Around 130 miles later...

So I've gotten two good long rides on the new bike.  I'm not even going to pretend like I'm qualified to give a review about the nuances of performance, but here's what I can say with confidence.

  • It's light.  I don't know exactly, but I'm guessing I've got 16lb-ish build here.  I feel, and probably am, faster on this bike.
  • The front end is noticeably lighter, and I suspect it's because I've never had a full carbon fork. Not a bad thing, however.  
  • The bike has a very solid feel.  No rattles or creaks or the incidental sounds here and there that I've grown accustomed to from my CAAD9 and cross bike.  
  • The SRAM Force group performs like gangbusters.  Significant improvement over SRAM Rival. 
I'm very pleased with this project.  I wouldn't even hesitate to order another frame/fork from this ebay merchant.

build complete!

Wow.  So... I'm done.

The worst part of the build came after the last post, and that was installing the chain.  For some reason, the master link was not cooperating, and I could not get it to lock into place.  It would get half-way, and not go further.  Thankfully, the Park MLP-1 pliers ($10 on ebay) were a lifesaver.

I pulled a master link off an old chain (an 1090), but that also wouldn't go on, which lead me to believe it was the adjacent pins that were causing problems.  So after working the pins back and forth, along with some prolink lube, my next attempt with the new link worked, and just a little pedal pressure was all it took to snap into place.  So make sure the ping holding onto the master link have enough room to actually hold onto the master link!

Last night, it tool me a little over 2 hours to cable it all up, dial in the shifting, wrap the bars and tighten everything down.  I feel finally I have a good understanding of how the limit screws work, and when I installed the cabling, with a minimum amount of tightening from the barrel adjusters, everything just worked.   I also highly recommend this torque wrench, the "1/4 DR 20-200IN/LB TORQUE WRENCH MICROMETER ADJUSTABLE"  (catchy).  I got it from someone (optioneparts) on ebay for $22.50.

Already had a set of allen wrench that use 3/8" drive, so a little conversion chuck at the hardware store put this guy into action.  There's actually a Newton-Meter scale written on the wrench, so you don't need that paper.   4 NM agreed exactly with my little Ritchey carbon torque key, so had no reservation for using it elsewhere.  Brakes got 2 NM, seat post 8 NM, derailleurs got 6 NM each, seat locked down at 10 NM, stem and bars at 4 NM, pedals around 20 NM.  I was very careful with the front der clamp, and I doubt there's even 1 NM holding the guy there, but it hasn't slipped. Truthfully there isn't enough leverage to really get on a BB cup, and the necessary torque for those cups are right at the limit of this wrench, so I'm not so sure I would trust the accuracy.

So even though my senses urged me to do a short local ride for the first ride, I hopped on this AM and rode it 20 miles to work.  It was fantastic.  I definitely notice the lightness of the bike, and finally think I understand what people talk about when they call a carbon frame "compliant."  I have to do a little fine-tuning on the front der, but all and all, things came together very nicely.  No rattling or creaking from the components.  Also, this bike is fast.

I haven't had the heart to spoil the look with a saddle bag, and I recently found a little carbon pump at the port ride (hey, I posted to the facebook page, but no one came forward to claim it...), which I may use, but for this ride I just stuffed a tube, a CO2 canister and that little pump in my jersey pocket. I'm not even sure I want a speedometer on this guy.

It's coming together

I had Dennis Stone cut the fork today and dig through his parts bin for some barrel adjusters. I ended up using an FSA compression plug which first sits snugly in the fork tube, then the cap screws down, gently squeezing the headset together. I think it's a better design than the plug the headset came with, which just expands as you screw it down.


The headset that came with the bike came with a plug doesn't have any capability to pull things together -- looks like this, actually, and isn't a two-piece apparatus.  

So far I really haven't had any build problems.  The drive-side BB was a little tighter than the left, and one of the barrel adjuster was dead-set on not cooperating, but screwed in eventually.  Obviously, lots still to do, but in a way I feel the hard stuff is behind me.

hammer down, fork race

I had my favorite LBS (Stone's in Alameda) pound down the fork race for the headset this morning.  I saw some DIY videos on youtube last night, but they made me feel queasy. To be honest, I was slightly hesitant about bringing in some generic fork to that shop, because (1) let's face it, I paid a 1/4 of what it would have cost there and (2) that shop is All About Steel.  But Dennis (owner) was impressed with the fork, and once he picked it said, "oh, a true temper fork...  wait... no... well, they look identical.  Hard to say, they all come from only a few factories."  Anyway, he got to pounding in the back room.  It was a tight fit, and I'm a touch skeptical just how well the bearings are going to sit...  I've cleaned an integrated headset on two other bikes, and I don't know, they just seemed more secure.  Maybe once the thing gets tightened down it'll be fine.

He also convinced me that I don't want to chop off a carbon steer tube myself, so I'll be going back.  Stone's Cyclery is a great shop, and while I did get most everything for this new bike off Ebay or online merchants, I'm happy to spend locally on accessories and miscellaneous bits whenever I can.

All the fixin's

And what you see are all the components that make up a bike! My torque wrench is ready, and Phil's grease will go where it needs to go. I have a master wrencher on retainer, and I'm sure he's going to love the email which starts off, "Okay Ant, so I took the hack saw to the carbon steer tube and...."

Lucky me, rainy weekend coming up.

last parts arrive!

Got the last shipment of parts today at work!  After very positive results with SRAM on my cross bike, I've "upgraded" my Dura-Ace 7800 shifters and rear derailleur on my CAAD 9 with SRAM Rival, and couldn't be more happy.  With Happy Fun Bike however, I decided to take it up a notch and give Force a try.  So aside from a Rival front derailleur, I'll have a complete Force group.  I decided to go with GVH Bikes due to the low prices, being able to choose the components exactly, and team mate recommendation.  It was extremely easy ordering from Tom @ GVH bikes, rounding out what has been a very painless process of collecting all the parts together.

- Force 53/39 Crankset with GXP bottom bracket.
- Force rear derailleur.
- Force shifters.
- 1090-R SRAM chain
