Hi Everybody,

I know fitting is complicated and best left to experts, but I was hoping to get your prospective on an issue.

I have a gravel grinder cyclocross Felt F85X and it is in a 53, I find the geometry rather difficult for comfort vs. my other bikes which are endurance road frames.

Would buying a 51 or smaller frame help create slight similarities in the endurance geometry on a different type of bike?

Thanks again for all the help,

J.

Are you talking about making it comfortable in a true cyclocross riding situation? Or are you just taking a cyclocross bike and riding for leisure on the road? Or perhaps riding more aggressively for fitness on the road?

Cross races are only an hour long max, and has a lot of accelerating out of tricky corners..

"Cyclo cross" gets generalized , a wider tire capable drop bar bike, that is lighter built than a touring bike is often what they are.

That's it exactly, i like the cyclocross bike, but want a little more comfort. Would you think a touring bike might be better?

Measure the stack and reach of your endurance bike that you like the fit of.

Measure the same of your current cyclocross bike.

Compare the difference and see if that can be matched with spacers and a different stem angle/length.
If it looks possible, then use an online stem calculator to work out the correct stem length and angle, to match the stack and reach.

The above assumes both bikes' handlebars have the same reach and drop measurements.

As [MENTION=338271]tangerineowl[/MENTION] said, it is likely going to be the stack and reach that you need to look at to simply get your position to what it is on your other bikes.

If your seat height to the crank is pretty much the same as your other bikes and they don't have a big difference in seat tube angle, then you probably can eyeball it and use a tape measure to compare between bikes.

The other bikes you say are comfortable have drop bars too?

By 'more comfort', do you mean a more upright riding position?

A smaller frame will not have a taller head tube.
