SDG's Eurobike display had more than seats in it this year, with the company expanding to cover a different contact point: your hands. Instead of a plastic barrel and slip-on aluminum collar, the new Slater grip sees both molded out of a single piece, with one inboard collar clamping the grip in place. SDG has employed some trickery to increase security, however, with a slight taper to the inner core from about the halfway point out to make for a tighter fit onto the handlebar. There are also small cutouts in the barrel so that the rubber makes contact with the handlebar for even more security, and to make the grip a bit more forgiving.

The Slater sports a small taper, going from 32mm at the ends to 30mm at the center, and they also have a slight oval shape to them to better fit hands.

Groms have a few pint-sized bikes to choose from these days, but all too often they're spec'd with adult-sized parts, including seats. SDG's grom-sized Fly Jr. isn't just a BMX seat or over-padded saddle that's been cut down but rather designed specifically for young'ns. The width measures 122mm, it's 235mm long, and SDG offers it in black, green, red, and cyan colors.

We saw photos of Box's revised shifter and new 7-speed downhill setup earlier this week via their press release, but I got to tinker with samples in their Eurobike booth today. The short cage One DH derailleur makes use of a massively stiffer clutch spring, and it's controlled with their fresh 7-speed Twin shifter that, like all of Box's shifters, features a more traditional two-paddle design over the PushPush system that we saw last year. There's also a matching 7-speed Box Two cassette that features an integrated spoke guard.

I expect downhillers to be more receptive to the idea of a non-Shimano/SRAM drivetrain than the average rider or racer, especially now that the brand has moved away from the PushPush shifter design, even if I think it worked quite well. Box might also be more likely to get some original equipment spec on the downhill side of things, or it's at least more likely to happen than them going up against a Shimano or SRAM for spec on all-mountain or enduro bikes.

Box's T-Channel gravity seat and post is sort of a cross between an I-Beam setup and a Pivotal BMX system, but with more angle adjustment than the former and more fore/aft range than the latter, according to Box's Toby Henderson. The seat's shell features a knurled slot that mates to the post's head, and the whole idea is to put ultimate strength at the top of the priority list.

There are no rails to bend or break, and Henderson said that the burly shell design means that there's not much in the way of flex, a fact that makes this particular seat better suited to downhill and bike park use than long days in the saddle. Just like Box's drivetrain components, the T-Channel seat and post come with a lifetime warranty.

Vee Tire Co.'s new Flow Rumba (no, I don't think it was named after the dance) has been designed as a do-it-all downhill tire that they say is "made with over 80% of downhill terrain in mind.'' The relatively closely spaced lugs look like they might make for a fast rolling tire, but also one that's probably not suited to thick mud - check the Flow Smasher pictured below for those mucky conditions. The Rumba is built with Vee's 52/48 'Tackee Compound' that they say is among the softest and slowest rebounding available, and that sticky rubber is laid over either their Enduro Core (1-ply combined with Apex) or Gravity Core (2-ply and Synthesis for three layers) casing, depending on your needs.

The Flow Rumba isn't yet available in huge widths, but the 2.35'' size can be had in both 26'' and 27.5'' diameters. Weights range from 1,150-grams to 1,250-grams.

A mud-specific tire can make all the difference in the world if you take the time to mount them up, but you probably have to be spending a fair bit of time in the muck to justify using them. The Flow Smasher is that kind of tire, however, with tall lugs that are widely spaced to penetrate and clear the goo. The same 52/48 Tackee Compound from the Flow Rumba is used to build the Smasher, but it's only available in a single 27.5'' x 2.4'' size and in the hefty Gravity Core casing. Claimed weight is 1,250-grams.

 Flow Smasher would be a great name for a couple of the local trailbuilders out here. "Let's put in a jump uphill right before this hard corner."

 LOL. I guess there is strong support for trail builder bashing. Should have know. This is PB.

