    I had snapped two spokes on the sprocket side so it needed to be removed to fit them in. Didnt get anything back from it which is very annoying as my rear magura is playing up now so could have done with the money from that for a new lever body nothing seems to be going right recently

    Thats because you don't give your bike any maintenance... you just wait until I'm home from uni to fix stuff haha

    Haha yeah its all good now, it took about 4 months in total before I could start climbing fully again. They never said what happened, just 'meh' pretty much!

    Waterproofing would definitely make things better. I used to wrap it in a bin bag while I had a shower but this got annoying. Maybe an exterior coating like gore-tex as you said could work, but it'd probably be expensive?

    Good project though! sounds very promising

    Glad to hear the arm is better but its a shame they never said what happened... must have been something on their part ;)

    I'm either looking into a whole new cast design or a wrap/bandage than could be used for both covering casts or as a bandage for keeping a dressing compressed on a wound.

    Expense is a big factor here, that needs some looking into still. In the end materials get developed and older 'versions' or alternatives become cheaper... this could be a design for the future haha.

    is it just your chain stretching?

    Dont think so, when I say I'm just going out for a little bounce around I mean it, it really is just a ride round the block.

    Never had an issue with integrated tensioner, are you screwing them all the way in to tighten the chain? Both sides?

    Sure am, I'm not that silly enough to tighten the chain without them. I guessed they were there for a reason.

    That might be the problem.

    The thing with this is that if I don't tighten on the loose spots then when the wheel goes around it gets slack anyway and the gap between the frame and chain is tiny. It is a fairly new freewheel so maybe it still needs wearing in. I've always tightened on the loose spots before and had no problem.

    I has a story...

    This is brilliant, thanks for taking the time to share that. Seems like water proofing is a common theme with nearly all of the comments. Matt, your arm looked worse in the second lot of x-rays compared to your first one, don't suppose they told you what happened? So much for the people at work feeling sorry, then again... someone has to make the drinks ;) If your still in the cast... hope it heals up soon!!

    Evening everyone,

    So... I've recently bought an Echo Lite 2011 frame (Thats the 20" one for those who don't know) to replace my old Zoo! Lynx frame. I was surprised to see the new integrated tensioners in place of using the snail cams that I've grown so fond of using. I've been setting up the rear disk and just taking the bike out for the odd hop around recently to make sure all is in working order and have come to notice that the chain seems to slack off more than it used to when using cams.

    Maybe its just because I haven't used these tensioners before and haven't got them set up properly. Has anyone else had this problem, and what was the solution? I do tighten the chain on the 'loose spot' so it is nice a tight if thats my first problem...

    Anyone know why snail cams have been scrapped?

    Thanks,

    James

    It's not hard if you have any kind of mechanical mind.

    Very true! First time I built a wheel was just because I had a spare one lying around so i just took it apart and wanted to see how far I could get with putting it together again without a guide... this was before I owned a spoke tool as well!! Lengthy work with a flat headed screwdriver!!! Since then I've built/trued wheels as a favour for friends.

    Isn't there a clever way you can waterproof phones with no visible effect or damage to internals? If you could incorporate that into a pot it would be great.

    Or instead of using water based solutions for the pot use oil based? They cut them off with that weird saw anyway so it shouldn't matter too much what its based on apart from contact with skin?

    Theres plenty of 'smart' materials that I could incorporate. Two that have caught my eye so far for this is, Gortex... this is completely water proof (well, stops water passing through) but still allows some factor of breathability due to its structure. The other was an impact polymer, found in POC cycling armour, its soft and flexible until hit or struck, it then hardens to protect the wearer. I'm still in the researching stage though really to see if any changes would be viable.

    Thats exactly what it did - although they're only currently suitable for ligament/tendon damage - i'm sure the idea could be adapted!

    They're also removable for showering and checkups - as they're held on with velcro.

    Thanks for the links, they look like they'll be helpful for research, I take it that you can only have an aircast over a full depending on the injury? So a stiff and more secure version of this would prove just as effective as a full, fibreglass cast? (potentially)

    the cast I had in that video was a "Temporary" cast, it had a slot down the front to deal with swelling. When I've had leg casts before (twice) they were full ones, built up with padding and fibreglass, I don't think any actual plaster was used.

    Breathability wasn't a huge problem, though I must admit it did smell a little towards the end, when I got it off I had loads of dead skin which was very satisfying to remove.

    I've also read that the surface fibreglass ones is quite rough, did you have any problems with that? I would have thought that if i could design a more breathable structure then this would combat the smell and possibly reduce the cause of dead skin.

