...or how I found "the best suspension seatpost ever made in the history of the world" and some other stuff.

:D

This thread - http://forums.mtbr.com/showthread.php?t=659155&highlight=suntour+seatpost

So in my quest to further geek out my commuter, I started researching suspension. I know, I know, suspension on a road bike. Anyway, this seatpost has worked it's way into top five favorite commuting gadgets for my bike.

SR Suntour SP8-NCX ~$80

Preload adjustable via an allen key in the bottom of the seatpost.
50mm travel.
Available in 27.2 and 26.8
Weighs a ton (I'll try to get a weight this week)

I have my set up so that it only activates when I hit a bump. No pedal bob or wiggle in the linkage. It takes out all the road chatter that usually gets transmitted to my bottom. I found myself looking for bumps and seams to run over just to try. I do wish it had rebound dampening, but it's not a big deal unless I hit something HUGE.

It looks pretty interresting. Do you still have room for a tube/tool bag?
Hey, nice headlight BTW!
hahahah, thanks. You have a nice headlight, too. :thumbsup:

hmm... I'm not sure I would run a bag on this post unless it was one of those that only attached to the seat rails and not the post.

Michelin Protek Max inner tubes

https://www.bikeradar.com/news/arti...d-racer-tire-and-protek-max-inner-tube-29696/



Michelin also showed off their new Protek Max inner tubes, which use a uniquely bumpy surface and square-shaped cross section that's claimed to be much more resistant to punctures - or more specifically, losing air pressure due to punctures - than standard inner tubes. According to Megavand, the Protek Max's bumpy surface creates a compressive force in the tube wall, in contrast to standard inner tubes where the tube walls are stretched upon inflation.

This means that small punctures which would typically enlarge with conventional stretched tubes instead tend to self-seal. In addition, the curious square cross-sectional shape is said to ease installation by maintaining the correct orientation when inserted into the tire. Michelin still equip each Protek Max tube with some sealant to finish the job, and they claim a two-fold improvement in air retention relative to other pre-sealed tubes.

The Protek Max tubes will be offered with either Presta or Schrader valves in two sizes: 700x35-47c (200g) and 26x1.4-2.125in (260g). Suggested retail price is a surprisingly reasonable $8.99.
Looks interesting from a commuting aspect, though I haven't had a flat in years.

No rattle at all.

Works GREAT with loaded panniers.

Front wheel does raise when loaded, but if you cut the kickstand down, you could theoretically get it really low.

LOVE the seatpost. Took a while to get it dialed, but it's perfect now. Takes the edge off and doesn't effect pedaling at all.

The spring is just to keep the wheel from swinging around when it is up in the air. Doesn't do anything to stabilize. It is too weak of a spring.

A'me heated bar tape. Oh my dear Lord. Sign me up.

Edit: and Stemcaptain makes a thermometer version!! I need one! That and heated bar tape and I'd be ready for winter.

I`d go for the clock on the cap thing if I didn`t have quill stems on my bikes. The first one I saw was in the pictures of your commuters thread this spring- sweet!

Ryball, it seems to me you were doing serious research into short travel road bike suspension forks. I don`t suppose you ever found anything still actually available along those lines, did you? I`m surprised that hasn`t developed into a thriving little niche.

As a matter of fact, I did. :D

There are a lot of short travel forks that are made for city bikes. They all weighed a ton.

There are two that were lighter.

RST Single Shock M7-T - RST

SR Suntour Swingschock - SR SUNTOUR Cycling

The press for the suntour initially hinted at a fender that never materialized. So to retain fender mounts and light weight it came down to the RST. The best place to find these are on fleabay.

I eventually gave up on the idea because I wanted something with clearance for larger tires and could never get a confirmation on what size would fit with fenders.

Maybe one day I'll pick the idea back up again.

The RST you linked looks like only 950g for the lightest version- not bad at all, IMO. They look fairly nice, too. But they say disc brake or canti, with no mention of sidepull and I can`t see if it has a brake hole, also no AC listed. That makes me wonder if they`re for 26 inch wheels. Also, no MSRP, but they do list QBP as the US distributor, so I assume they must be available.

I wonder how an old Fuel or Salsa Caballero would work out with drop bars. Considered doing anything like that? Or a Scalpel, maybe?

Back to suspension forks, the one I really dig is called the German A Kilo, (which for some reason weighs in at slightly over a half kilo). Unfortunately, the only way I know of to get one is to buy a whole Dahon Jetstream, which isn`t cheap :(. Also, it`s for a 406 wheel.

Thanks for the answers to my previous questions.

Does the steering stabilizer rattle at all? I think I need to get one of those. I'm tired of having my front wheel flop around on me while I'm trying to work on the bike or lock it up, and I've already got some scratches on my new frame from the brake levers hitting the top tube when the wheels swings around.

Also, partially because of this thread, I'm considering a Thudbuster ST. I imagine it being a worthwhile upgrade to my commuter/tourer.

Stabilizer does not rattle at all. It is a VERY weak spring, though so don't go in thinking it is going to do all that much. Just want you to understand that before you go buying it. It works, but barely. I still love it. :D

Look at the spring thickness at the bottom of the picture.
