Re: 'zero reach' stem for 1.1/8 steerer

... I believe that 559 wheels are much better for smaller people. My wife of 5.2" even has a beautiful Roberts.. Not "much" better. Maybe a bit better, depending on the rest of the design. For example, if you stick with the 72 degree head angle common in 700c Audax type bikes, becaus...

Re: 'zero reach' stem for 1.1/8 steerer

Correct me if I'm wrong. If a dropped 'bar bike had zero reach, would it handle correctly? With the stem pointing forwards it gives stability as your hands would be forward of the steerer. Could you in theory put the stem on backwards and there would be zero effect? Somehow I think not. Or am I wro...

Re: 'zero reach' stem for 1.1/8 steerer

I always post this in the hope that someone will either prove me conclusively wrong (I'm open to correction) or second my opinion: There is no such thing as a women's specific design, contrary to Specialized's claims. A short top tube simply brings the saddle forward which then has to be put back, ...

Re: Relative weights of Spa touring and Audax bikes with and without discs

Why are we looking at an E bay advertisement for a Spa bike? Do we all mean the same thing by "inside leg"? I take a 31" trouser, so crotch to floor is approaching 34". Its maybe 10 years ago, but I think this photo of a 54 Spa Tourer is set up for me.. https://www.spacycles.co.u...

Re: Plagued by tight glutes and tight lower back muscles

531 makes some valid points but don't get too depressed, in my mid 50's i'm riding further and faster than I did at 40 and my head still thinks i'm 30 (who'd want to be 20 again? I was a crap if enthusiastic rider back then! :lol: ) Indeed I used to be in a state after 50 miles but I rarely do less...

Re: Relative weights of Spa touring and Audax bikes with and without discs

While we’re on tubing, do the 54 cm and 58 cm Spa Audax rim-braked models use the same tubing? I ask because I just got a 58 cm and it weighs around 250 g more than my 54 cm, which is slightly more than I expected … but I hadn’t given much thought to weight differences across frame sizes. Spa added...

Re: Relative weights of Spa touring and Audax bikes with and without discs

Just back from fantastic ride on my Spa audax, thanks Colin! The brakes just about held me on the descent int Dentdale from Kingsdale, they are of course side pull not cantis as I mentioned by mistake above. Just wanted to say what a great ride this is. Thats a proper descent, that is. Its OK if yo...

Re: Plagued by tight glutes and tight lower back muscles

Heres how it works. As we get older, our body changes....OK, it deteriorates. When you push down on the pedal, the "equal and opposite reaction" of Newtonian physics supports your torso, which is cantilevered out in front of the saddle. As you get older, you can't pedal so hard, or so hard...
