Product Review- 2011 Felt F1 with Di2- Felony is born


George “Red-Eyed Vireo” Vargas climbing Montezuma Grade (12 mile 3,400 gain) from Borrego Springs to Ranchita in the desert climate of California east of San Diego

My 2011 Felt F1 has taken me to great heights including a Personal Record in the 2011 Breathless Agony climbing century with a new PR of 5 hours 24 minutes.

It is with great pleasure that I write the review on the 2011 Felt F1.  Last year I rode the 2010 F2 with Di2.  As the 2010 season came to a close I was very excited to ride the redesigned 2011 Felt F1.  All I needed was a frameset, so I could use my Shimano Dura-Ace Di2 components, SRM 7900 wireless crankset powermeter, Shimano Dura-Ace wheels, cockpit, saddle and Dura-Ace pedals.

Below you will find the breakdown of the components I used including their weight — claimed versus actual.

Felt Bicycles is located in Irvine California and has their warehouse in Ontario, CA

Felt Bicycles does a very good job packing and protecting the precious cargo within.

The 2011 Felt F1 54cm now has a 73.5 degree seat tube angle.  2010 had a 74.5 degree seat tube angle.  For the 2010 season I rode a 56cm F2 so that I could use the 73.5 degree seat tube angle. Personally, I prefer 73 degree seat tube angle.

2011 Felt F-Series bicycles now come with an all carbon BB30 bottom bracket shell.   The bottom bracket is manufactured with a shoulder.  The first hurdle I encountered during assembly was not being able to use the Shimano external cup bottom bracket.  I use a SRM Shimano 7900 Dura-Ace wireless crankset power meter.  The Shimano crankset is a standard 24mm crank  So what were my options?

1.  FSA Bottom Bracket aluminum sleeve

2.  Felt supplied bottom bracket adapter

3. BH bearings

I chose option #3

Option #1- seemed somewhat permanent to me.  You have to press in the sleeve that reduces the 30mm down to 24mm.  I figured in an all carbon bottom bracket shell if I ever decided to take the sleeve back out I might damage the shell.  If you decide to use it the external bottom bracket bearing cups just screw in like a normal bottom bracket and the 24mm crankset installation is uneventful.

Option #2 – I remembered having issues on another customer’s bike assembly and just passed on it.

Option #3 – I remembered having a positive experience on several other BB30 bikes including the Felt F1 and so I went with it.

A word on BB30– I know all the technical reasons and merits for such a new standard.  But in my experience, in a shop environment, I have not seen where BB30 is that much greater than the 24mm standard.  Time and time again bikes come in with creaky bottom brackets and 95% of the time it’s a BB30 system.  Cannondale pioneered the standard and they make a REALLY light crankset to go with their BB30 bottom bracket.

Is having the crankarms closer to the frame (Q-factor) necessary in all applications?  Add to it the lack of durability (bearings aren’t sealed properly) and you end up with a system that requires a lot more maintenance.  I have had Shimano Dura-Ace external bearing cups on some of my bikes for years and years and thousands of miles and never had to replace one.  When I asked the road product manager why BB30 he responded “to have more crankset options”  Agreed you now have more options but I personally don’t think it was necessary.

I digress, option #3, requires you to mill down 3mm so that the cups can be fully inserted against the shoulder in the all carbon bottom bracket shell.

After being milled down notice the stock and milled 3mm

Shimano Dura-Ace 7900 pedals claimed 248g actual weight 247g

Shimano Yumeya Chain

Shimano Yumeya Chain

TiN (Titanium Nitride) plated inner links which improves stretch durability by 18% while increasing oil retention, which also indirectly increases chain life. Thus, for a little bit more money, you get a longer lasting chain that rides quieter and arguably looks much better. The 7900 Yumeya chain still features Shimano’s directional outer links for better shifting all around, and remains super light with it’s hollow pins and hollow inner links.

