Shimano MT400-B hub. Ordered a new wheel and a magic mary. Is there any use for the old hub? I have no idea how to spoke and center a wheel.

If you have interest in learning to build wheels yes. If not donate it to a co op.
I wouldn’t bother – it’s a lower end hub from an OEM wheel. Unless you got an identical new front wheel, in which case you could re-use parts from that hub down the road (bearings, end caps), I’d just toss the whole thing. Keep the rotor, obviously.
The hub would be useful for a coop or if you donate it to a bike hobbyist or something, you can just offer the wheel as is for the hub basically. The tire should be fine unless there is bead damage not visible in the photo.
I mean I get it you’re on an ebike but at the same time, how’d you do that to a front wheel? It’s almost always back wheels that get wrecked.
From a Smart Sam to a Magic Mary is a massive move, are you riding down steep trails or at bike parks?
Thanks guys. So trash it is. Too bad. I didn’t budget for this expense.
TIL that 29 boost centerlock wheels are not that popular. 6 hole ones are way more available stock wise.
All parts are worth saving
I’ll take it
Save the hub if you’re using the exact same wheel as a replacement because if you damage a bearing it could save you money on parts. Just take cutters and cut the spokes throw away the rim.
1. buy the identical rim.
2. align and tape the new rim to the old rim.
3. move spoke and nipples one by one to the new rim.
4. make sure it’s mostly secure and either learn to true the wheel or bring it to a shop for the final assembly and truing.
Always, always keep hold of old components. They nearly always come in handy, whether for a future build or to help a friend out. You don’t know how to lace a wheel *yet*, but maybe it’s something you’ll want to try one day (it’s more accessible than people think). Sure, you probably don’t want to turn into a hoarder, but keeping a small storage box of parts is definitely worthwhile.
Speaking for myself, I would take it apart, measure & label the spoke lengths, and store it. I’ve been able to save a few wheels for friends and neighbor kids out of my parts bin. I’ve also been able to swap in a known good hub right before a trip when the old one crapped out.
It’s cheaper so buy a new one man tbh
Just keep it in your parts bin. Never know
Those Shimano hubs can be bought for about 10 – 20 depending on where you look.
They arent bad hubs at all but nothing fancy either.
Bike-discount.de if you’re in Europe, perhaps they ship globally too – really good prices for parts.
Lacing wheels is fun, I like to do it occasionally.
Yeah for sure. Cannibalize the hub and build a new wheel at the bike shop if your local has a truing stand.
I’d keep it and put it on a shelf. You never know when it may come in handy down the road. You may not know how to build a wheel but I’m sure you can figure out how to disassemble one.
Hub would be fine, rim is toast. Balance between time and money. – buying new again rather than having a go on repair is way more cost effective and logical in this situation.
