But don't forget, the weight on the rims are rotating and rotating mass is more than the normal mass.
I don't know how to say it in English, but with a wheel set which is 800g heavier you are slower. I could test it and that's the reason why I only have wheel sets <1500g

Definitely! Getting a 2200g wheelset up to speed is a lot more work than a 1500g set. The other part to that is the part that centrifugal force plays on the spinning wheel. A front wheel / tire  setup that weighs 400g more than another is going to be harder to get it to change direction. Think of spinning a toy top, the heavier it is, the longer it spins and the more stable it is. One of the main reasons why a light wheelset makes a bike "feel" lighter is because it is easier to move at high speeds.

But back to the cost vs weight vs purpose discussion, the 1725 gram 35mm wide wheelset on my wife's Tallboy feel's pretty light. It's not superlight but it isn't super heavy either and I feel we found a good balance between usage, weight, durability, and cost. We could have gotten it below 1600 grams just by using different hubs and not having Peter paint the rims but that would have cost us an extra $150 or more and put us over the $999 wheelset budget.

How many rings will it have up front? The more rings you have (1, 2, or 3) the further out the largest ring is. We need to know the effective chainline of the 50t ring to get an accurate measurement.

Thinking about getting an SRAM CX1 / 1x11. So it would be just the one 50T-Ring.

I would probably also go with an BSA-bb.
(Do the different Bottom Bracket have an significant difference in width - meaning the resulting chainline / distance to the frame?)

I highly doubt it will work with a 1x setup. For reference, I have the BSA bb with a SRAM GXP crankset / bottom bracket setup. The crankset is made for a 3x setup but I'm using the middle spot for the 32t ring and the outer spot for a bash ring. If I increased the diameter of the bash ring to match your 21cm measurement, it should work but will be very close. The downside is you would have to use the outer most option and the chain line really wouldn't work when you're in your granny gear. That being said, you might have to look at different frames or consider a different gear ratio as there is no way a 50t would fit in the middle ring option.

Hello!
New to the forum, new to 29"-bikes...

Planning on a new bike to build up over the year - so i'm collecting parts and infos at the moment.
The idea is to create something which i can use for touring, getting out and do quite some miles a day, without caring about the terrain - aka a Gravelgrinder.
Therefore I would like to use a big chainring, something around 50T to be able to put up some speed.
But Iam wondering:

Does the M-062 fit such an big chainring? The Diameter of a 50T chainring is ~21cm.
Would somebody who runs the frame, measure it and give me note if it would interfere with the frame or not?

Thanks and hello from germany.

It looks like the IS52/30 is for a straight steerer and I have a tapered steerer so the IS52/40 it is then.

You are correct. The /30 or /40 designation is based on the steerer tube of the fork. Straight steerer will take the 30 and a tapered will take the /40. Even if you get the wrong one the first time, they lower race / seal assembly is only $10 to $12 and can be purchased separately. It will make no difference on height.

Since I just relaced the wheels to some Crest MK3 rims, the original rims off of my SS are up for grabs. One is 32h and one is 28h and the internal width is 18mm and the ERD is 606 according to the DT Swiss page. They have 400 to 500 miles on them and are in great shape. The original black nipples are included too. Just cover the cost of shipping and an after ride beverage and they can be yours.

Carbon_dude,
I agree with most of that. I haven't had any experience with the DT line until I got the wheels for my SS which uses a 350 center lock straight pull hub. I couldn't take the 18 points so I got the 54t ratchet. I think I'm slowly converting to a DT 350 with 54t upgrade fan boy. Bang for the buck they are tough to beat. If you want bling and noise, then Hope takes the bang for buck prize. I just got some new M1800's wheels for my daughters bike. They are from 2013 but are new and were $200 shipped. Worst case scenario is that I got some 350 hubs for $200 bucks!

New wheels on the 062 Singlespeed. Weight dropped from 1765 grams to 1575 grams.

Total bike weight is down to 21.1 with heavy SLX trail pedals. My goal is to eventually get it below 20 with pedals but I think it's going to be tough without dropping a crap ton of money. I know the stem is one relatively cheap place I could save some weight as it's an OEM stem from my daughters GT Avalanche. The other place is the crankset. I could loose 100 to 150 grams by going with a Sram carbon direct mount setup or 250 grams with a RF NEXT sl crank. But those will be $200 or $400. The seatpost weighs in at 240g, I'm not sure I can save a whole lot there and still have some setback.

So with my wife's build almost wrapped up and starting to collect parts for the builds for my 2 daughters, I don't think there is much bike money left for me. 

Set 1 - Nextie 27.5 35mm outer / 29mm inner older hooked design, Hope Pro2 EVO 40t hubs, DT Comp spokes, DT ProLock brass nipples. 32 hole 3 cross. 3 seasons and well over 1,500 miles on them, many many rock strikes and even the occasional tree strike. Zero issues.

Set 2 - XMCarbonspeed 29 50mm outer / 43mm inner, Hope Pro4 Boost hubs, DT Aerolite spokes, DT ProLock brass nipples. 32 hole 3 cross. 400ish miles of semi rough riding. Still going strong without any issues.

Set 3 - XMCarbonspeed 29 35mm outer / 30mm inner, Hope Pro4 Boost hubs, Sapim CX-Ray spokes, Sapim double square aluminum self-locking nipples. 28 hole 2 cross. Going on the wifes Tallboy 3 and the rims haven't arrived yet.

Set 4 - Same as set 1 except they are on I9 hubs and belong to my brother. Under 1000 miles and zero issues.
