With the help of Bike Fitting, you’ll be able to find the right fit for your frame size, style of riding, and your particular dimensions. Here ya’ go…..the location for everything fit related.

6'4 rider on a 54cm frame

Hey guys! So I just bought a brand new 2020 Specialized S-Works Venge Disc Road Bike 54cm Carbon SRAM Red eTap AXS 12s for a $800 from a lady who's bicyclist husband recently passed away. I'm 6'4, I know 54cm is way too small for me but I couldn't pass up the opportunity to buy a ~$10,000 bike for a great price. I've talked to some people and they said that I should be able to use it with some minor adjustments. Should I try to sell it and get a better fitting bike or try and make it work?

Yes, it's likely way too small. Sell it and get a bike that fits.

Not a prayer it will fit you. Cross your fingers and try to move it along.

I'm 5'10" and your 54cm bike is too small for me. Sell it.

Personally, I'd sell the bike to someone who could ride it and split the profit with the widow. You kind of held her up at $800. I hope you at least wore a mask.

Without knowing anything about your knowledge of cycling, especially as to how it pertains to your facility in fitting into a racing bike, it is not inconceivable that you could fit a 54 size frame. Perhaps you’ve developed a fit and position along with a pedal stroke that duplicates
some of how it is done in the pro peloton. In which case riding a 54 won’t be a problem.

Also, as for example with Colnago where their size 54 sloping top tube bike is the equivalent of a size 58 traditional frame bike. Dunno anything about Spesh and how they size. So this frame might not be so far off from what the OP can actually fit into and use. Size by seat tube as a number to label a size doesn’t mean much when top tube and head tube are the drivers in fitting a bike.

So whether to sell it and get a better fitting bike or try and make it work? The answer is: It depends.

I made a kid's bike fit me by bending back the seatpost, spring setback, and slamming a thick space shuttle foam on the saddle. Virtually added 4 inches to the top tube length and raised the saddle top to the correct height.

Actually, you probably can. Conventional sizing would put you on a 58cm frame, which is two sizes up. The reach on a 58 size Venge is 405mm; on the 54 size it's 387mm. That's a difference of only 18mm in reach, or a bit less than the difference between a, let's say, 11cm stem on one and a 13cm stem on the other (which you'll probably need).

You will be a hell of a lot lower on the 54cm frame then you'd be on a 58cm frame, though, by 4.7 cm. That's why pros use smaller bikes; the shorter headtubes mean they can get really low. The big question is if that's going to be tolerable for you; I'm 178cm tall (that's just a bit over 5'10") and ride a 53cm sized frame (which has the reach of Venge's 52cm model, and stack of it's 54cm model), and riding it with a stem slammed all the way down is pretty much on the edge of what's comfortable for me.

If you can get on with being really low on the front end, the smaller bike (with a long stem) is probably going to fit fine.

Hey, to the Original Poster, ask the clown posters (who say you can make it fit) which traveling circus is hiring?

I'd harvest-strip the components off that, , then buy a New* Bigger bare frame & fork of the better size for your height ,
and put those components on it, and then re sell the 54..

* Just say no to used carbon frames & forks..

A 58 might be pushing it. I'm 6'5 and I'd consider even the 61 venge to be on the small side on account of its stack being so low. With a stack of 602mm I'd be running around 15cm of saddle to bar drop and with the 580mm of the 58 it'd be 17cm. With a 54 it'd be a ridiculous 22cm.

With the seatpost length of the 54 a 6'4 rider will almost certainly need a non standard 450mm seatpost, which are not really made with setbacks one would require with the 74 degree seatpost angle.

I'd say none of the pieces fit correctly and the end result would be a monstrosity even for the vast majority of pro riders. Even though tall riders are able to tolerate more drop, a 22cm bar to saddle drop is just insane and extremely rare. I think the most I've ever seen in the pro peloton is around 20cm. At that point most people will lose significant amounts of power due to suboptimal riding positioning