    Thanks for all the comments so far guy, its been a great help. Never realised how good the forum could be for user feedback and research!!

    Thanks for the quick replies guys.

    Having to have casts replaced every week or so due to swelling going down and then rubbing like f**k was pretty annoying... When I did my achilles however, they put me in an air cast - which could be pumped up when required to bring back the stability.

    Did the air cast just allow for it to be adjusted to keep it fitting properly to combat the change in swelling?

    Not being able to get them wet was the biggest ballache I found. I had to put my leg in a bin bag and tape it to my thigh. It still let in a little water and pulled my hair out when I took it off. Some king of leg/arm shaped bag with some kind of re-usable seal would have been ideal.

    Itching was annoying too, but a spoke usually sorted that out.

    I also found my toes got cold, I did stretch a sock over the cast which helped a bit, but my toes still felt vulnerable. Some insulated sock thing with some kind of toe protector would have been good.

    Thanks Ali, I might put that video into my final presentation to show how you can still carry on what you love doing! I dont suppose you know what the cast was built up from? I think from a little research that theres a padding of sorts on the skin then a hard plaster or fibreglass bandage over that... is that correct?

    Waterproofing the cast was my first insight, another was to try and make it more breathable? What was it like when you had it removed?

    Hello everyone,

    I'm studying product design at Plymouth Uni and our current brief is regarding healthcare... pretty broad I know. I've narrowed down to looking at the casts applied when bones are fractured or broken.

    I am pretty lucky to not have broken any bones though my riding (touch wood) however the insight from someone who has would be really helpful! I looking mainly for information on what sort of problems you found while having/wearing a cast or things that it effected in your life.

    Any help would be greatly appreciated!

    Many thanks,

    James

    Considering that we know a chap that works at this shop, who can be quite cocky about how good they are at providing good service/range of tools they have, you should certainly complain!

    Ollie if I was you I would of put my big boy pants on and have a good go at them! Why on earth did you even give them the money?

    Absolutely awful bit of work resulting in broken parts. He's royally f**ked you over considering you gave him £50 for this shit!

    Exactly, the mentioned employee is always going on about how much better being a 'trained' bike mechanic is.. blah blah blah. If this was my wheel, i would have definitely kept the money for building it, I would have needed it for a new sprocket after they had destroyed it!! I know removing a sprocket can be a pain the the arse but to resort to what looks like a grinder to remove it.... Madness!

    I know that it's really bad to destroy things like that. But I don't think it's fully right to call them "unprofessional"... Of course they haven't seen a trials bike before, and I guess that they never had even touched one with a allen key, so how could they know how to properly remove a screw-on sprocket then? Of course you all know how to remove the sprocket, but I don't think that you know how to service a DH fork either (just a example).

    I have know f**king idea though whey they want to remove a sprocket that they're clearly not capable of removing or even know about.

    Thats a fair point, I don't remember calling them unprofessional. As for never seeing one, a friend of mine works there who used to ride one, apparently this wasn't his handy work though. And removing a screw on sprocket shares similar methods on how to remove other parts like cassette lock rings and freewheels. It's not like theres much on a trials bike to know about but i can see where your coming from.

    Like most things... If i dont know hos to do something.. I google it!! They could of done the same!!

    Exactly! I found Adams tutorial on how to do this which is a doddle and I use the same technique every time I need to.

    Because that's unlikely to work, they are on there REALLY tight. There are a couple of ways to get them off, but a local bike shop is unlikely to figure them out.

    The hub while being damaged, is still perfectly usable. Not that I'm defending the shop as they shouldn't be damaging anything. I assume he wanted to keep the cog though, was this expressed when he took it in?

    I've always used the method that Adam posted on the Tartys site, sometimes it can be a struggle but I've always managed to get it off after a bit of hard work and effort. No idea if he specified wether he wanted to use the sprocket again... guess the shop decided that themselves.

    Oh my word!! Please name and shame the shop.

    And just for you Brad... Westham Cycles in Weymouth.

    wtf

    why not use a chainwhip or gently clamp the socket in soft jawed vice to get it off by turning the wheel.

    was it a Halfords by any chance ?

    i know they get bloody tight but that's something else i hope your friend stands up for himself and either gets them to replace the hub and cog or gets his money back and demands a new cog.

    It wasn't Halfords, just a standard local bike shop, good for most things, just not trials I suppose after this. Considering this was on a 26" wheel and I can manage to remove sprockets from a 19" wheel build they shouldn't of had too much problem given the extra leverage!! Oh and I forgot to mention...

    They charged him £50 for the wheel build!!
