lerouc Posted September 21, 2011 Posted September 21, 2011 Hi Don't know if this is the correct place to post this... I am very new to cycling and only started out 3 months ago. Went to a bike shop and bought myself a GT Avalanche 3.0 brand new and off I went. Now 3 months down the line I took the bike to a different bike shop as where I bought it to get a full on bike setup done. (as the shop that sold it to me just adjusted the seat a bit and off I went, so much for helping the new guys out) Now after doing the setup I need to get a new seat post as my seat needs to be moved more to the back and higher than the standard post can go. I asked the guy at the new shop but if I have to buy a new seat post doesn’t it actually mean that the bike I bought is actually too small for me and he said it could be. I did ask the guy that sold the bike to me what size I need to get and they still ordered me a large one as they didn’t have stock. Now I’m riding the large and I’m 1.85m tall, don’t know if that helps anyone. Also the reason I went for the setup was I am getting the worst pain in my neck from cycling and we came to the conclusion that it was a bike setup issue hence why I went for a proper setup and now all this. What am I to do? Should I just buy the new seat post and move on or will I develop further issues down the line (will this resolve the neck issue) because the bike isn’t actually the right size for me? Or is the bike the right size and the guy from the new shop is just taking a chance to sell a seat post my way? (highly doubt that) Must I go to the first shop and demand my money back as I think the CPA will back me up here as I did ask the shop I need a bike to fit me and I was literally there so they should know what size I need! If the frame is too small I wouldn’t demand a new bike or my money back I just want the correct size so I would settle for just a frame change and keep all my old components. In the end of the day I just don’t want to screw myself up because one guy didn’t know what he was doing when he sold the bike to me, if that is the case! Any help or advice would be greatly appreciated. Dankie,
AndreZA Posted September 21, 2011 Posted September 21, 2011 Frames should be measured using the top tube. S,M and L is a load of crock. I'm 1.88 and I will need anything from a 17" to a 20" (talking seat tube here) depending on brand while still maintaining more or less the same top tube.
pauloc Posted September 21, 2011 Posted September 21, 2011 I found the following site on the web that provides a table with recommended frame sizes for GT bikes. Based on your height, you may be between a L and XL, but the L shouldn't be too far off? I'm in the same predicament as you but between M and L and the medium fits me a lot better. Maybe try out an XL and see the difference?

DamMTBer Posted September 21, 2011 Posted September 21, 2011 Im 6 foot 1 so according to the hard tail chart im supposed to be a XL... Maybe, test the guys who you bought from first and ask for a bike setup and receipts with en all, and maybe they realise their on mistake.
pauloc Posted September 21, 2011 Posted September 21, 2011 Im 6 foot 1 so according to the hard tail chart im supposed to be a XL...You're actually 185 centimeters = 6 feet + 0.8 inches. Just under 6 foot 1

urbanroyal Posted September 21, 2011 Posted September 21, 2011 I am 1.74 and ride a Medium GT singlespeed ...no worries...
Witkop Posted September 21, 2011 Posted September 21, 2011 at over six foot, you should be looking at large to extra large. something over 21 inches. Also the bike assistant should have known that. I still cannot fathom bike shops, they simply sell what is on the floor. Go back and you six foot of persuassion to get the problem fixed.
mach7-7 Posted September 21, 2011 Posted September 21, 2011 I think you should go for an Ergo Fit Bike setup at Sport Science with Dr. Jeroen Swart. After taking your measurements he will inform you of your correct Effective Top Tube length. Remember that some manufacturers state top tube length while others state effective toptube length. If you are unsure of the two then I suggest you google it. I realise that this setup cannot always be done before purchasing a bicycle and I know it is not cheap but it will help you two fold: 1. You will find out what size of frame you should be riding. 2. You will be setup correctly with the correct saddle height, setback and handlebar drop thus correcting your neck pain and reducing the chances of further injuries that you may sustain as you start riding longer distances. There really is no substitute for comfort and your efficiency will increase straight away. Check out : http://www.sciencetosport.com/ or speak to hubber "renayg" as he also conducts the Ergo-Fit setup. I am not affiliated to this organisation and am not a salesman but merely a passionate cyclist that had plenty pain which has now be resolved after one of these setup's. Cycling is so much more enjoyable without the pain. Its definitely the best money that I have spent on myself let alone my bike
Schnavel Posted September 21, 2011 Posted September 21, 2011 You're actually 185 centimeters = 6 feet + 0.8 inches. Just under 6 foot 1 The frame size is not that important, as long as you can have a long enough seat post and stem that will allow for proper reach and leg height. According to the charts I should be on a L! I'm 181cm tall and I'm currently riding an 18" Medium Merida... I like the compact feel, I find it easier to control the smaller bike, and all I have is a longer seatpost... You just need to check the length of the top tube, it should be greater than 52cm or so
andydude Posted September 21, 2011 Posted September 21, 2011 You're actually 185 centimeters = 6 feet + 0.8 inches. Just under 6 foot 1 1 inch = +- 2.5cm 1 foot = 12 inches or 30cm therefore 185cm = 6 foot 2
lerouc Posted September 21, 2011 Author Posted September 21, 2011 well strictly speaking its 6 feet and 0.834645669291405 incheshttp://www.trueknowledge.com/q/1.85_meters_in_feet_and_inches
andydude Posted September 21, 2011 Posted September 21, 2011 well strictly speaking its 6 feet and 0.834645669291405 incheshttp://www.trueknowledge.com/q/1.85_meters_in_feet_and_inches Rounding added a bit of length! From Wikipedia: http://en.wikipedia.org/wiki/Inches "the international inch is defined as exactly 25.4 millimetres" or then 2.54cm and not 2.5cm as I've used. My bad.
