Feels like I’m between S and XS frame size.... which should I go? Which is simpler/easier to adjust to the right fit?
Riding conditions are: 1. I’m no racer; just a hobbyist. 2. Had little experience on RB during the younger years. Long time MTB rider, stopped for several years, then went back to riding for almost 2 years now. 3.Got tired of the trails and now goes on 100% paved roads (the main reason for the shift to RB). 4. Ride 2x to 3x a week, between 20kms to 50kms trip. 5. Mostly on flat, but occasionally go on climb (i. e. Marcos Twin Mansion, Cardiac, or Tagaytay).
Now eyeing on an entry level built bike; too busy to take the “bike building” path 😔. Have had tried a S and XS bikes but of different brand/model and components... and are also different from the RB I’m planning to buy.
To add, the only important numbers to look at when it comes to sizing a frame are reach and stack. Once you've nailed the correct length needed by your body against these, choosing a bike frame will be a breeze regardless of what it is.
The other figures in a frame are only specifics to how one rides his bike or what bike it is. Seapost height doesn't (will never) determine frame size objectively as it varies by design.
Okay, I’m leaning on an entry level giant contend (forgot to ask what year model) built bike. Sat on the S and XS, but didn’t test ride the bike yet (will have the actual test ride when I’m already decided).
Looks like both the S and XS will work for me, but I want to know which is easier/simpler to fine tune the “fit”, if ever, for a more comfortable position depending on the type of ride (i.e. beyond my average distance rides).
regardless of it's S or XS, both can be fine tuned.
like what Spyghost said, measure your stack and reach. the S and XS sizing takes the seat tube length which by all means is irrelevant because of the sloping top tube designs.
here's my forever example. I used to have 3 mtb's of varying sizes. MOB size is 16" or small, a bootleg Diamondback is 18" or medium, and a Schwinn at 19" or Large. Things is all these 3 bikes have the same ETTL. Mated with a 120mm fork will have the same bb height. All I needed was a shorty stem which i favor and the handlebar height that i also favor.
so like i said, the S, M, L sizing won't really help, get the numbers in, then swap out the parts if you can bargain with the bike shop. a long time roadie i knew had a proper bike fit after more than 10 years of riding, apparently his saddle is 5mm off his body measurement. After the adjustment, his back pain went away.
Sir pareho tayo. May rb na rin ako. Cannondale Caad. Tama pagpili mo ng smaller size. Ako rin namroblema kung size 51 o 54, ksi in between ako. Pero sabi sa kin, pag in between, go smaller, ksi daw mas madali mag adjust ng fit sa smaller frame. Di gaya sa mtb na ok lang pag medyo malaki ang size, sa rb kelangan daw tlga maganda fit sa yo. Size 51 rb ko, fits like a glove dhil mahaba nman stem. Pwede ko pa nga bawasan ng spacers para mas mababa yung drop pero tsaka na pag medyo sanay na ako.
