Is there anything and reason to perhaps advise against that and what would the factors be?!
It might also be worth considering whether you'd be better off with either a shallower or deeper rear wheel than the 88. I got a similar pairing to that for my tri bike a while back (62.5mm front, 85mm rear) and have been very happy with it, but in retrospect either 62.5mm front and rear with a wheel cover as a disc option might have been a better choice. Reason being, any conditions where the 85mm is okay (which is always in my experience to date) would also be fine for a disc, which would be faster. Any conditions not okay for a disc would also not suit the 85mm rear, but a 62.5mm rear might be okay. Two 62.5mm wheels would also make a slightly preferable match for my road bike (although 62.5/85 is fine) and the cover is a minor extra cost to cover all the bases.
