My First Build - Specialized Allez - Assistance Required

Postby Defy The Odds » Wed Oct 03, 2018 5:41 pm

So after 4 years on my Giant Defy Comp, I decided I wanted a nice new "fair weather" bike.

I looked at a few options and decided to build a bike from frameset onwards.

I have always taken a liking to the Specialized Allez and after some reviews, bit the bullet and purchased a 2019 Allez Sprint DSW frame.

Now, I've never built up a bike before, only done basic maintenance so this is all new to me.

I'm in the process of piecing together 2nd Ultegra 6800 bits and wanted to know specifically about the crankset.

As I said I am not well versed but always willing to have a go. Do the Ultegra cranks fit straight on or do I need some sort of "kit" for the OSBB (which I believe is BB30 standard) bottom bracket housing and then fit the 24mm Shimano crankset?

If I do the adapter route, can someone point me in the right direction in terms of correct sizing/standard required and so on (eg I have read to use the praxis works or wheels manufacturing adapter and then purchase a crankset which adopts the BB386 or GXP standard).

If anyone has built up one of these bikes before, your assistance would be greatly appreciated.

Thank you kindly in advance !

Look for Wheels Mfg BB30 to 24mm converter, or others on the market, which are simply Delrin spacers that press into your current bearings (if you wish to retain the BB30 (6806) BB bearings). You could also opt for a Wheels Mfg, or other BB30 to 24mm full converter, which has you removing your BB30 bearings and pressing this converter into the BB shell, which converts it to being suitable for 24mm Shimano cranksets - plenty of options, just googlefu it...

My experience with bb adapters is don't bother and even moreso in aluminium frames. The wheels mfg bb kits may cost a bit more but they are worth every cent. Good quality bb bearings are an under-rated component of a bicycle.

Good frame choice, I'm waiting for them to bring out the right colour scheme for me before I add another horse to the stable.

If I buy something like Rotor cranksets for example, I believe you can get these to fit BB30. Would it creak? Would it still be worth getting the wheels mfg kit and running a 24mm rotor crank spindle?

Also, is it better to get a complete replacement bottom bracket such as this:

Thank you again this is a big step for me (I can hear some of you laughing at me as you read this)

30mm cranks will fit straight in, you will only need a replacement bb to run 24 or 22mm cranks. The bb that Specialized include with the frame is not a great one though and creaking is more likely in carbon frames rather than aluminium. The problem with a bearing that spins a bit rough in aluminium is it tends to vibrate the frame a bit and be a bit noisy all the time rather than creak. You probably just need to decide which brand of cranks you want, do you want full matching groupset or do you want a power meter and then get the bb to suit whatever choice you make.

So here is what I am thinking, go easy on me !

I would prefer to build up the bike with SRAM but since you can't buy full groupsets here in AUS, I would have to source each part on its own or 2nd hand. Even second hand, it seems expensive.

eBay seem to have complete 105 R7000 groupsets for about $600-700 delivered (including cassette and cranks, etc) - this is for 50/34 chainrings and 11-30 cassette as my preferred setup.


I was thinking of getting a complete groupset kit, press fit. Then purchase something like this:


https://www.google.com.au/url?sa=t&rct= ... BCNUusVpLL

This should make it all work, correct?

The other thing I was considering and wanted opinions on, is that the R7000 has options for an 11-30 cassette. I currently have a Defy which runs a 50/34 and 11-28 cassette and I find on some steep climbs that I would love to have an extra bailout gear. Has anyone used this combo before and how does it compare with an 11-28?
My thinking was that it wouldn't be as big a jump each gear as say an 11-32... ???


So my setup would be something like this (to summarise):


Shimano 105 R7000

50/34 Chainrings
11-30 Cassette
Short cage Derailleur
170mm cranks
Pressfit bottom bracket
Rotor BB30-24mm bottom bracket (in order to fit the Shimano cranks straight in and avoid the annoying vibrations/creaking that will eventually plague it in future)


thoughts and guidance welcomed :-)

Go the Shimano over SRAM. Much easier and cheaper to repair/replace.

Use one of the screw-together bottom bracket adaptors (Praxis Works make a particularly well-rated one, probably mentioned earlier in the thread). If you're going to use a crank designed for 90mm total BB width (threaded shell with outboard bearings or 86mm press-fit), use an appropriate bottom bracket system to make the most of it and support the crank properly. Narrow-spaced bearingsinside a 68mm shell (BB30/OSBB) with spaced-out long spindle overhangs will reveal any shortcomings in the frame tolerance, and contrary to the belief expressed above, aluminium frames DO creak! A screw-together adaptor will give you proper bearing placement for the crank, with the extra security of the two parts supporting each other in the frame.
I had a thought, but it got run over as it crossed my mind.

Duck, would something like this suffice?

http://www.chainreactioncycles.com/mobi ... prod130495

Also, if I did purchase and install this can i then use any Shimano-rated crankset (ie 24mm) into it or do I need a specific length spindle?

Apologies for the questions if they seem silly

That'd do pretty well. Basically any Shimano, FSA or Rotor road crank with 24mm spindle will fit. Triples have a longer spindle, but include the necesary spacers with the crank, all others are the same length. MTB cranks also have a longer spindle to suit the wider frames.

I used a Praxis Works BB30 adaptor to fit Shimano CX cranks to my CAADX years ago. Never had a problem with it.

I got it secondhand off either this forum or the other one.

I have 4 mostly black bikes, 2 are all black and 2 are black and white, it seemed to be rather difficult to buy anything other colour.

So I have been contemplating groupset build as i have purchased the wheels. I ended up getting a 2nd hand set of Roval CLX 60's with CeramicSpeed hubs.

Question regarding the groupset is, I have the opportunity to purchase DuraAce 9000 brakeset and shifters and looking to get either 105 R7000 or Ultegra R8000 FD, RD, Cassette and a KMC SL chain (already purchased a Vision TTrimax Chainset).

Is it worth getting the 2nd hand 9000 DuraAce shifters and brakeset and mixing it with the new R7000 or R8000 or just go complete new R7000 (Ultegra R8000 is out of my budget)?

Also, will the DuraAce calipers clear 28c tyres?

9000 will struggle with 28's. They may fit depending on rim width but the clearance will be minimal, like 1-2 mm, which is not really enough. Why do want to run 28's?

I was considering 28s to dampen out some of the road buzz. Being an aluminium bike every bit of compliance helps

Is there any reason why 28s wouldnt be a good idea on the Allez sprint ?

I'd say 25s on newer wider rims run at slightly lower pressures would be optimal, especially if 28s are too tight a fit on the frame.

Rim brake clearance, even with 28s if they fit the frame, would be OK with newer Ultegra brakes.....I think?

I used 28mm (actually 30mm once inflated) tyres with Ulegra 6700 until recently. They were difficult to get through the calipers but no problem once the wheels are installed. You can always inflate them after installing on the bike. So don't let that stop you.

I did upgrade the brakes to Ultegra R8000 and they do fit through fully inflated now which is nice.

You have been lucky but the riders I know who have 28mm tyres have next to no clearance and frequently have small stones trapped between the tyre and the brake calipers. In one case the stone wore through the tyre and punctured the tube.

This happened to me once on an old roadie I squeezed 28s onto, compounded by having to ride a section of recently re-sealed mountain road - so add some still-gooey bitumen to the mix ! :roll:
