Who's Afraid of Toe Overlap?

The idea of "toe overlap" or "toe clip overlap" (TCO) is one of those hot button topics that can causemetaphorical bloodshed in online discussionsamong bicycle enthusiasts. Still, I would like to have a go at it, as I think my perspective reflects the type of cyclist who does not typically take part in these debates. I would also like to discuss the topic from both sides of the argument, encouraging readers to form their own opinions. In short, here are my 2 cents:

What is toe overlap?On some bicycles, it is possible to hit the front wheel with your toe when turning at slow speeds. This interference (or overlap) between your toe and the wheel can make you fall. Toe overlap is especially common on bicycles with small frame sizes and large wheels. If you picture what happens to the wheels of a bike as the frame gets smaller (as the top tube gets shorter, the wheels move closer together), it makes sense why that is so.

Is toe overlap a problem?

I don't think there is an answer to this question that rings true for everyone, but I will try to cover multiple sides of the argument.



An argument for "no": Chances are that you alreadyhave a bike with toe overlap and simply haven't noticed. Try it: make a slow, sharp U-turn on a quiet street or in a parking lot, and pay attention to whether your toe can potentially hit the wheel as you are making the turn. The overlap is more drastic on some bikes than on others, but most smaller-frame production bicycles have it to some degree. The reason many cyclists remain blissfully unaware of it, is that we rarely cycle at speeds slow enough for the wheel to turn so sharply as to cause the overlap. So while the overlap is a theoretical possibility, it is not usually a threat.



An argument for "yes": Cyclists do occasionally make turns slow enough to cause toe overlap. Instances when that might happen include the aforementioned U-turns, as well as slow turns in urban traffic. In addition, beginner cyclists tend to go slower than experienced cyclists - making them more vulnerable to toe overlap.



An argument for "no": Some in the bicycle industry will argue that toe overlap is not so much a "problem" as a reality, and it is the cyclist's responsibility to learn to deal with it. Even on bikes with dramatic toe overlap, and even when those bikes are fixed gear (i.e. coasting through a turn is not an option), there is a way to time your pedal strokes so that your toe does not hit the turned wheel. There are formulas and instructions for this. Over time, it becomes "second nature."



An argument for "yes": What is "second nature" to some, may not be to others, even over time. There are some experienced cyclists who've had bad falls as a result of toe overlap. The bottom line is, that if your bike has toe overlap, and if you actually manage to hit the front wheel with your toe as a result (or get your toe jammed in there, which also happens), you could have a bad fall while trying to execute a turn. Therefore, at least in theory, a bike with toe overlap is more accident prone, than a bike without. Some would argue that this in itself makes it a "problem" and not just a "feature" of the bike.



What can be done to avoid toe overlap on small size bikes?

In theory, a few things can be done by the framebuilder or manufacturer to create small size frames without toe overlap. The problem is, that all of these changes have consequences that can be perceived as drawbacks. For example:



Smaller wheel size: Toe overlap can usually be eliminated on a small frame by fitting the bike with proportionally smaller wheels. For instance: 650B instead of the typical 700C on a roadbike, or 26" instead of the typical 28" on a roadster-type bicycle. The reason this is seldom done on production bikes, is that it is more costly for a manufacturer to design different sized frames around different wheels. Additionally, cyclists themselves tend to have an aversion to smaller wheels, due to a commonly held belief that larger wheels are faster. This makes smaller wheeled bikes less popular, despite their no-TCO advantage.



Changes in frame geometry: Toe overlap can also be eliminated by a number of changes to frame geometry. The simplest method is to make the the top tube a bit longer and the seat tube a bit steeper, which will create more space between the front wheel and the crankset without changing the way a bicycle handles too much. However, a longer top tube means that you will either be too stretched out on the bike, or will need a super-short stem. And a steep seat tube means that you may either be uncomfortable with the aggressive angle, or will need to find a seat post with considerable set-back. If you prefer a relaxed seat tube angle and a reasonable top tube length,then the other options are more complicated, as they involve messing with the bicycle's handling: Making the head tube slacker and increasing the fork rake will reduce toe overlap as well, but it could make the bicycle less responsive, which many cyclists would find undesirable. I don't want to turn this into a lesson in frame geometry, but suffice to say that some would prefer to deal with the toe overlap, rather than make either of these changes to their bike.



Conclusions?

It is hard to find a definitive answer to the questions of whether toe overlap is a problem, and of how to eliminate it. Different frame builders, bicycle fitters, and other industry spokespersons will tell you different things, and they may all sound perfectly convincing and reasonable while you are listening to them... until you hear the other guy's argument for the opposite, and it will sound equally convincing and reasonable.



My personal view is that toe overlap is a problem if you consider it a problem. And if you do, then I don't think it's right for anybody in the bicycle industry to try and persuade you otherwise in order to sell you a bike. Ultimately, it should be up to the cyclist to decide and for the framebuilder, or salesperson, to accommodate.

The California poppies are in full bloom on top of the Cal Poly "P" ridge. The "P" is a large monument-like letter engraved in the hillside above the Cal Poly campus. The ridge above the "P" is covered in wildflowers right now.

Icy Afternoon

Here's a photo from a couple of days ago, before the weather turned cold. We took a walk through the woods and along the shoreline in Grand Portage and found this beach that was covered in ice chunks both on the beach and rolling around in the waves. Even though this winter has not been up to snuff in terms of snowfall and major ice build-up, I have still been finding lots of fun ice to photograph. Today the sky is gray and it is snowing, so enjoy this photo from a sunshiney day!

