Well you've got a few choices here Jack. Hargroves in Fareham do the BG Fit from Specialized. This is based on the Andy Pruitt method that he developed with American frame maker Serotta (makers of beautiful frames but very expensive). Here they'll set up your saddle height using a tool called a goniometre which gives you the angle your knee is at at the bottom stroke which according to this model of set up should be between 25 - 35 degress. They also set up your plum line and your cleats. Price last time of asking was £120.00. The Saxo Bank team all had it done and they said that it improved performance greatly, but they would.

Rock'n'Road in Bitterne will also do a fit session which again is based on the Serotta model but the guy there will watch you pedal for about 2 hours and then adjust your position. That doesn't sound to technical but James, the guy there, has been doing it for years and knows his stuff. Last price was around £175. He will spend a good 3 - 4 hours getting you set up right.

Now to save you some money I've got a goniometre you can have a lend of and if you check out the link you'll be able to see the best angle for pedalling and with the help of a friend, who knows about angles, you could get your saddle at the right height.

You might want to invest in The complete medical guide for cyclist at Amazon by Andy Pruitt. I think you'll find it really helpful. It's got everything from bike fit to recovery. If you haven't already got it that is.

Hope this helps in some way and i'm planning to be out on a ride with you soon.

Cheers. Carl

Hi

Carl's is spot on with his comments, Andy Pruitt's book is a good read especially if you like Specialized, his approach is very much common sense based and emphasizes comfort. I would suggest it would be a sound investment even if you decide to pay for a professional fit.

I did some work with James from Specialized who teaches all of their BG fitters in the UK and watched him do a number of fits for the RYA who have a deal with them for their Olympic squad who do quite a lot of cycling as it's good low impact aerobic training (they are based at Weymouth so very good at hills, check out the contour lines). Interestingly, James fitted the Saxo bank team last year and most went Spesh's widest saddle.

From observations it isn't rocket science, we have done some fitting at work using motion analysis software designed for dynamic fitting (based on Pruitt's guidelines), which seem pretty good so there might be an opportunity for some free fitting if your prepared to be a guinea pig some time in the New Year, I will post a call for volunteers if needed.

However, what you often get from a shop fitting service is the opportunity to swap around components (mostly stems length angles etc., but also seat posts with various set-back), the BG system also looks at inserting shims in shoes to correct excessive knee movement etc., when necessary.

Often knee problems stem from the foot up so it is worth checking your cleats are properly set-up and perhaps switching to a pedal type which gives you more float, I moved to Speedplays because of knee problems and it seems to have done the trick, albeit at a price (£££).

Perhaps the basics of bike fitting could be included as one of the winter workshops proposed at the AGM.

I cant see the problem with the pedals as i've used the same designed shimano ones,i will keep the bike fitting contacts in mind if i cant get this sorted after christmas,
