Compact crank arm length

My road bike was built with a Campy Record group with a standard double crank which has served me well for the past five years. I'm looking at purchasing a compact crank because my knees are not getting any younger and I now live in a very hilly area. I'm 6'8" and my crank arm on my double is 180mm. Campy's maximum compact crank arm length is 175mm.

I've talked with many "fit experts" in bike shops and everyone has their opinion on correct crank arm length. Some say I need to stay with 180mm (which Campy doesn't make). Others say it's OK to go with the shorter length - 175mm. Some of these experts say I can mix a Shimano compact 180mm crank arm with my Campy group (heresy in my book). Others say it is not a good marriage. I've researched Specialties TA who make a crankset called the Carmina that has 180mm and 185mm crank arms. The bike shop that sells Specialties TA swears by them, but all of the "fit experts" either haven't heard of TA (which is surprising) or don't hold TA in high regard.

What are the physiological and performance issues that I will have to contend with if I drop down to the 175mm crank arm length? Or is the 175mm length too short and out of the question? I've been researching this for a long time and just when I think I've got the right answer someone else gives me their expert opinion and I'm back to square one again. Any advice/opinion/expertise on this issue would be greatly appreciated.

Bill Kraft

Bike fitting

Hello.

For all those cyclists considering the idea of a new bicycle for next season I'd like to pose a question to the bike fitters in the panel.

We all come in different shapes, sizes, and proportions, but most of us fall within a standard deviation or two. In your bike fitting experience, do you find that most bodies can achieve a reasonable position on a stock frame (as opposed to a custom job) from one of the many manufacturers? Are there certain areas that you are more concerned with (i.e. reach vs. seat-tube length)?

Bike shops can measure, fit, and recommend a frame to a cyclist, but I often wonder what constraints or motivations might come into play. What would you recommend to those who may not be able to shell out for a fully custom frame?

Thanks for your thoughts.

G'day Tyler,

Recovery from races

Hello, my name is Giancarlo Bianchi. I am a 23 yr old cat 3, 5'7" 134 lbs. While riding back from the morning ride today I was thinking about something that I knew I could count on you guys to answer.

Let's say you have to compete in two races in one day. Examples include a master competing in a 30+ and then the pro race later on, or a time trial in the morning or a RR, CRIT, etc. in the evening, a junior race in the morning and the cat 3,4,5 race later on, a track qualifying and the finals later, etc. I have two questions regarding this situation so I will number them for clarity.

1. How do you go about recovering for them? Obviously it depends on the time in between races but what should be the protocol? 24 oz carb drink if its 30 minutes or less? a bar if 30-60 mins? A sandwich? A meal? I imagine that there is probably a simple line graph that could be constructed...

2. Would you need to warm up for the second race? Again I see how it could depend on the time in between races, but what should be the protocol? If it's right after then no need, right? If its 30 minutes then a simple roll around would suffice?

This would be a great wealth of knowledge for everyone. Thanks in advance and hope to hear from you soon.

Hi Giancarlo,

Spin Scan analysis

I'm a 25 year old competitive cyclist. I see many bike-fit facilities offer a Spin Scan analysis to determine accurate seat height and pedal efficiency. Does it determine correct cleat position as well? I would like to know if the spin scan analysis is really worth a try, or is it a waste of time.

Thank You!

Hello Juan,

Posterior knee problems

Hi. I'm a 24 year old, keen, competitive mountain biker riding for around five years now; however I ramped up my training and was beginning to compete in races last year to gain my fourth category road racing licence. After a break in September 2006, l started to train for the following season however had to stop when l injured my left soleus and posterior part of my left knee. I had noticed a slight weakness in the knee approximately a year previous to the injury, but after some rest the pain disappeared. The pain came on in a ride where l was pushing on into the wind, and I admit, pushing too big a gear.

Much to my downfall, I decided to keep riding. The pain persisted, and so I began to seek treatment through physiotherapy, without much success. Unfortunately the trouble persists to this day, almost a year later. Due to various commitments I have been unable to stay with a single physiotherapist, and as a result I have only recently received a diagnosis that I have flat feet. I have been fitted with orthotics which seems to have cured the pain I was getting in my soleus muscles. The sharp pain in my knee is now in two distinct areas, either side of the centre of the knee as seen from the back. The pain occurs during walking as well as cycling, and so affects my day to day activities. My current physio believes the issue is being exacerbated due to my knees, which are able to hyperextend when walking. This has caused the posterior capsule to become lax, and the popliteus tendon and ligament to strain.

