Help with repairing hope hubs (Ti/Ti glide)

[ishaw]

I took delivery of some wheels today but sadly the hubs were a little worse for wear. The bearings front and rear need replacing, and the freehub had come off in transit, spilling the springs and pawls inside the box. Somehow or other one of the springs is MIA (hopefully in a nook in the box I haven't yet found), but if AWOL, does anyone know what freehub body I can replace it with i.e. standard shimano?

If it is possible to replace, how do I fix it on, as it obviously came off for some reason which I assume is down to it not being held together correctly.

Now down to the bearings. Does anyone know what I need, where I can get them from and how to replace them (both wheels)? Will the axles need replacing too (I hope not).

I want to salvage the wheels as aside from the above, the blue hope hubs are at least in good cosmetic condition, and the rims true, and should I get these up and running, a set of spins could be up for sale.

I don't mind getting my hands dirty and trying to fix without LBS assistance, so any bhelp/advise gratefully received.

Cheers in advance

Hello Ian...

I just bought a brand new set of pawls and springs for my Ti-glide from here - http://www.wiggle.co.uk/m/cycle/7/Hope/

Scroll down the page to Hope Hub Spares !! Got the lot

What holds the freehub on is a small ally collet with an incy allen key fixing. Once its all squashed together when the wheel is on and tightened by your skewer there's no way its coming off

Be well worth buying the bits as there quite cheap !!

Regards
Derek

Thanks for the guide link dsp, looks simple enough though judging by the pictures in the guide, I'm missing the disc/washer that protects the bearing in the freehub. Don't suppose anyone knows where I can get one of these from or if there is something I can use instead?

Cheers

Bearings are available from any bearing shop for a few quid each.

Just quote the number from the race. Itll be something like 6903. That is the identification code for that size bearing and as long as it has that number, it will fit.

As the bearings are sealed units, the axles will be fine.

Springs and pawls are still widely available from Hope, and once fitted with fresh grease/oil they will last for a decade or more. They only usually break when someone services the hub with the help of a monkey!
The pawls are made of a high grade metal nowadays and last for decades. Early pawls for Goldtec and Middleburn were weaker metal and would wear away within a couple of years. I think the same manufacturer made them for all 3 companies.

Hope are still very easy to deal with if you are looking for some small unavailable parts. Give them a try first. They will often just turn out an old part if you ask them, as all their patterns for the CNC machines are stored on discs.

I had a problem with some middleburn hubs a good while back, which required some spaer ring for the axle, and I had it made by a local engineer. It cost £5 to make!

I haven't opened those hubs since that date, and that was about 5 years ago. They still feel super smooth and clicky.

Fitting pawls -

Apply the tiniest hint of grease in at the back of the pawl where it touches the freehub body[spring end]theres a little groove where it sits


Too much grease and the pawls get stuck to the side freehub body and dont engage the toothed ring.Worse still is 2 get stuck the the body and only one engages.only one pawl will tear out and cost much the replace,it could even damage the toothed wheel. :?
,the trick is to only use the smallest amount ,literally a wipe is all they need

Thanks for all the advise and tips so far, I'm awaiting delivery of some parts and bearings to hopefully bring these hubs back up to code, though am missing a spacer it seems - anyone know where I can het a drive side spacer from that will fit? Various shops sell current ones but I'm not sure if they fit (i.e. Wiggle, Chain Reaction Cycles etc).

Ti-glide.
Bearing are 6001, the freehub shouldn't fall of that easy. The bearing also shouldn't come out of the freehub that easy as a circlip should be holding at least one of them in.
In fact nothing should really 'just fall off'

The spacers at the end changed to push fit gromet type fitting (a bit of rubber in it keeps it there)

CRC sell drive side spacers afaik.

Here's what it might look like