Features

  • 7900 Yumeya chain weighs 258 grams
  • 18% increased chain durability
  • Increased oil retention
  • TiN plated inner links
  • Hollow Pins
  • Hollow inner links
  • Profiled outer chain links for smoother, quieter shifts

Complete bike weight with Shimano Dura-Ace C24 carbon clincher training wheels.  You can always make the bike lighter.  I have a full Dura-Ace group and we all know that Shimano is more interested in high quality, dependability, and durability than being the lightest in the industry.  Being an Ultra cyclist, I really appreciate Shimano’s conservative approach to design.  I do lots of miles and many times I’m out in the boonies or on closed roads.  I build my bikes with components I can trust.

The Ride

Ok so now that we have covered all the technology and weights and measures how does the bike ride?  It rides like a full-on race bike!  Felt Bicycles did a fantastic job in making that happen.

I built the bike after work and just HAD to get out for a test ride that evening.  I chose a flat 20 mile ride along Pacific Coast Highway from Newport Beach to and through Huntington Beach.  The usually annoying traffic signals provided me with the opportunity to perform numerous standing starts from a trackstand.  I was surprised the first time I really stomped on the pedals and looked down and saw that my max wattage was over 1,000 watts.  I was like “wait what the…”  So at the next traffic signal I slowed, did my trackstand and BAM! stomped on the pedals and again another 1,000 watt effort.

Alright this is quite unusual for a guy like me.  If you follow my blog you know that I am an Ultra Cyclist and rarely does an ultra race (200miler and above) come down to a sprint finish.  I don’t train to have a massive sprint or anything even remotely similar.  I train to have endurance and tempo forever as my friends like to say.  My first thought was that my SRM must be reading high so I pulled over and redid the zero-offset.  But that didn’t matter because I hit over 1,000 watts on two more occasions.

I started making some deductions…if the bike is light and the bike is stiff then it must climb well 😀  that would remain to be discovered since it was late in the day and no time to hit any climbs.  After the initial excitement in discovering I actually had a sprint 🙂 attributed to the awesome bottom bracket stiffness I began to focus more on the Felt F1’s road manners i.e. ride quality.  That’s when I realized the front-end was a little too stiff for my liking.  The new frame has a 1.5″ bottom bearing in the headset with a tapered headtube and tapered fork to match.  I think it might be too stiff for the recreational rider but then this bike wasn’t really made for that rider was it?

When  I spoke to the Felt road product manager he acknowledged that the front end could use a little more refinement.  He mentioned to me that a new fork is in the works and will help with the front end ride quality.

Aside from the front end this bike is loads of fun on ascents and descents.  Since my first test ride on this bike in May I have done several thousand miles and I am thoroughly enjoying it.

Here are only a few of the epic rides I have done with my 2011 Felt F1:

Breathless Agony Climbing Century– May 5- 112 miles (70 miles with 11,000 feet of climbing)

Newport Beach to Dawson Saddle-  May 14–168 miles with 11,300 feet of climbing

Angeles Crest Highway— June 24– 100 miles 12,000 feet of climbing

Lake Henshaw Climbing Camp– July 11 100 miles 10,200 feet of climbing

In addition to these epic solo climbing rides I have also done many club rides which test not only my abilities as a rider to stay in the pack but the handling characteristics of the bike underneath me.  The Felt F1 is in my opinion a full-on race bike!! It is stiff it is light and it handles extremely well.  It needs just a few tweaks to provide it with a little more finesse to enter the world of the “superbikes”.

I would rate this frame a 4.7 on my scale of 1-5, 5 being perfect.

  1. Can you tell me how you attached the SRM Magnet on your new F!? I have just got a di2 equipped F1 and of course it doesn’t have a cable feed on the underside of the BB shell. Seeing how you attached yours would be very much appreciated.

    Cheers

    • Chris,

      Thank you for reading my blog and taking the time to make a comment.

      How did you come to my blog anyway?

      Refresh the blog post and you will see I use a very low budget solution– black electrical tape. Because I usually trade out my frames every year I don’t like to do anything permanent to them. Believe it or not it holds very well. I check it every time that I clean my bike and/or lube my chain– at least weekly. I had multiple strips on but I took them off so that I could take a picture for you.

      Cheers,

  2. Eric…Nice write up. Tell me what is the difference between a Shimano Yumeya Chain and Dura Ace chain? Will the Yumeya work with Sram? Thanks again.

