    Pantour suspension hub

    Hi everybody,

    I'll be in NY city soon and like to buy a Pantour suspension hub there but I wasn't able to find any appropriate dealer there.
    Does someone know any shop in NY city where I could buy one ?

    Thanks a lot in advance
    Val.

    All the posts I've read about Pantour hubs over at www.bentrideronline.com have been fairly negative. Unless you are totally sold on them I'd jump over there and do a search to see what other folks' experiences have been. They seem to have significant reliability issues given the cost/benefit they provide.

    Hi vik,

    Thank you very much for your reply.
    Is that so ? I heard many different opinions about the Pantour suspension hub, I just wish I could have tested it. The vibrations of the front wheel of my Brompton are really disturbing when I ride more than 20km, that's why I was looking for a suspension. Larger tires are sadly, as far as I know, not compatible with a brompton. I also heard about reliability issues with the Pantour hub, but I thought this had been fixed with the new models.

    Thanks a lot for your help,
    Val.

    Yes, the reviews are positive and negative.

    The hub softens the ride nicely and many who use it, are very happy because of that. For a brommi with s-bar I think: yes, it adds comfort. Also Dahon uses (or used?) the hub in some of their models. I have long searched for all reviews and it seems that the bigger problems are on the rear hubs for example with disk brake mount. The front hubs seem to work more reliable.

    On the other side there are complaints about customer support. The website seem to have not changed since years and is quite odd. And the hub seems to have difficulties to withstand hard and heavy rides or load for a longer time (for example if the Brommi M-typ is loaded with the touring bag).
    I have a pantour in my brommi and like the ride much...but I got it only recently and would probably hesitate to go with the hub on a longer trips, say for on a tour with pannier for lasting several weeks/month.

    I want to emphasize I'm only reporting my impressions of what I've read. I don't have any direct experience with Pantour. I generally wouldn't bother posting in such situations, but what I have read has been so uniformly negative [in the recumbent world] that I figured it was worth a word of caution.

    I have a Dahon Jetstream with the Pantour front hub. When I bought it, I received scant information on the hub and ways of adjusting it to suit a particular bike/rider. There are a pair of screws on the sides of the hub that can be put into one of several holes. Which hole is determined by the fork/head tube geometry.

    The other issue I ran into is that because I am evidently heavier than the average rider, the elastomer in the Pantour hub would "bottom out" just under my weight, providing no suspension effect at all. Dahon was no help with my problems, but eventually, being dogged, relentless, and obnoxious I was able to correspond directly with a Pantour engineer in Germany. Ultimately I found a durometer on eBay (a device which lets one measure the hardness of things), took apart my hub, measured the hardness of the elastomer blocks in my hub, and replaced them with a harder urethane. Since then my hub has been performing like a champ.

    I suspect that people who experience reliability issues with the hub have overloaded it, defeating the suspension and causing a situation wherein the hub would just beat itself to death. If I were going to go touring with a Pantour hub, I would load up the bike, check that there was still adequate deflection of the susupension, and replace the elastomer accordingly.

    There are some lengthy discussions detailing the experiences of myself and others HERE and HERE.

    Thanks for that post
    As far as I know, Pantour offers two different elastomer, one softer and one harder depending on the rider weight. Was the urethane elastomer you mounted from Pantour? Or what was it? Did you have to modify it?
    I also have read that the elastomer, being a wear and tear part has to be checked and eventually changed. Its a pity that their is not so much info about that, I suspect that also has caused trouble for some.

    I just changed my elastomer on my Pantour hub fitted on the Speed Pro. US$11 - no big deal. Old elastomer broke after 700km. My impression of the hub is that yes, it does work slightly but fitting Big Apple tires is more effective. But if you are stuck with the Brompton or a Tikit, than this just may be your cup of tea.

    My hub came with a 40 Shore elastomer. The heavy duty one I replaced it with is 50 Shore. 45 Shore would be perfect.

    Are these replacement elastomers for the Pantour hub obtained only from Pantour, or are they generic and readily available?

    After my lengthy correspondence with Pantour, which included a phone call to Germany, they sent me their stiffer elastomer gratis, and asked me to test it in my hub, with the screws in each of the several locations, and report back with my observations. Generally I would say that the screws should be set in a position that makes the direction of movement of the hub at an angle about halfway between 45% and parallel to the head tube. This is with the adjusting screws resting against the front of the dropout. Remember that the Pantour hub has a left and right side, and that if you remove the wheel you must take care to replace it properly.


    Left: A cutaway drawing of the Pantour hub shows the simple urethane blocks which can be easily fabricated by anyone with a ruler and a matte knife. Right: this drawing shows the left/right orientation of the hub.

    AFAIK, you can order the elastomer from Pantour or any of its distributors. That said, the elastomers are just cut blocks of urethane, and one could easily get Shore 45 or 50 urethane bars and cut the block to size with a matte knife or razor blade.

    A phone call to a German engineer when Pantour sits in Vista, CA. thats hard.

    Friday my Pantour arrived from US and spare elastomers came with it. The package needed about 6 weeks in the post and Dena Lund from pantour has been very helpful and reassuring, promt answering to emails.

    Is this angle optimized for the suspension effect or to provide rim-surface for braking? Did you find any negative effects upon braking or upon the brake itself?

    I was out bid on a pantour hub on ebay

    I was wondering how they would effect rim brakes
    guess it doesnt move very far.

    how does it affect handling
    I heard that old Triumph motorbikes that had sprung hubs were scary

    Optimized for suspension. The suspension travel is mechanically limited. My front rim does have a particularly wide braking surface to accommodate the hub.
