Fit a new groupset

mackeminexile

Hi, hopefully someone can help. I've been lucky enough to get a full Ultegra groupset from my brother in law for a steal. Would like to fit it myself, any advice on tools needed etc? I'm pretty handy and service my own car so relatively confident and have all the usual tools like socket sets etc. What else will I need to buy to do this? Also fitting new wheels once they arrive on Thursday. Like a kid in a sweetshop!

No special tools needed. Plenty of videos on YouTube to walk you thru the setting up of derailleur. The trickiest bit (IMO) is getting the cabling sorted (routing, etc). If you have to cut new cable outers, its best to invest in the proper side-cutters for the job, as any poorly cut ends will soon fray the inner cables and could leave you stranded.

Take your time and double check before you cut anything!

You'll need a cassette lockring tool (http://www.parktool.com/product/cassette-lockring-tool-fr-5) and chainwhip (http://www.parktool.com/product/5-to-11-speed-compatible-chain-whip-sprocket-remover-sr-11) to put the cassette on the freehub and a bottom bracket tool to install the bottom bracket and crankset (http://www.parktool.com/product/bottom-bracket-tool-bbt-9). You might also need a decent snips for cables and cable housing (http://www.parktool.com/product/professional-cable-and-housing-cutter-cn-10) and of course you'll need a decent array of allen keys and a torque wrench wouldn't hurt if you can get your hands on one, oh and don't forget your lubes and greases. There might be a few more tools that you'll need but that's what springs to mind at the moment in terms of unusual tools. I linked to park tools because they're really spiffy but you can get a cheap set of tools from the likes of halfords that should do the job.

Thanks for the replies, I'll have a look at those tools. Have the Allen keys etc, will go get grease too, any suggestions?

Grease with very useful applicator. Don't know how I lived without it

Halfords and most bike shops stock these.

Very satisfying changing out parts on a bike imho. Good luck.

I'm really looking forward to it, just a bit concerned to keep the cost down. Had a quote of €80 and another of €90 to do the build for me but I like to know how things work and it seems manageable.

Are you changing bottom bracket?

The rest is straight forward enough. Performance bike and park tools YouTube channels are very handy.

mackeminexile

on that note, is there a specific bottom bracket tool for each type? I have an FSA MegaExo Pressfit (Giant Defy 2) BB.

not changing the bracket but will need to remove and reinstall to place the crankset.

Are you sure the new crankset fits the old BB? If it does you're laughing.

mackeminexile

not sure and can't find any reliable info to be honest! As I mentioned above it's a FSA MegaExo pressfit bb and I'll be upgrading to full Ultegra compact group. Think it's the 5700 chainset. Any ideas?

It should be fine.

I hope so anyway, I'll be fitting an Ultegra 6700 crankset to the same BB next week!

Well Saturday is d day so I'll post here and let you know. New Campy Scirrocco 35mm wheels arrive tomorrow, my missus can't understand why I keep going and just looking at the bike. All excited.

I'd say that it's at best 50-50 as to whether the crank will fit your Pressfit BB! The cranks are likely to be for a typical Shimano Hollowtech BB. Just be sure to check before you start taking things apart! There may be an adaptor available if not!

mackeminexile

You have me worried now!

mackeminexile

just checked with the Giant store on the Kylemore Road. They said I'd need a press fit Shimano bb. €50 and €20 to fit it if needs be.

The FSA and Shimano BB86 pressfit BBs are supposed to be compatible, some of the FSA ones are .5mm too big for the hollow tech cranks apparently even thought they're supposed to fit. I can't figure out which FSA ones they are though

Handy video, funky house music.

Ok, so final word is that I needed a Shimano bb but not a pressfit. Its a British screw fitting. Just picked up the Ultegra BB and the tool for it in Penny Farthing. I have to say fair play to Graham in there for going through it all with me. Gonna have to get on with the first stages tonight maybe. Damn wheels haven't arrived yet though. Thanks for the vid!

If your bike takes a Pressfit BB then a Shimano Hollowtech (ie. screwfit!) one will not be compatible!

Agreed, you can't fit a screw fit BB to a bike that takes a press fit BB.