    • Mike,

      Thank you for your continued support in reading my blog and taking time to post a comment.

      Here is more information on the Yumeya chain.

  3. George,

    Outstanding write-up and overview! I bought a late year 2011 Felt F1 frame recently and, like you, intend to build it out with Shimano Di2. It appears as though you were able to integrate an internal junction box into the access port at the bottom of the frame. Is that the case, and did you have to make any modifications to the junction box? Finally, like you, I plan to run a Shimano crankset (likely an SRM). Have you ever looked at or used the HSC BB30 Ceramic Adapter Bottom Bracket (sold at Fairwheel Bikes)? I intend to use this as a solution to (or avoidance of) the issues that seem to plague BB30 setups. Thanks again for an outstanding review!

    • Paul,

      Thank you for reading my blog. I did not make any modifications to the frame or the junction box. I have not looked into the HSC BB. I’m not a fan of BB30. It is plagued with many issues. In the shop we see a lot of customers coming in with creaky bottom brackets. Mostly they are dirty or the BB30 bearings just don’t last. Use a standard outboard bearing 7800 or 7900 BB from Shimano and it will give you tens of thousands of trouble-free miles. But then that means using BB30 adapters to bring it back to the Shimano 24mm standard and that means adding weight to these super light frames urg!!

      Stay tuned I am expecting the arrival of my new bike…a Cannondale Evo! I’m so excited to ride something even lighter and more comfortable than the Felt F1 that I rode last year.

      Cheers,
      george

  4. George,

    GREAT right up! Enjoyed reading your thoughts. I wondered if you could compare the 2010 Felt you were riding against your thoughts on the new 2011. Could you go wrong with either bike, or is the 2011 such an upgrade that one shouldn’t even consider the 2010 model?

    Thanks,

    Chris

  5. George,

    Thanks for the great blog. It is inspiring.
    Of note, I am 6′ 3″ – 185-190 lbs and ride the 2011 F1 in a size 61cm with exactly the same components and wheels (except using an FSA SRM with the new BB30 adapter cups) Perhaps due to the difference in frame size and or my heavier weight, I LOVE the front end. I also find the the bike is very compliant vertically and in fact rides a lot smoother than my “non-race century plush” carbon/ti Serotta. On another note, I choose the F1 as it has the longest top tube relative to seat tube of any of the production carbon bikes. I have a long torso and arms and need as long as reach as possible. The F1 fills this niche.

    Btw – have you experimented with different tubeless tires? I am now trying the Hutchinson “intensive” vs the “Fusion 3.”

    • Hello John,

      Thank you for reading my blog and taking the time to post a comment.

      I am glad you have found the right bike for you. My comments on the Felt F1 are merely from an Ultra Cyclist perspective. I actually loved the Felt F1 when I was riding in spirited groups. Fast club rides and the local “Saturday World Championship” were a lot of fun on the Felt F1. The front end was firmly planted in switch-back roads and the sprint to then county line! It’s a great bike.

      I have only ridden the Fusion 3’s. What is your experience thus far with the intensive tires?

  7. Hi!
    Thanks for the article. I currently ride a 2013 CAAD10 2 SRAM Force, 6011 aluminum race bike. I’m looking at buying a near mint 2011 F1.
    Your thoughts since writing your review? Thanks again!
    Bret

    • Hello Bret-

      Thank You for reading my blog and taking the time to make a comment. Looking back the Felt F1 it was pretty close to the harshest riding carbon bike I have ever owned! In speaking to the product manager from Felt he thought it was more related to the fork and tapered front end. However, the whole bike was too harsh for my liking. If you look through my blog you will notice that I am an endurance cyclist so comfort is very important to me. I raced on the Felt all year because it was a sponsorship gig however I prefer steel frames more than anything else for long-distance riding.

      Since the writing of this review I opened my own bike shop in January 2013. I now carry and ride the brands that I prefer. I sell carbon bikes for many manufacturers.

      If you wish we can talk off-line so I can get you into something more comfortable in the Felt F1. You can contact me at revcycling@gmail.com

      Cheers,
      George
