Would you rather go down in bike size or up?

Looking at the Mongoose Canaan Elite, I've ridden both the Small and Large sizes. I'm 5'9", normal proportions, so the medium would be the obvious choice. In reality, the stock small is a bit small and the medium a bit big. Both would represent a compromise:

Small-have to get a longer seatpost (comes with 260mm, 300 or 350 would be plenty) and possibly a longer stem (don't think so though). This would have the effect of raising the saddle higher than the bike would normally be, and I might be slightly more hunched over. It feels pretty nice & roomy though. Standover height would be good at 715mm/28.1".

Medium-definitely have to get a shorter stem. In it's stock setting, my elbows are locked straight.
It comes with a 110 I think and I would likely need a 90 or so. The seatpost would be lower so not as hunched over. Standover I think is not so great on the medium at 757mm/29.8".

Which compromise would you choose? Is running a seatpost fairly long a concern?

I'd say look at some other bikes. An improperly sized bike is no fun.

At 5'9", do you really have a 33" inseam? That's what you'd need on the medium to get 3" of clearance on the top tube. I personally don't like to ride bikes that have much less than that. It's just too painful to think of the consequences.

As for seatpost height, having lots of post showing isn't that bad. Here's mine





As you can see there's lot's of post showing. I'm a big guy and I've only bent one seatpost in years of hard riding. Not much of a concern with a 31.8mm post however.

I'd say go with the smaller frame and a little longer stem. Or, like Hanzo said, test some other bikes first.

Thanks peeps! The small size does feel more maneuverable and comfortable, especially on the top tube clearance. And it is in no way cramped. I'm still looking at 1 other used Stumpy FSR on CL, and if I can't get it for the price I'm willing to pay (I have a $ ceiling), I think I'm going to give the 'Goose a try. It does ride really well, though I need to take it to the hills on an extended test ride to be sure. I figure if I don't end up liking the frame after a while, I can swap the awesome parts onto a different frame down the road. This bike is priced such that the frame is basically free.

I hear nothing bad about the i-drive technology, which this bike borrows heavily from. In fact, all good. I'm really torn as to which to get.

I would personally go smaller. I have ridden several bikes that "fit" me properly, but don't like the way they really feel. Go with what you feel more comfortable on. Make sure you feel that you can move around easily on the medium, side to side, and make sure you could get you but back over the seat if needed for a steep, slow downhill.

I would not suggest you get the smaller size. The discomfort and pain of riding a smaller bike is almost as much as riding a bike that bit too large.

its pain to pedal a small bike on a climb. when you play with the stem and seat post too much, your position on the bike is really wired. and that may cause serious handling problem and injury. your knees and ankles may stress too much bacuse of your position and pedaling cycles.

The only and significant problem of going with a larger frame is the standover height. Cause if you dont have enough clerance and crash badly, you can injure your sensetive parts. but, overall I prefer a bit larger bike. cause a longer top tube and a shorter stem is really nice for quick handling.

By the way, whats the length of your inseam? I am 5'10" with 33" inseam. and I ride a bike with 29.4 standover height. However, I dont do FR or downhill type riding. My style is mostly AM (on the XC side of AM).

good luck .

I don't think the small is the wrong size. In fact, either could be made to work. I meant that components would have to be switched out to make a perfect fit. It's common to do this. I was just asking whether people prefer going up in frame size and substituting shorter stems, or down in size frame with a longer stem.

As it was written by others, the best option is no compromise. Find a bike that fits you properly. The Mongoose is not it.

If I had to choose (and all else being equal between bikes, type of riding, etc) I'd go down a size. Better control and when I want to bail, I want off fast (not getting hung up on the tubes). Interestingly, I've moved down in bike size the more years I've ridden. I don't think that's uncommon; I hear of a lot more riders moving down a size than up a size over the years.

Smaller frames have nicer angles.

I'm always bummed when I see what a bike looks in my size.

Although I feel the same way about shoes. Nice looking shoe in a normal size.. flippin' ridiculous in a 14.

Sounds like rider preference.

My inseam is 32", so the Medium would provide me 2" of standover and the Small would provide 3". 2" really isn't all that bad, 3 makes my boys relax.

I think I've really convinced a few people that neither of these bikes fit. They both do. The Medium would require a 90mm or so stem vs. the 110 on there now and possibly moving the saddle forward 10mm or so (both quite normal changes). The small, with only a 260mm seatpost (185mm/7.3" usable), might require I swap it for a 300mm saddle. I need at most an additional inch. That would mean that the seatpost would show about 8.3". I think that is probably less than most people show from what I've seen.

I didn't do any of these mods to either bike yet, because I haven't pulled the trigger yet, and may not depending on my Stumpy negotiations this evening.

At the end of last year I had two bikes and one choice - I had a Specialized Stumpjumper FSR and a Santa Cruz Superlight. Both were "mediums" 17". One bike as alittle too big (the Spec.) and one was alittle small (the Santa Cruz).

I sold the alittle too big one. Just got very tired trying to reach the brakes and still get off the back of the saddle. I was really stretched out. The gal that bought my bike was way too small for it but oh well, it was a good sell for me. I am so much happier with my Santa Cruz. Just goes to show you not all bikes are the same size even when they are the same size!

My Stumpy negotiations went well, so I am soon to be the proud owner of a Medium FSR. The Mongoose will have to go to someone else. Pics possibly tomorrow if I get it before dark!

I ride an undersized frame and I love it. Then again, it was built up with the small size in mind. Works awesome for technical bits and even pedals better than I origionally thought. 100% comfortable position as well.

I've been riding it for almost 2 years and I'm recently noticing the limitations of the undersize setup. Whenever the bike points steeply up or down, the bike gets pretty cramped. And the smallish cockpit and wheelbase makes for unstable high-speed cornering.

It so happens that my skillset has always been weak in the steep descent and cronering departments. I've recently hit a skill growth spurt and I'm going to give it a nosefull of crushed up adderol with a FRAMESWAP. Which I am super-excited about and will be alluding to over and over and over. Even in discussions where it is mostly innapropriate to do so.

When I went to my current ride I went down to a 14" frame, and it does feel better to me.
