Here's a gallery of Planet X riders of all shapes and sizes with a few details of what worked for them. The bikes they ride are listed from extra small to extra large.
Rider: Patrick Brennan Team A3CRG
Inside Leg: 81cm
Frame Size: Stealth Pro Carbon650C X-SMALL.
Stem Length: 9cm
Comments: Love it. Really get over the bike and "feel as one with the machine".
Rider: Paul Curran
Height: 5â€²6â€³ (168cm)
Inside Leg: 30.5â€³ (77.5cm)
Weight: Mind yer own business
Frame Size: SL Pro Carbon Road SMALL
Stem Length: 13cm
Comments: I did contemplate a "medium" but Mark Lovatt said the "small" was my size. He was right, the top tube and head tube would have been too big on the med. I got myriding position no prob. on the small. Far too many gears on it though who needs 20 !!! Now when I was a lad...
Rider: Grip Smashstone (Stuntman and part time Ninja Warrior)
Height: 5â€²10â€³ (177cm)
Inside Leg: 32â€³ (81cm)
Frame Size: Stealth Alu SMALL
Stem Length: Never you mind, anyway it was cold in there
Comments: A small is perfect for getting low and tucked, with elbows at 90 degrees, so long as you can avoid hitting your knees on the pads
Rider: Hywel Davies (Px Team Rider - Triathlon and Time Trial)
Height: 5â€²9â€³ (175cm)
Inside Leg: 30â€³ (76.2cm)
Frame Size: Stealth Pro Carbon SMALL
Stem Length: 15cm
Comments: I seem to keep changing every year. I have experimented with a number of stems and saddle heights. A short or a downwards sloping stem is great for short TTs but prevents too much movement over a longer TT or Ironman. Saddle height is at: 71cm (top of saddle to centre of BB) and reach from end of saddle to handlebar is 54cm
Rider: Ric Gordon, Captain, Team Planet X Masters (USA)
Height: 5â€²8â€³ (173cm)
Inside Leg: 30â€³ (76cm)
Weight: 150 lbs (68kg)
Frame Size: Stealth Pro Carbon MEDIUM.
Stem Length: 100mm Adjustable positioned down the max 45 degrees, with no spacers.
Comments: Seat height is 100% of leg length to the top of the greater trochanter. Drop from saddle to top of arm rests is about 12cm. I like a longer top tube than most so went for the medium and used the adjustable stem to maintain a good drop from saddle to tri bars.
Rider: Sebastian Nurmela
Height: 5â€²8â€³ (171.5cm)
Inside Leg: 32inches (81cm)
Frame Size: SL Team Alu - MEDIUM
Stem Length: 130mm. 10 deg rise
Comments: I really like the long top tube and shorter head tube of the SL Team frame
Rider: Ian Cammish (PX team rider - Time Trial)
Height: 6ft 2ins (188cm)
Inside Leg: 34â€³ (86cm)
Weight: 13st (83kg)
Frame Size: Stealth Pro Carbon LARGE. Pro Carbon Track Frame (as in picture) MEDIUM
Stem Length: 13cm on both bikes
Comments: Feels great - tip - go for one size smaller on the track frame than on the Stealth (like I did!)
Rider: Paul Rothe - Triathlete
Height: 6â€²3â€³ (190.5cm)
Inside Leg: 34â€³ (86cm)
Frame Size: Stealth Pro Carbon X-LARGE
Stem Length: 11cm
Comments: Feels comfortable however I have flexibility issues in my lower few vertebrate (see "hump" in my back) which causes lower back pain. Currently tilting saddle a touch and finding that being more stretched out (plus some core work) is relieving this.
