I'm pretty new to MTB. Coming from BMX during younger years pa... So, i got this assembled mtb from a friend. It is a 16'/(S) 29er frame with xt/slx groupset already. I like the color and all, and the size just right. But.... it was matched w/ 26er wheelset and fork. So huge dropped in BB ht (thus, lots of pedal strikes when i tried trail, but quite fine naman sa paved roads. I'm 5'4 and i don't feel like going 29er wheels to match the frame Had red somewhere about 27.5+. So i'm thinking to convert following below... - change to 29er fork - wheelset change to 27.5 x 2.6 (or at least 2.5), problem is, market has limited offerings for these tire sizes... available now is 2.4 next would be 2.8 na. I don't think i could fit a 2.8
Below are my Qs... - Should I pursue this conversion? I like going trails, maybe up to lite technical trails. And red somewhere that wider tires are OK on trails. Or, replace ko na lang frame ko to 26er or even 27.5er - If I pursue w/ the conversion, is the 27.5 x 2.4 enough to provide me higher bb ht clearance already?
Ty in advance for the advices.

By the way, crank length is 170.

Had that same dilemma before, also got a small 29er, I found out that you can somehow fit a 27.5+ tire in it, but what kept me from pushing it through is the availability of plus tires.

IMO, go 29 all out. Frames are adjusted to the wheel size. 5 foot guys can ride a 29er.

tama, just like what anthrax76 said go with a full 29er wheelset na. kasi fit naman sayo yung frame size.

magugulat ka sa mas madaling iakyat ang 29" kesa sa mas maliit. or it might just be me, hehehe... 29x2.4 mataba-taba na yang gulong na yan. ako nga kating-kati na bumili ng DHF/DHR na 2.8 kaso di pa pudpod ng maigi ang gulong ko (Chronicle 3.0) so malamang next summer na or this winter

Thanks for the replies. Feeling ko kasi parang nilulunok ako ng bike pag 29er. Hehe. Ang laki! I'll take the advices. Will give it a try. Will keep the frame. Then will match with another 29er fork and wheelset. Nabasa ko lang din somewhere here na dehins advisable ang 29ers for tight trails (hadn't tried any full 29er yet).
Also, based on your actual experiences or assessments, how significant the 27.5 x 2.4 (or 2.6 if I could find a set) can give, speaking of pedal to ground clearance on a 29er frame? Pwede na ba sa trails yun w/o worrying much of pedal strikes?
I'm now thinking of 2 wheelsets na for my frame. Whew!

I would go against the other posts and advise you to go 27.5+ instead. It doesn't sound like you're a racer and that you're probably more of a recreational biker.
Plus bikes are a lot of fun and gives you a big footprint in terms of traction. After a couple of rides on difficult singletrack, you will notice the difference in grip and you will feel like a better rider.
Best to look for tires in the 2.6 (Schwalbe) to 2.8 (Maxxis) range. Do note that different brands differ in terms of ACTUAL widths relative to the size listed on the tire. For instance, Schwalbe's 2.35 is equal in width to Maxxis' 2.5.
As for wheelsets, you will need rims with at least a 30mm internal width and up, with 35mm of internal width to be the sweetspot. Not sure if your rear can accommodate a boost hub but you should at least be in 135x10 or above. If not, then you can always go with a lesser volume tire in the rear (2.35-2.5 on a rim with 27-30mm internal width).
And don't forget to run tubeless. It's just plain asinine to go the plus route with a tube, as there is far more risk to pinches and snakebites. You should be fine with about 10-15psi.

Fabio Wibmer's Stumpjumper FSR is a 29er but he has 27.5" wheels installed. Like frame sizes, people tend to choose larger or smaller sizes with preference to stability or handling, respectively.

If you're looking to trade, i got a 27.5 medium Giant ATX frame, from a built bike, bagong bago pa halos. Di nman ksi nagte-trails yung owner. Sa village lang ginagamit.

Below for my currently installed wheelset. Front 26er: Fireeye Rim 32h (not sure of internal width but external manual measurement is ~27mm) Nobby Nic Performance 26 x 2.25 Amoeba hub 6512 Amoeba QR (not sure of details) Rear 26er: Fireeye Rim (same as front) Continental Mountain King 26 x 2.2 Amoeba hub 6512 Same QR as front 2x10 speed - do i need to replace my hubs? Can u recommend suitable set? - fireeye (seller dominion ata yun) offers 35mm (ext) width rims, maybe around 30mm internal, would that be ok? - schwalbe ph per their reply to my inquiry only offers 2.35 (next would be 2.8), none in between sizes. I'm also thinking of something like 2.5 or 2.6 sana as excellent fit (but can't find any). Do you think the 2.35 would be just fine already? - as for the fork, saw Rockshox Reva 29er sa Stan13.. oks na siguro yun. Thanks a lot.

What frame do you have, btw? FRONT: You will need to replace your fork. For plus bike purposes, you will also need to replace your front wheel (hub, spokes, rim, and tire). "QR" isn't gonna cut it, you'll need to move to a thru-axle setup. Get boost if you can. Check if the RS fork you're looking at can fit a 27.5+ tire. REAR: You will need to at least be on 650b for the rear. I don't think a 27.5+ tire will fit in there but you can try or do research. If it can't, just stick to the rear wheel you have and get a tire that's 2.35 Schwalbe or a 2.4 and above Maxxis. - your choice of hubs will depend on whether you can source the stuff you're looking for; in terms of entry-level brands, tho, Novatec is good as they do World Cups - 30mm internal and 35mm external will be ok for a plus tire but ideal is 35mm internal width - 27.5+ means a tire width over 2.6"; 2.35 in Schwalbe terms is AM/Enduro/DH, this is equivalent to 2.4 to 2.6 in Maxxis; - the Philippines has very few plus sized tires available so you will have to look around and consider other brands like Michelin, Conti, WTB, etc Also, move to tubeless; which means tubeless tires.

Thanks guys! Medyo masakit pala sa bangs tong mixmatching... prone sa mismatch. Hehe.
Frame po is 16'/Small XTC advanced 29er.
Pls disregard my term 27.5+/plus, no plan of going 2.8++ tires. Weekend biker only po for health and family/friends' bonding days.
I'm thinking of just using 27.5x2.35 (or 2.6 at the most). Will be matched w/ 29er fork on my 29er frame.
- my primary concern is the pedal strikes (hopeful that the 27.5x2.3 would give me enough pedal to ground clearance). Will look for accommodating shops that will allow me to test fit parts before to actual purchase.

well, you are lowering your BB because you are putting in smaller wheels. you are indeed increasing your chances of pedal strikes. that is just facts.

Stick with the all 29 setup na lang, wala ka pang problem. At least toe overlap na lang problem mo, dehins na pedal strikes.
If you feel kinakain ka nung bike because of the wheel size, get rid of the feeling.
