A thread about a month ago discussed some of the options, try here. I have run a 29er Scandal both rigid – with a Salsa Cromoto fork – and with an RST M29. It is currently back to rigid while I wait for some replacement parts for the M29. I also have a FS 29er with a Reba 100mm QR up front.
I run the Scandal as a winter bike. I really like the Salsa fork. I haven’t tried carbon forks for reasons of expense and the fact that I am a Clydesdale but a recent WMB test[/url] went for the Salsa ahead of the carbon offerings anyway.
On tarmac and smooth bridleaway I don’t notice much difference between the Salsa and the M29 and any extra bumpiness is made up for by the weight advantage. Once things go downhill and a bit rougher the suspension does save my wrists from undue punishment.
On the full sus, I would have preferred to go for a Maxle Reba but just couldn’t easily find one with a straight steerer. May be easier now and there were some suggestions on possible sources for them in the other thread. Other than possible peace of mind, in reality for the XC stuff that I do round the NY Moors, I am not sure that I notice any issues with having the QR version instead.
Manitou Tower Pro gets good reviews but getting spare springs if you are not of standard weight seems problematical at the moment. Their 20mm axle design also appears a bit more faffy than the Maxle. There is a good review on one of the US 29er specific websites – here[/url] – but not unsurprisingly they didn’t have any issues getting the spring kits.
