Litespeed Vortex Dura Ace 9 Speed

Advantages: Top of the range "bling" rear mech
Disadvantages: 9 speed "only", superceeded by RD-7800 10-speed version

...I bought this rear derailleur to replace an Ultegra mech when upgrading my bike from 8 to 9-speeds (well, 16 to 18 speed really with my double front chainset). Apparently, this mech is also compatible with 8-speed systems, you just need to change the cable mounting position. Dura Ace is the name of Shimano's top of the range group of bicycle components, or "groupset", for road race bikes, and the 9-speed 7700-series was introduced to the public in 1997 after Shimano sponsored riders using Dura-Ace 7700 series equipped bikes in 1996. Year by year, it's been enhanced, and this review is of rear mech from the 2004 model year. For the non-bike-ophiles among you, the rear mech (or mechanism) is the device at the back end of the bike that moves the chain across the muliple cogs (cassette) on the back wheel to change gear - bigger cog...

Advantages: Best fins i have ever used
Disadvantages: Very plain looking, everyone has them

Well the answer is better than you can if you don't have a split in your fins. The Oceanic Vortex V12 fins make moving through the water allot easier than with normal fins because for some reason you use less energy and travel faster too (I have no idea how this works it just does lol, take my word for it) I got my fins from my local dive shop for £80 because I was sick of my old Cressi fins Looks: The Vortex V12's come in one colour, black so they look pretty plain, which...

Advantages: strong
Disadvantages: expensive

...Being a keen biker i have to recomend this chain ring for all those bikers that ride Dual, Downhill and Dirt riding. This ring will offer speed at a price though. I personally ride dirt and dual and Shimano make superb Quality product. However this chain ring is mass produced and so it lacks the personalized touch that other manufacturers give to their chain rings. I would recomend this as my second choice chain ring as i feel the Middle burn rings are slightly better. All in all a poor buy. I do not recomend this product.... Read review