I am awaiting the results of an MRI scan on my knee, however am now at the end of my tether due to not being able to ride consistently over the past year, and not at all over the past month following advice to rest.

Dropping my seat height by around half an inch, and moving it forward, together with has helped, but do you have any other specific advice that may enable me to get back riding? I am worried that an injury that has persisted for this long will not heal at all, and my riding days will be over.

If it helps, I ride a Cannondale R1000, 56cm (c to c) frame, 90mm stem, with a BB to seat height of 730mm (after dropping the seat). My inside leg is 79cm, and I am 1.76m.

G'day Dyfan,

Hypertrophic cardiomyopathy risk for cyclists?

I am a 47 year old male recreational road cyclist, typically riding 4-5000 kilometres a year. I ride regularly with a group of friends, ranging in age from 36 to 60. After the recent and well publicized death of runner Ryan Shay in the New York City Marathon, speculation has risen that the cause of death was hypertrophic cardiomyopathy (enlarged heart). Then last week, a friend of mine who is a strong marathon runner (sub 3 hr) lost consciousness after a 1K jog from the car to the start line of a local marathon. He suffered a concussion from falling, but doctors are at a loss as to why he passed out. Early suspicion is that he may have hypertrophic cardiomyopathy. With all the talk of this condition and sudden death in endurance athletes, our spouses have voiced concern that we may be putting ourselves at risk.

My question is does hypertrophic cardiomyopathy present a serious risk to cyclists? It seems to me that the majority of cases of sudden death involve runners. Is there something inherent in running to exasperate this condition, or is it just that so many people run compared to other endurance sports?

Thanks,
Ira Birt

Scott Safier replies:

The media did a terrible job of covering the death of Ryan Shay. Hypertrophic cardiomyopathy (HCM) is a genetic disease. You cannot get it by exercising. Individuals with HCM have a mutated gene for one of the contractile proteins in their heart muscle. Because of the mutation, the muscle does not contract as well as it should. As a result, the muscle grows in an attempt to handle the load it is required to handle. The enlarged heart in HCM has a thickened wall and reduced stroke volume because the muscle actually gets so big that it takes up what should be the pump chamber of the heart. There are many different mutations that lead to HCM. Some of them make the muscle so inefficient that it grows so quickly that individuals with that mutation all die in the childhood. Some of the mutations work more slowly and cause deaths later. Some are relatively benign, leading to a slightly thickened heart wall but rarely death.

New bike fit

My team is getting new road bikes for next season, and I need to figure out which size frame suits my needs best. I am a 31 year old, male racer, and have been riding for about 2 years. I race both criteriums and road races, with a slight emphasis on criteriums.

I have been professionally fit on my current Fuji bike. It is a size 58 (seat tube, C-T), with a 57 cm top tube (C-C). The seat tube angle is 73 and the head tube angle is 73.5. I have it fitted with a 100 mm stem, making the effective reach 670 mm.

The new bikes will be Ridley's. Both the size M and L, fitted with different stems and seat post lengths will give me the needed dimensions, but both have their advantages / disadvantages.

The size M has a 560 mm effective top tube length (with a seat tube angle of 73 degrees), so fitted with a 110 mm stem will give me the correct reach. But the seat tube is only 540 mm (C-T), which would require 225 mm of seat post for my saddle height of 765 mm. The head tube is also only 175 mm, which would require 40 mm of spacers below the stem to raise the handlebars as high as I require.

The size L has a 585 mm effective top tube length (with a slacker seat tube angle of 72.5 degrees), so fitted with a 90 mm stem will give me approximately the same reach. It would require 195 mm of seat post and the head tube is 205 mm, which would only require 10 mm of spacers under the stem.

My questions are what is preferable: a longer top tube with a short stem, or a longer stem with more spacers on the steer tube? I have heard that shorter stems can affect the way the bike handles, and that additional steer tube length can affect the stiffness of the front end, and thereby affect handling as well.

Thanks,
Matthew Triska

Steve Hogg replies:

G'day Matthew,

Matthew responded:

Steve,

The head tube length on my existing bike is 169 mm, and the new bikes are: size M - 175 mm; size L - 205 mm. I am using the stem flipped to the higher position. I have relatively poor flexibility, which is why the need for a shorter reach and high bars.

Thanks,
Matthew Triska
