Happy birthday Andrew Thanks for all the wonderful tandem tips. You are a inspiration for many cyclists out there. Thanks db

Hey so my Trek will gain some attention again! yes!

From their site: The most often asked question about Q-Rings is "how are these different from the Shimano Bio-Pace and other brands of non-circular chainrings?" The short and simple but not so obvious answers are: * The Q-Rings are elliptical; the Bio-pace and O.SYMETRIC chainrings are asymmetrical. The specific elliptical shape of the Q's provide a very smooth uniform pedaling stroke; there is no sudden acceleration movement. * The Bio-Pace chainrings are designed so the maximum equivalent tooth size is at the dead-spots. The Q's have the minimum equivalent tooth size at the dead-spots. This enables you to pass through the dead-spots quicker with less stress to your knees. * The Q-Rings take into consideration the forces from your legs in static conditions and the inertias of the cyclist and the bicycle. This maximizes the efficiency and comfort of conventional cranks. * The ROTOR patented OCP system enables you to customize the position of the Q-Rings to suit your individual riding habits, body geometry, strength and position on the bike.

The concept behind Q-Rings enables you to push an effective bigger gear while in the power down stroke when your leg muscles are able to apply more power and an effective smaller gear while in the dead-spots; while producing a smooth pedaling motion. Riders report that "it is like dancing up the hill."

Dont even go there - the last time this was debated with technical views and points the topic hit 30 odd pages and we almost had lawsuits................ OK ... then I'm out..... seen those threads and don't like them Just trying to give my thoughts on Q-rings.... amazing what they do.... even if one cant explain it. We who know should actually not comment and just enjoy our new ride.... and new times.. and..... Decibach2008-07-24 05:19:19

So what you really mean is that you and the stoker were not getting out the saddle in unison? You felt a disruption in rhythm caused by the two of you acting in a slightly un-cordinated fashion' date=' now, through more experience together, or whatever, you are more in sync, and you want to justify the cash you unloaded on the biopace chanrings? Ok, cool, whatever, but see it for what it is... [/quote'] Sorry TNT1 said it wrong... my stoker and I know each other well.. I meant each time we started to climb a hill....

I would really like Johan's comments. It would be good to get a technical opinion. But... one things for certain... they make a huge difference for my stoker and I. I have never in my years of cycling came across a component that made such a big difference on our tandem... worth every cent...

Oh ja.... HAppy Birthday!!

Cant explain it but will try... When my stoker and I started climbing... it was as if hhis powerstroke came in just after mine. It felt as if I hit a brick wall and then he came and chipped on the wall himself. Somehow the Q rings smoothed/broadend that powerstroke. Now when I come in with my Powerstroke it's as if his stroke more evenly comes together with mine and then we have like a 10 pound hammer effect against the climb. Our stroke now feels elastic... compensating for the uneven power strokes... anyway... must feel it to believe it...

Cant believe the double up guys dont make use of them.... I am so exited to do all the races again with the q-rings. We are for sure going to take 20-30min off our times on a avg 100km race. Glad for you Backlash... it's rewarding to have a new component make such a big difference. Even on the flats and downhills.... such a smooth stroke...

Le Turbo 501 Reynoldts frame Ice Blue my first bike R1200 1987, besides for my Western Flyer Bomber. The Alpina's bright colours I remember from Beneke Cycles (mark and gary) in the south of JHB. I also remember the BMX era was huge... those chrome Mangooses was big then - 1983/4 I rode an Invader red and chrome. Vitus was one of the top bikes then. The frames I remember was Reynoldt 501/525/535/701 Cycling shops in the south was Beneke/Rauti Krog? / Advance Cycles.... aai the good old days....

Just seen his interview... shaim man.. seem like a very nice guy. You can see he feels stupid about it... He is acrualy very lucky.. that is very steap.

Hi Don't know who loves there Rugby that much.... But there is this online prediction game called Superbru, where you can predict different Rugby games in the Currie Cup and Tri Nations. They now going to have a prediction game called Superbru Tour de France. What's nice about it is that by taking part in the predictions, you also are being kept up to date with the latest outcomes and leaders etc. I've created a pool where most hubbers can join: (POOL CODE :deedcent) ... but you guys/girls can create your own pool as well. You can play up to 3 pools. Should be interesting. Check it out on Superbru Tour de France Cheers db Decibach2008-06-30 06:36:03

Also at Sportmanswarehouse .....R99-00 accent?

that's great will join them to... for there is nobody in DELMAS

I am always worried about those straps.... but nothing wrong so far. you must make sure not to cut them to close to the hook point..

I bought a trek 2000 SLR9000 frame, carbon fork and carbon rear stay's with complete Shimano 105 Groupset for R7300-00 brand new at Cyclelab. Last years stock..... I cant think that I could have done better with my money somewhere else.
