Miss Clementine Gets a Racktime Topit Front Rack

B. Second time's a charm to refit a Racktime Topit to a Rivendell Clementine.
After two wrench sessions and some creative engineering, the Racktime Topit front rack is installed on Miss Clementine. Before I explain the difficulties I encountered with fit, first let me present my view of front racks in general and how I expect them to carry a load.

History: In the past I've done extended tours with Blackburn low rider front rack in conjunction with a rear rack, distributing the weight approximately 30% front, 70% rear. In recent years, I prefer 50/50, still using the low rider front rack. Funny thing is, I've also lightened my gear since those lengthy tours plus cut back on riding days, now only gone for up to a week. My needs changed. I've explored using simple front racks like the Sunlite version attached to cantilever brakes, which have worked well on both my commuter bike and Miyata 610, allowing a 10 lb. load over the front wheel. 

Once the Clementine entered my house, though, I contemplated Rivendell's low cost alternative to front rack: a Wald basket (sans rack) using provided brackets attached to braze-ons near the wheel. While I like baskets, I preferred instead to use a rack for it's versatility and lighter weight. Benefits include the ability to mount small panniers and/or strap baggage on the platform. Thanks to various suggestions on RBW Google Groups, I contemplated other options, including the full coverage Soma Lucas alloy front rack. However, the Racktime Topit won out in the end due to attachment to mid-fork eyelets, an appealing trait, which reminded me of low riders, plus when I found the rack at half price, I couldn't resist. At the same time I ordered another Sunlite mini-rack, either as back up should the Topit not work, or as an alternative on another bicycle. 

Needless to say, the search for the perfect front rack - neither too heavy or costly, chrome-colored, and the ability to carry a sizable load - had become an obsession.

A. First attempt placed the rack at a steep angle.
I knew that Miss Clementine's geometry might pose fit problems, but initially it was my own undoing that sent me pleading to our LBS for help. I pre-screwed the first bolt into the front eyelet, knowing I needed to "crack" the frame's heavily painted threading, and when it proved a little difficult, continued until the bolt end sheared off, dropping to the kitchen floor. "Whaaaat?" I said, beside myself with horror. I was alone and unfortunately couldn't rely on my husband who's helped me out of sticky situations before. After a few deep breaths, I attempted to gently unscrew the protruding 1/4" of  bolt threads with pliers, trying to not completely shear off the remaining threads, worked at it for an hour, and eventually brought the bike in to a shop as a last resort.

A mechanic was, thankfully, able to remove the bolt using vice grips (now why didn't I think of that?). He said I'd stripped the threads on the end of the eyelet by screwing the bolt at an angle. However, for a few bucks they tapped both eyelets and repaired the damaged end by entering through the reverse side. Phew! Lesson learned!

A. This photo displays the longer bolt and spacer required to clear the rack from the rotating headset.
With a fiasco diverted, I installed the Racktime Topit following diagrams drawn on paper, the kind that lack written clues to accommodate multiple languages. With lower rack ends easily screwed into the mid-fork eyelets, I bought a longer bolt to accommodate fender support and top rack bracket, the later heavily bent in a vice to reach the position near the central hole in the fork, and with a spacer to clear the headset and V-brakes. It was a finely-tuned feat, and when admiring Miss Clementine from afar, I began to understand the rack's shortcomings in it's current configuration.  See two photos labeled "A" above for visual reference.

As my online research indicated, the Racktime Topit can sit traditionally lower, depending on where the mid-fork eyelets are positioned. However, it's not uncommon to see the rack propped higher, much like on Miss Clementine. If the rack platform is horizontal users have reported that hauling gear works out just fine without adversely affecting handling. I suspected however that a steeply angled front rack, as my first attempt turned out, panniers might be awkward and possibly shift while in transit.

It wouldn't be too terrible to live with it's current set up, but after thinking and scrounging in our collection of bike parts, I came up with a manageable retrofit.

B. Second time around, this fix should work (I think).
If you look closely at the photo above, you may recognize a pair of pre-twisted rear rack brackets refitted to Miss Clementine's fork crown's bolts, then afixed to the rack with plastic-coated P-clamps gleaned from left over rack parts. What I discovered, was there are numerous parts one can purchase to use the fork crown eyelets but they are proprietary and I couldn't locate accessories specific to the Topit. The P-clamp I used is a slightly larger diameter than I needed but smaller clamps of similar, as was explained to me "plasti-dipped" design are apparently unavailable in a hardware store (talk about proprietary!), so instead of searching further afield I layered the inside with a piece of bicycle tube which snugged the clamp nicely around the rack. The rack seems quite stable, though time will tell if the mechanism will hold up well under a touring load. What I particularly like about the new arrangement is it allows the rack to be separate from the fender attachment. Having two separate systems seems easier to fix should something go awry, especially if I'm away from home.

As an aside, the fork crown "eyelets" have always intrigued me, this being my first bicycle with this feature, though I didn't imagine I would use them quite so soon! It's a handy option, as I discovered, should you need another mounting point, and two points of contact as opposed to the one longer bolt through the fork should provide more stability to the rack.

To finish up the second wrench session, I replaced my terrible twine job with a couple wraps of leopard print duct tape that better suits my style.

With the new additions, Miss Clementine is feeling more like my own bicycle and developing a personality. I'm taking her on a bike overnight in two weeks so no better time like the present to try out her new front rack!

  1. I would put a washer behind the nut on the sliding clamps where you attached them to the P-clamps. It would provide a better bite and keep the nuts tight and prevent them from loosening. Just a thought.

    1. David, thanks for the suggestion. I though about adding a washer as I was installing the rack, but just wanted to finish the project! I can easily go back and fix it.

  2. is it any coincidence that Racking and Hacking are only one letter apart? way to stick it out.

    1. As difficult as it is for consumers to get a rack to fit I can't help but wonder how hard manufactures and designers have it - they need to create a rack that fits MOST bikes, all within a price point.

  3. I like the tape-wrapped center part for additional hand positions. Very nice.

    1. The bars are specifically made for the alternate hand position, however I find I am gripping the ergonomic grips 90% of the time because it feels so natural.

  4. You persisted and it looks like it payed off. Fork crown eyelets... that's a new one to me. Makes sense though.

  5. I've had a Racktime Topit in the bike box in the basement for about three years and never got around to installing it. I got it for the same reasons you did: reasonable price, good carrying capacity, and color. The plan was to put it on my Dutch bike, but when I did the rough fit it didn't look right at all. I ended up installing a simple handlebar basket on that bike and don't have another bike that is suitable for a front load. I like the idea of this rack, but I've heard from several people who found it challenging to install.

    1. The rack seems to be well thought out: lightweight and very strong. I don't think theTtopit is any more difficult to install than any other rack. In my opinion, all racks have peculiarities, but so do the bicycles! The marriage between both is often a rocky road...
