please excuse my sidebar,
buzzman, where in the berkshires are you. I was just out there for an overnight in adams, n adams & williamstown. there are some serious hills out there for sure. hope you got better tires for those descents, can't imagine a flat then would be pleasant |

Evidently it is not rolling terrain. Mine is about 500 feet change according to googling elevation points...so I go down 200 feet in about a mile, then I'm at the river. Cross river, and start climbing 500 feet over 8 miles with a couple of miles of flat here and there. Sounds like nothing compared to your climb but again, so conditioned to 12 miles right next to the Pacific Ocean, don't think I could've gotten a flatter commute if it tried. I'm going to look into a few options. Also seems like my bike doesn't climb efficiently out of the saddle. Got a trek 520, maybe it's my Arms and legs that are noodly and not the frame....running 32s nothing too fat, good tire pressure. Going to do a few adjustments, and keep truckin! To Rumrun- I'm in Becket at the top of a mountain I leave my front door and am hitting 40 mph within a couple of minutes without spinning the pedals. Coming home is a little tougher.;) |
IF you are managing with the 30:32 combo, I'd just change the cassette and see how that works. You might not need any other changes that might affect shifting quality on the front.

This would be like looking at a cross country bike ride of 3000 miles where the highest elevation was 6500' and saying the average grade was so minimal I would not need much gearing. Can't we just take the OP at his word and help him figure out how to make his new commute a fun challenge rather than a grueling trial every day. My reason for asking about elevation gain was simply to figure out what kind of climbing the commute involved- short steep climbs? One long climb? A bunch of "rollers"? IMO, this helps in knowing what kind of gearing, bike choice, tire sizes and riding style would best help the rider. One other strategy is a training strategy. Often commuting cyclists use their commutes and transportation needs as the sole means by which they achieve fitness and that can be effective. But when you get a sudden change in your commute, like the OP, sometimes it's worth it to devote some time to some training rides. Taking a day and finding the toughest, steepest, longest climb you can and doing a series of hill repeats until you can't do one more and then giving yourself a couple of days for recovery and then going back to your commute may make those hills feel like nothing in no time. (Repeat as necessary) |

8 miles, up.
Ok, I got mapmyride, but I guess I didn't hit record, and didnt realize it recorded elevation, so Thursday I will hit record and submit the results. It is rolling, but rolling up apparently. The uphills on the way home are nothing, no concerns and have 3 very decent descents, ended abruptly by stop lights, signs, etc. the overall change in elevation, again, is not a crazy amount, but it kicks my butt. Hoping in a few months it will be much easier since my body and brain are a little more used to it.

Be advised that Shimano doesn't recommend using the 12-36 cassette on regular road hubs due to the torque you can generate with that 36T cog:
Shimano HG61 9-Speed Cassettes. FW6005 12-36t 29'er-specific cassettes must be used with either M529 (6-bolt) or M629 (centerlock) hubs, which are designed and manufactured specifically to withstand the extra torque load exerted by the 36t low gear Use of the 12-36t cassettes with other hubs may result in hub-failure and may void warranty coverage If you can put a smaller granny ring on that triple, that's what I'd do. |

You really think I'd consider changing gearing for 1 %? It's over 12 miles, lots more up than down. I'm used to flat. Why am I even justifying myself?

I remember when the 12-36 first came out. Some people got all excited, like it was going to unleash their climbing prowess. The reality is that it's only one gear inch lower than a 12-34. Extra torque? I think that's shameless hype.

Maybe it's mental but after the mile climb, I feel every single incline. On the way home, none of it bothers me.

Wondered, 8 miles up is over 40,000 feet, air is rather thin that high , and you have 747's flying by.

Didn't get a level and a protractor, sorry. Tried mapquest, google maps, but don't give elevations. I can get up the hills, sometimes have to drop to lowest gear, 30/32. Just want more low gear options, lowest gear doesn't necessarily need to climb a wall, but want a better low range to get more comfortable in the climbs.
So if you state the starting and ending points, a chart will appear magically;) |

