Converting RS Revelation 426 from 26" to 29"?

[garethrl]

Hi folks,
This my be a fundamentally stupid question, but can I convert my 26" fork to a 29" fork?

I have a ~6 year old Rockshox Revelation 426 U Turn fork and I want to know if I can convert it to a 29" version? I'm not a suspension expert by any stretch. Is it possible or practical to replace the lower legs to an equivalent 29er part to allow use of a larger wheel - on a different frame, I should say!

I've been riding the Rev on my 26er for a few years and it's been fairly well looked after and services. However I'm thinking of a fork/wheelset upgrade for the 26er and would likely choose a thru-axle setup. At the same time I'm trying to build up a 29er and remain short of a fork.

The Felt 29er frame I have takes a straight 1 1/8" steerer - which the Rev has - and the recommended travel for the frame is 80-100mm. Then the wheels I have are 9mm QR front and rear, so that further limits my options. I think the Rev 29er variant was 15mm, but would perhaps a 9mm Reba 29" lower work?

Do I have any options for a 29er fork lower legs with 9mm QR dropouts which I can mate with the Rev upper/steerer assembly to given me a safe, functioning fork? I suppose that the travel adjustment will be helpful in regard to setting the fork to suit the frame.

Many thanks in advance for all tips and suggestions, and please let me know if it's a really stupid question or idea.

Cheers,
Gareth.

Re:

I can't imagine that would be possible tbh. Even if it is I can't see how it would be worth it when you could just sell the ones you have and buy the pair you want.

Re:

It's probably possible to make a fork that bolts together and stays in one piece. It is not possible to make a fork that's right and works as it should.

It isn't just a case of changing the lowers as the stanchions, spring assembly and rebound damper have to be the right lengths as well. Plus there are about 6 billion variants of every Rock Shox fork, so your compression damper is probably wrong as well.

If you study the Rock Shox service manuals and spare parts catalogs (they are available online), there's a slim chance you might find a way but it's odds on you won't be able to do it without spending almost as much as a new fork would cost and it will always be a bodge.
