Advice on a bike (Felt B12)

Hi all,

I'm new here. I enjoy riding bikes, but I have very little knowledge about bike tech and performance. I have a 2013 Felt B12, having being given it by a friend last year. I rode it a few times and it felt pretty decent. My question is, are there any obvious upgrades that I could make? I guess as a secondary question, is this bike any good...and if not, should I just flog it and get something new?

I want to post a picture of it, but i'm not allowed for some reason.

That's actually a pretty solid bike if it is in good condition. Especially if you're starting out. Nothing wrong with that at all.

Biggest consideration is making it fit for you. What basebar/extensions setup is on it? Does it have all the little stack spacers with it so you can adjust it? If it does, go get a fit done on it and ride that thing.

I might say to change out the cassette to a more modern 11-28 perhaps. As that 38t inner ring might be too much depending on where you plan to ride it.

Other good thing is it doesn't have a proprietary one-off cockpit either. So if you ever wanted to upgrade the cockpit to a modern Tririg or something, you can quite easily. Then you could go 11spd at the same time if you wanted.

I'd also perhaps ditch the wheels and get something in a modern width to handle a modern 23 or 25mm tire without any aero penalty. Also your body will thank you versus riding small tires. Given it's a 2013, I bet it was a time still for 19mm to 21mm tires. Which aren't much fun.

Also, go with a modern split nose saddle. Your bum will thank you for that.

Good bike, keep it, ride it. My first TT bike that I rode for a few years was a 2008 Felt DA. I kept the frameset in the shed just for memories sake.

Thanks for taking the time to reply. I'll take it to the bike shop and mention the things you have mentioned (so I look a bit like what i'm talking about) and see what they say. Will also get a bike fit done.

Cheers!

I Googled “2013 Felt B12” and got the below picture. You didn’t specifically say in your OP that you intend to use the bike for triathlon. Seems like a good bike for it if you are. Anyway…just want to point out that it ‘looks’ like that aero seat post on Felt is reversible…like the one on my Specialized Venge. In the pic, it is set up for triathlon geometry…a more forward position. But, it can be turned around (and the seat turned around) so that it’s farther aft to give you more of a road geometry. — Dan

Get a bike fit (even online should give you some ballpark numbers) and ride it.
So, first: make sure it fits.

See what needs to be replaced (rear cassettes are easy to do it yourself with some tools), replace them if needed. Get yourself some tools and learn from YT videos how and what.

You will ride "always" in aero position. While that could work for you, I'd advise to buy a second, used, bicycle for not too much. Use that for hill training and all that.

But beautiful bike. I'd love to have it nothing wrong with it. I ride a Fuji Sportif with a different saddlestem and tribar setup. This would be a big step up!

The only suggestion I have regarding a Felt of those year is to check the hub/sprocket for being tight. They shipped a whole lot of these very loose and it was an easy thing to miss during assy.
Aside from that aspect I had a Felt F series that I liked a WHOLE lot for the price. Some user error concerning interpretation of proper torque on the stem led to my damaging the fork steerer and was very unhappy with the resolution, so I sold it.
