Title: I need new wheels - help!
Post by: James R on 04, January, 2021, 10:42:27 PM
My rear wheel is hopping all over the place when it moves at any speed. I was told it was on the way out by the bike shop about a year ago so I figure after almost 5 years it’s probably overdue retirement. I want to make sure the wheelset is compatible with current bike components so I don’t have to go buying loads of additional parts when I plan on selling the bike in the near future.


Bike is a Canyon Strive 2016. The current wheels are DT Swiss E1700 Spline 2 27.5. Cassette is standard SRAM GX 11 speed


Was looking at:
https://www.bike-discount.de/en/buy/dt-swiss-e-1900-spline-27%2C5-30mm-cl-rear-wheel-792358


Would 12/142mm - SRAM XD fit it or would I need to go with 12/142mm - Shimano to fit my non XD cassette? Or is a non XD  fit called “Shimano”?!


Or would something like this be better:
https://www.chainreactioncycles.com/ie/en/nukeproof-horizon-v2-rear-wheel-102t/rp-prod195301
12 x 142 HG


OR go for the set of cheaper Nukeproofs:
https://www.chainreactioncycles.com/ie/en/nukeproof-neutron-v2-27-5-non-boost-pair-with-ard/rp-prod202474


Am I correct in thinking 148 x 12 would be for boost and too big for thru axel?


Cheers,
James

James,
You need 142mm spacing if your bike frame is non-boost. As you said the 148 is boost and would be too wide for your frame spacing.


I had a SRAM GX 11 speed on my old bike and it was an XD driver rather than HG (Shimano/SRAM NX) driver.

Yeah, would have thought it was an XD hub you have already.


I seem to recall someone telling me that a certain bike shop, which shall remain nameless, shoved a boost rear wheel into his non-boost frame, so ya never know 😂

Think that HG or xD would work for an 11 speed GX cassette. I reckon it would be better to go with xD, particularly if you're intending to go to 12 speed at some stage.

Hmm maybe it is XD. The front takes a maxel thru lever. See pics! Would have thought it was the same setup as yours Aaron.

Mine also came with a sram 11x cassette and it's definitely XD.

Thanks for confirming! And no boost right?

Yeap you're right it's definitely not boost - 142mm it is thanks.

James, I have the DT Swiss E 1900 wheels on my bike, and while they're a decent, solid wheel, I can wait to swap them out for something a bit better spec - lighter and with more points of engagement (POE) on the free hub.

The free hub body is a 3-pawl set up, which is just 18 POE, so you basically have a lot of play in the cranks.  It's noticeable when you accelerate out of a corner etc. and when track standing, or ratcheting.  The Nukeproof hub by comparison has 102 POE, which is a hell of a lot.  The average is more around 40 - 60.  Hope Pro 4 for example is 44 POE 

Have you spoken to Expert Cycles?  They could price up a build for you.

Dt swiss 1900 is unfortunately the pawl system which is not very durable and not many point of engagement. Dt 1700 and 1501 with 350 or 240 hubs are bomb proof ratchet system, you can amend points of engagement if you wish. I used to have 18 poe and amended to 54 and it made huge difference. Anything beyond is pretty much pointless as 54 gives instant response when you crank up. You can use non boost wheels on boost frame by using spacers but not the other way around...

I used this crowd on a couple of occasions  when buying wheels and great service and value. All wheels hand built to your spec weight, terrain etc

Got any more details on that, Pawel? I have a E1700 as a spare wheel and find there's an annoying amount of play in the hub compared to my Hope Pro 4.

You need this set Aaron. Its a 10 minute job to install. There is also 36 tooth set a bit cheaper. I also saw a chinese version on alibaba for 5 eur but didn't want to risk damaging the hub. You can remove it when selling bike and use on other wheels etc.

I would recommend doing a quick hub service while you are at it. Check out servicing 350 hubs on YouTube, that's what you have on 1700 wheels. You will need a special dt swiss red grease for lubrication. I have a couple of spare ones i can give it to you. You only need a tiny bit

Cheers. A bit pricier than I expected, but I'll consider it.

Defo quite expensive for what it is. The good thing you can always use it on other wheels or sell when no longer needed

It's a great excuse to upgrade to a new bike ;)


however, if it helps, I have the DT Swiss M1650 spline in mine and the freehub came with the rachet system, it works pretty well although the freehub gets scarred with the use, it seems to be normal wear and tear... I think the XD type may be more durable and compatible with 1/12s as DaveS said.
I serviced mine last summer and didn't bother using special grease, the industry also recommends Slick Honey, but I went with a light nano oil that I use for precise mechanical parts of my work toolbox, it's light reduces friction and increases mobility improving the engagement of the rachets and does not thickens in cold weather, to be honest, I think that any seeing machine oil would to a good job. Most of the time these products (lubs) are produced for other purposes and relabeled for the bike industry and the price tag is double and tripled.


Good luck with whatever set you go, I'm sure it will put a smile on your face  ;D
