Cyclocross and Gravelbiking (Recreational) This has to be the most physically intense sport ever invented. It's high speed bicycle racing on a short off road course or riding the off pavement rides on gravel like : "Unbound Gravel". We also have a dedicated Racing forum for the Cyclocross Hard Core Racers.

Picked up my first CX bike Friday

Picked up a leftover '17 CAADX105. It's my first with geometry different than a MTB. I'm 5'3" and feel i was between a 46 and 51 and decided to go 46. I think i need to adjust to the geometry as at first it seemed small but standover is about as high as i could i think, i can flat foot but the boys are getting a light lift from the tube lol. I need proper pedals as i get toe overlap if i dont think about it and try turning sharp. Yet my elbows have no bend when on the hoods so i think i'm going to spend the money on a proper fit as some aspects seem big others seem small so i feel it'll work out. Bike is super light, rides way smooth and is so much faster accelerating from what i've been riding. I do really like the bike just hoping the fit will work out. Did 20's miles yesterday and it was my first time on a bike since aug 1 and i felt great compared to having taken a break and getting back on the mtb

Not to be a downer, but they make a 48. That probably fits you just right.

Oops. My bad. I was thinking you were caught between 56 and 61. That sounds like a crazy big gap, but I"m not even sure what their sizing means, as the 46 looks to be only modestly smaller than the 51. You should be able to make that fit no problem.

Yea they do have an inbetween on other frames, I figure with a proper bike fitter I can get it figured out since some aspects seem large and others small prob just need tweaking. I got pedals ordered up today

I test rode one of those but didn't end up buying it, but really liked the ride. Seemed like an amazing deal for the 105 kit. When I saw it REI had them for $1250, ended up getting a new Anyroad for a few hundred less.

Yea with all my other contenders being in the $1800-$2200 range i felt for $1250 and a 105 set it was worthwhile.

Enjoy! I love the way a CX bike accelerates and climbs compared to a mountain bike.

Not sure you can do anything about the toe overlap on that small frame. If you really wanted to, you could use shorter crank arms, but that isn't doing to buy you too much (5mm maybe?).

It sounds like the bike fits you - what on it feels small?

Agreed. $1250 for that bike with 105 is a steal. Enjoy your new ride!

Standover means nothing, just lean the bike over a bit when you're stopped.

Awesome bike. I was looking at the CAADX105 before I decided on a Motobecane Gravel bike with 105. I prefer the endurance geometry on gravel bikes as opposed to the race geometry featured on the CAADX frame. The '17 CAADX looks better than the '16 model, IMO.

congrats! was just looking at a pre-owned one about 1 hr from me. I really shouldn't buy it cuz I'm hardly riding as it is. tho getting another bike would surely MAKE me ride more. well that's the logic I would test on Wifey anyway

I had been super consistent march- june then life got busy and it become sporadic plus riding a 27.5+ mtb the way i was just wasnt doing it, really felt held back. My new pedals should arrive today, gotta find the right fitting shoes though and then i'd like to get a proper fit done. Took it on some crushed limestone horse trail tuesday night. Was so much smoother than i had expected up until i got into some really rutted stuff from the horse shoes, that was pretty brutal on my hands.

have you been reading the new thoughts on tire pressure?

I found this podcast (shared by another BR member here) really interesting

well Heine has been saying that for years, but he has changed the world.

Like my other post says, my 60mm schwalbe tires are faster than ANY of their road racing tires (assuming you are riding conditions where weight and aero are not an issue). For me, it was a strange experience first time I put them on...

And none of that makes any difference if you don't run tubeless. Tubes + low pressue = pinch flats.

Yea id have to be tubeless, im currently floating around 200lbs so low pressure and tubes would be a nightmare i assume. I'd be in pretty good shape between 175-180 and even there i think i'd be a bit heavy for tubes and low pressure
