The bike I am getting is a 2015 Felt IA FRD and wont have a chance however to fit it until after I have it.
Whence I would appreciate your input on the remaining queries.
I am 1m82, with inner leg 90.5 cm.
Frame size is 54 cm. Please confirm that this will do :)I am determined to use 25mm tires (on Firecrest 808 rear wheel), a practical confirmation whether the frame is permitting this would be fantastic as my LBS is unsure (he needs to try out, I agree)
What would be recommended training wheels, which have the same width as the Firecrests?
I am 183 cm with an inseam of 88,5 cm and ride a 56 frd with 165 cranks and have a drop of 13 cm. That is with a angled 2 cm spacer (so it is mot really 2 cm on the back of the spacer) . So you better make sure can handle a drop of 15 -16 cm or if less you need a substantial amount of spacers under the armpads.
I m 184cm and am getting a Size 54, and that is through a very good fitter! Don’t know what my innerleg is. Frame can take 808 with 25mm tyres.
I will run Enve 7.8 with 25mm tires, and got a Zipp Suoper9 Disc as well for it! Training Wheels wise, I just use my Enve 7.8 all the time! They handle fine for pretty much everything! And I do a lot of sessions on the Kickr as well!
I have this bike and have a Zipp 808 with a 25mm tire, no fitting issues. I had to adjust the set screws in the horizontal drop outs and the brake, no frame rub issues.

Many thanks for the inputs - seems things will work out pretty well and I will make sure to visit a pro fitter!
@Tri-run, what are the chain rings you are using, as well the cassette specs, in combination with the 165 crank?

I ride a Absolute Black oval ring in 52/38 but never use the inner chainring. I am living in the flattest country you can ride in :-). Cassette is 11-23

You can get a bike fit before you get the bike.
What matters is the relative positions of the bottom bracket, saddle, armpads, extensions and the crank length. For choosing the frame and size the most relevant measurements you need to identify are the horizontal (X) and vertical (Y) distances from the bottom bracket to the arm pads that you will require. Just plucking numbers out of the air, lets say your fit says you should start with armpads at X=490mm and Y=600mm. You can then ask here, or look up Felt’s configuration calculator and find out which frames can accomodate that. It’s a much safer way to go than trying to make a guess based solely on height and inseem measurements. If the frame accommodates your X and Y coordinates, you can then look further at adjustability of the saddle and how much adjustment will remain in the front end for later tweaking but you’ll have a solid place to begin and will not buy something completely inappropriate.

Thanks all for the suggestion of seeing a good bike fitter.
The fit recommends to go for a 56 frame, given my long leg length (saddle height 82 cm, with 182 cm body length)
Based on the below outcomes:
Saddle height 82 cmSaddle ISM Prologue Adamo: minus (-) 6 cm vs the crankshaft.
Reach based on ISM Prologue: 60 cm, with 21 cm pad spacing (center to center)
Initial drop 9.5 cmCrank 165 mm (55 deg angle, instead of 51deg @170mm)!
Is the FRD 2015 56cm frame able to accommodate this, esp. given the built-in steer/aero bar.
What is the max drop possible given the frameset and a 82cm saddle height?
I would like to ascertain that the bike is future-proof for when I will be capable of riding with larger drops
The fitter recommended the Prologue saddle, vs the Fizik Tritone; any preference on your end?
Off the top of my head because I don’t have the bike next to me i don’t think you will be able to get the drop of 9,5 cm (if you mean saddle to armpad drop) unless you build a serious tower of spacers.
I have saddle height of 79 cm, 165 cranks and a drop of 12,5 cm with an angled custom made 1,5 spacer. So quite unlikely to come to 9,5 cm of drop.
So the good news is that for the future, drop can be well-managed.
Has anyone experience in adding substantial spacers on this bike (i.e. 7-8 cm?!)
I guess that independent of the bike brand (eg also for BMC TM01 M-L) , this might be an issue.
Thus should I be looking for an even larger frame, or for a fancy/acceptable way of skyscraping spacers?
Sure, but i thought you mentioned a 54 cm size. But even in the 56 cm, if you are not sure if you can handle a larger drop why not get the fit first instead of doing a lot of guessing in th if/or/might regarding the fit. You go from an OP of 54 cm size to a 56 cm amd you gestimate that you might can handleva larger drop but you are not sure.
So you are spending, even when it is a great deal, an serious amount of money, you are likely not sure about your actual position. You say that your fitter advised the ism prologue or the fizik tritone? But in the original post you say you cannot see a fitter after you get the bike? So on what is that saddle advise based?
If can get a fit after you have the bike i cannot see why you cannot have it before. In just 6 or 7 posts you already sized up 1 frame size. Save yourself a fitaster and get fit first and the bike after that when it fits you or not at all. A great deal that doesn’t fit is not a great deal.
Thanks a lot, so yes i did a bikefit based on the forum’s recommendations.
Recommended frame size is 56cm.
The fitter did not know the FRD frame on how to manage the drop exactly.
I am hoping to validate the drop - is it possible to accomodate some defty spacers, vs. should i be looking for an even larger frame (can i still manage the reach)
you can raise the base bar up to 45mm . it comes with a 30mm spacer and a 15mm spacers that fit under the stem . in the original frd thread superDave (used to be the felt pm) said it’s safe to use both together , but you need to source a bolt long enough(which will be easy to do)
above the bar, you easily have 45mm of height , via a 40mm spacer (included) plus the 5mm bridge to stabilize(for use with spacers above 20mm).
so, that’s 90mm of stack with extra hardware, or 75mm with no extra hardware.
the manual for the is is here if you want to see how it’s configured .
Although completely true the bike looks awful with that 45 mm under the basebar. In my opinion, if you need that 45 mm under the base bar to make it fit just get another bike

I’d suggest that the spacer above the basebar to the arm rest / extension mount should be kept <20mm or >60mm for optimal aerodynamic performance.
