Re: Two-bolt seatpost designs

Although accessing the bolt heads may be a problem with the Campagnolo posts, the design has the advantage that the pivot for the lower jaw has a small radius. I haven’t managed to find photos of a disassembled Nitto, but I imagine the semi-cylindrical trough in which the lower clamp rests has a la...

Re: Two-bolt seatpost designs

I note that those three downsides of the Deda would not be present with the Nitto S83. Yes! I was almost going to add that having rotating collars in the top clamps rather than at the bottom would give the best of both and it looks like that's exactly what they've done. It does cost two or three ti...

Re: Two-bolt seatpost designs

I have a Deda Elementi RS01 seatpost that works in a similar way. Adjustment is done with allen keys from beneath. http://bestbiking.nl/content/images/thumbs/0000260_deda-rs-01-zadelpen.jpeg Instead of the screws threading into rotating collars, the top clamp angle is kept the same but they are roun...

Re: Mini-Track-pumps: why none extended to normal height (and any DIY mods?)

Thinking outside the box: if you don't like kneeling down then maybe carrying a small piece of camping mat to kneel on would make it more pleasant and would be lighter and more robust than a long extension.

Re: Pedal washers

Why not just buy a baggie of 14mm washers off ebay for about £1.50 posted?

Re: Grease is the word; a complicated word...

Fantastic thread! You say you use Finish Line grease and I see that they do a ceramic version too. They also make ceramic chain lube. "Ceramic" obviously covers a lot of different materials but I'm not sure why you would want any in there. Do you think this is just marketing guff or is is ...

Re: You Tube Head Cam footage

In 2015 TFL found that roughly 1 in 500,000 journeys by bicycle in London resulted in death or serious injury. It therefore seems likely that if head-cammers uploaded all of their footage you would never be able to find the incidents buried under all the uneventful journeys. It's just that with 23 m...

Re: Natural clothing

Is anyone familiar with the current state of waterproof fabrics? I was a few years ago but I lost touch. They were about to ban the chemical(s) that were used for the DWR in every commercial garment at the time due to environmental concerns. Clothing manufacturers were set to switch to an alternativ...

Re: Natural clothing

I suspect people's differing perceptions of the same fabrics comes down to how much they sweat. Cotton is slow to dry but it absorbs sweat beautifully. If you aren't sweating much then a thick cotton t-shirt keeps you dry for quite a long time and feels great. If you are sweating a lot it is quickly...

If you are looking for information on the whole rinko thing you should look at Jan Heine's blog https://janheine.wordpress.com/ I've been around the centre of Japan ~Tokyo, Niigata, Toyama, Nagoya but on a small motorbike, not a bicycle. Some large areas of Japan are pancake flat and pretty much cov...

Re: String Bikes

I'd be concerned about torque on the drums, and string-stretch losses. Looks like it's nylon cord .......... and as it's nylon cord, it's springy. I would be astonished if it wasn't some kind of dyneema cord. Dyneema is extremely strong and inelastic. I was looking at some the other day: 2mm diamet...

Re: String Bikes

I always thought the string bikes looked really cool. It doesn't sound like the strings last too long but I reckon you could buy your own dyneema spool from a sailing supplier and crimp the ends yourself for bulk savings. It looks like string changing is quick, easy and tool-less, and they won't wei...

Re: Premium rush?

It falls firmly into the "so bad it's good" category in my book. My favorite bit is when Dania Ramirez crashes due to her use of those dangerous and unnecessary brakes (uh-huh). She gets up and, in frustration, casually rips off her front brake - the lever, caliper and cable all together -...

Re: Anti pollution masks - waste of money?

I do think those respro masks are probably useless. The filters are too small and I can't see them sealing well enough to your face. I've said it before but if someone really wants to use a respirator I'd recommend a 3M 7500. It'll seal to your face properly, have proper filters and will minimise re...
