Chris Borneo Posted April 9, 2012 Report Share Posted April 9, 2012 (edited) Got a Pro 2 Evo trials hub on the rear. Only a few weeks old but it's already slipping. Not all the time. Maybe once every other ride but seems a fair bit for a new hub, no? Anyone else got this hub/have the same problem? Runnig 24/12 so hardly torquing it. Always slips just as I start cranking at something. Edited April 9, 2012 by Chris Borneo Quote Link to comment Share on other sites More sharing options...

murph82 Posted April 9, 2012 Report Share Posted April 9, 2012 does it need bedding in like a freewheel? I had same problem but mine wasn't new. My chain was upside down and the chainline was out where i changed the original wheel out and i have a cheap fixed tensioner. Needed to move the jockey wheel over!

Chris Borneo Posted April 9, 2012 Author Report Share Posted April 9, 2012 Could it be chain slip or do you mean skipping?? Have you flushed gt85 through the hub?? Skippin, slippin, whatever you want to call it, it's definitely the freehub. Don't really fancy flushing it with GT85. Pretty sure a brand new hope hub's gonna be lubricated already and I'm not sure GT85 is the right stuff to use anyway is it ? Quote Link to comment Share on other sites More sharing options...
Ali C Posted April 9, 2012 Report Share Posted April 9, 2012 without being rude and calling you a liar, but are you sure it's the hub? It seems very rare that the Hope hubs skip. what tensioner are you running? Much chain wrap around the cog? Quote Link to comment Share on other sites More sharing options...
Blake Posted April 9, 2012 Report Share Posted April 9, 2012 Can't go wrong with GT85, thins out grease that's too thick and lubes it up really nicely and lightly Quote Link to comment Share on other sites More sharing options...
Ali C Posted April 9, 2012 Report Share Posted April 9, 2012 Can't go wrong with GT85, thins out grease that's too thick and lubes it up really nicely and lightly the trials hubs don't come with grease, they come oiled so you shouldn't need to do that. 1 Quote Link to comment Share on other sites More sharing options...

It seems very rare that the Hope hubs skip. what tensioner are you running? Much chain wrap around the cog? Running an old short cage mech, set in place with the limit adjusters, all lined up nicely with plenty of chain wrap. I'm really surprised it's slipping too, especially with the amount of noise it makes, doesn't sound like there's an engagement problem. Also been running an old bulb hub for the last few months with no problems so not best pleased that this one's slipping. If no one else is having any problems, I guess I'll have to drop an email to hope n see what they say. Quote Link to comment Share on other sites More sharing options...
FamilyBiker Posted April 9, 2012 Report Share Posted April 9, 2012 does it slip under noise or silent? Quote Link to comment Share on other sites More sharing options...
JD™ Posted April 9, 2012 Report Share Posted April 9, 2012 Fancy getting a couple of pics of your setup posted up? Side on from the drivetrain side (obviously) and along the chainline from the back. I know you've said that's all cool, but it'll help make sure and you never know what someone might spot that you've managed to overlook.

Yeah, I'm at my parents working on my car at the moment but I'll put up a couple of pics later. Quote Link to comment Share on other sites More sharing options...
ogre Posted April 9, 2012 Report Share Posted April 9, 2012 have you opened it up and had a look inside? if you've got chain wrap, good alignment and i pressume the condition of you chain and sprocket is fair? that kinda puts it all on the hub being the weak http://www.youtube.com/watch?v=fdgUvv76H28(click for service guide) Quote Link to comment Share on other sites More sharing options...
Andeee Posted April 9, 2012 Report Share Posted April 9, 2012 without being rude and calling you a liar, but are you sure it's the hub? It seems very rare that the Hope hubs skip. +1 I too have never come across a hope hub skipping and ive had a mix over the years such as xc,s pro2's, monos and bulbs and they have all been fine. Not to sound a smart arse you could have a stiff link? worn down tooth on either cogs or slack tension. Quote Link to comment Share on other sites More sharing options...
Duncy H Posted April 9, 2012 Report Share Posted April 9, 2012 You say you bought the hub new so you could have a new sprocket on there? If a combination of worn chain and new sprockets are used or visa verca then it could possibly skip. Quote Link to comment Share on other sites More sharing options...
Chris Borneo Posted April 9, 2012 Author Report Share Posted April 9, 2012 Chain n sprocket were new together not long ago, got plenty of tension on the chain and the chainring's still got loadsa life in it. Gotta be the hub that's slipping. For any doubters I'll put up a pic up tomorrow. Quote Link to comment Share on other sites More sharing options...
Ali C Posted April 9, 2012 Report Share Posted April 9, 2012 I'm a little sceptical about the 12 tooth rear cog Quote Link to comment Share on other sites More sharing options...
Skoze Posted April 9, 2012 Report Share Posted April 9, 2012 Likewise. What sprocket is it? And are you using both the jockey wheels on the mech? Quote Link to comment Share on other sites More sharing options...
dezmtber Posted April 9, 2012 Report Share Posted April 9, 2012 try opening the hub freehub body and checking the pawls and the teeth on the drive shell inside the hub body for any damage. most of the hope hubs i have seen are built with the same sort of greace in tensile freewheels. it can help to clean it out and replace the greace with chain oil for wet conditons.

Ali C Posted April 9, 2012 Report Share Posted April 9, 2012 Pro 2 T or Pro 2 Evo T hubs aren't built with that grease at all. Quote Link to comment Share on other sites More sharing options...

Chris Borneo Posted April 9, 2012 Author Report Share Posted April 9, 2012 Sorry, I should also have said before, I can tell the difference between a chain slip and a freehub slip. It is the hub. Quote Link to comment Share on other sites More sharing options...
manuel Posted April 9, 2012 Report Share Posted April 9, 2012 Unless you've got some pretty awesome wrap, and got some fantastic tension, I'd tend to go with the 12t rather than the hub. But pull the hub apart and make sure everything is in the right place - it only takes a moment* *first time apart may be a bugger. Quote Link to comment Share on other sites More sharing options...
Chris Borneo Posted April 9, 2012 Author Report Share Posted April 9, 2012 Not very reliable method I have to say. Worked on my old bike for about 3years. About as reliable as I need really. Quote Link to comment Share on other sites More sharing options...
Ali C Posted April 9, 2012 Report Share Posted April 9, 2012 Running a gusset single speed sprocket not one nicked of a cassette. Chain is wrapped tight round it through both jockey wheels. It's not about how 'tight' it's wrapped, it's about how many teeth on the sprocket come into contact with your chain. If you get a photo up that'd make it pretty clear straight away...
