mph headwinds winds kick up (happens in Maui all the time) you'll wish you hadn't stepped back down to it. Save the cassette for a flat TT, Disc, or to utilize the 11T cog and lockring to convert a 12-27 to an 11-27. Put it on a back up wheel and toss it on some time..

    I'd say forget about it for a few months! Extra intermediate cogs are nice but I've found when I want one, I just either push harder or 'work on' my higher cadence training..

    Aloha,

    Jeff

    Will did the B2B but a few things went a rye. 1st the Garmin's magnet spun on the spoke and stuff up the readings for distance and speed. Next the cassette locking nut came loose and wound out. So after doing 90kms of the 110kms I could not pedal anymore. Could free wheel forward but not roll RS backwards and the pedal/cranks would not move the chain. So had a DNF with only 18kms to go and all the hard work done. http://app.strava.com/activities/50057298 Was recorded as 70kms but was 90kms. Simon P

    Re: Cassette change question on 2013 R3

    Update: I rode the new cassette (11-28) last night, with 50/34 up front on my S2. Going from a 11-25 to the new one on hilly rolling terrain made the S2 a different beast altogether. I didn't push it at all, and even sat up on some of the hills, but the easier gearing and increased cadence brought me from about 10kph on the steeper hills to 12-13kph with the new cassette. I checked my ride on Strava, and posted 2nds and 3rds (my own performances) on 5 climbs that I routinely do. And that's just on the first ride. I will definitely be posting some PB's on my next few rides.