 I think it depeds. If someone starts building in an area that has no trails at all and only few mtbrs it doesn't matter what he builds, it will always be better than nothing. But if someone starts changing a good trail and he knows that there are many riders, he just disregards other mtbrs without thinking of any consequences or difficulties

 I wouldnt put VEE rubber on my bike if it was given to me. I'm finding that Schwalbe has super weak sidewalls even with snakeskin.... maxxis likely next. Just cant handle the squirm in the corners anymore. Cool looking grips!

 does that vee tire rubber (52/4Cool correlate to a maxxis durometer of 42? If so, it's way too hard, which was my experience with vee - the rubber was more like hard plastic. The grip was terrible.
Also +1 for super gravity on the schwalbe.

 you obviously haven't run schwalbe tyres with super gravity sidewalls. conti and maxxis have thew weakest sidewalls that ive ridden. I have stretched two minion DHR 2's.

 @madmax245: try the dh cased conti, nothing has a stiffer and more supportive sidewall. Nothing is as reassuring in corners. Anything else I've tried is like wet towels, super g's next but initial tests are they are pathetic.

 I sure hope they're doing better than past efforts. I tried a Vee Rubber on the rear of my DH bike and after just one trip there were knobs that were missing and others that were peeling off their base!

They were on sale for dirt cheap! What does that tell you?

 WTB's TCS Tough casing is the real deal and any of their tires will last much longer than Schwalbes. They're also less like wrestling a bear to mount and remove.

 Maxxis DD casings are nice too.

 I have some skinny vee tyres for xc and fireroad fitness rides and they have exceeded my expectations in every way, I will be repurchasing if I can find them. Perhaps they are hit and miss depending on the tyre, but isn't this true of all the tyre manufacturers?

 SDG's grip tapers down in the middle?!??!? I love my Chromag Square Wave grips, they bulge in the middle, my hands don't get tired as fast with these grips when compared to a "flat" grip.
  • + 2
 I think they meant the inside of the grip so it gets tighter around the bar and doesn't spin.
  • + 1
 They're slightly ovalized to help fit the curvature of the hand on the grip. The grips do slightly taper down (32mm-30mm), but that's to act as a flange and keep your hands centered. Grips are internally tapered as well to give them a tighter fit on the bar and essentially eliminate slippage.

 So there is finally a 7 speed choice apart from sram. When will shimano release its 7 speed groupo? I always need to double shift my 10 speed zee, it is unnecessary as f

 You can easily set up a shimano system to shift into only 7spd. get some spacers for the cassette and set your limit screws properly. No need for a 7spd group.
  • + 1
 @leggatt: Its not quite a perfect solution as the range would be way too small. I am not a pro boy who rides at warp speed all the time.

 @Stanley-w: buy a larger geared cassette, then take off the 3 large cogs. An 11-36 10sp Shimano SLX cassette will leave you with 11-24 7sp when the last 3 are removed. That's pretty much the same range as a Sram 7sp casette, minus the 10t. Then, get a G-Sport BMX hub guard and use that as your backplate to prevent over shifting- it fits perfectly snug onto any Shimano freehub. Add a few casette spacers, tighten in your limit screws, and your golden.
Or you can get a OneUp or Hope freehub body, if you're running a Swiss or Hope hub respectively, and buy the hope DH cassette.

 @mtnbykr05: And cost wise this is almost the same as buying GX..I am planning on bodging a 6 speed kit for my 4x whip. Rather than buying conversion kits which are essentially just spacers I'll just use bottom bracket washers, which cost next to nothing.
  • + 1
 @Stanley-w: But you already have the zee R derailleur, and thus a shifter. The cassette is at most $60 at most shops, and the hub guard, maybe $15 (or free if you look around or find a good bmx shop). And yes, skip the conversion spacer kits, but most shops have 7speed cassette spacers and those are pennies on the dollar and thicker than BB spacers. Basically I'm just telling you that Shimano does have options (especially considering they've designed it to limit to 7speed) will be cheaper than buying an entire new drivetrain (even GX) and gives you virtually the same range. I'm nullifying your excuses because they suck.

Cassette on Jenson for $37
Hub Guard is $10 on Modernbike.com

And use spacers found at your LBS. Frankly idc if you use BB, cassette, or high-grade Sasquatch fur.

 @mtnbykr05: Yes, specific to my case you are absolutely right. But when I talked about lack of options I meant shimano simply doesnt offer optimised 7speed options equivalent to that of GX and x01 dh. I am not saying anyone should ditch their zee/saint for sram, I just believe GX/x01 are better options, if not the best ones.
