Ash-Kennard Posted February 26, 2007 Report Share Posted February 26, 2007 to be honest its not rocket science, do it yourself if you want one, all you need is an anle grinder and thats what 10er, 15maybe. your not going to send it back everytime you need a grind.

If I asked my dad if I could buy a grinder and have a go on my rim if I was 13 he'd probably have none of it.It was just a thought.Phil Quote Link to comment Share on other sites More sharing options...
Ash-Kennard Posted February 26, 2007 Report Share Posted February 26, 2007 i rode smooth when i was 12/13, i didnt need the braking advantage anyway in those days Quote Link to comment Share on other sites More sharing options...
Phil H Posted February 26, 2007 Author Report Share Posted February 26, 2007 i rode smooth when i was 12/13, i didnt need the braking advantage anyway in those daysAllready adressed that point in crticisms on the first post Anyway don't think we are getting anywhere here. So in conclusion personally I think it is a good idea and isn't necersarrily unefficient if done in a factory as part of the manufacturing process although many people disagree and think that kids dont need the braking power and don't really see any other points against it except that its unnecersarry.Phil Quote Link to comment Share on other sites More sharing options...
Danny Kearns Posted February 26, 2007 Report Share Posted February 26, 2007 Tarty already offer a free set of rock pad greens with all beginner bikes. (See the website for more details.)It is a good idea if it is a OPTION but for them to come as standard with a grind is not acceptable in my opinion.Dan.......................

boon racoon Posted February 26, 2007 Report Share Posted February 26, 2007 A manufacturer doesnt recieve a bike fully made. They 'manufacture' them, so as I see it, it would just be another step in the chain of producing the bike.i probably used the wrong word. i meant the people that receive the bikes here in the UK i.e monty, tarty, koxx etceven back where the bikes are assembled there are probably parts sourced from all over before they're shipped in a box.

I didn't know they did that!Yeh fully agreed.I think that would be the best way by far as long as there was a section to explain what a grind is to beginners an an option.The Answer^^^^^Cheers for everyone's input.Phil Quote Link to comment Share on other sites More sharing options...
Krisboats Posted February 26, 2007 Report Share Posted February 26, 2007 I don't think the problem with grinding your rim leading to alzheimers is something that should concern the majority of people. I thought its just that because the enodising layer on the echo rims is so tough it takes more work to grind it off, resulting in more dust. Which would be ordinarily nothing to worry about if you grind your own rim every few weeks/months, but if your working at tarty's grinding everyones super thickly coated rims, then its going to be a much more serious issue.Onza used to sell bikes with grinds, but don't anymore as i guess it just wasn't neccessary.

Effects on Humans: Aluminum dust is an eye and respiratory tract irritant in humans. Soluble aluminum salts are irritants when inhaled as aerosols [Hathaway et al. 1991]. Although inhalation of aluminum powder of particle size 1.2 um, given over 10- or 20-minute periods several times weekly resulted in no adverse health effects among thousands of workers over several years, several other studies report X-ray evidence of pulmonary fibrosis [Hathaway et al. 1991]. Some patients on long-term hemodialysis develop speech disorders, dementia, or convulsions. This syndrome is associated with increased concentration of aluminum in serum, brain, muscle, and bone [Amdur et al. 1991; Hathaway et al. 1991]. There is some evidence that Alzheimer's disease may be linked to aluminum content in the body [Amdur et al. 1991]. Analysis of the aluminum content in the brains of persons dying from Alzheimer's have shown increased levels, although brain aluminum levels vary greatly. A second correlating factor is that neurofibrillary tangles (NFTs) have been identified in both aluminum encephalopathy and in Alzheimer's disease [Amdur et al. 1991]. However, it has been shown that the NFTs produced by the two conditions are structurally and chemically different and that NFTs are present in several other neurological disorders. It appears that the aluminum content of the brain is less an issue relating to exposure to aluminum than an issue of a blood-brain barrier defect or compromise of some kind [Amdur et al. 1991].For those who care for a link...

AdamR28 Posted February 27, 2007 Report Share Posted February 27, 2007 Also, if someone like Tarty started offering new bikes with the option of a grind (free or small charge) this would give them a massive leg up againt the opposition selling trials bikes for similar prices.We already offer that as a service.Hope tarty bikes will have some input on this discussion.....PhilFree smooth rim brake pads (Rock Vs on V brake bikes, Rock Greens on Magura-equipped bikes) with every complete bike, as Danny said That's the best solution we could come up with. I certainly wouldn't wanna be grinding a customer's rim without their full approval!Seriously if there are health hazards associated with grinding some rims then we should know about it.Facts please,Ben.See above.Cheers for the info Paolo, seems like there are small links - I don't spend as much time grinding aluminium as some people will (welders etc) but I don't wanna be taking any chances! In a typical week I'll probably spend around 30 mins grinding rims, the charges we apply through our website are to cover new discs, eye protection and dust masks. I'm sure there must be some health consequences from inhaling anodising powder too... It certainly makes a right mess of our unit, even the guy round the front of the building who makes ironmongery for a living was shocked at the dust the Echo rims give off!Adam Quote Link to comment Share on other sites More sharing options...
Davetrials Posted February 27, 2007 Report Share Posted February 27, 2007 ur not gonna get f**king dieses from griding your rim, unless u stand in the wind sucking in as much of the rim as u can,im so annoyed at how f**king stupid this post isstop over reacting ffs, is the same kinda thing as working with asbestos, u can work with it for years and it wont bother u, ud only start dying when ur sucking on the sutff.

Ali C Posted February 27, 2007 Report Share Posted February 27, 2007 haha, you should see the tartybikes kettle dave! after a few rim grinds its full of aluminium power....perhaps having the "kitchen" next to the grinding station isnt the healthyest thing in the world Quote Link to comment Share on other sites More sharing options...

20inchsuperstar Posted February 27, 2007 Report Share Posted February 27, 2007 when i sanded down my try alls so it was all nice and smooth, it was pretty cool, i was all fluroey, the dust that came off it was huge!i havent got any diseases as of yet.its just a warning, to tell you what could happen and to take precautions to stop that happening.matt Quote Link to comment Share on other sites More sharing options...
Captain Scarlet Posted February 27, 2007 Report Share Posted February 27, 2007 I am aware most people when getting into trials on their first bike wouldn't be doing anything extreme but I still think it would be useful.But surely its the beginners who need to have their brakes working as well as pro's, as they are trying news things, brakes will stop them from going over the back.I always wondered why some top spec bikes don't come with boosters?

What you just said is exactly the point of the whole thread. That beginners need good brakes too and won't know much about grinds etc Anyway it all sorted as Tarty Bikes have explained that they do smooth rim pads with new bikes for beginners and that a grind is a cheap option when buying a new bike from them.Not sure how everyone got into a huge discussion about getting disease from grinding.I'm preety sure this thread is over.Phil Quote Link to comment Share on other sites More sharing options...
N.Wood Posted February 27, 2007 Report Share Posted February 27, 2007 Just give them a lump of tar?A leaflet would be good. Quote Link to comment Share on other sites More sharing options...
-Matty- Posted February 28, 2007 Report Share Posted February 28, 2007 I have never grinded a rim and i run a avid vee on the rear with nokian cable with monty pads and its amazing, better than any magura i ahave ever used! Quote Link to comment Share on other sites More sharing options...
Jason222 Posted March 1, 2007 Report Share Posted March 1, 2007 Alright, why not just use tar on the echo rim and ride it until the anodized layer is gone, and then grind? Quote Link to comment Share on other sites More sharing options...
