JoNnY__Mc Posted June 30, 2006 Report Share Posted June 30, 2006 hey people... i have recently bought an eno freewheel... in running it on echo 04 front freewheel cranks with an echo bashring... my bb is 127.5 in length... and the mofo is still rubbing its actually quite dissapointing really as i have just payed £40 for it :| so like... what should i do? how can i prevent or fix this? i am deffinately not grinding the tabs off... and i dont really have the money to get a new bb... and i dont think they make them any longer than 127.5 nothing seems like an obvious solution to me other than buying a different freewheel what can i do Quote Link to comment Share on other sites More sharing options...
King C Posted June 30, 2006 Report Share Posted June 30, 2006 It should fit just fine but if not maybe machine the bash down so that it is thinner and therefore more clearance. only a suggestion. Quote Link to comment Share on other sites More sharing options...
downhill_rob2@hotmail.com Posted June 30, 2006 Report Share Posted June 30, 2006 (edited) Is the Echo bash a UCI style one?Or is is like 1cm thick?If its like 4-5mm thick, then it should fit....EDIT: just looked, the Echo bash is 10mm thick, you really should get the Tensile UCi bash, and it WILL work, and you should ride UCIUCI for life!

JoNnY__Mc Posted June 30, 2006 Author Report Share Posted June 30, 2006 (edited) will try that now mate... it might not be an echo bash... im sure it is... its old ... was thinking of trying to do a straight swap with someone for a brand new tensile... smart move/ would someone do it????

Mark W Posted June 30, 2006 Report Share Posted June 30, 2006 Wait.Square taper or ISIS?I'd put money on taper Quote Link to comment Share on other sites More sharing options...
Jaffacakes Posted June 30, 2006 Report Share Posted June 30, 2006 You can get spacers for BB's so the Eno won't rub on the BB.Mine was doing this a few weeks back so I couldn't do my crank's up tight without it rubing. So me being me I got bored after a few day's and rode, now I have f**ked cranks and my Eno Tab's have taken a beating Im not sure where you can get spacer's from though...

Dan6061 Posted June 30, 2006 Report Share Posted June 30, 2006 Got the right cup size BB in your frame?Not sure if that could be the problem or not.. Quote Link to comment Share on other sites More sharing options...
Mark W Posted June 30, 2006 Report Share Posted June 30, 2006 Seeing as he said 127.5mm BB, and the fact it's rubbing, I'm inclined to think that he's got square taper cranks, he's done them up as tight as he can and has therefore splayed the tapers, meaning it has to sit super far on to be tight. 'cos of this, the tabs rub 'cos you're effectively now using a shorter BB due to how far the cranks sit in on it. The only real remedy is new crank arms, a new freewheel, or a grinder. Spacing it further out won't really work 'cos it won't be tight on the taper if it's further out. You could just try not doing it up so tight and just doing it by feel, or get a torque wrench off someone and do it up the right amount and hope for the best...If they're ISIS, that's weird. Veeeeeeeerr weird. Quote Link to comment Share on other sites More sharing options...
JoNnY__Mc Posted July 1, 2006 Author Report Share Posted July 1, 2006 (edited) yeah its a taper bb ... i havent tried to put it on super tight though... cause i just knew it wouldnt fit... and then when i tried.... it didnt fit im gonna try and machine down the bash today and hopefully that will work... i'm hoping that by making the bash thinner i will create more space for the eno to fit onto... hard to explain but there is a theory behind it.... problem is i've got the feeling my cranks are also f**kered, like the slot for the bb to go through (im sorry i dont know the actual name for it) has widened... i think... i really cant afford new cranks and a new bb :| because looking on tartybikes... isis is expensive and there is no way im buying taper again because im too heavy for it Edited July 1, 2006 by JoNnY__Mc Quote Link to comment Share on other sites More sharing options...
Mark W Posted July 1, 2006 Report Share Posted July 1, 2006 The slot the BB goes into are the tapers, which is what I was refering to. How much room is there between the inside edge of the tabs (so the inside edge of the freewheel body, closest to the crank arm) and the end of the threaded part? That's largely going to limit you to how thin you can make your bash, 'cos basically, if it can only ever go on another 1mm, and you take 2mm off your bash or whatever, it's not ideal.

JoNnY__Mc Posted July 1, 2006 Author Report Share Posted July 1, 2006 (edited) lads... i have sorted the b*****d... well kris did... i just watched and feared for my cranks... what he done:- grinded down a small part of the bb cup (making it thinner by about a mm) therefore giving more clearence but not taking too much away that thers not enough left for a bb tool to go into- grinded down the bashring to about half its thickness and removed the spacer that was there before, gained a couple of threads for space and gave about 4/5 mm more space...- problem... now its not the actual eno causing the problem... the eno couldnt move any further down meaning the echo bash was free to move and wobble and the eno would not tighten anymore because of how its built- solution... kris grinded down the cranks (the bit where the threads are) about 3mm down and then carefully filed/smoothed/fixed (i dunno what he did.... call it taken care of) the opening threads on the cranks....hope you can understand what we have done and maybe its a reference for people stuck in the future....or the topic can be closed as the problem has bin fixed Edited July 1, 2006 by JoNnY__Mc Quote Link to comment Share on other sites More sharing options...
Mark W Posted July 1, 2006 Report Share Posted July 1, 2006 Just so's you know - you could've just slid a BB spacer (the ones that reduce a BB from 73 to 68, they're 2.5mm thick) on before your freewheel, and it would've taken up that space. But yeah, good bodging anyway I'm liking the "Measure once, cut twice" policy too Quote Link to comment Share on other sites More sharing options...
Krisboats Posted July 1, 2006 Report Share Posted July 1, 2006 Ha ha this was some great bodging. Unfortunately though mark we already had a bb spacer in between the bash and the freeweheel and it was partially the cause of the problem.What i did to the cranks was grind the top few lines of thread and crank arm from the crank... levelled it off with the grinder and then filed the threads so they were all neat and tidy again... I got them so perfect the freewheel just slid on without a problem. I also grinded the inside of the bash so it was all flat instead of being concave (i think thats the right one) so the bash was about 3/4 of its original size, therefore, removing the need to fit the bb spacer that was there to seperate the freewheel and the bash.We got it working though so thats good, it now has an amazing 1/2 mm'ish of clearance The moment was kind of ruined though when i managed to strip the threads in his four bolt mount on his frame when i was setting up his brake :$ Fixed iot for him though And jon, i think pictures are in order Quote Link to comment Share on other sites More sharing options...
