rosslittledubber Posted July 29, 2013 Report Share Posted July 29, 2013 Hi people, my freewheel decided to start slipping the other day, it still bites under half load, but full load it slips :/ also i am unsure of where to source parts from as im not sure which hub it actually is, all i know is that it is profile and the sprocket is splined onto the hub, so the freewheel mech must be inside the hub. I can get pictures of it but my gash windows phone will not let me post them on here so it would be email only :/ Any help or advice etc would be cosmic please, thanks Quote Link to comment Share on other sites More sharing options...
Shaun@FlawlessBikes Posted July 29, 2013 Report Share Posted July 29, 2013 Hi, I am currently running a Profile Bmx hub and the advice I have been given is to change the springs to Primo ones otherwise it would start skipping, I'm not too knowledgeable with profiles but I hope this helps Quote Link to comment Share on other sites More sharing options...
rosslittledubber Posted July 29, 2013 Author Report Share Posted July 29, 2013 it does look rather like the profile mini hub tbf.. Your diagnostics would make perfect sense, i did a backhop and it was fine, went to do another backhop and it just started slipping, so hopefully it is just the springs or something simple, hope so because it seems a decent hub to be honest.. Thanks dude Quote Link to comment Share on other sites More sharing options...
bing Posted July 30, 2013 Report Share Posted July 30, 2013 I had this with my old profile, turns out the driver ring was spinning in the hub shell 1 Quote Link to comment Share on other sites More sharing options...
SamKidney Posted July 30, 2013 Report Share Posted July 30, 2013 Profiles seem to be really hit and miss in terms of reliability. I had one on my old Python and ditched it for a front freewheel setup very quickly. Get it looked at and fixed, and then maybe look at selling it on. They seem to still have a good second hand selling price on them. I managed to get £130 for mine by selling it to a BMXer. Quote Link to comment Share on other sites More sharing options...
rosslittledubber Posted August 2, 2013 Author Report Share Posted August 2, 2013 (edited) So finally stripped my hub.. It appears the springs are made from chocolate, new spring and pawl kit ordered, primo ones at that.. £7.99 bargain.. Also sent in a new 12t sprocket for the rear that comes with a spacer and new nut.. New chain for good measure also.. Should cure the problem nicely i hope Edited August 2, 2013 by rosslittledubber Quote Link to comment Share on other sites More sharing options...
bing Posted August 3, 2013 Report Share Posted August 3, 2013 Don't grease it when you reassemble it, use some light oil sparingly, like gun oil or 3 in 1. Grease will make it sticky and will skip again Quote Link to comment Share on other sites More sharing options...
