Michael Hardman Posted January 26, 2005 Report Share Posted January 26, 2005 It cam to me in a dream (actually just as I woke up). You hear a lot of complaints regarding the life of the bearings in ISIS BB's. Well I had asimple way of fixing this problem but it requires a new industry sandard. Basically BB shell should be made bigger, the size of BMX BB but with threads in. This would allow for bigger brearings and would possibly increase the life of BB's. Anyone agree with me, or not, critisie a way (not may spelling I know its bad) Quote Link to comment Share on other sites More sharing options...
Brisa Posted January 26, 2005 Report Share Posted January 26, 2005 Lol, you and your dreams. I remember a while ago on the Mbuk forum you had an idea/dream about making ratchets in hubs bigger with a larger free hub or something. It could be done but it might not be too trials friendly. Look at euro bb's on bmx, they seem to get on ok with them but really its just an isis bb which trials would kill. In theory with a nice light alloy axle/cups it could probably save weight over a standard bb and would be just as strong/stronger. Would require a lot of companies to take it on though. Frame choice would be limited etc. Quote Link to comment Share on other sites More sharing options...

hititfaster Posted January 26, 2005 Report Share Posted January 26, 2005 Is that something similar to the Fly BMX Spanish BB? They tried to get it to catch on a while ago as BMXres were destroying MTB (euro) BB's and USA BB's were a bit old and heavy. Quote Link to comment Share on other sites More sharing options...
Michael Hardman Posted January 26, 2005 Author Report Share Posted January 26, 2005 I have no clue at all. But what I do mean is that trials bikes use bmx bb shells (the big ones that dont have threads in) and whack a thread in. Allows for bigger bearings.

Matt_Tupman Posted January 27, 2005 Report Share Posted January 27, 2005 Or instead you could get rid of bearings completly and use teflon of brase bushes :P" just an idea :ermm: to be onist though I find BB's last quite long, my year old Raceface has just started to develope some play in the bearings :ermm: Quote Link to comment Share on other sites More sharing options...
Tomm Posted January 27, 2005 Report Share Posted January 27, 2005 I'm sure it has more to do with the standard of manufacturing that's used, rather than the actual design. Some BBs last, some don't. Quote Link to comment Share on other sites More sharing options...
