Hi all,
I'm in need of replacing the Pivot bearings on my 2019 Trek remedy 7 and was wondering if there's a go-to bearing/kit supplier in the UK? I realise the bearings are each identified (on the outside race I believe) however I would prefer to only remove them once I have the replacements if possible.
Many thanks in advance,
Pierce

Hi Pierce, Simply Bearings is one company that will supply suitable bearings but there are plenty of other reputable bearing suppliers in the U.K.

The size code on standard bearings will be visible as it's stamped on the bearing seals on both sides so you should be able to see the codes in situ just by looking. Advise a torch and possibly a magnifying glass as code numbers are small and hard to read.

The only reason you will need to remove the bearings first is if they are non standard and don't have a code stamped on them but this is unlikely for pivot bearings.

For non standard bearings the only way is to remove and to accurately measure dimensions or take them to bearing supplier to get matching replacements.

Thank you very much. Do you know if Manufacturers issue anything like a bearing spreadsheet stating the bearing sizes and quantities featured on their bicycles?

You're welcome Pierce! Smile I don't know of anywhere there would be information regarding all bearing sizes for a certain bike. I personally never bothered looking to be honest.

There are companies that do 'bearing kits' for specific bikes, i.e:- a full set of 10 bearings together to fit a certain bike for example.

These kits are handy if the bearings aren't standard sizes and save the hassle of measuring and sourcing them separately but they are more expensive than buying average bearings.

It is worth seeing if you can get codes first and write them down for future installs and only need to do it once for the first time.

On the off chance bearings have no codes You could try Kinetic Bike Bearings or MB Bearings, based in the U.K. and maybe they will supply the specific kit for your Trek's, model and year?

My thoughts were more towards how bike shops might replace bearings. Naturally it could be quite inconvenient for a customer if you have to order their bearings in after having received their bike...meaning they'll be without the bike for longer. These companies making business from selling the kits must be getting their information from somewhere

Update..
I contacted Trek Customer support who kindly supplied me with the documentation for the 2019 remedy. They stated that this documentation was on request only and didn't feature on their website which is useful.

Many thanks again for the help

Maybe shops and bearing kit suppliers do have this information to hand and possible this info could be accessed and found out easily?

I replaced a whole set of bearings on my Buddy's Trek Fuel a while ago. Never attempted to do pivot bearings before. Got the codes ordered the replacements, delivered the next day and did the whole job in around two hours with D.I.Y. methods and no special drift kits, pullers, etc.

Judging by the local bike shop taking a week to do the same job with specialist tools the previous time I assumed they did it the way we did once he dropped the bike off without the aid of a database or spreadsheet?

I could be wrong and can only relate to my local LBS time scale for doing the same job.

Glad you got the info. Good to know Pal. Maybe I'll try contacting the manufacturer direct if needed in future except all my crew are on hardtails now!

My explanation was send just after your last post! Beat me to it. I'm not fast at typing especially on a mobile. Wink