It's pressfit or nothing. Are you sure you have a pressfit BB now?

mackeminexile

Ok, so I was getting the pressfit BB from the specs on the Giant webpage. I'm not sure it was the correct model/year that I was using. I went into Penny Farthing and explained what I was doing and Graham went through it all with me and said I'd need the Shimano SMBB6700. I chose to go with the Ultegra over the 105. I'm now totally confused. I'll just have to wait till I get home and have a look I suppose.

C3PO

Well it'll be pretty obvious when you look at the bike whether it's a Pressfit or Hollotech BB - stick up a photo if you're in doubt!

will do, thanks

A hollowtech/megaexo bb will have external aluminium splined cups in between the crank arms and the frame, pressfits are basically a pair of cartridge bearings with a friction fit.

There's a third possibility that you have a press fit style BB30 with an adapter which gives it the threads of BSA, but that's a long shot. The specs on Giant's website seem to show your bike having a 68mm BSA BB, which means all you should need is a hollowtech spanner and the crank preload cap tool.

If the bearings currently in there are smooth with no creaking and the crank is compatible (if you're going from a 4500/4600/5600/5700 to a 6700), there's no need to replace the BB until the previous bearings are worn out.

mackeminexile

Ok, so all going well and able to change everything except this fella. I think I need the crank puller tool that has what looks like an Allen key coming out of a socket head?? Any ideas folks?

That looks like a BB with external bearings, so all you should need is allen keys. One for the pinch bolts (undo them a quarter to a half turn each in an alternating manner), and then another (or maybe the same one, but would doubt it) for the preloading cap/nut which you can see in the photo you attached.

All of these should unscrew anti-clockwise in a conventional manner.

It looked like an Allen key inside but the 5mm didn't feel like it was taking and I didn't want to strip it. 4mm was too small too. The pinch bolts loosen easily enough though.

Hmm, now that you mention it the preload part does look a bit worn/rounded. I think this is the installation guide for the crankset in question (based off this specs page) in which case it would be an allen key to loosen the preload. Might help if you can throw up a pic straight on with the hole in the preload cap?

mackeminexile

so the preload cap allen key hole is stripped to a fair degree. Any ideas? This isn't the first time that I've gone to upgrade something on this bike to find stripped allen bolts. The shop that sold it to me must have a heavy handed mechanic. I'll take it into my LBS if there's no hope of sorting it myself. This is getting expensive now!

That's actually a bit concerning, since the preload isn't even meant to be that tight! Just take a look at the fitting and tool that the Shimano Hollowtech cranks use, which doesn't really allow you the leverage to tighten it much, not to mention their being plastic!

I guess a lot of the question comes down to what condition you want to keep the old cranks in, but if the preload isn't in all that tight as is meant to be the case then a dremel or something might be able to notch the cap to let you slot something in to turn it. Having said that, someone did manage to round the allen bolt! LBS might be the safest bet at this point, if just in case they can come up with a simple option, or in case you might make a mistake if it gets to the point of cutting tools

mackeminexile

that was my thought. I actually wanted to sell on the FSA stuff along with the tiagra cassette, front and rear mechs, shifters etc. I'll take it tomorrow and post back tomorrow night hopefully.

mackeminexile

so the only way to get it off was to hammer a flat headed screwdriver into it. Bit annoyed as I now need to try and find one online o I can sell the set. Whoever set it up in the shop I bought it from had heavy hands, they did that to the stem face plate screws too. On the plus side, Graham from Penny Farthing did it for free for me.

Gonna finish the build tomorrow morning and hopefully get a ride in. Will post pics of the whole thing when I'm done.

Good to hear you got sorted. In the meantime, take a look at http://www.chainreactioncycles.com/ie/en/fsa-crank-bolt/rp-prod679 in case it saves you trawling fleabay

mackeminexile

finally got it all finished last night and a quick 10k to make sure it all stayed together! The front derailleur was by far the most difficult part as I realised afterwards that the 105 shifters don't have a barrel adjuster on them so the tension for the outer position had to be done by hand which was tricky!

New wheels and different casette meant I was cruising last night at 40kph comparatively easily to the stock wheels and Tiagra 12-30 cassette. Well happy, hopefully get a proper ride in tonight if the weather holds.

Definitely worth investing in the tools and time as I now have an understanding of how the bike actually works. I would say that I'll be getting a proper workshop stand though, my back was killing me by the end of it! Some pics below.

Looks good