Coco the Obedient One...Sort of....

Anyone who know Auburn and Ace, knows how well trained Ace is. Coco, on the other hand, not so much. Don't get me wrong. She is a great dog. We don't have any trouble with her. It's just comical to us to see her version of dog obedience after being around Auburn and Ace.



Here she is walking with Aric. I love this picture of the two of them. She seems fully engrossed into listening to him. She seems to be saying, I am your dog. You are my boy.

You are Master. I am dog. Lie down....no problem!

I'll just stay here. With you. Until you let me know when I can get up. Or until.....

something else distracts me and I forget all about you....

Another creek shot from last weekend in Las Trampas.

Right now California is being pounded by yet another strong rainstorm, and this one has dropped a few inches of rain in places. As the storm heads inland tomorrow, it will leave behind showery weather for what appears to be the remainder of the week.

All the while, the rain has caused the wildflowers to start growing and budding with high intensity, as evidenced by the poppies coming up all over the hillsides. On a recent hike, you could see that the poppies had flower buds...yes!

RootsTech :: Day Two

It was another busy and mind-boggling day at RootsTech. I didn't do much socializing since I attended presentations all day long!



As with yesterday, the keynote address was impressive with a nearly full room of attentive genealogists. Given by an enthusiastic and very dynamic speaker - Josh Coates – the topic was “Exabytes, Social Clouds, and Other Monstrosities.”



I've never tried Voice Recognition Software but after listening to Luana Darby in “Can You Hear Me Now? Voice Recognition Software and Genealogy” I may just have to give it a try! Someday. (I'm not sure my little netbook is capable of effectively using the software.) I have a lot of obituaries, deeds, wills, and estate files that need transcribing and it seems it may be easier to read/dictate them into the computer rather than trying to type up the documents myself! The obits could probably be done by scanning then doing OCR on them but that always seems to require some cleaning up of the text. It seems that Voice Recognition Software has come a long way in the last 10 years or so. The software still requires “training” to your voice and your manner of speaking but she says the accuracy is quite good.



Jill Ball did a great job directing the panel in “Genealogy 2.0: International Panelists Discuss Their Use of Social Media to Connect With Cousins, Collaborate on Projects, Discuss Issues, Market and Promote Genealogy Services and Perform Acts of Genealogical Kindness.” Jill, Amy Coffin, and Audrey Collins offered up examples and opinions on the various topics listed in the title of the presentation.



I seem to be attending sessions on topics where I have limited knowledge. Kinexxions is on blogger but I went to the presentation on Understanding WordPress by Amy Johnson Crow. Each platform has it's pros and cons and since I've got five years worth of posts on blogger, I don't think I'll be switching it over to WordPress. However, I would certainly consider using WordPress for a new blog – if I ever decide to start another one!



My last presentation for today was “Google's Toolbar and Genealogy” by David Barney. I learned so much during this presentation that my head was spinning! If you get a chance, I highly recommend watching this one when it becomes available on FamilySearch. It should be available soon along with the keynote addresses and other sessions.



I didn't take any photos today other than the one below...





Elyse Doerflinger and Michele Goodrum were “caught” doing what many other genealogists did after the sessions were over for the day! Michele is holding a wand scanner that she had been using to scan pages of a book – she says it works great once you get the hang of working with it.



As you can see, the place was pretty busy. I decided not to attempt any research since I'll be staying in Salt Lake City for a while after the conference is over. I also opted to not stay for the viewing of “Who Do You Think You Are?” though I did watch the show from the comfort of my motel room!

Dolphin Fun

I just realized while catching up on reading blogs, that I never came back and posted the dolphin pictures. I guess with all of my new computer fun and a visit from Aric, it completely left my mind to blog. The completely leaving my mind seems to be happening more and more lately but that's a story for another day. Back to the dolphins. When we got to the pier, I could hear there was some hype over something in the water. You can never tell just what that might mean with the ocean. So it was a happy surprise to see that it was dolphins that were visiting.



This is one of those times that I'm so glad I am the weirdo that brings her big camera to the beach with her. While everyone else was using their phones to get pictures, I got some decent shots with a real camera.



It was interesting to watch dolphins here vs somewhere like Sea World. They were just doing their thing being dolphins instead of doing tricks to get treats. Pretty cool. The only downside is they didn't surface much so we couldn't see them that well. Again, they were just being dolphins and weren't worried about us in the least so that is understandable. Then someone went to wash their fish at the fish cleaning station and the water trickled down below.



The dolphins seemed to love this and they fought to get underneath the water from that point on. This is where the real life dolphin show became a blast for us humans that happened to be there.



It turned this into one of my best beach days ever.



We stood there for a very long time. I snapped hundreds of pictures. I murmured things like this is so cool, oh my gosh, oh my gosh, oh my gosh, this is awesome! over and over. I told Nathan later that it was right up there with whale watching because we were so close to them. He smiled at me in that way he does sometimes like he is amused at my simple mindedness.




That's ok. He didn't read Island of the Blue Dolphins 433 times as a child like I did. And he laughed non-stop at a movie recently that I am pretty sure was made for ten year old boys. So we're even!




It was way awesome. Just ask the dolphins!
