It's time for a new road bike, my '99 Cannondale is getting a bit tired. I'd really like nice racy wispy road bike but I have no serious aspirations to road race beyond some fondos, centuries and group rides. The roads around here aren't exactly smooth and my road rides frequently use the local rail trail to string routes together. It can be done but I don't think a wispy road bike is the best tool the type of riding I do, hence the Diverge.

I'm thinking about the carbon comp model. Any of you guys own one? My LBS says they are selling pretty well and what limited reviews there are seem very positive. I was pretty set on the Cannondale Synapse carbon Ultegra disc and while a capable bike I think the Spesh might be a better choice for my riding conditions.

I have built a few in the shop and the owner is riding one, he is very impressed with how smooth it is, and the hydraulic breaks work fantastically. They are quite heavy, I guess due to the burly wheels, Hydro disc break and bigger tyres but I'm sure one could be put on a diet fairly easily.

The weight is a bit of a concern. Heavy for a road bike or just heavy in general? I think the carbon comp is right around 20 lbs. Don't really want to have to swap parts on a bike at that price range.

Heavy for a road bike, not that heavy really and to build a bike that will take the abuse and be comfortable is always going to cost you either weight or durability.

Diverge Comp Carbon (Shimano 105)

Just bought one, still tinkering with it, but stoked so far. For me the things that stand out most are the sweet ride and the wonderful hydraulic disc brakes as pointed out by Tom. The 32mm Roubaix tires contribute to a nice ride, but the frame and Cobl-Goblr seat post eat up bumps much better than I expected. Rides smoother than my carbon Crux with 40mm tires. Also seems more stable than the Crux likely due to the low bottom bracket. The Shimano 685 brakes are smooth and strong with good feel - on a par with top mtb brakes and much better than any mechanical or mechanical/hydraulic disc brakes I’ve tried. They add a lot of confidence at high speeds and in sketchy/rough conditions.

Already “personalizing” it: wider Salsa Cowbell handlebars, mtb crankset with smaller chainring options, and Easton EC70 wheels. The rear wheel switch was a bit tricky since the Eastons don’t use the Specialized SCS offset hub and the cassette ends up 2mm further out. Fitting required replacing the derailleur hanger, axle end caps, and adaptors with those supplied for a QR axle, but I’m experimenting with an mtb hanger to accommodate the 12mm thru axle. The good news is that wheels can be swapped easily, requiring only a minor rd adjustment but no brake caliper adjustment (surprise!).

Here are some pics (wish Specialized would grow out of it’s “Henry Ford any color as long as it’s black” phase :madman:)

First, tire fitment:

This shows what the rear looks like with a Conti SpeedRide tire measuring 40mm wide on the OEM Axis wheels -- too tight for comfort. Fork is a bit better, but still too tight.




Here’s a Conti Cyclocross tire measuring 36mm wide on the OEM Axis wheels - plenty of clearance.




Here’s the full monty with the Easton wheels and Roubaix tires. The 54cm bike weighs 21.0 lbs almost ready to ride as shown with pedals, pump, bottle cages, two small bags with tube, tire levers, patch kit, pressure gauge, chapstick and a Goo packet. (it’s about 19.5 lb nekid, without pedals and accessories)




Time to get out and ride! :cool:

It shpuld have come with a different hanger for running a standard 135 QR MTB hub in the box I think.

Correct, thanks Tom, I could have made that clearer. I did use the non-offset QR hanger and frame adaptors for a QR axle provided by Spesh. The adaptors just make it a bit fiddly to R&R the wheel compared to the simple thru axle. I'd prefer to use the 12mm thru axle, but I need a rd hanger that will accept it but without the 2mm inward offset like the OEM 12mm hanger designed to work with the SCS Axis wheels.

I like the Diverge thru axles that use a 5mm hex key to tighten/loosen. Very clean without levers protruding and easy to get consistent tightening torque.

I have a Diverge Expert on the way very soon. Really looking forward to a combo mtb/road/gravel ride option that I can do darn near from my house.

Any idea abt additional TA 135x12 hub that will work on this bicycle. Royal wheels are to expensive for me.
Maybe there is some chance to adjust in some way Dt240 hub? That is completely crazy for such a company like spec to release nice bike without any option to get additional not expensive wheels.

You can convert most DT swiss hubs to 135 x 12, as well as Hope hubs, SRAM hubs (their X0 hub is actually very nice) and many others, it is a size that has been used in MTB previously so there are options.

