GW Posted January 11, 2016 Posted January 11, 2016 Hi all i know there is not allot info about this but i was thinking of taking a 29er dual frame and putting 27.5 rims with plus size tires, does anybody knows if this will work?
Iwan Kemp Posted January 11, 2016 Posted January 11, 2016 Frame dependent as you need proper clearance and most 29ers won't have enough for a plus tire to fit in the rear tri
Captain Fastbastard Mayhem Posted January 11, 2016 Posted January 11, 2016 depends entirely on the width of the frame at the critical points. Some frames are more suited to it than others, as the width of the chainstays & seatstays varies between frame designs.
Steven Knoetze (sk27) Posted January 11, 2016 Posted January 11, 2016 Sure there was a vitalmtb write up on this last year.......
Long Wheel Base Posted January 11, 2016 Posted January 11, 2016 Sure there was a vitalmtb write up on this last year.......+1, Definitely rings a bell.
Steven Knoetze (sk27) Posted January 11, 2016 Posted January 11, 2016 Perhaps mention which bike you are looking to do this to?
Steven Knoetze (sk27) Posted January 11, 2016 Posted January 11, 2016 Can't find the article I am referring to but I found these in the meantime.Happy reading: http://www.singletracks.com/blog/mtb-gear/how-to-convert-your-29er-to-a-27-5-all-trail-bike/http://www.bikeradar.com/mtb/gear/article/trail-tech-converting-29ers-to-27-5-just-dont-do-it-42060/http://www.singletracks.com/blog/mtb-gear/27-5-tires-these-are-for-your-29er/ Also found a MTBR thread of a crazy guy looking to cut his Anthem swing-arm down the centre, extend its width to fit the 27.5+ tyres. He abandoned the idea though.
GW Posted January 11, 2016 Author Posted January 11, 2016 Hi all, i dont have a frame yet i was thinking of just looking on classified for a good second hand frame, i currently have a normal 650 but the plus size sounds very intresting but i am not sure if i can make this work

Only MY16 29ers will have this design in mind and even then only a handful of frames do offer compatibility. VIPA Trail and Scott Genius Plus are two I know off. Keep your bike and fit super wide rims. I have 35mm internal rims on my 650b with 2.35 / 2.25 tires and the increase is already more than enough.

s14phoenix Posted January 12, 2016 Posted January 12, 2016 THIS. The difference is huge. HUUUUUGE. What rims are 35mm??? daaaaaaaamn!!! Wide Lightning????
Captain Fastbastard Mayhem Posted January 12, 2016 Posted January 12, 2016 What rims are 35mm??? daaaaaaaamn!!! Wide Lightning????Derby, in this case. But there are others - ping v12man - he's go a source for a 36mm internal rim which is apparently VERY well built.
Odinson Posted January 12, 2016 Posted January 12, 2016 I'm toying of the idea of having a better wheelset built later this year and was considering WTB's Asym i29 or i35 hoops. Now, say I go for the i35, is it possible that you could run into frame clearance issues? Is there a way to calculate or guesstimate how much wider the tyre would be on such rims?

Captain Fastbastard Mayhem Posted January 12, 2016 Posted January 12, 2016 Cost estimate on the rims?I think $ 160 per. IE mucho grande expensive.

Is there a way to calculate or guesstimate how much wider the tyre would be on such rims?tyres wouldn't be wider at the widest point, they're wider at the bead, which gives them extra volume. So no, shouldn't have tyre clearance issues if you're using the same tyres. A 2.35 would still be a 2.35 as that width is measured at the widest tread point, and the circumference stays the same 'cos well, the circumference can't increase.
