Bike size

I live in East London. Is it possible to send you the appropriate measurements for you to assess what size bike I require? Recently I bought a Cannondale Synapse, frame size 47 compact and it is too small for me. I just cannot get comfortable on it. I have consulted several people who are respected in the cycling fraternity who have confirmed the wrong size, but would like your opinion as well before embarking on buying another frame. Which measurements would you require?

Scott Safier replies:

The short answer is "no", it is not possible to prescribe a frame size strictly based on any body measurements with total confidence that the result will be a bike that is comfortable to ride. I could give you a bunch of questions to answer that might get you close, but I have another suggestion that is almost guaranteed to get you the right size bike. Go to a shop and try bikes. Have the shop employee adjust the bike for you and really test it by riding hard, taking some corners, riding it up a hill and down. Keep trying different bikes until you find one you love. This method guarantees you'll end up with a bike you love.

Insulin pump therapy

I am a 60-year-old cyclist, having been so for 46 years. I raced up to the age of 40, with a little success – a handful of wins and completion of an 8-day stage race as the highlights. At 40 I was diagnosed with type 1 diabetes, and by 50 was suffering from atrial fibrillation, a form of arrhythmia. This curtailed my cycling to 20-mile rides, generally about 90 minutes exercise. In 2002 I started to use an insulin pump to improve my blood sugar control, and removed the pump whilst cycling. In 2006, I had an ablation procedure which cured my fibrillation, and since then with the absence of beta blockers and warfarin, I have improved my ability on the bike, moving up to 3-hour + rides – approx 50 miles.

The downside of my increased endurance is that I finish these rides with high blood sugars, in excess of 15mml/l. I am currently combating this by keeping the pump running on a reduced basal dose (50% of normal, though I can adjust it to any fraction of the standard dose) and stopping every 30 minutes to take a sugar-level reading. I react to each reading by applying more insulin, more carbohydrate, or nothing, as the case may be. Although each stop is brief, I don’t really like stopping at all, and would like some advice from people who have already solved this problem, either for themselves or for others, to help me establish the most effective pump regime for my longer rides.

You need to come to camp! Check out the Stroke-Spin-Stride camp. It was designed just for you! The director has pulled together some of the top coaches, nutritionists, and med staff in the country to come together and produce an integrated camp to address how to manage diabetes and exercise for optimal performance.

The camp was also featured in Newsweek this week.

If you contact them through the website they may be able to answer your questions more in depth regarding how to regulate blood sugars during a ride.

Leg length

My left leg has been measured by an experienced bike fitter at 3mm shorter than my right leg. My saddle is set up for full extension of my left leg (short leg). However, my saddle feels low. If I raise my saddle 2mm more that puts too much of a strain on my left hamstring. What would be your recommendation for a shim thickness if any and corresponding saddle height change.

Frank DePasquale

David Fleckenstein replies:

Before recommending any shim changes, I have two issues of concern. I would very seriously question the ability of anyone to consistently measure a 3 mm difference in leg length - research shows us that these measurements have poor validity and the only true way to measure leg length is with long leg x-rays. Secondly, I would question whether you have a true leg length difference or a functional difference due to pelvic rotation/shear and would recommend having this evaluated by a PT or chiro. The concern with shimming to make up the functional difference is that rather than addressing the root cause, you are potentially making the original problem worse. I have found frequently that by normalizing length of the hamstrings, hip flexors and hip external rotation musculature rather pronounced leg length differences suddenly are minimal or eliminated.

Bike fit & cleat placement

Thank you for the detailed response last week. I just bought a set of Specialized Body Geometry shims and plan to start experimenting, given your suggestions. However, before I do I wanted to provide some additional information that occurred to me that might help you in your diagnosis.

First off, I mentioned previously that I currently wear a Specialized BG Pro Carbon shoe, which has built in to the sole 1.5mm of varus angulation. Might I need more?

Secondly, in years past when I used to run (before an ACL tear and reconstruction ended that—on my good side by the way) I noticed that on my left foot, the one in question, I was an inside “heel striker,” whereas on my right foot I was a more typical outside heel striker. Is this an indication of valgus angulation on the left and varus on the right—or is the running motion unrelated to cycling?

Before getting my Specialized shoes last year, I wore Shimano. I still wrestled with the same issue back then, but as mentioned earlier it seems more pronounced now. Maybe it is just mental, but then I thought, “what if the varus angulation of the shoe is exacerbating the condition because my foot is really valgus”?

One last thing:

I am very flexible now. I stretch aggressively almost daily. Further, I have been a serious weight trainer for 25 years. I have very good core strength; however, I do know that my dominant right side stabilizers are notably stronger.

Before I start experimenting, can you offer any more insight in light of the additional information above?

Steve Hogg replies:

I can give you a general picture but I can't diagnose what I can't see. I can make educated guesses as I do all the time but that isn't the same thing.Regarding whether you need further varus compensation - I don't know. Perhaps, perhaps not. That's why I suggested you visit a podiatrist or someone knowledgeable regarding feet and gait and find out what the situation is with regard to forefoot varus or valgus. Once you have done that you will have information, fact rather than guess work, that will allow me to advise you further based on hard information.

Interesting what you say about the difference in heel strike for each side. Typically, this means that there is either a leg length discrepancy (another box to tick) or a functional leg length difference caused by a lateral pelvic tilt. It can mean other things too, but they are the most likely. What it means too is that your gait isn't symmetrical. Gait plays a part in determining how we function neurally. If you gait is noticeably asymmetric, this will lead to functional asymmetries and in the end the motor control functions of your brain will be asymmetric as well.

Re the Specialized shoes seeming to make the condition worse. Yes, it may be that you have a valgus right forefoot. If that is the case, any shoe with varus compensation would make it worse. I can't stress enough that in an effort to solve your problem quickly, you need to be armed with information. It would be better to see a podiatrist or physiotherapist interested in feet so that you can find out what the story is with regard to your feet. This is infinitely better than trial and error until you eventually eliminate possibilities and stumble over the correct solution.

If you don't want to do that, try building up the outside edge of your shoe insole on your right side. If that improves things on left side, then it is likely that you have a right side valgus forefoot. If it makes the situation worse, or you get pain in the right hip or right knee after doing this, it is likely that you don't have a valgus right forefoot. The only thing that I can be nearly 100% certain of is that you function asymetrically with a tendency to favour the right side. This is the underlying general picture of the problem you have. What you need is more detailed information so that you know your own state of play and can make decisions based on what you find.

It is good that you are flexible and have good core strength. Both qualities will help minimise the effects of the asymmetric way you function in terms of pain or discomfort.