As I know it is a problem because specialized SCS hub is moved inwards 2,5 mm at the drive side - placing cassette on the standard hub cause rubbing of the smaller cog on the chain stay as it is mentioned by other owners

The shade tree mechanic’s solution to the Diverge rear derailleur hanger hangup

The mrs and I each recently bought Diverge Comp Carbon bikes that we’ve been personalizing, and like others we wanted to use a second wheelset with standard 135mm spacing. We both had Easton EC70 wheels (carbon rims, ~1500g set) that we wanted to be able to use. The front wheels with 15mm thru axles mounted up fine. However, the rear wheels with 12mm thru axles presented the much maligned “SCS hangup” - the cassette lockring hit the inward-offset rear derailleur hanger. :bluefrown:

“Factory Solution”

First option was to replace the rd hanger with the supplied QR hanger which does not have the SCS offset. This worked fine, but the QR axle required using fiddly adaptors on both dropouts. It seemed a shame not to employ the 12mm thru axle the frame and wheels for designed to take advantage of.

“Shade Tree Solution”

The rear derailleur hanger is an inexpensive and easily replaceable part, so break out the power tools! The SCS hanger is fairly burly, like a mountain bike hanger, and seemed to be a good candidate for a diet. Coarse measurements suggested that taking a mm or so off the inner face could provide clearance for the lockring, and the hanger was introduced to the power sanding wheel. Neither the hanger mounting screw nor the rd mounting screw engaged all of the threads on the hanger so there did not seem to be problem removing material on the inside face. Just enough was ground off to leave a small lip protruding inside the frame as a protective measure. The lower part of the hanger was sanded down to be flush with the rd mounting screw to give maximum chain clearance.




It worked, just barely. There is probably only ~0.2mm clearance between the cassette lockring and the rd hanger and even less, perhaps 0.1mm, between the chain on cog 1 and lower part of the hanger and the rd mounting screw.





The tolerances are so close that I’m not sure it will work on other bikes or wheelsets. Both of our frames, 49cm and 54cm, turned out exactly the same so there is hope if other manufacturer’s wheels and end cap adaptors are similar to the Eastons.

Nice solution to be checked as you mentioned with other hubs.
Assume there is no any problems with shifting because of the chainline.
Did you ground off all that can grounded or there is still any area for further dieting?

re hanger hack

No discenrable problems with chainline, tostos. I'm not even sure why folks are concerned about small changes. How much of the time are you in the gear that gives a perfectly straight chainline? Cog spacing on an 11 speed cassette is ~4mm, so a 2.5mm off set corresponds to less than a cog change. Fortunately, modern chains are flexible enough to handle cross-overs (~20mm fully crossed).

No need to grind more off the top of the hanger since the lock ring is fixed and does not make contact. Leaving a bit protruding inside the dropouts also offers some degree of frame protection. The chain is very close to the lower part of the hanger, so a bit more could be ground off if there's evidence of chain rub (none so far). This would require grinding a smidge off the derailleur mounting screw as well since I already ground the hanger flush with the end of the screw.

Spacing issues

Hi once more. I did some measures and found that there is 2,5mm space (SCS Diverge hub) between smallest cog (casstette locking screw) and chainstay even if we assume the hanger will be grounf off according to your instruction - see my picture.
Because I have to risk and buy new 135x12 mm DT hub please advise if to do it? Possible threat is that moved cassette outward by 2,5 mm will rub the chainstay.

Could you take following measures and post them:
- distance between smallect cog (cassette locking screw) on SCS wheel and chainstay and
- distance between smallect cog (cassette locking screw) on your new wheel and chainstay?


best regards
Tom

Tom,
This is unrelated to the wheel issue, but looks like you are running a rear rack on your diverge. If so, don't suppose you could post another picture or two of it and let me know what brand it is?

Thanks
Justin

Hi Justin, as i know that is the issue related with hub that is by Specialized - different spacing:)

As far as my rack is concerned I will post pictures on Saturday. It is really minimalist and fit perfectly this bicycle.

Hi, can not post a photo of rack at the moment. But please find the model I have - it is Tubus fly evo - very slim and would say minimalist - perfect for my Ortlieb panniers.

Soon will try to place pictures.

By the way can anyone have new ideas about rear hub that can be used on diverge?
