Round EGGrings
The chainring arrived yesterday. One of the others you supplied is still going after more than 40,000 km. Many thanks.

The chainring is quality, it's like riding a different machine. Thanks for making it.
(PD, UK, 2010)
Thank you for having made such a brilliant chainring - the only one I've ever used which didn't lose the chain, ever!
(Paul, UK, 2009)
I remember being MOST impressed with your chainrings which we used on the two Greenspeeds which were ridden 15,000 kms around Oz about 1993. We used your 62t rings as the main ring and 42 t Shimano rings as the low ring. The riders found that while most cyclists needed to change their transmissions 1/2 way round, theirs lasted the full distance. Furthermore we found that while the 42t ring was used only about 10% of the time, it and the chain were worn out, while the main 62t Egg ring was as good as new!

I have your chainrings on 2 of my Moultons (an oval on the AM7) and they last almost forever !!
(Robert Spence, UK, 2007)
I can't thank you enough for an incredible job! These rings are superlative!! I have shared them with a few framebuilders who are drooling. I can't say enough about how gorgeous your work is. You continue to fulfill the role of God's personal chainring maker.

I have one Highpath chainring - on my Mountain Drive equipped upright Brompton. This was the 3rd chainring I've put on - the first two did not last for long at all (300 miles and 1,750 miles) as they developed sideways distortions. My Highpath chainring has lasted 5,500 miles and shows little sign of wear and is still true.

I've just gone through the once-every-two-year drivetrain replacement on my Greenspeed commuting trike. This machine clocks up around 3000 miles/year, is commuting in all weathers (damp UK winters) and spends its days parked outside. I'm afraid that I don't look after it as well as I should. Yet again, a brand new chain and cassette goes on and still the 10 year old chainring you made for me is again a perfect snug fit - no sign of wear at all! Thanks for a great piece of kit!
(Rob Hague, UK, 2007)
The chainrings were great for my first TT with them. PB for the course and took time out of all my benchmark competitors.

Oval EGGrings
I'm back from my first bike trip with the new chainwheel and it works and look gorgeous. Here are some pictures. I just had to place a message in the Birdy-bike-forum to rave about your piece of art...
(TLG, Germany, 2009)
I've finally had a chance to ride in anger a pair of the Egg Rings you made for me (50t 11% and 36t 15% on a Pinarello Paris) and have to say I'm amazed! I've been riding with Rotor Q-Rings for nearly two years so it wasn't just the ovalisation that made a difference. A few months ago, I would've scoffed at the suggestion that it was possible to feel a difference in quality between different chainrings, but now I know it's true. With the Q-Rings, shifting was always a little 'finicky' but your rings shift like a dream! The feeling is hard to describe but they're stiffer and the power transfer through the chain feels smoother and more direct. Thanks for your advice and for producing such wonderful chainrings!

I've been using Chris Bell's oval chainrings [on my Greenspeed recumbent] for many years. I find that having a greater ovality in the small rings is very useful for hill climbing where there is limited traction. The net result is easier and smoother hill climbing.
(Ian Sims, Australia, 2006)
I have just come back from an hour ride with the Ovals installed. The system comprises 170mm cranks with a round 52t ring, a 42t middle ring with 10% ovality, and a inner ring of 30t with 20% ovality. The oval chainrings replaced round chainrings with the same tooth number. Crank length is also identical and I swapped my old pedals over.
Oh boy, are these oval rings good or what!!
On one long hill, I get so exhausted that I stop 3 times - all within the last 200 metres or so. Tonight, with the oval chainrings fitted, I DID NOT STOP ON THE HILL AT ALL!! I find that quite incredible. No other change but the different shaped chainrings.
The other thing that surprised me is that the oval chainrings feel quite 'natural'. In fact, if anything, they give the legs a more fluid reciprocating feel. Watching the chainwheel circumference going up and down is weird, but the leg movement feels fine.
(Julian Edgar, Australia, Dec 2006)
I can remember going around looking for hills to climb when I first got the EGGrings - just an amazing smooth, powerful feel. Now I do rather take them for granted - I just cruise along and the climb disappears. For me there is no comparison - I've got more energy for the cycling, and I'm having a heap more fun.

Pulse Crank Shorteners
Just wanted to say thank you so much for the crank shortener. I can't believe none of my surgeons/doctors know about this - I hadn't ridden a bike since I was 13 (9 years ago) and my doctors always told me that I never would after knee surgery, so I'll definitely be telling them about this (then they can stop telling any other patients that their chances of cycling again are zero!).
(Rand Mikael, UK, 2011)
Today I try your crank shortener. I am very happy!!!! Is the solution for my problem. Thank you very much.
(ST, Italy, 2009)
Fitted the crank shortener at the weekend and tried it with a 2.5 mile ride - the first time I have cycled since my knee operation four months ago. It worked fine and I am looking forward to transferring it to the new bike I have ordered today - safe in the knowledge that I can resume cycling. Thanks once again.

Pulse Swing Cranks
All fits perfectly and I have done some pedalling on a proper bike. It feels great. Many thanks for your helpful service and a very nice piece of engineering.
(TM, UK, 2010)
I purchased a Swing Crank from you and then went on a holiday to France. Camped and cycled on towpaths. Amazing, as my rugby knee injury prevented me from such activity. You have given me a new life - one I thought I had lost. Now a stone lighter and getting back my fitness levels. Thank you again.
(JR, UK, 2009)
After 5 months of finding cycling impossible after knee replacement, I am now back on my beloved bike thanks to the Swing Crank. Very many thanks for your prompt service (and ingenuity). I have passed details of your excellent service to the Physiotherapy Dept of the hospital that I attend, as I feel others will benefit from this excellent piece of engineering. Many thanks once again.

Pulse Pedal Extenders
The Pedal Extensions you sent me are great. Previously, the bike made my knee joints hurt to the point that it was no longer a pleasure to ride, and my calves were striking the crank with every rotation of the pedals; they are now well clear.

Crank Repairs
I just wanted to say what a great job you made of my shortened crank. Really high quality work! I'm very pleased with it.
(PM, UK, 2010)
Only just had a chance to test your repaired crank arm yesterday. It's perfect. Thanks again. You're now highly recommeded by me to my friends/colleagues.
