We at Veloscope love cycling; exactly the reason why we contacted Bjorn (Cycle Precision)personally and found out the details of his second bike fitting session at Spectrum Physio Centre in first week of July 2013; We want our friends shouldn’t miss out this opportunity; especially when we know that a lot of us ride wrongly fitted bike! Here is a detailed mail from Bjorn : “Dear riders, It’s already a few months since we organised a bike fitting week in Bangalore in association with Spectrum Physio. After the many positive feedback we received we are now organising another bike fitting event in Bangalore. The bike fitting sessions will take place on Monday 1st July, Tuesday 2nd July and from Monday 8th July to Friday 12th July at the Sita Bhateja Speciality Hospital. We will have 3 sessions every day, each lasting around 2 and a half hours in which we will cover foot analysis and cleat set up, flexibility and bike set up. At the end of the session we will give you a detailed report with all our findings and recommendations. More details below.
A good bikefit will not only prevent injury or discomfort but will also ensure optimal efficiency. When we perform a bikefit for someone we have 3 primary goals. Each of these will be taken into account during the bikefitting but the importance of each will depend on the events the rider concentrates on. E.g. for an endurance rider who spends several hours on the bike comfort will be important whereas for a 10 mile time triallist who only spends 20 minutes on the bike efficiency will be the main goal.
Pedaling on a bike is a repetitive action which means that even small issues can lead to discomfort or injury over time. A good bikefit will in the first instance minimise the chance of discomfort or injury. Small discomfort is likely to lead to injury in time when not addressed. Imagine rubbing a soft cloth over a surface. Will this cause damage? probably not. But now imagine rubbing that same cloth over the same bit of surface 20000 times (the average number of pedal strokes in a 4 hour ride). Will there be any damage? Most likely some wear will develop. This is basically what happens when cycling. A small issue can over time develop in either discomfort or if not remedied into injury. But what will discomfort guarantee is a loss in performance and efficiency.
As we all try to save energy in daily life, so we should not be wasting energy when cycling. A good bikefit will ensure maximum performance, allowing you to get the most out of every pedal stroke. Imagine the knee doesn’t track in a straight line but moves outwards 5cm and back on every pedal stroke. This means that the knee travels laterally 10cm (out and back in) every pedal stroke. At a cadence of 90rpm this means the knee travels 900cm every minute unnecesarily. Over a 4 hour ride the knee will have traveled 216000cm or an extra 2.1kkm! Apart from not being able to produce maximal power it means energy was wasted for the knee to cover the extra 2.1 km. Efficiency also takes into account looking at the aero position. The best position is not necessarily the most aero position but the position that allows you to ride the fastest. What is important here is to ride in a position that is sustainable. If the position cannot be sustained and the rider needs to adjust his/her position continuously then the airflow will be disturbed resulting in a loss of efficiency and speed.
The position on the bike should allow for a clear view and should allow the rider to safely reach for a bottle or energy gel out of his/her back pocket.
Bike fitting service
In association with Spectrum Physio we will be offering a full bike fitting service. Spectrum Physio who will be able to advise on all musco-skeletal related issues and will be able to advise on recovering from injuries, therapy and exercises that can improve your cycling.
Foot analysis and cleat set up
The foot/pedal interface is the most important aspect of the whole bike fit. Any instability in the foot/pedal interface will travel along the bio-mechanical chain to the knee and hips. At a minimum this will result in a loss in pedal efficiency but can also lead to discomfort (knee or hip pain) in many cases and in the worst case it can lead to injury when not addressed.
During the foot analysis we examine the forefoot varus or valgus tilt and analyse the effect of weight bearing on the arch. As most people benefit from special support innnersoles a pair of semi custom insoles (eSoles) will be included as part of the bikefit.
Taking into account the foot analysis the eSoles will be configured, the cleats set up in the correct location and wedges and/or stacks which will either be fitted underneath the cleats or inside the shoe to fully stabilise the foot on the pedal.
As a final step in the cleat set up we will check the pedal stroke on the bike to ensure the knee is tracking in a straight line. Markers will be placed on key anatomical landmarks and highlighted with a laser to evaluate the tracking of the knee.
Flexibility assessment and bike set up
In order to set up the bike we will take into account the riders cycling goals and past experience. After a short warm up we will assess the riders flexibility as flexibility has a great influence on the final riding position.
Based on your cycling goals the saddle and handlebars are set up in the correct position. If necessary you can try different saddles to ensure you sit stable on the saddle without any hip movement as this will result in discomfort and loss of efficiency. We will also be in a position to let you try different size handlebars with different stem sizes (using a fully adjustable stem) to let you experience the difference and tune the bike to your ideal position.
Further recommendations are given on changes that might be required to achieve the ideal riding position. We will also observe pedal stroke and general rider position on the bike and make recommendations accordingly.
At the end of the bikefitting the rider will be given a detailed report including the changes to the bike set up and recommendations as to how to achieve the ideal bike fit (handle bar width, stem …) as well as recommendations on pedal technique and flexibility.
The price for a full bike fit will be Rs. 12,000 including one pair of eSoles. Alternatively we can offer a fitting without the eSoles for Rs. 9,000. However from our experience most people benefit from the eSoles. Please get in touch if you would like to book your bike fit or if you have any questions and I will do my best to answer all your queries.
I hope to see many of you soon either for a bike fitting or maybe I can join you on one of your bike rides.