So much of it is a mind game. which is why you shouldn't get too caught up in the mapmyride/GPS info. Don't get me wrong it's useful but it can be counterproductive to obsess on it. I have a really good friend who we have now dubbed "Old Fearing Hills" after a road we saw on a ride once called, "Old Fearing Hill Road" this guy is actually a really good rider but he gets totally psyched out by hills. If he knows there's going to be a long climb on a road ride or tour he starts talking about it the night before. He'll know from his Garmin exactly when we're approaching it, when he sees it he'll start to slow down, say stuff like, "Go on ahead. I'll see you at the top." A little part of him gives up, and off the rest of us will go. Once we're out of sight he climbs really well and when he gets to the top he's in great shape but he'll repeat this routine with every hill. Over time you'll learn how to "attack" these hills. Maybe some of them will need an immediate shift down into a considerably lower gear, others may need a more gradual change of gears. Occasionally you may want to stand, though I recommend getting used to doing them seated, especially for a commute- its not a race (unless you want it to be). The main thing is to keep your knees from suffering. Know the difference between "good" pain and "bad" pain. If you're suffering with muscle fatigue that may not be so bad and may be a necessary part of getting stronger but beware of knee pain especially if accompanied by swelling. This is why bike fit and shoe/cleat fit are so important. And also why it's important to "spin" up them (another reason why I don't recommend standing- riders tend to grind their way up standing and it can be really bad for your knees.) Have fun! I get a great vista at the top of my climb and it makes it all worth while, hopefully, you get some rewards from all the work! |

I have been running that cassette on T660 Deore LX touring hubs, Velocity Dyad, hand built wheel set w/o problems on my Origin8 CX700. On lots of hills, loaded bike, trailer, chariot child trailer, etc..... I think potential problems would come in to play in the 29'er setting, off road, running a 22 tooth ring up front. Loads of torque possible. Not what I am doing with mine, though. 39, 50 teeth up front, here. |

The kind of standing you're describing (ie. the TDF) takes miles of training to do proficiently, IMHO. I stand on some hills at times, especially really long climbs so my cautions about standing had to do with developing techniques for hill climbing as someone getting used to it. The kind of seated grinding you describe is exactly what I am suggesting the OP avoid. Again, IMHO, I think it's best to develop the ability to climb seated, while spinning, strengthen the legs, get some climbing technique and then, when you want some extra power work on your standing technique. Since the OP admittedly is not practiced in hill climbing I made the suggestion to remain seated because the kind of error I've seen most often is a kind of desperate alternation between seated pedaling in too high a gear, standing on the pedals for some relief, sitting back down when fatigued by standing and now pedaling in the same high gear at an even slower RPM. All of which is brutal on the knees. By all means, feel free to disagree, ultimately, the OP will develop his own approach to these hills so as many suggestions as possible are probably helpful. |

Those are fair points, and it's possible that Shimano is simply being conservative, as they are known to be. I'm curious why you're running a 50/39 and 12-36 rather than a 50/34 compact and a 12-34... better front shifting? I was running 50/39 on my main road bike up until recently (changed to a 48/39.) :)
Mine is actually an ultegra triple, minus the inner ring. What I had and could make work with the constraints on this bike. 39 teeth is the fewest I can find for the middle ring...... Changed the cassette to a 12-36 to drop the gearing for pulling my two boys up the hills in austin, although I really don't use this bike for that purpose much anymore. I could have also replaced the crank set with a deore lx or deore with touring gearing, just didn't want to drop the $ unnecessarily because I already had a new ultegra crank set, rings, and bottom bracket that I could make work for this build..... I also really like the top end on this bike @ 50/12.......should not technically be possible according to the manufacturer, 48 teeth listed as max chain ring size.... |
I don't recall ever hearing a warning about using a 12-34 on a road hub, and, I have seen plenty of people do it. I don't think the "massive" torque of one gear inch is going to matter.

If you think the quoted text is marketing hype, you're reading it far differently than intended -- which is that the road hubs (in particular the ratchet mechanism) are about as strong as they need to be for smaller cogs, and 36T pushes them past their design.

I totally agree with you on that. There's so much more muscular engagement when standing.

Like I said earlier, I think a smaller granny ring is a better solution anyway. That, and getting in better shape if they're considering such low gearing. |

I get a great vista at the top of my climb and it makes it all worth while, hopefully, you get some rewards from all the work! Another thought for 'so much of it is a mind game'. I have young boys (currently 7-12yo) that I am trying to raise right in the cult of cycling, so it is a little bit of a milestone when each of them "finally climbs Fletcher Parkway" or can say "I've conquered Fanita". When I ride loops from the house, I have climbs that destroy me every time. And yet, if I bring a boy along, it's easy peasy. The reason is that I slow down to their speed. So I try to keep perspective in my head, (almost) any hill is climbable. The real limit for me is about 3mph in my 34/34 low gear, any slower and balance becomes an issue. I don't know how to translate that into percentage grade where 34/34 @ 3mph takes my sustainable wattage though. Maybe like 10% or so? I dunno; even though I'm an "Old Fearing Hills" I don't have a good feel for judging grades by eye. |
