2014 Whyte T-129s wheelset upgrade

ben11

Hi Guys, I'm considering upgrading the wheelset on my Whyte as it looks like I can save around 500g rolling mass in doing so which is quite an attractive prospect.
I've mainly been looking at a Crest rimmed set as they seem to have the best weight claims for the £ and have also used the 26" version on my hardtail and been pleased with the results.
The only thing I'm not sure on is the hubs / axel. I've found a seller on ebay in poland who does various builds with great weight claims and price. It says you can convert the hubs to 100x15 / 142/12 - is this correct for my bike?

If you go onto their store there are loads of different builds, any info / recommendations would be appreciated. Cheers.

crests are quite soft for the t129, if you plan to get aggressive at some point most probably won't hold up, used novatec hubs before, their alu freehubs were to soft that cassettes dug deep and difficult to remove. go flow ex and basic dt swiss hub if he does that

The Rookie

Alloy freehubs are fine with spidered cassettes, also many Novatech hubs now come with a steel insert that prevent digging in.

What makes you think the crests will be too soft? I've ran them on my hardtail for years without any problems

people had issues when riding hard, not suitable for gnarly terrain, at least not as tough as a t129 needs anyway.
where do you ride? if the trails are smooth maybe won't be an issue
